Purinol Allopurinol Cyclosporine
ModerateThe text supplied for this pair does not mention allopurinol. It lists other medicines that lower or raise cyclosporine levels, and the list stops partway through, before it reaches any statement about allopurinol. Because nothing in it says what happens when cyclosporine and allopurinol are taken together, there is no interaction effect here that I can write up without making one up.
These medicines are often taken together with some care. Your doctor may change a dose, space them apart or check on you more often. Make sure your doctor and pharmacist know you take both.
