How does OTC famotidine work?
Famotidine is a histamine H2 blocker. It works by reducing the amount of acid produced in the stomach [1]. This action helps to relieve symptoms of heartburn and prevent their recurrence [1].

Famotidine generally starts to work within 15 to 30 minutes after taking it [1]. The full effect may take longer, and it is effective for up to 12 hours [1].
What is famotidine used for?
Over-the-counter famotidine is indicated for the prevention and relief of heartburn [1]. It can be taken to prevent heartburn when symptoms are anticipated or to treat heartburn once it occurs [1]. Prescription strengths are used for conditions like peptic ulcers, gastroesophageal reflux disease (GERD), and Zollinger-Ellison syndrome [2].
How long can I take OTC famotidine?
OTC famotidine is intended for short-term use, typically for up to 14 days [1]. If heartburn continues or recurs frequently, it is recommended to consult a healthcare professional to rule out more serious conditions [1].
What are the potential side effects of famotidine?
Common side effects of famotidine are generally mild and may include headache, dizziness, or constipation [3]. Serious side effects are rare but can occur [3]. Patients should seek medical attention if they experience symptoms such as difficulty breathing, swelling, or severe allergic reactions [3].
Are there any drug interactions with famotidine?
Famotidine can interact with certain medications, including those that require an acidic environment for absorption, such as ketoconazole and itraconazole [3]. It may also affect the absorption of other drugs. It is important to inform a healthcare provider about all medications, including supplements and herbal products, being taken [3].

Famotidine 20mg is available without a prescription at most pharmacies and retailers [1]. Brands like Pepcid AC are common examples [1].
What is the difference between famotidine and other heartburn medications?
