We are Certified



Prescription-strength famotidine is indicated for the treatment of stomach and small intestine ulcers, as well as gastroesophageal reflux disease (GERD), a condition in which the backwards flow of stomach acid causes heartburn and damage to the esophagus. It is also used for conditions that involve overproduction of stomach acid, such as Zollinger-Ellison syndrome.

Over-the-counter famotidine is utilized to prevent and relieve symptoms of heartburn and acid indigestion, caused by the consumption of certain foods or beverages. Famotidine is categorized as an H2 blocker and functions by reducing the amount of acid produced in the stomach.

Uses and Dosage

When taking prescription famotidine, follow the instructions provided by your doctor or pharmacist. The medication is available as a tablet or liquid suspension and should be taken either once daily at bedtime or two to four times a day.

For over-the-counter famotidine, it comes in different forms such as a tablet, chewable tablet, or capsule, and should be taken once or twice a day, 15 to 60 minutes before consuming foods or drinks that may cause heartburn. Do not exceed the recommended daily dose of two tablets or chewable tablets within a 24-hour period and avoid taking it for more than 2 weeks without a doctor’s recommendation.

When taking the liquid form, shake the bottle well for 5 to 10 seconds before each use to ensure the medicine is evenly mixed. The tablets and capsules should be taken with a full glass of water, and the chewable tablets should be thoroughly chewed before swallowing. If you experience symptoms of heartburn, acid indigestion, or sour stomach that persist for more than 2 weeks, you should discontinue use and consult your doctor.
