Rabiace D 30mg/20mg Capsule SR is a combination medicine used to treat gastroesophageal reflux disease (Acid reflux). Gastroesophageal reflux disease (GERD) is a chronic (long-term) condition in which there is an excess production of acid in the stomach. Rabiace D 30mg/20mg Capsule SR reduces the amount of acid your stomach makes and relieves the pain associated with heartburn and acid reflux. You should take it exactly as it is prescribed for it to be effective. Some simple lifestyle changes can help reduce the symptoms of GERD. Think about what foods trigger heartburn and try to avoid them; eat smaller, more frequent meals; try to lose weight if you are overweight, and try to find ways to relax. Do not eat within 3-4 hours of going to bed.
