States’ and localities’ efforts to expand naloxone distribution provide another example of building a comprehensive order voveran sr 100mg without a prescription, multipronged buy voveran sr 100mg without prescription, community infrastructure purchase 100 mg voveran sr with amex. Many communities have recognized the need to make this potentially lifesaving medication more widely available. For example, community leaders in Wilkes County, North Carolina, implemented Project Lazarus, a model that expands access to naloxone for law enforcement, emergency services, education, and health services, and reduced the county overdose rate by half within a year. North Carolina also passed a law in 2013 that implemented standing orders, allowing naloxone to be dispensed from a pharmacy without a prescription. A few states have passed legislation to make naloxone more readily available without a prescription if certain procedures are followed. This program was expanded to all interested pharmacies in 2013 and formalized in regulation in 2014. The need to engage individuals in services to address their opioid use is a critical next step following an overdose reversal. This becomes increasingly challenging as naloxone kits are distributed widely, rather than when distribution is limited to health care and substance use disorder treatment providers. In 2013, the State of Vermont implemented an innovative treatment system with the goal of increasing access to opioid treatment throughout the state. This model, called the “Hub and Spoke” approach, met this need by providing physicians throughout the state with training and supports for providing evidence-based buprenorphine treatment. Recommendations for Research A key fnding from this chapter is that the traditional separation of specialty addiction treatment from mainstream health care has created obstacles to successful care coordination. Research is needed in three main areas: $ Models of integration of substance use services within mainstream health care; $ Models of providing ongoing, chronic care within health care systems; and $ Models of care coordination between specialty treatment systems and mainstream health care. In each of these areas, research is needed on the development of interventions and strategies for successfully implementing them. Outcomes for each model should include feasibility, substance use and other health outcomes, and cost. Although a great deal of research has shown that integrating health care services has potential value both in terms of outcomes and cost, only a few models of integration have been empirically tested. Mechanisms through the Affordable Care Act make it possible to provide and test innovative structural and fnancing models for integration within mainstream health care. This research should cover the continuum of care, from prevention and early intervention to treatment and recovery, and will help health systems move forward with integration. Studies should focus on patient-centered approaches and should address appropriate interventions for individuals across race and ethnicity, culture, language, sex, sexual orientation, gender identity, disability, health literacy, and for those living in rural areas. So as not to limit health care systems to services for those with mild or moderate substance misuse problems and to offer support for individuals with severe problems who are not motivated to go to specialty substance use disorder treatment, it is also important to study how to implement medication and other evidence-based treatments across diverse health care systems. This chapter pointed out that when substance use problems become severe, providing ongoing, chronic care is required, as is the case for many other diseases. Little research has studied chronic care models for the treatment of substance use disorders. Research is needed to develop and test innovative models of care coordination and their implementation. Finally, the chapter pointed out the gap in our understanding of how to implement models of care coordination between specialty addiction treatment organizations and social service systems, which provide important wrap-around services to substance use disorder patients. This area of research should involve institutions that provide services to individuals with serious co-occurring problems (specialty mental health agencies), individuals with legal problems (criminal justice agencies and drug courts), individuals with employment or other social issues, as well as the larger community, determining how to most effectively link each of these subpopulations with a recovery-oriented systems of care.

