Brain midline shift and drugs of ingredients of nifedipine - a phase IV clinical study of FDA data


Brain midline shift is found among people who take drugs with ingredients of nifedipine, especially for people who are female, 60+ old , have been taking the drugs for < 1 month. This phase IV clinical study is created by eHealthMe based on reports of 79,982 people who have side effects when taking drugs with ingredients of nifedipine from the FDA, and is updated regularly.

Drug(s) considered in the study (i.e. both brand name and generic drugs): Adalat, Adalat cc, Afeditab cr, Nifedipine, Procardia, Procardia xl.

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.
