Zantac (generic name: ranitidine) is a medication that belongs to a class of drugs known as H2 blockers. It is primarily used to reduce the production of stomach acid and to treat conditions such as gastroesophageal reflux disease (GERD), ulcers, and heartburn. Zantac works by blocking histamine receptors in the stomach, which helps to decrease the amount of acid produced.
Zantac is available in various forms, including tablets, capsules, and oral solutions. It can be taken with or without food, and the dosage may vary depending on the specific condition being treated.
Zantac should not be taken if you are allergic to ranitidine or any other ingredients in the medication. It is important to inform your healthcare provider about any known allergies before starting Zantac.
Patients with a history of acute porphyria, a rare metabolic disorder, should also avoid taking Zantac.
Furthermore, it is important to consult your doctor if you have any of the following conditions:
- Impaired kidney or liver function
- A history of gastrointestinal bleeding
- Any other medical conditions or concerns
