Emazole Control 20mg gastro-resistant tablets are designed to help alleviate the symptoms of reflux. This condition causes inflammation and pain in the food pipe, leading to a painful sensation in the chest rising up to the throat or a sour taste in the mouth. Emazole Control works by reducing the amount of acid produced by the stomach for at least 24 hours. It may take 2-3 days of consecutive use before symptoms start to improve. Each tablet is film-coated for easy swallowing.
