Lialda is FDA-approved for the induction and maintenance of remission in patients with mild to moderate ulcerative colitis. It may also be used off-label for other inflammatory conditions affecting the colon.
Lialda contains mesalamine (5-aminosalicylic acid), which works locally in the colon to reduce inflammation. It inhibits inflammatory mediators and free radicals in the intestinal lining, helping to control symptoms such as rectal bleeding, diarrhea, and abdominal pain associated with ulcerative colitis.
Lialda is typically taken once daily with a meal. Patients with known kidney problems, stomach obstruction, or allergies to salicylates should use caution. Common side effects may include headache, nausea, and abdominal pain. Rare but serious side effects can include pancreatitis, hepatitis, and worsening of colitis. Regular monitoring by a healthcare provider is recommended during treatment.
