Ulcer medicines: antacids & PPIs — pharmacist-reviewed guide

Also known as ulcer drugs, antacid, stomach acid medicine.

This page is general health information, not a diagnosis. Always consult a licensed clinician about your own health.

What this covers

Ulcer and acid-reflux medicines range from quick-acting antacids that neutralise stomach acid to proton-pump inhibitors (PPIs) that reduce acid production for longer-lasting relief. Many stomach ulcers are caused by an infection (H. pylori) that needs specific combination treatment to cure.

Safe-use guidance

  • Use antacids for occasional heartburn; if you need them most days, see a doctor rather than increasing use.
  • PPIs work best taken before a meal, usually in the morning — ask your pharmacist about timing.
  • If an ulcer is suspected, ask about H. pylori testing — treating the infection can cure the ulcer rather than just easing symptoms.
  • Avoid known triggers: NSAIDs, excess alcohol, smoking, and very late heavy meals.
  • Separate antacids from other medicines by a couple of hours, as they can block absorption of some drugs.

Cautions

  • Black or tarry stools, vomiting blood, or severe persistent stomach pain are emergency signs — go to a hospital immediately.
  • Long-term PPI use without review is not advisable; it should be reassessed periodically by a clinician.
  • Antacids can interact with antibiotics and other medicines, reducing their effect.
  • Persistent 'ulcer symptoms' in older adults or with weight loss need investigation, not just repeated self-medication.
