Ranitidine
(Ranitidine)Ranitidine Overview
Ranitidine is used to treat ulcers of the stomach and intestines and prevent them from coming back after they have healed. Ranitidine is also used to treat certain stomach and throat (esophagus) problems (such as erosive esophagitis, gastroesophageal reflux disease-GERD, Zollinger-Ellison syndrome). It works by decreasing the amount of acid your stomach makes. It relieves symptoms such as cough that doesn't go away, stomach pain, heartburn, and difficulty swallowing. Ranitidine belongs to a class of drugs known as H2 blockers. Ranitidine is also available without a prescription. Ranitidine is used to prevent and treat heartburn and other symptoms caused by too much acid in the stomach (acid indigestion). If you are taking Ranitidine for self-treatment, it is important to read the manufacturer's package instructions carefully so you know when to consult your doctor or pharmacist. Ranitidine has been withdrawn from the US market due to problems with safety. A possible cancer-causing impurity has been found in some ranitidine products.
How to Use Ranitidine
Take Ranitidine by mouth with or without food as directed by your doctor, usually once or twice daily. It may be prescribed 4 times a day for some conditions. If you are taking Ranitidine 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 (such as antacids) for your condition as recommended by your doctor. Take Ranitidine 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. If you are using nonprescription ranitidine for self-treatment of acid indigestion or heartburn, take 1 tablet by mouth with a glass of water as needed. To prevent heartburn, take 1 tablet by mouth with a glass of water 30-60 minutes before eating food or drinking beverages that cause heartburn. Do not take more than 2 tablets in 24 hours unless directed by your doctor. Do not take for more than 14 days in a row without talking with your doctor.
