Understanding Acid Reflux and the Role of H2 Receptor Antagonists Acid reflux, also known as gastroesophageal reflux disease (GERD), occurs when stomach acid flows back into the esophagus, causing symptoms like heartburn, regurgitation, and discomfort in the chest. For many, H2 receptor antagonists (also called H2 blockers) offer fast, effective relief by reducing the amount of acid the stomach produces. These medications are available over the counter and by prescription and are often recommended by pharmacists for their quick action and reliable relief.
If you’re looking for the best options available today, here’s our pharmacist-recommended list of the top 5 H2 receptor antagonists, reviewed with pros and cons to help guide your decision.
1. Pepcid AC (Famotidine)
Most Recommended by Pharmacists
Why It’s #1: Famotidine, the active ingredient in Pepcid AC, is widely regarded for its potency and fewer drug interactions compared to other H2 blockers. It provides long-lasting relief and is effective in both treating and preventing acid reflux symptoms.

- Fast-acting, often within an hour
- Lasts up to 12 hours
- Fewer side effects than older H2 blockers
- Safe for long-term use in most cases

Cons:
- Withdrawn due to potential NDMA contamination
