Heartburn & Indigestion

Zantac provides long lasting relief from indigestion and heartburn. Your stomach makes acid which helps digest your food. Sometimes your stomach can produce too much acid and it can flow back into your oesophagus (the tube that connects your throat to your stomach) causing heartburn.

Zantac belongs to a group of medicines called H2 Antagonists (also known as H2 Blockers)  Instead of just neutralising your excess stomach acid like antacids, H2 antagonists work by preventing your stomach from producing too much acid in the first place.

Zantac Extra tablets control excess acid for 24 hours, to bring you effective and long lasting relief, day & night. Zantac Extra - One tablet provides rapid, long lasting relief from acid indigestion and heartburn.

Active ingredient: Ranitidine 300mg (as hydrochloride)
