Monitoring Parameters Monitor CBC w/ differential and platelet regularly, LFTs, total bilirubin, CrCl, symptoms of infection; TPMT genotyping or phenotyping.
Adverse Reactions
Bone marrow depression (dose-related) characterised by anaemia, leucopenia, thrombocytopenia and rarely, aplastic anaemia, agranulocytosis, pancytopenia; reversible myelosuppression, megaloblastic anaemia, myelotoxicity, liver damage, GI disturbances, reversible alopecia, rashes, muscle and joint pains, rigors, fever, pneumonitis, tachycardia, pancreatitis, renal dysfunction, hypotension, Sweet's syndrome (acute febrile neutrophilic dermatosis).

Drug Interactions
Increased risk of infection w/ intra-uterine device and live vaccine. May potentiate neuromuscular blockade produced by depolarising agents (e.g. succinylcholine). May reduce neuromuscular blockade by non-depolarising agents (e.g. tubocurarine). May reduce anticoagulant effect of warfarin. Risk of haematologic abnormalities w/ ACE inhibitors, co-trimoxazole. Increased myelosuppressive effects w/ indometacin and cimetidine. Decreased rate of catabolism w/ xanthine oxidase inhibitors (e.g. allopurinol). Ribavirin may reduce efficacy and increase toxicity of azathioprine.
