Ranitidine 300 tablet uses?

Ranitidine 300 mg tablets are an H2 blocker that reduces stomach acid. They’re used for conditions caused by excess acid such as:

- Active duodenal or gastric ulcers
- GERD (acid reflux) and erosive esophagitis
- Dyspepsia/indigestion and frequent heartburn
- Prevention of ulcer recurrence
- Zollinger-Ellison syndrome (rare)
- Stress-related or NSAID-related ulcer prevention in some settings

Typical dosing (varies by condition and country):
- For ulcers or GERD: 150 mg twice daily or 300 mg at bedtime
- For maintenance/recurrence prevention: 150 mg at bedtime (or 300 mg at bedtime in some cases)

Important notes:
- In many places, ranitidine has been withdrawn or recalled due to safety concerns (NDMA contamination). Check with your local regulator or pharmacist whether it’s available in your area and consider alternatives if not.
- If available, alternatives include famotidine, nizatidine, cimetidine, or proton pump inhibitors (e.g., omeprazole, pantoprazole).
- Always use under a clinician’s guidance, especially regarding dosing, duration, and potential drug interactions.
