How to Take Zantac for Allergies

Zantac, the brand name for ranitidine, is a histamine-2 blocker that is more commonly associated with treating gastro-esophageal reflux disorder (GERD), rather than with allergies. However, Zantac has been found to be effective in treating hives and esophagitis, the inflammation of the esophagus. These are two conditions that can be symptoms of food allergies. Histamine blockers reduce the amount of acid in the stomach and alter the way histamines interact with the allergen.

Instructions

Difficulty: Easy

1. Discuss your allergies with your physician. There may be other antihistamine medications he may want you take before trying Zantac to reduce your symptoms. Inform him of any other medications or supplements you take before you start a new medication.
2. Let your doctor know if you are pregnant or nursing before you take Zantac for your allergies. Zantac is a category B medication, meaning it usually does not pose a risk to unborn babies. It is a good idea to use caution when taking any medication during pregnancy.
3. Read the dosage information carefully. Zantac is available over the counter and by prescription, and the dosage instructions may vary. Take a skipped dose as soon as you remember it, unless it is almost time for the next dose.
4. Keep your Zantac in a safe place that does not become exceedingly hot or cold and is out of the reach of children. Avoid storing your medication in the bathroom, as moisture may affect its potency.
5. Drink at least 8 oz. of water when taking Zantac. Swallow the tablet whole without crushing, breaking or chewing it. This will allow the time-release feature of the medication to work effectively.
6. Limit your intake of alcoholic beverages when taking Zantac. Alcohol can often increase the side effects of a drug. You can also risk further damage to the lining of your esophagus if you are taking Zantac to treat an inflamed esophagus.
7. Research the side effects that may occur when using Zantac. These includes headache, dizziness, drowsiness and insomnia. Serious side effects include shortness of breath, unexplained weakness and swelling in your face or throat and should be brought to a doctor's attention immediately.
8. Give Zantac time to work on your allergy symptoms. The medication may eliminate hives relatively quickly. Esophagitis can sometimes take weeks or months to heal, even after the allergen is removed.

Tips & Warnings

• Be careful using Zantac if you have kidney or liver disease. Your doctor will be able to assess whether Zantac is a safe treatment for your allergies.
