Rocaltrol and Ventricular tachycardia - a phase IV clinical study of FDA data

Summary:

Ventricular tachycardia is reported as a side effect among people who take Rocaltrol (calcitriol), especially for people who are male, 50-59 old, also take Allopurinol, and have Hyperphosphataemia.

The phase IV clinical study analyzes which people have Ventricular tachycardia when taking Rocaltrol. It is created by eHealthMe based on reports of 7,521 people who have side effects when taking Rocaltrol from the FDA, and is updated regularly.

What is Rocaltrol?

Rocaltrol has active ingredients of calcitriol. It is often used in hypoparathyroidism. eHealthMe is studying from 7,562 Rocaltrol users. Check the latest studies of Rocaltrol.
