Cilostazol and Kidney infection (pyelonephritis) - a phase IV clinical study of FDA data


We study 7,434 people who have side effects when taking Cilostazol. Kidney infection (pyelonephritis) is found, especially among people who are male, 60+ old, have been taking the drug for 1 - 6 months, also take Nexium and have Diabetes.

The phase IV clinical study analyzes which people take Cilostazol and have Kidney infection (pyelonephritis). It is created by eHealthMe based on reports from the FDA, and is updated regularly. You may use the study as a second opinion to make health care decisions.

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 700+ medical publications including The Lancet, Mayo Clinic Proceedings, and Nature.
