Common use
Zantac is commonly used for the relief and prevention of heartburn, acid indigestion, and sour stomach. It is indicated for managing symptoms associated with gastroesophageal reflux disease (GERD), such as regurgitation and difficulty swallowing. Additionally, it may be used to treat conditions involving excess stomach acid, including Zollinger-Ellison syndrome, and to prevent ulcers in certain high-risk patients. Some healthcare providers recommend it for occasional use before consuming known trigger foods or beverages.
Dosage and direction
For OTC use in adults and children 12 years and older: Take 1 tablet (75 mg) with a glass of water as needed, not to exceed 2 tablets in 24 hours. Do not use for more than 14 days continuously unless directed by a physician.
For prescription-strength dosing (150 mg or 300 mg), follow your healthcare provider’s instructions precisely. Typical adult dosing for ulcer treatment is 150 mg twice daily or 300 mg once daily. Take with or without food. Do not crush, chew, or break tablets unless specified. For liquid formulations, use the measuring device provided.
Precautions
- Do not use if you have a history of allergy to ranitidine or other H2 blockers.
- Consult a healthcare professional before use if you are pregnant, planning pregnancy, or breastfeeding.
- Seek medical advice if you have kidney or liver disease, porphyria, or a weakened immune system.
- This medication may mask symptoms of stomach cancer; proper diagnosis is essential before long-term use.
- Avoid alcohol and smoking, as they can increase stomach acid and worsen underlying conditions.
- Not recommended for children under 12 years of age unless prescribed by a doctor.
Contraindications
Zantac is contraindicated in individuals with known hypersensitivity to ranitidine or any component of the formulation. It should not be used by patients with a history of acute porphyria. Concomitant use with certain HIV medications (e.g., atazanavir, rilpivirine) is not recommended due to significant reductions in their efficacy. Use is also contraindicated in patients with severe renal impairment unless under strict medical supervision with adjusted dosing.
Possible side effect
While generally well-tolerated, some individuals may experience side effects, including:
- Headache
- Dizziness
- Constipation or diarrhea
- Nausea or vomiting
- Abdominal discomfort
- Sleepiness or fatigue
- Rarely: confusion, rash, hair loss, changes in heart rate, or liver enzyme elevations
Most side effects are mild and transient. Discontinue use and seek medical attention if you experience signs of an allergic reaction (e.g., swelling, difficulty breathing, severe dizziness) or symptoms suggesting liver dysfunction (e.g., dark urine, jaundice).
Drug interaction
Zantac may interact with several medications by altering gastric pH or competing for metabolic pathways. Notable interactions include:
- Reduced absorption of ketoconazole, itraconazole, and certain antifungals
- Decreased efficacy of atazanavir, delavirdine, and rilpivirine (HIV protease inhibitors)
- Altered levels of warfarin, theophylline, phenytoin, and procainamide due to CYP450 inhibition
- Potential increased risk of bone fractures with long-term, high-dose use
- Possible interference with the absorption of vitamin B12 and iron
Always inform your healthcare provider of all medications, supplements, and herbal products you are taking.
Missed dose
If you miss a dose of prescription Zantac, take it as soon as you remember. 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 occasional OTC use, take only as needed according to label instructions.
Overdose
Symptoms of overdose may include vomiting, restlessness, rapid heartbeat, hypotension, and confusion. In severe cases, overdose can lead to respiratory depression or seizures. There is no specific antidote for ranitidine overdose; treatment is supportive and symptomatic. Seek immediate medical attention or contact a poison control center if an overdose is suspected.
Storage
Store at room temperature (15–30°C or 59–86°F) in a dry place, away from light and moisture. Keep the bottle tightly closed. Do not store in the bathroom. Keep all medications out of reach of children and pets. Do not use after the expiration date printed on the packaging.
