Uses of Zantac and How to Take It

Zantac, also referred to by its generic name ranitidine, is a histamine H2-receptor antagonist drug class member. It is frequently used to treat and prevent diseases like gastroesophageal reflux disease (GERD), peptic ulcers, and heartburn linked to too much stomach acid production. Zantac reduces the amount of acid produced in the stomach and relieves symptoms like acid reflux and indigestion by inhibiting histamine receptors in the gut. Zantac has been used extensively for years, but safety concerns arose when residues of a possible carcinogen were discovered in several formulations, causing recalls and withdrawals in several regions. Doctors now use alternative drugs to treat diseases linked to acidity.

Zantac comes in the following forms: tablets, capsules, liquid-filled capsules, syrup, powder to mix with liquid, and liquid for oral suspension. These are all meant to be consumed orally.
Although most places sell ranitidine over the counter, if your doctor thinks you require a more significant dose, they might prescribe Zantac.
Always abide by the dosage and usage guidelines in the box or the directions provided with your prescription. Ranitidine may occasionally be administered intravenously through IV or injection. This wouldn’t be provided in this form for prescription use at home; instead, it would only be administered by a qualified healthcare professional at an accredited healthcare facility.

Important Information About Zantac

Following are some points that you should know about Zantac:

  • Zantac may interact with certain drugs, including blood thinners, anti-seizure medications, and antacids, affecting their effectiveness or causing adverse reactions.
  • Avoid using Zantac alongside other H2-blockers like famotidine or cimetidine, as it can lead to over-suppression of stomach acid and potential health issues.
  • Common side effects include headache, dizziness, and diarrhea. Rare but severe reactions may have allergic reactions, liver problems, and changes in heart rhythm.
  • Some formulations of Zantac contained low levels of N-nitroso dimethylamine (NDMA), a potential carcinogen, leading to recalls and discontinuation in certain regions.
  • Extended usage of Zantac may increase the risk of certain nutrient deficiencies and fractures, so it should be used under medical supervision.
