Cimetidine tablets contain cimetidine which is a histamine H2 antagonist. It helps to reduce the natural production of acid in the stomach.
They are used to treat and relieve:
• the symptoms of peptic ulcers which occur in the stomach or intestine (gut)
• oesophageal reflux disease which can be caused when food and acid from the stomach washes back into the food pipe (oesophagus). This can cause a burning feeling in the chest known as heartburn
• a rare condition called Zollinger-Ellison syndrome when the stomach produces very large amounts of acid.
This medicine may also be prescribed for a range of other medical conditions where a reduction of acid production in the stomach is needed, or to protect your stomach from other medicines (such as non-steroidal anti-inflammatories).
• suppress the immune system (e.g. ciclosporin, tacrolimus)
