NDMA is a probable human carcinogen (a substance that could cause cancer). FDA has determined that the impurity in some ranitidine products increases over time and when stored at higher than room temperatures may result in consumer exposure to unacceptable levels of this impurity. As a result of this immediate market withdrawal request, ranitidine products will not be available for new or existing prescriptions or OTC use in the U.S.</p><p><strong>BACKGROUND:</strong> Ranitidine is a histamine-2 blocker, which decreases the amount of acid created by the stomach. Prescription ranitidine is approved for multiple indications, including treatment and prevention of ulcers of the stomach and intestines and treatment of gastroesophageal reflux disease.</p><p><strong>RECOMMENDATION:</strong></p><ul><li><strong>Consumers:</strong> The FDA is also advising consumers taking OTC ranitidine to stop taking any tablets or liquid they currently have, dispose of them properly and not buy more; for those who wish to continue treating their condition, they should consider using other approved OTC products.</li><li><strong>Patients</strong>: Patients taking prescription ranitidine should speak with their health care professional about other treatment options before stopping the medicine, as there are multiple drugs approved for the same or similar uses as ranitidine that do not carry the same risks from NDMA. To date, the FDA's testing has not found NDMA in famotidine (Pepcid), cimetidine (Tagamet), esomeprazole (Nexium), lansoprazole (Prevacid) or omeprazole (Prilosec).</li><li><strong>Consumers and Patients:</strong>In light of the current COVID-19 pandemic, the FDA recommends patients and consumers not take their medicines to a drug take-back location but follow the FDA's recommended steps, available at: <a target="_blank" href="https://bit.ly/3dOccPG">https://bit.ly/3dOccPG</a>, which include ways to safely dispose of these medications at home.</li></ul><p>For more information visit the FDA website at: <a target="_blank" href="https://www.fda.gov/Safety/MedWatch/SafetyInformation">https://www.fda.gov/Safety/MedWatch/SafetyInformation</a> and <a target="_blank" href="https://www.fda.gov/Drugs/DrugSafety">https://www.fda.gov/Drugs/DrugSafety</a>.</p></div></div></section><section><div id="why" class="section"><div class="section-header"><div class="section-title"><h2>Why is this medication prescribed?</h2></div><div class="section-button"><button type="submit" aria-controls="section-1" role="button" title="Expand/Collapse section"><span class="icon icon-section-action">

Over-the-counter ranitidine is used to prevent and treat symptoms of heartburn associated with acid indigestion and sour stomach. Ranitidine is in a class of medications called H<sub>2</sub> blockers. It decreases the amount of acid made in the stomach.</p></div></div></section><section><div id="how" class="section"><div class="section-header"><div class="section-title"><h2>How should this medicine be used?</h2></div><div class="section-button"><button type="submit" aria-controls="section-2" role="button" title="Expand/Collapse section"><span class="icon icon-section-action">

It is usually taken once a day at bedtime or two to four times a day. Over-the-counter ranitidine comes as a tablet to take by mouth. It is usually taken once or twice a day. To prevent symptoms, it is taken 30 to 60 minutes before eating or drinking foods that cause heartburn. Follow the directions on your prescription or the package label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Take ranitidine exactly as directed. Do not take more or less of it or take it more often than prescribed by your doctor.</p><p>Dissolve ranitidine effervescent tablets and granules in a full glass (6 to 8 ounces [180 to 240 milliliters]) of water before drinking.</p><p>Do not take over-the-counter ranitidine for longer than 2 weeks unless your doctor tells you to. If symptoms of heartburn, acid indigestion, or sour stomach last longer than 2 weeks, stop taking ranitidine and call your doctor.</p></div></div></section><section><div id="other-uses" class="section"><div class="section-header"><div class="section-title"><h2>Other uses for this medicine</h2></div><div class="section-button"><button type="submit" aria-controls="section-3" role="button" title="Expand/Collapse section"><span class="icon icon-section-action">