It has been well documented in the medical field that effec- tive communication with patients leads to better diagnosis and treatment, as well as an improved provider–patient relationship. Although most of this research is related to 5 12 chapter 1 / the patient interview physician–patient communications, it can easily translate to communications between the pharmacist and the patient. This is because pharmaceutical care, like the care pro- vided by a physician, involves (1) curing a patient’s disease, (2) eliminating or reducing a patient’s symptoms, (3) arresting or slowing a disease process, and (4) preventing a disease or symptoms. Even though a pharmacist does not make disease diagnoses like 6 physicians do, a pharmacist must nonetheless evaluate the information obtained from the patient interview, including the possibility of certain diagnoses, to appropriately create an assessment and plan, which may include a referral to the patient’s physician or an emergency room for further evaluation. This is typically documented in the patient’s own words and is therefore quoted in the written or oral presentation. One way to deter- mine the patient’s chief complaint is by asking, “What brings you here today? In the case of no overt complaint, the chief complaint may be goal-oriented, such as “I am here to pick up my refills,” “I am here to discuss my labs,” or “My doctor told me to see you about my sugars. For example, a patient may come in complaining of “being out of his furosemide” and, upon evaluation, it may be determined that the patient is experiencing acute heart failure. This assessment and the subsequent plan will be discussed elsewhere in your documentation. History of Present Illness The history of present illness (hpI) is the story of the illness. The pharmacist will 7 further explore the chief complaint as well as any other potential problems by asking questions about any recent or remote history that may be related to the current illness. Seven attributes need to be addressed to obtain a well- characterized description of the complaint or symptom: location, quality, quantity or severity, timing, setting, factors that aggravate or relieve the symptoms, and associated manifestations. For example, if the patient much worse is it now than it is in pain, characterize the pain by using normally is? If “Would you say that this the symptom is pain, ask the patient to swelling is causing your leg to rate the pain on a scale of 1 to 10. Setting This includes addressing the possible “Have you noticed what cause of the symptom. Do you relieve the or nonpharmacologic therapies used to notice a difference in the symptom relieve the symptoms and their efficacy. Are you experienc- that may be a consequence of the primary ing any shortness of breath or symptom. For example, if a patient complains of a cough, it is not necessary to ask about the “location” of the cough. However, if a patient complains of a headache, specifying the exact “location” of the pain (i. A patient who is telling you parts of his or her story may not realize which parts are pertinent. For example, the patient may not know how and what information needs to be relayed to you so that you can make a complete assessment. It is like a puzzle in that you may know what the completed puzzle will look like; however, you have to pick up each piece; examine its shape and color for hints, such as having a flat side, which indicates that it is a border piece; and then place it near other “like” pieces until you are able to fit all the pieces together. You, as the pharmacist, should start thinking of various questions to ask the patient so that the patient’s responses, or the puzzle pieces, may be put together to ascertain or rule out certain assessments. In the case of the patient interview, you will be assessing each piece of information for its reliability, completeness, and relevance to the problem. You may need to assess a patient’s medical condition during the patient interview even if the patient does not have any complaints regarding that medical condition. If the patient has any of the aforementioned symptoms, they would be termed pertinent positives, or the presence of symptoms that are related to the medical the patient interview 15 condition that is being assessed. In contrast, if these symptoms are absent, they would be termed pertinent negatives, or the absence of symptoms related to the medical condition being assessed. Asking these focused questions about pertinent positive and negative symptoms contributes to the assessment of heart failure in this patient.

Infection by the human immunodeficiency virus leads to gradual and progressive destruction of the cell mediated immune system. Diagnosis  Fever, diarrhoea, weight loss, skin rashes, sores, generalized pruritis, altered mental status, persistent severe headache, oral thrush or Kaposi’s sarcoma may be found in patients with advanced disease  Most patients, however, present with symptoms due to opportunistic infections e. Followed by a complete blood count, renal and hepatic chemical function tests, urine pregnancy test and viral load where applicable should be done at baseline. Initiation of treatment should be based on the extent of clinical disease progression. General orientation of the patient and family members should include:  Who to call and where to get refills  Who to call and where to go when clinical problems arise  Who to call/where to go for assistance on social, spiritual and legal problems that might interfere with adherence to treatment 1. It is important to remember that there is no single combination that is best for every patient and/or that can be tolerated by all patients. Regimens