Ceftriaxone and Fentanyl-100 drug interactions - a phase IV clinical study of FDA data


Drug interactions are reported among people who take Ceftriaxone and Fentanyl-100. Common interactions include osteoarthritis among females and gastrointestinal haemorrhage among males.

The phase IV clinical study analyzes what interactions people who take Ceftriaxone and Fentanyl-100 have. It is created by eHealthMe based on reports of 26 people who take Ceftriaxone and Fentanyl-100 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.
