Doxycycline and Salmonella enterocolitis - a phase IV clinical study of FDA data


Salmonella enterocolitis is found among people who take Doxycycline, especially for people who are female, 30-39 old.

The phase IV clinical study analyzes which people take Doxycycline and have Salmonella enterocolitis. It is created by eHealthMe based on reports of 53,763 people who have side effects when taking Doxycycline 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.
