Zantac How to Take

Zantac (Ranitidine) belongs to the class of medications called H2-antagonists. Zantac (Ranitidine) is used to reduce the amount of acid secreted by the stomach in order to reduce ulcer and heartburn pain or to assist in healing of ulcers. It is used to treat stomach and duodenal (intestinal) ulcers, and prevent them from recurring. It is also used to treat GERD (Gastroesophageal reflux disease) (GERD) and Zollinger-Ellison Syndrome.

Prescription Zantac (Ranitidine) is used to treat and prevent stomach ulcers caused by non-steroidal anti-inflammatory drugs (NSAIDs); to prevent bleeding caused by stress ulcers for very ill people; to prevent a second episode of bleeding in the digestive tract caused by bleeding ulcers; and to prevent inhalation of stomach acid during surgery, for people who are considered at risk of this complication.

The over-the-counter form of Zantac (Ranitidine) is used to treat conditions where a reduction of stomach acid is needed, such as acid indigestion, heartburn, or sour or upset stomach. It can also be used to prevent these symptoms when they are associated with eating food or drinking beverages.

Zantac (Ranitidine) may be available under multiple brand names and/or in several different forms. Any specific brand name of Zantac (Ranitidine) may not be available in all of the forms or approved for all of the conditions discussed here. As well, some forms of Zantac (Ranitidine) may not be used for all of the conditions discussed here.

Your doctor may have suggested Zantac (Ranitidine) for conditions other than those listed in these drug information articles. If you have not discussed this with your doctor or are not sure why you are taking Zantac (Ranitidine), speak to your doctor. Do not stop taking Zantac (Ranitidine) without consulting your doctor.

Do not give Zantac (Ranitidine) to anyone else, even if they have the same symptoms as you do. It can be harmful for people to take Zantac (Ranitidine) if their doctor has not prescribed it.

Zantac Dosage

The recommended adult dose of Zantac (Ranitidine) ranges from 150 mg daily to 150 mg twice daily or 300 mg once daily depending on the condition being treated. Zantac (Ranitidine) may be taken with or without food.

When used over-the-counter to treat acid indigestion, heartburn, or sour or upset stomach, the usual dose for adults and children 16 years of age or older is 75 mg to 150 mg taken when symptoms appear. If symptoms persist for more than 1 hour or return after 1 hour, you may take a second dose of the same strength. To prevent symptoms brought on by consuming food or beverages, take the dose 30 to 60 minutes before eating food or drinking beverages that are expected to cause symptoms. The maximum dose is 300 mg every 24 hours. Do not take it in this manner for more than 2 weeks without seeking medical advice.

The usual dose of Zantac (Ranitidine) injection is 50 mg every 6 to 8 hours given intravenously (into a vein) or intramuscularly (into a muscle).

If you are using the oral liquid form of Zantac (Ranitidine), use an oral syringe to measure each dose of the liquid, as it gives a more accurate measurement than household teaspoons.
