This Is What Pepcid Does For Your Body

GoodRx states that Pepcid, also known by its generic name famotidine or the brand name Zantac, is a medication used to treat stomach or intestinal ulcers. It can also be used to relieve heartburn, gastroesophageal reflux disease (GERD), erosive esophagitis due to GERD, and other conditions associated with too much stomach acid.

The American Academy of Family Physicians explains that ulcers are sores in the stomach and intestine. They can cause pain or discomfort during meals or at night, bloating, and a quick feeling of fullness when eating. These sores may also bleed if they become torn. Most ulcers are caused by a type of bacteria called Heliocobacter pylori (H. pylori). Long-term use of certain drugs like aspirin or ibuprofen can also make a person more susceptible to ulcers.

Heartburn and GERD occur when a weak valve between the esophagus and stomach allows stomach contents to enter the esophagus, causing burning and pain, according to the Cleveland Clinic. 

The stomach acid that is produced when we eat contributes to the discomfort associated with conditions like GERD. While the stomach is normally protected by a layer of mucus, if this barrier is compromised, it can cause burning and pain, says Scientific American. Problems can also arise when stomach acid reaches areas outside the stomach, notes Cleveland Clinic.

Pepcid is a medication that belongs to a class of drugs called H2 antagonists. These drugs block histamine from triggering the secretion of acid in the stomach, according to Drugs.com. This allows them to combat excess stomach acid.

The American Academy of Family Physicians writes that drugs like Pepcid may be prescribed along with antibiotics to help battle an H. pylori infection. Pepcid helps reduce stomach acid production, reducing pain and allowing the stomach lining to heal. It can also help treat the symptoms of heartburn and GERD.
