Megestrol acetate and Retching - a phase IV clinical study of FDA data


Retching is found among people who take Megestrol acetate, especially for people who are female, 60+ old, have been taking the drug for < 1 month.

The phase IV clinical study analyzes which people take Megestrol acetate and have Retching. It is created by eHealthMe based on reports of 4,472 people who have side effects when taking Megestrol acetate from the FDA, and is updated regularly. You can use the study as a second opinion to make health care decisions.

With medical big data and AI algorithms, eHealthMe enables everyone to run phase IV clinical trial to detect adverse drug outcomes and monitor effectiveness. Our original studies have been referenced on 600+ peer-reviewed medical publications including The Lancet, Mayo Clinic Proceedings, and Nature. Most recently, phase IV clinial trails for COVID 19 vaccines have been added, check here.
