Description
Indications
Mesalamine is employed in the treatment of ulcerative colitis, a condition characterized by inflammation and sores in the lining of the colon (large intestine) and rectum. Additionally, it is used to sustain the improvement of symptoms associated with ulcerative colitis. Mesalamine belongs to a class of medications known as anti-inflammatory agents. Its mechanism of action involves inhibiting the body’s production of a specific substance that has the potential to induce inflammation.
Uses and Dosage
Take this medication orally, with or without food, as instructed by your doctor, usually three times a day. For some brands, it is recommended to take them on an empty stomach, either at least 1 hour before or 2 hours after a meal. Consult your doctor or pharmacist for specific instructions related to your particular brand.
Swallow the medication whole; do not crush, chew, or break it. Doing so could hinder the proper release of the drug into the colon.
Ensure you stay well-hydrated during the course of this medication unless otherwise directed by your doctor. Adequate fluid intake can help prevent the formation of kidney stones.
The dosage is determined by your medical condition and response to treatment. In children, the dosage may also be based on weight. Different brands may deliver varying amounts of medication. Do not switch brands without your doctor’s approval and specific instructions.
Consistently use this medication to maximize its benefits. To aid in remembering, take it at the same times each day.
