Azathioprine is a medication prescribed to prevent organ rejection in individuals who have undergone kidney transplant surgery. It is typically used in combination with other drugs to facilitate normal kidney function. Azathioprine is also utilized in the treatment of rheumatoid arthritis, a condition where the body’s immune system attacks healthy joints.

Azathioprine belongs to the immunosuppressant class of drugs, which function by weakening the immune system. This mechanism helps the body to accept the new kidney as if it were native to the body, in the case of an organ transplant. In rheumatoid arthritis patients, azathioprine is employed to prevent further joint damage.

Uses and Dosage

Azathioprine is administered orally in the form of tablets. It is typically taken once or twice daily after meals.

Consistency is key when taking azathioprine, so it is advisable to take it at the same time every day. Follow the instructions on your prescription label carefully. Take azathioprine exactly as directed, without taking more or less than the prescribed dosage or increasing the frequency.

If you are using azathioprine to treat rheumatoid arthritis, your doctor may initiate treatment with a low dose and increase it gradually after 6-8 weeks, but not more than once every 4 weeks. When your condition is under control, your doctor may gradually reduce your dosage.

For preventing kidney transplant rejection, your doctor may prescribe a higher dose at the start, which can then be gradually decreased as your body adapts to the transplant.

While azathioprine is effective in managing rheumatoid arthritis, it does not cure the condition. It may take up to 12 weeks before experiencing the full benefits of azathioprine.

Azathioprine only prevents transplant rejection as long as it is taken. Continue taking this medication even when feeling well. Discontinuing azathioprine without consulting your doctor is not recommended.
