Can We Use Famotidine For Allergies?

Although hives, a scratchy throat, and constant sneezing are common allergy symptoms, many things could trigger them. From dust and pollen in the air to medications, you’ll never know what causes your body’s reactions until it happens.

Though many people in the US deal with allergies daily, there is no cure—just treatments to help ease symptoms. Luckily for these sufferers of sneezing and throat tightening, medications such as generic loratadine and cetirizine are used. Still, limited research suggests that Famotidine can also provide additional relief from your allergy troubles.

What is Famotidine?

Famotidine is a medication that decreases stomach acid production and is widely used in peptic acid disease. It is typically used to treat peptic ulcers, gastroesophageal reflux disease, and Zollinger-Ellison syndrome. Famotidine belongs to a group of antihistamines (H2) that works by decreasing the amount of acid the stomach produces. Famotidine also treats gastroesophageal reflux disease (GERD) and other conditions in which acid backs up from the stomach into the esophagus, causing heartburn.

Can it be used for allergies?

The antihistamines like H1 receptor blockers are used primarily to treat allergic reactions, including urticaria, rhinitis, dermatitis, itching, etc. However, recent studies have shown that histamine H2-receptor blockers like Famotidine may also help treat urticaria. In addition, some studies suggest that a combination of H1 and H2 blockers can help treat urticaria when the H1 blockers alone don’t work.

While for GERD, you will need to take 20mg twice daily for six weeks. It is mainly used at night to reduce gastric acidity during the night and morning time.
