Ranitidine Oral Uses
Ranitidine is used to treat ulcers of the stomach and intestines and prevent them from returning after treatment. This medication is also used to treat and prevent certain stomach and throat (esophagus) problems caused by too much stomach acid (e.g., Zollinger-Ellison syndrome, erosive esophagitis) or a backward flow of stomach acid into the esophagus (gastroesophageal reflux disease-GERD).
Ranitidine is known as an H2 histamine blocker. It works by reducing the amount of acid in your stomach. This helps heal and prevent ulcers and improves symptoms such as heartburn and stomach pain.
How To Use Ranitidine Oral
Dissolve each dose in 6 to 8 ounces (180 to 240 milliliters) of water before drinking. Do not chew or swallow the tablets whole. Do not dissolve the tablets on the tongue. After the tablet is completely dissolved in the water, drink the solution with or without food, usually once or twice daily or as directed by your doctor. If you are taking this medication once daily, it is usually taken after the evening meal or before bedtime.
The dosage and length of treatment are based on your medical condition and response to therapy. In children, dosage may also be based on body weight. Follow your doctor's instructions carefully. You may take other medications (e.g., antacids) for your condition as recommended by your doctor.
Take this medication regularly in order to get the most benefit from it. To help you remember, take it at the same time(s) each day. Do not increase your dose or take it more often than prescribed. Do not stop taking this medication without your doctor's approval because this may delay healing of the ulcer.
Tell your doctor if your condition does not improve or if it worsens.
