Epipen and Injection site haematoma - a phase IV clinical study of FDA data
Summary:
Injection site haematoma is found among people who take Epipen, especially for people who are female, 40-49 old, have been taking the drug for < 1 month.
The phase IV clinical study analyzes which people take Epipen and have Injection site haematoma. It is created by eHealthMe based on reports of 20,390 people who have side effects when taking Epipen 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.
20,390 people reported to have side effects when taking Epipen.
Among them, 84 people (0.41%) have Injection site haematoma.
