No. Tecta is one of a class of drugs called proton pump inhibitors that reduce acid in the stomach. It is used to treat several conditions such as gerd, ulcers, ; esophagitis. By lowering the acid it is giving your stomach lining time to heal. Also avoid stomach irritants such as nicotine, caffeine and alcohol.
