What conditions are ranitidine 150 mg tablets used for?
Ranitidine hydrochloride 150 mg tablets are used to lower stomach acid. They are prescribed for conditions such as:
- Heartburn and acid indigestion (also called dyspepsia), including symptoms from gastroesophageal reflux disease (GERD) [1]
- Stomach and duodenal ulcers, to help them heal and reduce recurrence [1]
- Prevention of ulcers in people at risk from stomach acid–related injury [1]
How does ranitidine work for heartburn and ulcers?
Ranitidine blocks histamine H2 receptors on stomach acid-producing cells. With less acid production, it can reduce burning pain (heartburn), help ulcers heal, and lower the chance of symptoms returning [1].
How should ranitidine 150 mg be taken for symptoms vs. ulcers?
Ranitidine dosing depends on why it is being used (for example, short-term symptom control versus longer-term ulcer treatment). Your prescriber’s instructions or the product label should guide:
- Whether it’s taken once or twice daily
- How long treatment should continue
Because dosing schedules vary by indication, it’s important to follow the directions on your specific prescription or package instructions [1].
What side effects do people ask about most?
Common side effects reported with ranitidine can include dizziness, headache, constipation or diarrhea, and fatigue. If you develop severe reactions such as swelling of the face or trouble breathing, seek urgent care [1].
Important safety note
Ranitidine has been heavily scrutinized due to concerns about contamination with N-nitrosodimethylamine (NDMA), which affected its availability and prescribing in some places. If you currently have ranitidine 150 mg, check with your pharmacist or prescriber about whether it’s still recommended in your area and what alternatives may be safer or more appropriate [1].
