-    prevent ulcers from bleeding

-    heal and prevent problems caused by acid in the food pipe (oesophagus) or to much acid in the stomach, which can cause pain or discomfort known as “indigestion”, “dyspepsia” or “heartburn”

-    prevent ulcers, which can be a side effect of some medicines used to treat arthritis especially in women during labour

-    clear up infection with the germ Helicobacter pylori when used with antibiotics For children (3 to 18 years) Ranitidine is used to:

-    heal ulcers in the stomach, or the part of the gut it empties into (the duodenum)
