Mesacol 800 is indicated for treating moderately active ulcerative colitis in adults. Each delayed-release tablet for oral administration contains 400 mg of Mesalamine, an anti-inflammatory agent. Mesalamine belongs to a class of drugs known as aminosalicylates, which work by decreasing swelling in the colon. Mesalamine is considered the major therapeutically active part of the sulfasalazine molecule in treating ulcerative colitis. It helps relieve stomach pain, diarrhoea and bleeding by reducing bowel inflammation. The safety and efficacy of Mesacol tablets beyond six weeks have not been established.

Take Mesacol delayed-release tablet by mouth with a meal as directed by your doctor, usually once daily. Swallow the medicine whole with a glass full of water. Do not chew or crush the tablet. This can keep the medicine from being released properly into the colon. Drink plenty of water while receiving Mesalamine tablets unless directed by your doctor. This helps to prevent kidney stones. The dosage is usually based on the medical condition and treatment response. For children, the dosage is based on weight. Take medicine regularly to get the most benefit from it. To help you remember, take it at the same time every day. Let your doctor know if your condition does not improve or if it worsens.

Mesacol 800 mg should not be used in patients with hypersensitivity to salicylates or any of the components of the medicine.  

The safety and effectiveness of mesalamine in pediatric patients have not been established. See your doctor for other alternatives for use in children.  

Before taking Mesalamine, tell your doctor if you have any liver or kidney problems or a blockage in your stomach. Your age may also be a deciding factor in whether this drug is suitable. Pregnant or breastfeeding women should consult their doctor before taking this medicine. Inform your doctor about all the medications you are taking, as some may affect or be affected by this medicine. Before having surgery, let your doctor know about all the products you are using, including prescription drugs and non-prescription items (vitamins and herbal supplements).

The most common side effects of using Mesacol 800 are stomach pain, diarrhoea, headache, flatulence, dizziness, vomiting, joint pain, dizziness, itching, and muscle pain. Let your doctor know if any of these symptoms bother you, do not resolve, or worsen. There may be ways to reduce or prevent them. Some people may get a severe allergic reaction that needs immediate medical attention. Talk to your doctor immediately if you notice symptoms like rash, sore throat, fever, swelling of the lips, throat, or tongue, unusual bleeding or excessive tiredness.
