- Non-systemic relief with a favorable safety profile for appropriate patient populations
- Enables dietary flexibility by mitigating postprandial acid-related discomfort
Common use
Zantac is commonly used for the relief and prevention of heartburn associated with acid ingestion and GERD. It is also indicated for the treatment of active duodenal ulcers, maintenance of healed duodenal ulcers, and pathological hypersecretory conditions such as Zollinger-Ellison syndrome. In over-the-counter formulations, it is used for the relief of occasional heartburn, acid indigestion, and sour stomach.
Dosage and direction
For occasional heartburn (OTC use):
- Adults and children 12 years and older: Take 1 tablet (75 mg) with 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 indications (under medical supervision):
- Active duodenal ulcer: 150 mg twice daily or 300 mg once daily for 4–8 weeks.
- GERD: 150 mg twice daily.
- Hypersecretory conditions: 150 mg twice daily; may be titrated upward based on gastric acid output.
Take with or without food. Tablets should be swallowed whole; do not crush or chew unless specified (e.g., effervescent tablets). Follow healthcare provider instructions for individualized dosing.
Precautions
- Not recommended for use in children under 12 years of age without medical advice.
- Consult a healthcare professional if symptoms persist beyond 14 days of self-treatment or worsen.
- Use with caution in patients with renal impairment; dosage adjustment may be necessary.
- Not intended for immediate relief of heartburn; allow 30–60 minutes for onset of action.
- Avoid concomitant use with other acid-reducing agents unless advised by a physician.
- Inform your doctor if you are pregnant, planning pregnancy, or breastfeeding.
Contraindications
- Hypersensitivity to ranitidine or any component of the formulation.
- Patients with a history of acute porphyria.
- Concomitant use with certain HIV protease inhibitors (e.g., atazanavir, rilpivirine) due to reduced absorption and efficacy.
Possible side effect
Most side effects are mild and transient. Common adverse reactions may include:
- Headache
- Constipation or diarrhea
- Nausea or vomiting
- Abdominal discomfort
- Drowsiness or fatigue
Rare but serious side effects require immediate medical attention:
- Signs of allergic reaction (rash, itching, swelling, severe dizziness, trouble breathing)
- Irregular heartbeat
- Mental/mood changes (e.g., agitation, confusion, depression)
- Jaundice (yellowing of skin or eyes)
- Unusual bruising or bleeding
Drug interaction
Zantac may interact with several medications by altering gastric pH or competing for metabolic pathways:
- Reduced absorption of ketoconazole, itraconazole, atazanavir, and rilpivirine.
- Altered bioavailability of diazepam, warfarin, phenytoin, and procainamide; monitoring is advised.
- Potential increased risk of QT prolongation when used with other QT-prolonging agents.
- May mask symptoms of gastric malignancy; avoid delayed diagnosis with prolonged unsupervised use.
Missed dose
If you miss a dose, take it as soon as you remember. If it is almost time for the next dose, skip the missed dose and resume the regular schedule. Do not double the dose to catch up.
Overdose
Symptoms of overdose may include vomiting, restlessness, hypotension, tachycardia, and altered mental status. In cases of suspected overdose, seek immediate medical attention or contact a poison control center. Treatment is supportive and may include gastric lavage or activated charcoal if ingestion was recent.
Storage
Store at room temperature (15–30°C or 59–86°F) in a dry place, protected from light and moisture. Keep out of reach of children and pets. Do not use after the expiration date printed on the packaging.
