Procysbi and Irritable bowel syndrome - a phase IV clinical study of FDA data


Irritable bowel syndrome is reported only by a few people who take Procysbi.

The phase IV clinical study analyzes which people take Procysbi and have Irritable bowel syndrome. It is created by eHealthMe based on reports of 880 people who have side effects while taking Procysbi from the FDA, and is updated regularly.

Phase IV trials are used to detect adverse drug outcomes and monitor drug effectiveness in the real world. With medical big data and AI algorithms, eHealthMe is running millions of phase IV trials and makes the results available to the public. Our original studies have been referenced on 600+ medical publications including The Lancet, Mayo Clinic Proceedings, and Nature.
