		Factor Name		Immunosuppressive effects
		Factor Description		Immunosuppression is when your immune system is not functioning as it should. The immune system is made up of cells, tissues and organs that help the body fight off infections. If the immune system is suppressed, an infection that your body was able to control may become serious or even fatal.
Mechanism Description		Additive immunosuppressive effects by the combination of Levamisole and Azathioprine

Recommended Action
Management		Concomitant use of azathioprine with other immunosuppressive or myelosuppressive agents should be avoided whenever possible. Close clinical and laboratory monitoring for hematologic toxicity is advised if coadministration is required. Since azathioprine is considered a slow-acting drug, delayed myelosuppression may occur, and effects may persist even after the drug has been discontinued. Prompt reduction in dosage or temporary withdrawal of azathioprine may be necessary if a persistently low or rapid decline in leucocyte count occurs, or if there is other evidence of bone marrow depression.
