Are there withdrawl symtoms associated to Imuran?

Hi, there must be a connection between his inmune system and the fever he has developed.

CONTACT HIS DOCTOR ASAP

Brand Names: Azasan, Imuran
Generic Name: azathioprine

Immune system disorders

Uncommon: hypersensitivity reactions
Several different clinical syndromes, which appear to be idiosyncratic manifestations of hypersensitivity, have been described occasionally following administration of IMURAN. Clinical features include general malaise, dizziness, nausea, vomiting, diarrhoea, FEVER, rigors, exanthema, rash, vasculitis, myalgia, arthralgia, hypotension, renal dysfunction, hepatic dysfunction and cholestasis

WARNING: Long-term use of azathioprine may increase your risk of developing certain types of cancer (e.g., skin cancer, lymphoma). You must be closely monitored by your doctor during treatment and regularly afterwards if your doctor stops treatment with this medication. Azathioprine may also cause serious (rarely fatal) blood disorders (decreased bone marrow function leading to anemia, low number of white blood cells and platelets). It can lower your body's ability to fight an infection. The risk of these side effects is higher in patients receiving this medication to prevent kidney transplant rejection than in patients treated for rheumatoid arthritis. To reduce the risk of side effects, use this medication at the lowest effective dose. Keep all medical and laboratory appointments.
