Famotidine is a medication used to reduce stomach acid. It is available in both preservative-containing and preservative-free formulations [1].
Why is preservative-free famotidine used?
Preservative-free formulations of famotidine are often preferred for individuals who may be sensitive to preservatives or for specific administration routes. Preservatives can sometimes cause local irritation or allergic reactions in sensitive individuals [2].
What forms does preservative-free famotidine come in?
Preservative-free famotidine is typically available as an oral suspension [1].
Who might need preservative-free famotidine?
Patients with certain allergies or sensitivities may benefit from preservative-free famotidine. Additionally, healthcare providers may recommend it for specific patient populations where preservative use is a concern [2].
How does famotidine work to reduce stomach acid?
Famotidine is a histamine H2-receptor antagonist. It works by blocking the action of histamine on parietal cells in the stomach, which are responsible for producing acid [3]. This action leads to a significant decrease in both the volume and acidity of stomach secretions [3].
What conditions is famotidine prescribed for?
Famotidine is commonly prescribed for conditions such as peptic ulcers (gastric and duodenal), Zollinger-Ellison syndrome, and gastroesophageal reflux disease (GERD) [3]. It helps to relieve symptoms like heartburn and indigestion by reducing excess stomach acid [3].
