Omiz 20mg (Omeprazole) is a medication commonly used to treat conditions like acid reflux, gastroesophageal reflux disease (GERD), and stomach ulcers. It works by reducing the amount of acid produced in the stomach. Typically, Omiz is available in capsule form, with each capsule containing 20mg of omeprazole. The 14-capsule pack would generally be a two-week supply if taken once daily, but it's important to follow your doctor's prescribed dosage.
