Omeprazole is used to treat certain stomach and esophagus problems (such as acid reflux, ulcers). It works by decreasing the amount of acid your stomach makes. It relieves symptoms such as heartburn, difficulty swallowing, and persistent cough. This medication helps heal acid damage to the stomach and esophagus, helps prevent ulcers, and may help prevent cancer of the esophagus. Omeprazole belongs to a class of drugs known as proton pump inhibitors (PPIs).
I had stomach hernia and an oesophagial hernia which were kept bearable most of the time. If my acid reflux started my vomiting and pain this could last for up to 3 days no other medication was strong enough to help.I had constant belching which was painful. I am a full time carer/wife for my husband and I needed to be able to care.
