Famotidine

Indications: Famotidine is used to treat conditions such as gastroesophageal reflux disease (GERD), peptic ulcers, and conditions where excessive stomach acid is produced, including Zollinger-Ellison syndrome.

Mechanism of Action: Famotidine works by blocking the action of histamine on histamine H2 receptors in the stomach. This reduces the production of stomach acid, helping to relieve symptoms associated with conditions caused by excess acid.

Dosage Forms: Famotidine is available in various forms, including tablets, oral suspension, and injectable formulations. Over-the-counter versions are typically available in lower strengths compared to prescription-strength versions.

Dosage and Administration: The dosage of famotidine will depend on the specific condition being treated and the individual's response to the medication. It is usually taken orally, with or without food, as directed by a healthcare provider.

Duration of Treatment: The duration of treatment with famotidine can vary. It may be prescribed for short-term relief of symptoms or for longer periods, depending on the underlying condition.

Side Effects: Common side effects of famotidine may include headache, dizziness, constipation, and diarrhea. Serious side effects are rare but can include severe allergic reactions.

Interactions: Famotidine can interact with certain medications, and it's important to inform a healthcare provider about all medications, including over-the-counter drugs and supplements, being taken.

Caution: Individuals with certain medical conditions, such as kidney problems, may require dosage adjustments or special monitoring when using famotidine. It's important to discuss any existing health conditions with a healthcare provider.

Over-the-Counter Use: Lower-strength famotidine is available without a prescription for the short-term relief of heartburn associated with acid indigestion and sour stomach. Over-the-counter use is typically for a duration of up to 14 days.
