Zantac Oral Uses and How to Use

  • 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

    Take this medication by mouth with or without food, usually once or twice daily or as directed by your doctor. It may be prescribed 4 times a day for some conditions. If you are taking this medication once daily, it is usually taken after the evening meal or before bedtime.

    Measure the dose carefully using a measuring spoon or a special medication spoon available from your pharmacist. Do not use household spoons or you may not get the correct dose.

    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 without your doctor's approval because this may delay healing of the ulcer.

    Inform your doctor if your condition does not improve or if it worsens.
