Protonix and Nodal arrhythmia - a phase IV clinical study of FDA data

Summary:

Nodal arrhythmia is reported as a side effect among people who take Protonix (pantoprazole sodium), especially for people who are female, 60+ old, also take Digoxin, and have Atrial fibrillation/flutter.

The phase IV clinical study analyzes which people have Nodal arrhythmia when taking Protonix. It is created by eHealthMe based on reports of 130,073 people who have side effects when taking Protonix from the FDA, and is updated regularly.