should be recommended on the basis of a patient’s clinical condition, lifestyle, and ability to tolerate the regimen. In the first two weeks of treatment only half of the required daily dose of Nevirapine should be given, and a full dose if there are no side effects such as skin rash or hepatic toxicity. Renal function should be monitored through routine urine testing for the occurrence of proteinuria and if available serum creatinine. Second category: Symptoms are somewhat more severe and often respond to some medical intervention. They include more severe gastric upset with nausea and vomiting, more severe headaches and mild peripheral neuropathy that does not incapacitate or interfere with a patient’s lifestyle. These symptoms can often be successfully treated with anti-emetics, anti- diarrhoea medicines, analgesics, neuroleptics (e. The rash can occur in up to 20 % of patients and usually occurs in the first 6-8 weeks of therapy. Note:  If a mild drug-reaction type rash occurs, patients will continue treatment with caution and careful monitoring. This rash will be treated with patient assurance, antihistamines and close follow up until resolved. Hypersensitivity symptoms include: flu symptoms, shortness of breath, cough, fever, aches and pains, a general ill feeling, fatigue/tiredness, swelling, abdominal pain, diarrhoea, nausea, muscle or joint aches, numbness, sore throat or rash. Patients may benefit from assurance that these symptoms are common and will decrease over time. Stavudine (d4T) Side effects Peripheral neuropathy is a common side effect with the use of Stavudine and occurrence of lactic acidosis has been reported. Cumulative exposure to d4T has the potential to cause disfiguring, painful and lifethreatening side-effects, such as lipodystrophy and lactic acidosis; for 336 | P a g e patients who are still on d4T; prescribe 30 mg every 12 hours for all individuals, irrespective of body weight. It results from failure to suppress viral replication with the development of viral resistance. In Tanzania, immunological and clinical parameters are used to identify treatment failure. However, in light of declining costs of performing viral load measurements, along with the simplification of processes, where available, viral load parameters should also be applied. Each of the above scenarios could result in sub-therapeutic drug levels and poor clinical response. In such cases, the regimen in question may be salvaged with palliative medication and/or patient education. If clinical assessment indicates the presence of treatment failure due to confirmed drug resistance, the best approach is to switch to an entirely new regimen, choosing two or more drugs to which the patient is naive as the second line drug regimen. Before changing to the second line drug regimen, the patient needs to go through the treatment readiness and education process again. This needs to be carefully monitored as some patients might hide their non-adherence. This may also compensate for any possible reduction in the effectiveness of the hormonal contraceptive. Generally:  Patients that are controlled on their antiretroviral medication at appropriate doses should continue on the same regimen if possible. Note: Boosted Atazanavir has no interaction with Methadone, is well tolerated and has high genetic barrier to resistance development. Moreover, pharmacokinetic parameters in children vary with age and therefore are more complicated than in adults. The use of tablets that require cutting in order to use a portion of the drug should be discouraged as it can lead to under dosing or overdosing of the drug. Drug doses must be adjusted as the child grows in order to avoid risk of under dosage, resistance to drugs and sub optimal response. Standardization is also important so that non-expert personnel can safely dispense correct 339 | P a g e doses. It is therefore preferred to provide health care workers with job aids such as dosing charts or dosing wheel that can be administered according to weight bands. Evaluation to be done before initiating therapy in children A good history of the patient should be taken together with a thorough physical examination.

When possible, therapeutic drug monitoring should be utilized for those medications where serum drug concentrations can be obtained in a clinically relevant time frame 5. Trends in renal function indices such as serum creatinine and urine output along with volume status should be utilized to guide drug dosing when rapidly measurable indices are unavailable 6. Formulation and validation of rapid and reliable direct measurement methods or estimating formulas for kidney and liver function are definitively needed to prospectively ascertain the trajectory of the patient’s kidney or liver function 3. If estimating equations are to be used, these should be validated against measured values determined via state-of-the-art standard techniques for assessing kidney function 5. Encourage further development of electronic tools/decision-making software to guide drug dosage individualization and detect, ascertain causality, and prevent drug interactions 9. Develop a longitudinal medication history to aid in the identification of residual effects of drugs on the pharmacokinetics, dynamics as well as the patient’s sensitivity to the development of adverse events 11. Mandate changes in drug labeling to reflect measurement techniques used for establishing the patient’s organ clearance that are the foundation of drug dosing individualization 5. Because of the above limitations, the recovery clearance to four plasma concentrations should be obtained during approach remains the benchmark for the determination of dialysis.

