Zantac & Ranitidine Lawsuit

Ranitidine hydrochloride, sold under the brand name Zantac and others, is a popular drug used to treat heartburn, acid reflux, and ulcers. The FDA ordered a full market withdrawal of ranitidine products in April 2020 after NDMA, a probable human carcinogen was detected.

The History of Zantac


Ranitidine, sold under the brand name Zantac and others, is a popular drug used to treat various gastrointestinal issues. Ranitidine products work by decreasing stomach acid production, helping to prevent or temporarily relieve heartburn, acid reflux, ulcers, and other similar ailments.

It was discovered in England in 1977, came into commercial use in 1981, and went on to become one of the most commonly prescribed medications in the country. By 2019, there were over 13 million active ranitidine prescriptions in the United States alone. Certain preparations of ranitidine products also became available over the counter (OTC). For example, in the U.S., consumers could purchase 75 and 150-mg tablets OTC from their local drug stores until the FDA ordered a full market withdrawal of ranitidine products in April 2020.

Other Names for Zantac

Other Names for Zantac

Zantac is the most common brand name for the drug ranitidine hydrochloride or ranitidine HCL. It was manufactured and sold by Sanofi in the United States. Before the FDA recalled all ranitidine products, generic ranitidine hydrochloride products were widely available from other manufacturers, including Apotex and Sandoz.

Recommended Zantac Dosage

Zantac Dosage

Zantac (ranitidine) was given in various forms, including capsules, tablets, and syrups, as well as injectables. Prescription Zantac oral tablets and capsules could be taken once or twice daily, with or without food, as directed by a doctor. Some patients were instructed to take Zantac up to 4 times a day. Ultimately, the exact dosage was based on the patient’s condition and responsiveness to treatment.

Patients who used nonprescription Zantac to treat symptoms of indigestion or heartburn took one tablet by mouth with a glass of water as needed. To prevent heartburn, patients could take one tablet by mouth 30-60 minutes before a meal. Zantac’s label directions warned not to take more than two tablets in a 24-hour period or for more than 14 days in a row unless instructed by a doctor.

Zantac Side Effects

Zantac Side Effects

Common side effects of Zantac include diarrhea, constipation, and headache. Some patients reported dizziness, skin rash, nausea, vomiting, stomach cramps, and drowsiness. In rare circumstances, especially among the elderly or those who were especially ill, there were reports of central nervous system issues (including depression and hallucinations), cardiovascular trouble (such as tachycardia), and issues impacting the liver and lungs.

Zantac Overdose Risk & Signs

Zantac Overdose

Overdosing on Zantac or other ranitidine products is very rare but not impossible. Taking much more than the recommended dosage of prescription or OTC Zantac could build up dangerous levels of the drug in the body. Symptoms of a Zantac overdose typically include trouble walking and low blood pressure that results in dizziness or fainting.

How Does Zantac Interact with Other Drugs?

Zantac Interaction

Because ranitidine products like Zantac work by decreasing the amount of acid your stomach produces, it should not be taken with other drugs that need stomach acid to help the body properly absorb them. This could include certain azole antifungals (like itraconazole), atazanavir, delavirdine, pazopanib, and dasatinib, among others. Importantly, Zantac shouldn’t be taken with other products that contain ranitidine or other H2 blockers, including cimetidine, famotidine, and nizatidine.

Zantac Cancer Lawsuit

FDA Zantac Recall

 In September 2019, a probable carcinogen (a substance that could cause cancer) called NDMA was detected in ranitidine products, including Zantac. The FDA asked manufacturers to recall the drug and its generic forms pending investigation and urged consumers to seek other OTC alternatives. NDMA is commonly ingested in food and water but not in levels expected to lead to an increased risk of cancer. In the instance of Zantac and other ranitidine products, the FDA was concerned about the impact of sustained, higher levels of exposure to the impurity.

The FDA Zantac Recall

Additional testing confirmed that NDMA levels in ranitidine drugs like Zantac could increase over time, especially when stored at higher temperatures. Ultimately, it was determined that NDMA impurities present in Zantac and other ranitidine products exceeded acceptable levels. In April 2020, the FDA requested a full market withdrawal of all ranitidine products in the United States.

Zantac’s Rise and Fall

 At the height of its popularity, Zantac became one of the world’s first-ever drugs to top $1 billion in annual sales. By 2019, before the drug was recalled by the FDA, there were over 13 million active prescriptions in the United States alone. This suggests that doctors considered Zantac and its generic forms an extremely viable treatment for heartburn and gastrointestinal issues. However, once the probable carcinogen NDMA was linked to ranitidine products, prescriptions and over-the-counter availability of the drugs abruptly halted.

Risk of Zantac Addiction

While it was available, there were no reported instances of ranitidine products, including Zantac, becoming habit-forming.

Alternative Remedies for Heartburn & Acid Reflux

There are many other ways to treat and prevent acid reflux, heartburn, and other conditions that Zantac was used to address. For example, lifestyle changes can go a long way. Stop smoking and drinking, as that decreases the esophagus’s ability to function properly. Proper diet and weight management are also key.

Patients may also prevent issues by avoiding large meals, eating meals earlier, or cutting out trigger foods altogether. Some people find relief by waiting at least 3 hours before lying down after a meal and elevating the head of their bed if they experience heartburn at night. Loose-fitting clothing can also help improve symptoms, as tighter clothes can put pressure on your abdomen.
