Vitamin b12 and Cardiac flutter - a phase IV clinical study of FDA data
Summary:
Cardiac flutter is found among people who take Vitamin b12, especially for people who are female, 60+ old.
The phase IV clinical study analyzes which people take Vitamin b12 and have Cardiac flutter. It is created by eHealthMe based on reports of 97,738 people who have side effects when taking Vitamin b12 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.
97,738 people reported to have side effects when taking Vitamin b12.
Among them, 111 people (0.11%) have Cardiac flutter.
