Amoxicillin and Atrioventricular block first degree - a phase IV clinical study of FDA data

Summary:

Atrioventricular block first degree is reported as a side effect among people who take Amoxicillin (amoxicillin), especially for people who are male, 50-59 old, also take Digoxin, and have Atrial fibrillation/flutter.

The phase IV clinical study analyzes which people have Atrioventricular block first degree when taking Amoxicillin. It is created by eHealthMe based on reports of 95,831 people who have side effects when taking Amoxicillin from the FDA, and is updated regularly.
