Taking 20-milligram doses of rabeprazole, such as Teva-Rabeprazole EC, helps heal and prevent conditions that include stomach and duodenal ulcers, erosive gastroesophageal reflux disease, and heartburn, states MedicineNet. Physicians combine the dosage with amoxicillin and clarithromycin daily to treat Helicobacter pylori infections, according to DailyMed.
Rabeprazole sodium, a proton pump inhibitor, relieves GERD by reducing secretions of gastric acid, explains DailyMed. To treat gastroesophageal reflux disease, physicians prescribe daily doses of rabeprazole for one to two months. Adverse reactions include pain, constipation and gas. Other possible reactions related to the drug include dizzziness, headaches and swelling of the extremities. In August 1999, the U.S. Food and Drug Administration approved rabeprazole for use, notes MedicineNet.
