Pyridium and Pataday drug interactions - a phase IV clinical study of FDA data
Summary:
Drug interactions are reported only by a few people who take Pyridium and Pataday together.
The phase IV clinical study analyzes what interactions people who take Pyridium and Pataday have. It is created by eHealthMe based on reports of 5 people who take the same drugs 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.
5 people who take Pyridium and Pataday together, and have interactions are studied.
