Zantac (ranitidine hydrochloride) is a histamine-2 (H2) blocker medication clinically proven to reduce stomach acid production. It provides rapid and sustained relief from frequent heartburn, acid indigestion, and sour stomach, targeting the underlying cause of discomfort rather than merely masking symptoms. By inhibiting the action of histamine on stomach parietal cells, Zantac offers a therapeutic approach to managing gastroesophageal reflux disease (GERD) and other acid-related conditions, supporting mucosal healing and long-term digestive comfort.

Common use
Zantac is commonly used for the relief and prevention of heartburn associated with acid indigestion and sour stomach. It is also indicated for the treatment of gastroesophageal reflux disease (GERD), where stomach acid frequently flows back into the tube connecting the mouth and stomach. Additionally, healthcare providers may recommend Zantac for managing conditions such as erosive esophagitis, Zollinger-Ellison syndrome, and duodenal ulcers. It is often used prophylactically by individuals prior to consuming known trigger foods or beverages.
Dosage and direction
For OTC use in adults and children 12 years and older: The typical dosage is 75 mg (as ranitidine) orally with water, once or twice daily. To prevent symptoms, take 30 to 60 minutes before eating food or drinking beverages that cause heartburn. Do not take more than 2 tablets in 24 hours. For prescription strengths (e.g., 150 mg or 300 mg), always follow the specific dosing instructions provided by your healthcare professional. The dosage for pediatric patients under 12 or individuals with renal impairment must be determined by a physician.
Precautions
Before using Zantac, inform your healthcare provider if you have a history of kidney or liver disease, porphyria, or immune system disorders. Long-term use of acid-reducing medications may be associated with vitamin B12 deficiency; discuss monitoring with your physician if using for extended periods. Use with caution in elderly patients, as they may be more sensitive to side effects. If symptoms persist after 14 days of OTC use, discontinue and consult a doctor. Zantac is not intended for immediate relief; it may take 1–2 hours to feel the full effect.
Contraindications
Zantac is contraindicated in patients with known hypersensitivity to ranitidine or any component of the formulation. It should not be used by individuals who have previously experienced an allergic reaction to other H2 receptor antagonists. Patients with acute porphyria should avoid ranitidine due to the potential to precipitate attacks. Concomitant use with certain HIV medications (e.g., atazanavir, rilpivirine) is not recommended due to significant reductions in their plasma concentrations.
Possible side effect
Common side effects may include headache, dizziness, constipation, or diarrhea. Less frequently, patients may experience nausea, vomiting, stomach pain, or sleepiness. Rare but serious side effects can include mental/mood changes (e.g., agitation, confusion, depression), easy bruising/bleeding, signs of infection (e.g., fever, persistent sore throat), fast/slow/irregular heartbeat, or severe tiredness. Allergic reactions, though uncommon, may present as rash, itching/swelling (especially of the face/tongue/throat), severe dizziness, or trouble breathing.
Drug interaction
Ranitidine may interact with several medications. It can reduce the absorption of drugs that require an acidic gastric environment, such as ketoconazole, itraconazole, and gefitinib. It may alter the pharmacokinetics of warfarin, phenytoin, procainamide, and midazolam. Concurrent use with high-dose antacids is not recommended without medical supervision. As ranitidine is primarily renally excreted, drugs that affect kidney function may alter its clearance. Always inform your healthcare provider of all medications, supplements, and herbal products you are taking.
Missed dose
If you miss a dose of Zantac, take it as soon as you remember. However, if it is almost time for your next dose, skip the missed dose and resume your regular dosing schedule. Do not double the dose to catch up. For OTC use, which is typically taken as needed, this scenario is less applicable; simply take the next dose when symptoms occur or as preventive measure before a trigger meal, ensuring you do not exceed the maximum daily dosage.
Overdose
In case of suspected overdose, seek immediate medical attention or contact a Poison Control Center. Symptoms of overdose may include exaggerated side effects such as abnormal heart rhythms, hypotension, and altered mental status. Gastric lavage or activated charcoal may be employed if ingestion was recent. Supportive measures, including monitoring of vital signs and ECG, are standard. There is no specific antidote for ranitidine overdose; treatment is symptomatic and supportive.
Storage
Store Zantac at room temperature (68°F to 77°F or 20°C to 25°C), away from light, moisture, and heat. Keep the bottle tightly closed and out of reach of children and pets. Do not store in the bathroom or near the kitchen sink. Discard any unused medication after the expiration date printed on the packaging. Do not flush medications down the toilet or pour them into a drain unless instructed to do so.

Reviews
Clinical studies and user reports consistently highlight Zantac’s efficacy in providing reliable and rapid relief from acid-related symptoms. Many users appreciate its preventive capabilities when taken before known triggers. Healthcare professionals often recommend it as a first-line option for mild to moderate GERD and occasional heartburn due to its favorable safety profile and predictable pharmacokinetics. Some note the convenience of OTC availability, though adherence to dosage guidelines is emphasized. Long-term users should discuss periodic evaluation with their physician to ensure ongoing appropriateness of therapy.
