Prednisone and Obstruction - a phase IV clinical study of FDA data
Summary:
Obstruction is found among people who take Prednisone, especially for people who are male, 60+ old, have been taking the drug for < 1 month.
The phase IV clinical study analyzes which people take Prednisone and have Obstruction. It is created by eHealthMe based on reports of 523,651 people who have side effects when taking Prednisone from the FDA, and is updated regularly. You can 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 600+ medical publications including The Lancet, Mayo Clinic Proceedings, and Nature.
523,651 people reported to have side effects when taking Prednisone.
Among them, 527 people (0.1%) have Obstruction.
