Rantac OD 300 Tablet CR
Prescription RequiredProduct introduction
Rantac OD 300 Tablet CR is used to treat conditions caused by excess stomach acid, such as gastroesophageal reflux disease (GERD) and peptic ulcer disease. It works by reducing the amount of acid produced in the stomach, thereby relieving symptoms such as heartburn, acidity, and stomach discomfort.
Rantac OD 300 Tablet CR helps promote the healing of stomach and intestinal ulcers and prevents them from recurring. It is also commonly prescribed to prevent heartburn and ulcers caused by the use of painkillers. Take it exactly as prescribed by your doctor. The dose and duration depend on your condition and response to treatment, so follow your doctor’s instructions carefully.
This medicine usually provides relief from indigestion and heartburn within a few hours, and it may only be needed for short-term use when symptoms occur. However, if you are taking it to prevent ulcers or manage ongoing acid-related conditions, your doctor may advise longer use. Taking it regularly can help prevent symptoms from returning. You can also support your treatment by eating smaller, more frequent meals and avoiding spicy or fatty foods.
Most people do not experience side effects while taking this medicine. However, common ones may include headache, constipation, diarrhea, or mild drowsiness. These effects are usually temporary and improve as your body adjusts to the medicine. Consult your doctor if they persist or cause discomfort.
Before starting Rantac OD 300 Tablet CR, inform your doctor if you have liver or kidney problems, as your dose may need adjustment. Also, tell your doctor about any other medicines you are taking, since some may interact with this one.
