Zantac (Ranitidine): What Happened and What to Use for Heartburn Instead

Zantac (ranitidine) has been withdrawn from markets in many countries since 2020 because of NDMA contamination, and it is no longer a suitable choice for treating heartburn. Common alternatives today are antacids for occasional symptoms, famotidine from the same drug family, and proton pump inhibitors for chronic reflux and ulcers. A doctor or pharmacist will determine the most suitable option for your condition and symptoms.

What is Zantac and what was it used for?

"Zantac" is the brand name of ranitidine, a medicine that was used to treat heartburn, reflux and stomach ulcers. It belongs to the H2 blocker class (H2 receptor antagonists), which are medicines that reduce the amount of acid the stomach produces [1]. You can review the medicine's page in the ClinicsJo directory via the Zantac (ranitidine) page.

Ranitidine is also mentioned in the famotidine leaflet among the medicines you should tell your doctor about if you are allergic to them before using famotidine [1]. This shows that the two belong to the same drug family.

Why was Zantac (ranitidine) withdrawn, and should I be worried?

Ranitidine was withdrawn in many countries around the world after an impurity called NDMA was found in the active ingredient itself, an impurity that can build up over time. Its everyday side effects (headache, dizziness, constipation or diarrhea) were mild and were not the reason for the withdrawal. Regulatory authorities described the cumulative risk as low, but stopping the medicine was the safer decision.

So there is no need to panic if you took it in the past. If old packs remain at home, do not use them. Instead, hand them to a pharmacy for safe disposal. If you find Zantac on sale today, it may be expired stock or a counterfeit product, so stay away from it.

The Jordan Food and Drug Administration (JFDA) is the body that regulates medicines and their prices in Jordan. Ask your pharmacist about the alternatives that are currently available and registered, and do not rely on an unreliable source.

What types of heartburn medicines are there, and how do they differ?

Common heartburn medicines fall into three main categories, each with a different role. The following table summarizes the differences:

No single category is "best" for everyone. The choice depends on how often and how severely you have symptoms, your other medicines and your overall health. Your pharmacist or doctor can help you decide.

Is famotidine a suitable replacement for Zantac?

Famotidine belongs to the same drug family (H2 blockers), but it does not carry the NDMA problem that led to the withdrawal of ranitidine, and it has almost no drug interactions. Sources describe it for treating ulcers and gastroesophageal reflux disease, and for cases in which the stomach produces excess acid [1]. It is available in prescription forms and in over-the-counter forms for treating heartburn and indigestion caused by certain foods and drinks [1].

How is famotidine used?

• The prescription form is usually taken once daily at bedtime, or two to four times daily. The usual dose is determined by your doctor or pharmacist [1].
• The over-the-counter form is usually taken once or twice daily. To prevent heartburn, it is taken 15 to 60 minutes before eating [1].
• Do not take more than two tablets or capsules of the over-the-counter form in 24 hours, and do not use it for more than two weeks unless your doctor directs you to [1].
• If symptoms persist for more than two weeks, stop the over-the-counter form and contact your doctor [1].
• If you forget a dose of a prescribed medicine, take it when you remember, unless the next dose is almost due. Do not double the dose [1].

What are the precautions?

Tell your doctor and pharmacist about all the medicines, vitamins and herbs you take, and about any drug allergies. Also tell them if you have kidney disease or difficulty swallowing, or if you are pregnant or breastfeeding [1]. The medicine may cause headache, dizziness, constipation or diarrhea. Rash, swelling of the face and throat, or difficulty breathing or swallowing are rare but require contacting your doctor immediately [1]. To learn more about this condition, read about drug allergy.

Doses for children are always based on weight and must be prescribed by a doctor or guided by a pharmacist. They should never be estimated at home.

To understand drug interactions in general, read the difference between a drug interaction and a side effect.

Do I need proton pump inhibitors, or is an antacid enough?

How often symptoms occur is the most important criterion. Occasional heartburn is common, but symptoms occurring twice a week or more, or damage to the lining of the esophagus, may indicate gastroesophageal reflux disease (GERD) [3]. To distinguish between the two, read the difference between occasional heartburn and GERD.

For reflux, a doctor may prescribe a proton pump inhibitor such as omeprazole or lansoprazole. Treatment usually lasts 4 or 8 weeks, depending on the severity of the reflux. If symptoms return after stopping, see your doctor, as you may need a long-term prescription [2]. If a proton pump inhibitor is not effective, the doctor may try an H2 blocker such as famotidine [2].

For chronic reflux and ulcers, proton pump inhibitors (pantoprazole, omeprazole and esomeprazole) are considered the most potent for healing, and pantoprazole is known as the least likely to interact with other medicines within this class. Do not start, stop or change any prescribed medicine without consulting your doctor [2].

When are tests necessary?

If medicines are not working or symptoms are severe, your doctor may refer you to a specialist for tests such as an endoscopy. They may also test for the H. pylori bacteria that may cause symptoms, which is treated with a combination of antibiotics and proton pump inhibitors [2]. Other tests include esophageal acid (pH) monitoring and esophageal motility testing [3]. To learn about these tests in the directory, see esophageal and stomach acid testing and wireless pH testing.

What relieves heartburn without medicine?

