Delzicol is indicated for the treatment of mild to moderate ulcerative colitis in adults and pediatric patients weighing at least 55 pounds. It may be used to both induce remission and maintain long-term remission of the disease.
Delzicol contains mesalamine, which acts locally on the inflamed colonic mucosa. It works by inhibiting inflammatory mediators, suppressing inflammatory cell activity, and reducing the production of inflammatory cytokines in the colon.
Delzicol is contraindicated in patients with known hypersensitivity to salicylates or mesalamine. Patients should be monitored for worsening symptoms, kidney function, and blood disorders. The delayed-release capsules should be swallowed whole without crushing or chewing. Inform patients about potential side effects including headache, nausea, abdominal pain, and rarely, worsening colitis or acute intolerance syndrome.
