Cimetidine belongs to a class of drugs known as H2 blockers and is utilized in the treatment of several conditions such as ulcers, gastroesophageal reflux disease (GERD), and Zollinger-Ellison syndrome. Over-the-counter cimetidine can be used to prevent and relieve symptoms of heartburn associated with acid indigestion and sour stomach by reducing the production of acid in the stomach.

Uses and Dosage

To ensure maximum benefit from this medication, take it orally as directed by your healthcare provider, with or without food. Your doctor will determine the appropriate dosage and duration of treatment based on your medical condition and response to therapy.

If your doctor has recommended antacids for stomach pain relief, take them at least an hour apart from this medication.

Take this medication regularly as prescribed, ideally at the same time(s) every day, to help you remember. Do not exceed the recommended dosage or frequency of administration.

Even if your symptoms improve, continue taking this medication for the prescribed duration of treatment. Discontinuing treatment prematurely may delay the healing process.

For self-treatment of acid indigestion or heartburn with over-the-counter cimetidine, take one tablet orally with a glass of water as required. To prevent heartburn, take one tablet orally with a glass of water immediately before or up to 30 minutes before consuming foods or drinks that trigger heartburn. Do not take more than two tablets within a 24-hour period, unless directed otherwise by your physician. Do not take for more than 14 consecutive days without consulting your doctor.

Inform your physician if your symptoms persist or worsen.
