You can take two Pepcid AC 10mg tablets to equal a total dose of 20mg of the active ingredient famotidine. That is safe. 

However, according the Pepcid manufacturer website, all strengths of Pepcid AC are not chewable tablets, but are rather swallowed whole. The labeling for the products specifically state to swallow Pepcid AC tablets whole.

If you are referring to whether or not you can take Pepcid AC 10mg with Pepcid Complete (a chewable tablet), which contains 10mg of famotidine, that is fine as well. Pepcid complete simply contains famotidine 10mg and fast acting antacids (Calcium carbonate 800 mg, Magnesium hydroxide 165 mg) so the product will provide both immediate and longer lasting relief.

The important thing is to not go over the maximum daily dose of famotidine, which is 40mg.

About Pepcid (Famotidine)

Pepcid (famotidine) is an histamine type 2-receptor antagonist (i.e. H2 blocker) used in the treatment of gastrointestinal disorders such as gastroesophageal reflux disease (GERD) and heartburn. It works by blocking the binding of histamine to H2-receptors in the stomach which lowers the amount of acid your stomach produces and also decreases the gastric acid response to stimuli such as food and caffeine. Pepcid can be taken with or without food, but has the best effects if taken 15 to 60 minutes before food. While H2 blockers like Pepcid aren't as effective as reducing stomach acid in the long term as PPI medications are (e.g. Prilosec), they provide more immediate relief, working in as few as 15 minutes.
