Darvon-n side effects by duration, gender and age - a phase IV clinical study of FDA data
Summary:
Side effects are reported by people who take Darvon-n. Common side effects include drug hypersensitivity among females, and amnesia among males.
The phase IV clinical study is created by eHealthMe based on 83 reports 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 700+ medical publications including The Lancet, Mayo Clinic Proceedings, and Nature.
83 people who take Darvon-N and have side effects are studied.
