Because of extensive metabolism, only a fraction of the radioactivity is present as Azathioprine. Williamson and Karp described an infant born with preaxial polydactyly whose mother received Azathioprine 200 mg daily and prednisone 20 mg every other day during pregnancy.6 Tallent et al described an infant with a large myelomeningocele in the upper lumbar region, bilateral dislocated hips, and bilateral talipes equinovarus. If this drug is used during pregnancy or if the patient becomes pregnant while taking this drug, the patient should be apprised of the potential hazard to the fetus. Renal clearance is probably not important in predicting biological effectiveness or toxicities, although dose reduction is practiced in patients with poor renal function. Prevention of post-operative recurrence is a challenge in clinical practice in Crohn's disease. The structural formula of Azathioprine is: It is an imidazolyl derivative of 6-mercaptopurine and many of its biological effects are similar to those of the parent compound. However, in some serious situations, the benefit of using this medication may be greater than the risk of harm to the baby. In the rat model of adjuvant arthritis, Azathioprine has been shown to inhibit the lymph node hyperplasia, which precedes the onset of the signs of the disease. Use in Pregnancy (Category D) The decision to maintain or discontinue azathioprine treatment during pregnancy, or to terminate the pregnancy, depends on the condition being treated, in which maternal wellbeing has to be weighed The frequency and severity of adverse reactions depend on the dose and duration of Azathioprine tablets as well as on the patient’s underlying disease or concomitant therapies.

"Successful pregnancies in women treated by dialysis and kidney transplantation." Azathioprine is immunosuppressive, delayed hypersensitivity and cellular cytotoxicity tests being suppressed to a greater degree than are antibody responses. As usual for patients with increased risk for skin cancer, exposure to sunlight and ultraviolet light should be limited by wearing protective clothing and using a sunscreen with a high protection factor. Discontinuation may be necessary for severe hematologic or other toxicity, even if rejection of the homograft may be a consequence of drug withdrawal. If the benefits of treatment with azathioprine (for instance, to maintain remission during pregnancy) outweigh the risks, this drug may be continued during pregnancy. Azathioprine has been reported to cause temporary depression of spermatogenesis in mice.Benefit versus risk must be weighed carefully before using azathioprine in patients of reproductive potential.

Physicians are encouraged to register patients by calling 1-215-955-4820 (USA).AU TGA pregnancy category D: Drugs which have caused, are suspected to have caused or may be expected to cause, an increased incidence of human fetal malformations or irreversible damage. Leucopenia and/or thrombocytopenia have been reported in a proportion of neonates whose mothers took azathioprine throughout their pregnancies. The use of ribavirin for hepatitis C in patients receiving Azathioprine has been reported to induce severe pancytopenia and may increase the risk of Azathioprine-related myelotoxicity. Patients who are heterozygous for both TPMT and NUDT15 deficiency may require more substantial dosage reductions (see CLINICAL PHARMACOLOGY, WARNINGS: Cytopenias, and PRECAUTIONS: Laboratory Tests). Death associated with pancytopenia has been reported in patients with absent TPMT activity receiving Azathioprine. Physicians using this drug should be very familiar with this risk as well as with the mutagenic potential to both men and women and with possible hematologic toxicities. Whenever possible, use of IMURAN in pregnant patients should be avoided. In addition, each tablet contains the following inactive ingredients: croscarmellose sodium, lactose monohydrate, magnesium stearate, povidone and starch. However, acute myelogenous leukemia as well as solid tumors have been reported in patients with rheumatoid arthritis who have received Azathioprine. Avoiding breastfeeding for 4 to 6 hours after a dose should significantly reduce the dose received by the infant in breast milk. Azathioprine tablets may be continued long-term in patients with clinical response, but patients should be monitored carefully, and gradual dosage reduction should be attempted to reduce risk of toxicities. This is not an estimate of the half-life of Azathioprine itself, but is the decay rate for all 35S-containing metabolites of the drug. Postmarketing cases of hepatosplenic T-cell lymphoma (HSTCL), a rare type of T-cell lymphoma, have been reported in patients treated with Azathioprine. Azathioprine and long-wave ultraviolet light have been shown to have a synergistic clastogenic effect in patients treated with azathioprine for a range of disorders. Consider testing for TPMT and NUDT15 deficiency in patients who experience severe bone marrow toxicities. Azathioprine and mercaptopurine are FDA Pregnancy Category D. Where possible, these drugs should not be taken during pregnancy, except where the benefits outweigh the risks. The TPMT*2, TPMT*3A, and TPMT*3C alleles account for about 95% of individuals with reduced levels of TPMT activity. 1987. Schusziarra V, Ziekursch V, Schlamp R, et al.