The dose should be given after dialysis (Dhd) to ensure active drug levels until next dosing. Consider a supplementary (Dsup) dose in addition to the dose adjusted to kidney failure (Dfail) after dialysis to replace the fraction removed by dialysis (Fr) Dhd=Dfail+Dsup where Dsup=Fr (DstartÀDfail) 2. The Dsup derived from studies of low-flux nonsynthetic membranes should empirically be increased by at least 50% when patients are dialyzed with high-flux synthetic dialyzers 3. Extended dialysis regimens with high diffusive membranes have been associated with extensive drug clearances and thus the Dsup may need to be increased Research 1. Develop methodologies to quantitate the degree of drug adsorption to the dialyzer membrane and associated elements in the extracorporeal circuit as this route of drug removal impacts the overall dialyzer clearance 3. The dialyzer model and all the components of the dialysis prescription should be reported for each individual studied. The dialysis prescription should be standardized as much as clinically feasible to enhance the generalizability of the data 5. The time course and the extent of the postdialysis rebound in drug serum concentrations should be assessed and the resultant data incorporated into the drug dosage regimen recommendation Regulatory 1. In vitro and in vivo dialysis studies should use a standard array of model substrates such as creatinine, vitamin B12 or vancomycin, and b2-microglobulin. The Several modes of therapy (convective, diffusive, or both), a mode of therapy (diffusion, convection, or both) can be variety of filter materials, and different effluent flow rates are influential, as both therapy modes can remove small solutes, 111,119 but convective therapies are superior at removing larger used, all of which can influence drug removal. Filter composition can 145,146 continuous venovenous hemofiltration studies specified also influence drug removal. The most effective dosing optimization strategy is to use therapeutic drug monitoring for drugs like aminoglycosides and vancomycin to achieve the desired therapeutic goals. The effect of other extracorporeal techniques should be investigated in terms of their ability to remove/adsorb drugs 5. Intermittent antibiotic dosing has not been unequivocally successful in eradicating bacterial growth, partially questioning the concept of antibiotic back diffusion into the peritoneal cavity. Transperitoneal drug movement may be less effective in the post acute phase of peritoneal infection when inflammation-related capillary hyperperfusion subsides 3. Monitoring of dialysate concentrations may provide even more relevant information Research 1. Peritoneal dialysis drug clearance may need to be characterized for many more drugs than in the past due to the introduction of high- and continuous-flow peritoneal dialysis variants, which are likely to become available for both acute and chronic patients in the foreseeable future 3. Although the intraperitoneal route is a well-established administration mode for some agents, especially antibiotics in patients with peritoneal dialysis-associated peritonitis, several aspects of this dosing approach require further research. These include assessment of the degree of equivalence of drug absorption across a noninflamed vs. Simulation studies of bidirectional transperitoneal drug transport would be particularly relevant in intermittently treated patients on automated peritoneal dialysis, in whom alternating phases of rapid nocturnal cycling and daytime rest might result in complex pharmacokinetic patterns 5. Finally, the efficacy and safety of intermittent and continuous dosing protocols should be studied in clinical trials Regulatory 1. The degree and rate of drug patients treated by automated peritoneal dialysis with transport across the peritoneum depends on the dialysate frequent short dialysis cycles, exposure to peritoneal dialysis volume in which the drug is diluted, the dialysate to plasma fluid with a given antibiotic concentration over several cycles concentration gradient, the molecular size and electrochemi- may result in higher plasma concentrations as compared with cal properties of the drug, the exposure time, and the antibiotic loading in a single extended dwell period in 155 peritoneal perfusion rate.

New models will thus initially err towards stricter discount voveran sr 100mg fast delivery, more intrusive regulation discount 100 mg voveran sr, with lower restriction levels only subsequently coming into play buy 100 mg voveran sr overnight delivery. A precautionary and incremental approach allows for key concerns, such as availability to youth, increase in high risk behaviours or other specifc public health concerns, to be closely monitored. If problems do arise, policy can take a step back, be refned and adjusted, and alternative or additional regulatory tools can be deployed. Additionally, such an approach has democratic benefts, in that it allows for greater civil society involvement in policy development. It also goes some way to removing the fear that all drugs would somehow just become available ‘overnight’. By demonstrating that policy is being developed in a responsible and cautious fashion, based on evidence of effectiveness and sensitive to legitimate fears and concerns, it offers the opportunity to win a greater level of public and political support for a programme of reform. Such a cautious, measured approach will also help placate critics, who fear that moves towards regulation are a ‘gamble’, un-evidenced or in some way ‘reckless’. A useful precedent for this is provided by some of the more contentious harm reduction policy developments of the past two decades, such as needle exchanges, supervised injecting venues, or opiate prescribing. Due to the highly charged political environment around drugs issues, such interventions have been subject to unprecedented regulation and scrutiny. Particular attention has been given to their effectiveness in reducing health harms, and to high profle concerns that they can somehow encourage use. Responses to such scrutiny have demonstrated 68 4 5 6 Making a regulated system happen Regulated drug markets in practice Appendices how effective