For millions of people, the burning discomfort of heartburn and the sour taste of acid reflux are unwelcome interruptions to daily life. Finding fast, effective, and reliable relief is a top priority. Among the most trusted over-the-counter solutions is Pepcid AC, a brand synonymous with heartburn relief. At its core is the active ingredient famotidine, a powerful acid reducer that works differently from traditional antacids to provide both relief and prevention.
How Pepcid AC and Famotidine Work
Unlike antacids that simply neutralize existing stomach acid, famotidine is an H2 blocker (histamine-2 blocker). It works by reducing the amount of acid your stomach produces. This dual-action approach means it can both relieve symptoms that have already started and help prevent heartburn before it occurs, especially when taken before eating known trigger foods. This makes Pepcid AC a versatile option for managing occasional acid indigestion and sour stomach.
Choosing the Right Strength: Maximum vs. Original
Pepcid AC is available in different formulations to suit individual needs. The Maximum Strength version contains 20mg of famotidine per tablet and is designed for more intense or frequent symptoms. Products like the AC Maximum Strength Heartburn Relief Tablets offer a robust 20mg dose for fast-acting relief. For a larger supply, options like the 75-count box or the pack of 2 boxes (150 tablets total) provide excellent value for regular users.
The Original Strength formula contains 10mg of famotidine and is a great choice for milder symptoms or for those new to acid reducers. The AC Original Strength Heartburn Relief Tablets (90 ct) or the convenient 30-count pack are perfect for keeping on hand.

Pepcid AC vs. Dual-Action Complete Chewable Antacids
While Pepcid AC is a dedicated acid reducer, another effective category is dual-action products that combine an acid reducer with an antacid. A prime example is Complete Chewable Antacid Tablets. These berry-flavored chews offer immediate relief from the antacid components (calcium carbonate and magnesium hydroxide) while the famotidine works to reduce future acid production. This can be ideal for getting relief the moment symptoms strike. For a direct comparison, our blog Pepcid AC vs. Complete Chewable Antacid breaks down the pros and cons of each approach.
Key Benefits and What to Expect
The primary benefit of using Pepcid AC is its fast-acting and long-lasting relief. Many users experience relief within 15 to 30 minutes, with effects that can last up to 12 hours. It's a non-prescription, OTC medicine that prevents and relieves heartburn due to acid indigestion. Whether you opt for the standalone acid reducer like Maximum Strength Famotidine Tablets 20 mg or a convenient travel pack like the 50 Count + 8 Count Travel Pack, you have a reliable tool for managing discomfort.
For those who prefer a chewable format that also neutralizes acid on contact, the Complete Acid Reducer + Antacid Chews offer a great alternative.

Using Pepcid AC Safely and Effectively
As with any OTC medication, it's important to use Pepcid AC as directed on the label. The standard dose for prevention is one tablet (10mg or 20mg depending on strength) 15 to 60 minutes before eating or drinking items that may cause heartburn. For relief of existing symptoms, take one tablet as needed. Do not exceed the recommended dosage within a 24-hour period. While generally well-tolerated, it's wise to be aware of potential side effects and consult a doctor if symptoms persist beyond two weeks.
