Hydroxychloroquine sulfate and Halo vision - a phase IV clinical study of FDA data


Halo vision is reported only by a few people who take Hydroxychloroquine Sulfate.

The phase IV clinical study analyzes which people take Hydroxychloroquine sulfate and have Halo vision. It is created by eHealthMe based on reports of 32,423 people who have side effects while taking Hydroxychloroquine sulfate from the FDA, and is updated regularly.

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.
