Gralise is used to relieve nerve pain following shingles (a painful rash due to herpes zoster infection) in adults. This condition is called postherpetic neuralgia. Gabapentin belongs to a class of drugs known as antiseizure drugs (also called anticonvulsant or antiepileptic drugs).
How to use Gralise
Read the Medication Guide provided by your pharmacist before you start taking gabapentin and each time you get a refill. If you have any questions, ask your doctor or pharmacist.
Take this medication by mouth as directed by your doctor, usually once a day with the evening meal. The dosage is based on your medical condition and response to treatment.
Swallow this medication whole. Do not crush or chew sustained-release tablets. Doing so can release all of the drug at once, increasing the risk of side effects. Also, do not split sustained-release tablets unless they have a score line and your doctor or pharmacist tells you to do so. Swallow the whole or split tablet without crushing or chewing.
During the first 2 weeks of treatment, your doctor may gradually increase your dose so your body can adjust to the medication.
Take this medication regularly to get the most benefit from it. To help you remember, take it at the same time each day.
Do not take this medication more often or increase your dose without consulting your doctor. Your condition will not improve any faster, and your risk of side effects will increase.
Do not stop taking this medication without consulting your doctor. Some conditions may become worse when this drug is suddenly stopped. Your dose may need to be gradually decreased.
Antacids containing aluminum or magnesium may interfere with the absorption of this medication. Therefore, if you are also taking an antacid, it is best to take gabapentin at least 2 hours after taking the antacid.
Different forms of gabapentin (such as immediate-release, sustained-release, enacarbil sustained-release) are absorbed in the body differently.
