Rennie Dual Action Chewable Tablets provide fast, powerful relief from heartburn, indigestion and acid reflux by working in two ways:
1. Antacids (calcium carbonate and magnesium carbonate) get to work within two minutes, powerfully neutralising excess acid in the stomach.
2. Alginic acid soothes the burning pain in your chest, forming a protective barrier over the stomach to prevent acid escaping into the food pipe.
Suitable for Adults and children over 12 years
