Good to know
- Pepcid AC Original Strength is famotidine 10 mg — half the dose of Maximum Strength, so it is not in this group.
- Pepcid Complete and store-brand "Dual Action" chewables combine famotidine 10 mg with calcium carbonate and magnesium hydroxide — a different product.
- Kirkland Signature Acid Controller is famotidine 20 mg, the same active ingredient and strength as Pepcid AC Maximum Strength.
