STORAGE: Store at room temperature, 15-25 C (59-77 F)
PRESCRIBED FOR: Lialda is used for inducing remission in patients with active, mild to moderate ulcerative colitis. In clinical studies which compared mesalamine against placebo for 8 weeks, more patients in the mesalamine group achieved remission.
DOSING: The recommended dose is 2.4 g or 4.8 g once daily with a meal. Tablets should be swallowed whole without breaking the coating.
DRUG INTERACTIONS: Specific drug interaction studies have not been conducted with Lialda. Other mesalamine medications have been associated with several drug interactions. Combining mesalamine with drugs that affect kidney function, for example, nonsteroidal antiinflammatory drugs (for example, ibuprofen), may increase the likelihood of kidney dysfunction. Concurrent use of mesalamine and 6-mercaptopurine or azathioprine (Imuran) may increase the likelihood of blood disorders. Mesalamine may increase the blood thinning effect of warfarin (Warfarin).
PREGNANCY: There are no adequate human studies of mesalamine use 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 risk.
SIDE EFFECTS: The most common side effects are headache and flatulence. Hair loss and itching also may occur. Infrequent side effects include increased heart rate, acne, pancreatitis, back pain, fatigue, tremor, ear pain, and blood disorders. Kidney dysfunction has been associated with mesalamine. Kidney function should be evaluated prior to and periodically during mesalamine therapy. Mesalamine may cause an acute intolerance syndrome that resembles a flare of inflammatory bowel disease. Symptoms include cramping, acute abdominal pain, and bloody diarrhea. Fever, headache, itching, and rash also may occur. Symptoms usually subside once mesalamine is discontinued. Since mesalamine is related chemically to aspirin, individuals who are allergic to aspirin should not take mesalamine.
