Before taking Mesalamine

You should not use mesalamine if you are allergic to mesalamine, aspirin, sulfasalazine, or salicylates (such as Disalcid, Doans Pills, Dolobid, Kaopectate, Nuprin Backache, Pepto-Bismol, Tricosal, Trilisate, and others).

Some forms of mesalamine contain phenylalanine. Tell your doctor if you have phenylketonuria (PKU).

Tell your doctor if you are pregnant or plan to become pregnant. It is not known whether mesalamine will harm an unborn baby. However, having untreated or uncontrolled ulcerative colitis during pregnancy may cause complications such as low birth weight or premature birth. The benefit of treating ulcerative colitis may outweigh any risks to the baby.

It may not be safe to breastfeed while using this medicine. Ask your doctor about any risk. If you are breastfeeding, tell your doctor if you notice diarrhea in the nursing baby.

Do not give this medicine to a child without medical advice. Some brands of mesalamine are not approved for use in anyone younger than 18 years old. Delzicol should not be given to a child younger than 5 years old.
