Pet Medication 101: Zantac

1. Drug Name:

ranitidine

2. Brand Name:

Zantac

3. How Dispensed:

On April 1, 2020, the FDA requested the removal of all ranitidine products from the market (over-the-counter and prescription) immediately due to a contaminant known as NDMA, a probable human carcinogen.

Histamine-2 blocker
