RENNIE

This medicine contains two active substances, calcium carbonate and magnesium subcarbonate. Calcium carbonate is dietary calcium supplement or antacid. It is used for short-term alleviation of the symptoms of excess stomach acid or for providing extra calcium when necessary. Magnesium subcarbonate is a mineral which is used in cases of low amounts of calcium in the body. This medicine is used in cases of heartburn, acid reflux, episodic stomach pains and indigestion.
