DRUG INTERACTIONS: Oral mesalamine formulations are associated with several drug interactions. Combining mesalamine with drugs that affect kidney function, for example, nonsteroidal antiinflammatory drugs (NSAIDs) or ibuprofen may increase the likelihood of reduced function of the kidneys. Concurrent use of mesalamine and 6-mercaptopurine or azathioprine (Imuran) may increase the likelihood of disorders of the blood cells, particularly reduced numbers of cells. Mesalamine may increase the blood thinning effect of warfarin (Coumadin).
PREGNANCY: There are no adequate human studies of mesalamine during pregnancy. Mesalamine is known to cross the placenta into the fetus, but animal studies revealed no evidence of harm to the fetus. Mesalamine should only be used during pregnancy if it is felt that the benefit of its use justifies the unknown risks.
NURSING MOTHERS: Mesalamine is excreted in breast milk. Mesalamine should only be used by nursing mothers if it is felt that the benefit of its use justifies the potential but unknown risk to the infant.
