Discuss the benefits and side effects of treatment with the patient/carer, including providing the patient with information leaflets and a monitoring record book if required. If appropriate, patients should be advised about the impact of treatment on fertility, pregnancy and breastfeeding. Men planning to conceive should also receive appropriate counselling. Undertake baseline tests including weight, blood pressure, ALT (or AST), eGFR, CRP, chest X-ray and TMPT levels) prior to starting therapy. Advise patient to be vaccinated against pneumococcus and influenza infection (via GP). Notify the patients GP that treatment has started and inform results of baseline tests. Prescribe azathioprine until a stable dose is reached and blood tests are stable for three months. Contact the GP to ask whether he or she is willing to participate in shared care (once the patient is stable). Shared care can only commence when GP written consent has been received Discuss the shared care arrangement with the patient so that the patient/carer is clear what needs to be monitored and when. Where applicable advise patient treatment is off-label Dose stabilisation: initial dosage adjustment until stable. Thereafter, during maintenance treatment, advice to the GP on any further dose adjustments required. If dose and bloods are stable for 3 months the GP, if agreeable, can monitor the patient as below Periodically review the patient’s condition and communicate promptly with the GP when treatment is changed. Have a mechanism in place to receive rapid referral of a patient from the GP in the event of deteriorating clinical condition. Advise the GP on stopping treatment (if appropriate). Report serious adverse events to the MHRA and GP Ensure that clear backup arrangements exist for GPs to obtain advice and support. General Practitioner responsibilities Reply to the request for shared care as soon as practicable. File copy in patient’s record and add shared care – specialist/GP read code 66S2 or XaK6z depending on GP clinical system. Ensure compatibility with other concomitant medication and prescribe azathioprine at the dose recommended. Once patient is stable and shared care has been agreed, monitor patient as below. Adjust the dose as advised by the specialist. Report to and seek advice from the specialist on any aspect of patient care that is of concern and may affect treatment. Refer patient to the specialist if his or her condition deteriorates. Stop treatment on the advice of the specialist or immediately if an urgent need to stop treatment arises. Report adverse events to the specialist and MHRA. SUPPORTING CLINICAL INFORMATION Dosage and Administration Azathioprine is available as tablets containing 25mg or 50mg. Azathioprine should be taken with or immediately after food. The usual dose is from 1 to 3mg per kg per day, adjusted according to response. Contraindications Azathioprine is contra-indicated in patients known to be hypersensitive to it. Hypersensitivity to 6-mercaptopurine (6-MP) should alert the prescriber to probable hypersensitivity to azathioprine. Azathioprine therapy should not be initiated in patients who may be pregnant, or who are likely to become pregnant without careful assessment of risk versus benefit. Side Effects Very common - Depression of bone marrow function; leucopenia, viral, fungal, and bacterial infections, thrombocytopenia. Uncommon – cholestasis and degeneration of liver function tests, pancreatitis, anaemia. Rare – alopecia, photosensitivity, life threatening hepatic damage, colitis, diverticulitis and bowel perforation reported in transplant population; severe diarrhoea in inflammatory bowel disease population. Agranulocytosis, pancytopenia, aplastic anaemia, megaloblastic anaemia, erythroid hypoplasia. Neoplasms including non-Hodgkin's lymphomas, skin cancers (melanoma and non-melanoma), sarcomas (Kaposi's and non-Kaposi's) and uterine cervical cancer in situ, acute myeloid leukaemia and myelodysplasia Very rarely causes reversible pneumonitis, Xxxxxxx-Xxxxxxx syndrome and toxic epidermal necrolysis. A hypersensitivity reaction has been uncommonly reported which includes general malaise, dizziness, nausea, vomiting, diarrhoea, fever, rigors, exanthema, rash, vasculitis, myalgia, arthralgia, hypotension, renal and hepatic dysfunction and cholestasis. Following a hypersensitivity reaction, careful consideration should be given to restarting treatment with azathioprine. Monitoring FBC, creatinine / eGFR, ALT (or AST) and albumin every 2 weeks until dose and monitoring stable for 6 weeks; thereafter monthly for three months, then at least every 12 weeks. Dose increases should be monitored by FBC, creatinine / eGFR, ALT (or AST) and albumin every 2 weeks until on stable dose for 6 weeks then revert to previous schedule. Action required if abnormal results Contact specialist team urgently and consider interruption in treatment if any of the following develop: • WCC <3.5 x109/L • Neutrophils <1.6 x 109/L • Unexplained eosinophilia >0.5 x 109/L • Platelet count <140 x 109/L • MCV > 105 f/L • Creatinine >30% above baseline and/or calculated GFR <60 • ALT and/or AST >100 units/L • Unexplained fall in serum albumin Drug Interactions Xanthine oxidase activity is inhibited by allopurinol, oxipurinol and thiopurinol which results in reduced conversion of biologically active 6-thioinosinic acid to biologically inactive 6-thiouric acid. When allopurinol, oxipurinol and/or thiopurinol are given concomitantly with 6-mercaptopurine or azathioprine, the dose of 6-mercaptopurine and azathioprine should be reduced to one-quarter of the original dose. Inhibition of the anticoagulant effect of warfarin, when administered with azathioprine, has been reported. Where possible, concomitant administration of cytostatic drugs, or drugs which may have a myelosuppressive effect, such as penicillamine, should be avoided. There are conflicting clinical reports of interactions, resulting in serious haematological abnormalities, between Imuran and co-trimoxazole. Olsalazine, mesalazine and sulfasalazine may inhibit TPMT enzyme, resulting in an increased toxicity.