policy interventions can be developed, public concerns can be dealt with sensitively, sensationalist media coverage responded to intelligently, and political opposition ameliorated. The increments along which phased change can be implemented are essentially in line with the range of regulatory tools described in chapters two and three. There is the potential to move from greater to lesser levels of regulation, controlling the levels of availability either through deployment of the different regulatory controls over suppliers, purchasers and products, or through their deployment at varying inten- sities. Where possible the longer term aim would be to encourage and move from legal/administrative controls towards social controls. Different countries will necessarily take different approaches, and see their policy and legal infrastructure develop along different routes. There will, for example, be very different challenges faced by primarily producer, transit or consumer countries, states with different levels of economic resources, political stability and public health and enforce- ment infrastructure, and states that are geographically isolated, compared to those with large borders with highly populated regions. Cannabis is likely to be the frst drug to have regulatory models more seriously explored. At the other end of the spectrum, around problematic dependent use of opiates and stimulants, we are likely to see medicalised maintenance 29 R. Newcombe, ‘Attitudes to drug policy and drug laws; a review of the international evidence’, Transform Drug Policy Foundation, 2004. These models will be based on already established, functional and effective interventions in numerous countries. These two emerging trends are already defning an ongoing pragmatic reform process —addressing the areas of most pressing practical necessity where prohibition’s effects are the most egregious, in population terms (cannabis) and overall harm creation (chaotic use/dependence). Within broad groupings of similar types of drugs—stimulants, depres- sants or hallucinogens (see: chapter 5)—we might reasonably expect regulated legal availability pilots to begin by focussing on the drugs least likely to be associated with personal or social harms and costs (see: 4. Similarly, less potent preparations of drugs, for use through lower risk methods of administration, could be made available in the frst instance. First, such rankings should inform policy makers, so that they can develop effective, targeted and proportionate policy responses to a range of different drug harms, which can thereby be managed and minimised. This is an essential element of developing effective regula- tory frameworks and inevitably requires a degree of population based generalisation. The second is to facilitate the education of individuals about drug risks and harms, so enabling them to make informed and responsible decisions about their health and wellbeing. Getting to grips with these questions requires that two important 70 4 5 6 Making a regulated system happen Regulated drug markets in practice Appendices distinctions are made. First of all, primary health harms to individual users should be distinguished from the secondary social harms to third parties that follow from that use. Second, harms related to drug use per se (both primary and secondary) should be distinguished from harms created or exacerbated by policy environments. The prevailing analysis that informs most current policy makes the frst distinction (between health and social harms) reasonably well, but largely fails to make the second distinction (between drug harms and policy harms). It confuses and confates the two, often misattributing prohibition or illicit market harms to drugs, or by default drug users, and feeding the self-justifying 30 feedback loop that has helped immunise prohibition from scrutiny. Some efforts to untangle drug use harms from drug policy harms have been made, although this is an area that warrants more detailed consid- eration and analysis. Correspondingly, the Transform report then makes a distinc- tion between the aims of the drug policy reform movement—to reduce or eliminate the harms specifcally created or exacerbated by prohibi- tion and illicit markets—and the more conventional aims of an effective drug policy—to reduce or eliminate the range of direct and indirect harms associated with drug use and misuse. A more comprehensive ‘taxonomy of drug-related harms’ has been 32 constructed by MacCoun and Reuter who break down forty six iden- tifed drug-related harms into four general categories: ‘health’, ‘social and economic functioning’, ‘safety and public order’, and ‘criminal justice’. Whilst these systems have some functionality, they are frequently both inconsistent and oversimplifed. On a practical level, they are built on generalisations, they (confusingly) fail to include legal drugs, and both confate and fail to fully acknowledge multiple harms; this has substantially reduced their utility, both as policy making tools, and as aids to individual users seeking to make informed decisions about personal drug use. Before discussing these issues and their policy implications in more detail it is worth trying to deconstruct the main vectors of harm associ- ated with drug use specifcally (as distinct from harms related to drug policy) that policy makers must consider. The level of risk associated with a given drug’s toxicity and propensity to cause dependence is then moderated by a series of behavioural variables, and by the predispositions of the individual user. A drug’s acute toxicity relates to the size of the margin between an active threshold, the dose at which the drugs effect (or desired effect) is achieved by the user, and the dose at which a specifed toxic reaction, or overdose, occurs. Such a toxic reaction could involve merely unpleasant temporary side effects, such as vomiting, dizziness, fainting, distress, etc. The comparable terminology for medical drugs is the ‘therapeutic index’, which is the ratio of the therapeutic dose to the toxic dose. With non-med- ical drugs acute toxicity of a given drug is often measured by assessing the ratio of lethal dose to the usual or active dose.

