I'm surprised--I was given this to control stomach acid when I had an ulcer and I use it now because I'm a blood thinner that makes my stomach bleed if I don;t take it.
It's a Nonprescription (over-the-counter) omeprazole is used to treat frequent heartburn (heartburn that occurs at least 2 or more days a week) in adults. Omeprazole is in a class of medications called proton-pump inhibitors. It works by decreasing the amount of acid made in the stomach.
It's done nothing for me with respect to excess mucus in my throat.
