👩🏽⚕️ Additional questions (FAQs)
💬 What disease are Mesalamine (Mesalamine / Asacol, Lialda) tablets used for?
This is one of the most effective (5-Aminosalicylic acid / 5-ASA) drugs in the world that can treat unbearable stomach pain, bloody diarrhea, and severe ulcers in the intestines (Ulcerative Colitis)! It instantly relieves severe inflammation and brings the patient back to normal.
💬 How do these pills (Mesalamine) treat severe intestinal ulcers/discomfort?
Intestinal ulcers/inflammation are caused by chemicals called 'Prostaglandins/Leukotrienes' that are produced in the intestine. The specialty of this pill is that it is not absorbed by the body even after it enters the stomach, it is broken down directly in the large intestine (colon) (Topical action). When it enters the intestine, it completely blocks/closes all the chemical factories (COX/LOX) that create ulcers. Then the swelling and bleeding stop right there.
💬 What are the dangers to be aware of when taking this intestinal medicine (Mesalamine)?
This is quite safe, but some people may experience 'Mesalamine-induced Acute Intolerance Syndrome', which can cause stomach cramps, bleeding, and severe diarrhea! If you experience any of these symptoms, you should stop taking the medicine immediately. Also, since it is made from aspirin/salicylate, people who are allergic to aspirin should not take this medicine!
