About Rantac-Dom Tablet

Rantac-Dom Tablet belongs to a group of medicines called gastrointestinal agents used to treat gastro-oesophageal reflux disease (GERD) and peptic ulcers. Gastroesophageal reflux disease (GERD) occurs when stomach acid frequently flows back into the food pipe (oesophagus). Peptic ulcers are sores that develop on the inner lining of the intestine and stomach.

Rantac-Dom Tablet is a combination of two drugs, namely: Ranitidine (H2 receptor antagonist) and Domperidone (a dopamine antagonist). Ranitidine works by blocking histamine H2 receptors located on the stomach lining, thereby reducing gastric acid secretion. Domperidone works by increasing the movements and contractions of stomach muscles. Together, Rantac-Dom Tablet helps in treating acidity.

You are advised to take Rantac-Dom Tablet for as long as your doctor has prescribed it for you depending on your medical condition. In some cases, you may experience certain common side-effects such as dry mouth, stomach pain, constipation, headache, sleepiness, and dizziness. Most of these side-effects do not require medical attention and will resolve gradually over time. However, you are advised to talk to your doctor if you experience these side-effects persistently.

Consult your doctor if you are pregnant or breastfeeding. Rantac-Dom Tablet may cause sleepiness and dizziness, so drive only if you are alert.
