Generic Zantac
Used for Duodenal Ulcer, Gastric Ulcer, GERD, Heartburn

Ranitidine is an H2 blocker that reduces the amount of acid the stomach produces. It's used to treat conditions like gastroesophageal reflux disease (GERD) and ulcers. It was recalled in 2020 due to safety concerns about a chemical impurity, but it has since been reformulated and is now back on the market. Your dose depends on why you’re taking it, but it’s usually taken by mouth one to four times a day. Side effects include headache, dizziness, and feeling tired.

Pharmacist tips for Ranitidine

pharmacist
  • You can take ranitidine with or without food.
  • If ranitidine alone isn't providing you with enough heartburn relief, ask your prescriber about also taking an antacid for better relief.
  • Tell your prescriber if you have a history of porphyria because ranitidine can make the condition worse.
  • Ranitidine can interact with many medications, especially ones that need stomach acid to work well. Tell your care team about all of the medications you're taking. Don't start any new medications without talking to your care team first so they can help you check for interactions.
  • Store ranitidine tablets in its original bottle and protect them from moisture. Make sure to leave the desiccant in the bottle and close the bottle right after removing a tablet with dry fingers.
  • Open only one bottle of ranitidine at a time. Throw it away after 90 days or by the expiration date, whichever comes first.

Risks and warnings for Ranitidine

Ranitidine can cause some serious health issues. This risk may be even higher for certain groups. If this worries you, talk to your doctor or pharmacist about other options.

Risk of hiding symptoms of a more serious problem

Frequent episodes of heartburn can be a sign of stomach cancer. If your heartburn gets worse or comes back after taking ranitidine, let your prescriber know. Also contact them if you have a poor appetite, unexplained weight loss, or weakness along with heartburn, so they can check for other serious health problems.

Medication interactions

Ranitidine lowers the amount of acid in your stomach, which can change how some medications are absorbed and affect how they work. Examples include atazanavir, ketoconazole, glipizide, and triazolam.

Ranitidine also can interact with the blood thinner warfarin, so your prescriber might need to check your bloodwork more often. Always talk to your prescriber before taking ranitidine with other medications.

Allergic reactions

  • Risk factors: History of allergy to FD&C Yellow No. 5 (tartrazine)

Ranitidine tablets might contain a dye called FD&C Yellow No. 5 (tartrazine). Although rare, some people can have an allergic reaction to this ingredient. If you have hives, itching, or other signs of an allergic reaction, seek medical attention.
