Summary

  • Azathioprine is used to treat autoimmune diseases such as rheumatoid arthritis, lupus, and Crohn's disease. It's also used to prevent the body from rejecting a transplanted organ.

  • Azathioprine works by suppressing your immune system. It reduces the activity of certain immune cells, which can help to lessen inflammation and prevent damage to your body's tissues. The exact way it works is not fully understood, but it's thought to suppress the production of antibodies and other immune factors that can cause inflammation and damage.

  • Azathioprine is typically started at a small dose of 50 to 100 mg taken orally once or twice a day. If needed, your doctor may gradually increase the dose up to a maximum of 2.5 mg/kg per day.

  • Common side effects of Azathioprine include nausea, vomiting, skin rashes, hair loss, fever, joint pain, and diarrhea. More serious side effects can include a low white blood cell count, infections, and even cancer.

  • Azathioprine should not be used during pregnancy unless the benefits outweigh the risks. It's also not recommended for nursing mothers. If you're taking gout medications like allopurinol or febuxostat, your Azathioprine dose may need to be adjusted. Regular blood tests are needed while taking Azathioprine, and you should contact your doctor if you experience any signs of infection or unusual bleeding.

Concomitant use of azathioprine with febuxostat, another gout medication, is not recommended as it may increase the risk of side effects.

You can generally take Azathioprine with vitamins or supplements, but some, like folic acid, may interact with it. Always inform your doctor about any vitamins, minerals, or supplements you are taking to avoid potential interactions or side effects.
