What Drugs Interact With Relafen?

Relafen may interact with antidepressants, blood thinners, lithium, methotrexate, diuretics (water pills), steroids, aspirin or other NSAIDs, or ACE inhibitors.. There are no adequate, well-controlled studies in pregnant women, and Relafen should be used in pregnancy only if the potential benefit justifies the potential risk to the fetus. Use during late pregnancy should be avoided because of the known effects of NSAIDs in the fetal cardiovascular system (closure of ductus arteriosus). It is not known whether Relafen is excreted in human milk; a decision should be made whether to discontinue breastfeeding or to discontinue the Relafen.
