Patient Medication Information: uses, side effects, how to take - Pepcid Complete

What is PEPCID® COMPLETE® used for?

  • Begins to work on contact to provide fast, long lasting and effective relief from heartburn, acid indigestion and upset or sour stomach due to excess stomach acid.
  • Prevents these symptoms brought on by consuming food and/or beverage.

How does PEPCID® COMPLETE® work?

PEPCID® COMPLETE® contains the active ingredient famotidine (an acid reducer) along with the antacids, calcium carbonate and magnesium hydroxide. This advanced formula combines the benefits of both an antacid and acid reducer in one tablet.

PEPCID® COMPLETE® combines these two types of ingredients because they relieve heartburn in two different ways. The antacid begins by neutralizing acid on contact. The acid reducer keeps working, day or night, to reduce the production of excess stomach acid.