Lifestyle changes are an essential part of treatment and may reduce the need for medication. Sources recommend the following [2] [3]:

• Eat smaller, more frequent meals.
• Avoid eating two to four hours before bedtime, and do not lie down immediately after a meal.
• Avoid what triggers your symptoms, such as coffee, tomatoes, alcohol, chocolate, and fatty or spicy foods.
• Lose weight if you are overweight, and quit smoking.
• Wear clothing that is not tight around the waist.
• Raise the head of your bed by about 10 to 20 cm by placing blocks of wood, books or bricks under its legs. Do not use extra pillows, as they may increase pressure on the abdomen and worsen symptoms [2].

Some medicines, such as anti-inflammatory painkillers like ibuprofen, may cause or worsen heartburn [2]. Do not stop a prescribed medicine without consulting your doctor.

A hiatal hernia increases the likelihood of reflux [3]. To learn more, read Hiatal hernia: heartburn, difficulty swallowing and treatment options. For more on causes and treatment methods, see the acid reflux guide (GERD): causes, symptoms and treatment and the article When heartburn becomes a disease.

When should you see a doctor, and when should you go to the emergency room?

See a doctor if:

• Lifestyle changes and pharmacy medicines have not helped you [2].
• Heartburn occurs most days of the week [2].
• You feel food sticking in your throat or have difficulty swallowing [2] [3].
• You have repeated vomiting or unexplained weight loss [2].
• You notice black or tarry stools, which may indicate bleeding in the upper digestive tract and require prompt medical evaluation.
• You have needed the over-the-counter form of famotidine for more than two weeks [1].

Your doctor can offer an alternative or stronger treatment and rule out more serious causes of your symptoms [2].

Call emergency services (911) or go to the nearest emergency room if:

• Chest pain appears with shortness of breath, or pain in the jaw or arm, as these may be signs of a heart problem [3]. For an initial distinction, read Chest pain: heart, muscle or heartburn?.
• Swelling of the face, throat or tongue, or difficulty breathing or swallowing appears after taking a medicine [1].
• You vomit blood, or black stools are accompanied by dizziness or fainting.

How do I find the right doctor for heartburn in Jordan?

If heartburn is chronic, the most suitable specialty is usually gastroenterology and endoscopy. For an initial assessment, you can also start at the Ministry of Health's health centers located across the governorates, or with a family physician. On ClinicsJo, you can filter doctors and clinics by specialty and governorate, then read profiles and contact or book where the profile allows. Start with the acid reflux page, or with the directory of GERD evaluation clinics in Jordan. If you suspect H. pylori infection or an ulcer, review the pages for top doctors for H. pylori treatment and top doctors for stomach ulcer treatment. These pages are for information and searching only, and are not a recommendation of any specific doctor or clinic.

What should you check in a profile?

• The exact specialty and the services listed, such as endoscopy and acid testing.
• The location, governorate, working hours and how to contact them.
• Whether the profile allows direct booking or phone contact only.

Questions to ask your doctor

• Do I need tests such as an endoscopy or a H. pylori test, or should I start treatment?
• Which medicine is most suitable for me, for how long, and how is it stopped gradually when needed?
• Does it interact with my other medicines, or with pregnancy or breastfeeding?
• What signs should prompt me to return quickly?

Bring a written list of all your medicines and supplements [1].

Summary: what should I do now?

The era of Zantac has ended, and the current options are broader and more modern. Use antacids for occasional heartburn, and ask your pharmacist or doctor about famotidine if you need a medicine that reduces acid. If symptoms are chronic or accompanied by warning signs, seek medical evaluation, since chronic heartburn deserves a modern, clear treatment plan.

Frequently asked questions

Is Zantac still available?

Ranitidine, the active ingredient in Zantac, has been withdrawn in many countries since 2020 because of NDMA contamination. If you find Zantac on sale, it may be expired stock or a counterfeit product, so do not use it. Ask your pharmacist about the registered alternatives that are available in Jordan.

Should I be worried if I have previously used ranitidine?

There is no need to panic. The withdrawal was due to NDMA contamination, which can build up over time. Regulatory authorities described the cumulative risk as low, but stopping the medicine was the safer decision. If you have concerns or specific symptoms, raise them with your doctor or pharmacist.

What is the closest alternative to Zantac for treating heartburn?

Famotidine, which belongs to the same drug family, i.e., H2 blockers that reduce stomach acid, and does not carry the NDMA problem. For chronic reflux or ulcers, doctors often prescribe proton pump inhibitors instead. The usual dose is determined by your doctor or pharmacist based on your condition.

What is the difference between antacids, famotidine and proton pump inhibitors?

Antacids relieve symptoms quickly but only for a short time and do not address the cause. Famotidine reduces the amount of acid produced. Proton pump inhibitors, such as omeprazole, strongly reduce acid production and are used for reflux and ulcers, usually for 4 or 8 weeks depending on the severity of the condition.

How much over-the-counter famotidine can I use?

Do not take more than two tablets or capsules in 24 hours, and do not use it for more than two weeks unless your doctor directs you to. If heartburn or indigestion persists beyond that, stop the over-the-counter form and see your doctor to assess the cause.

When is heartburn a warning sign?

See a doctor if heartburn occurs most days, or is accompanied by difficulty swallowing, repeated vomiting, unexplained weight loss or black stools. If chest pain appears with shortness of breath or pain in the jaw or arm, call emergency services on 911 or go to the nearest emergency room.