Pregnancy outcome after in utero exposure to itraconazole: a prospective cohort study. These have presumably been the result of reactivation of a previously acquired infection. This diagnosis can be difficult to distinguish from a bacterial community-acquired pneumonia; patients present with symptoms that include cough, fever, and pleuritic chest pain. The syndromes other than focal pneumonia usually occur in more immunosuppressed patients. Diffuse pulmonary disease presents with fever and dyspnea and can be difficult to clinically distinguish from Pneumocystis pneumonia. Routine bacterial cultures from pulmonary secretions frequently reveal Coccidioides after an incubation time of less than one week. Blood cultures are positive in a minority of patients, usually those with diffuse pulmonary disease. Unlike other endemic mycoses, Coccidioides grows relatively rapidly at 37°C on routine bacterial media, especially blood agar. Growth of a non-pigmented mould may be observed in as few as 3 days and can be confirmed as Coccidioides by gene probe. Coccidioides growing on an agar plate is a significant laboratory hazard because of the risk of inhalation of dislodged arthroconidia. Laboratory personnel should be alerted to the possibility of Coccidioides at the time the specimen is sent to the laboratory, and the plate lid securely taped. Most commonly, the diagnosis of coccidioidomycosis is based on a positive coccidioidal serological test associated with a compatable clinical syndrome. Patients with past coccidioidal infection without disease activity usually have negative serological tests. The first was the development of a precipitate in a tube when incubated with a heat-stable coccidioidal antigen preparation. It is due to an IgM antibody reaction, is not titratable, not useful in the diagnosis of meningitis, and is positive early in disease. The second reaction originally detected the loss of serum complement activity in the presence of a heat-labile coccidioidal antigen preparation. It has been shown to detect antigen in urine,15 serum16 and other body fluids in samples from individuals with active coccidioidomycosis. A recent study suggests that detection of coccidioidal antigen in the cerebrospinal fluid has a very high sensitivity and specificity for diagnosing coccidioidal meningitis. Testing is also advised for individuals who have traveled to or lived in endemic areas in the past. Trough serum levels should be measured to ensure efficacy and avoid toxicity; a level of 1-5 mg/L is desired. Several dosage formulations of posaconazole have been studied for coccidioidomycosis. If intrathecal therapy is required, it should be administered by someone very experienced in this technique. A rise suggests recurrence or worsening of clinical disease and should prompt reassessment of management. Table 5 lists such interactions and recommendations for therapeutic drug monitoring and dosage adjustments, where feasible. Drug interactions may limit the use of voriconazole in patients who are taking non-nucleoside reverse transcriptase inhibitors or ritonavir or cobicistat-boosted regimens (see Table 5). For patients with diffuse pulmonary disease and those with extrathoracic dissemination, antifungal therapy should continue for at least 12 months and usually much longer. Discontinuation of therapy should be based on clinical and immunological response in consultation with an expert. Continued monitoring during coccidiomycosis therapy and after such therapy has been discontinued with clinical follow-up, serial chest radiographs and coccidioidal serology every 3 to 6 months should be performed. Special Considerations During Pregnancy Women are generally at less risk than men for severe coccidioidomycosis and disease does not appear to worsen in women with prior coccidioidomycosis during pregnancy. However, coccidioidomycosis is likely to be severe and disseminated if infection is acquired during the second or third trimester of pregnancy. One registry-based cohort study (included in the systematic review)41 and a more recent large population-based case-control study42 specifically noted an increase in conotruncal heart defects. In addition in a nation-wide cohort study from Denmark oral fluconazole in pregnancy was associated with an increase risk of spontaneous abortion compared to unexposed women or those with topical azole exposure only. Based on the reported birth defects, the Food and Drug Administration has changed the pregnancy category from C to D for fluconazole for any use other than a single, 150 mg dose to treat vaginal candidiasis (http://www. Although there are case reports of birth defects in infants exposed to itraconazole, prospective cohort studies of over 300 women with first trimester exposure did not show an increased risk of malformation. For such situations, the decision regarding choice of treatment should be based on considerations of benefit versus potential risk and made in consultation with the mother, the infectious diseases consultant, and the obstetrician. Extensive clinical use of amphotericin B has not been associated with teratogenicity. Use in consultation with a specialist and should be administered by a clinician experienced in this technique. Table 5 lists these interactions and recommends dosage adjustments where feasible.
