What is gabapentin?
Gabapentin is an anti-epileptic drug, also called an anticonvulsant. It affects chemicals and nerves in the body that are involved in the cause of seizures and some types of pain.
Gabapentin is used together with other medicines to treat partial seizures in adults and children at least 3 years old.
Gabapentin is also used to treat neuropathic pain (nerve pain) caused by herpes virus or shingles (herpes zoster) in adults.
Use only the brand and form of gabapentin your doctor has prescribed. Check your medicine each time you get a refill to make sure you receive the correct form.
The Gralise brand of gabapentin is indicated for the management of neuropathic pain only. It is not used for epilepsy.
Horizant is used to treat nerve pain and restless legs syndrome (RLS).
The Neurontin brand is used to treat seizures in adults and children who are at least 3 years old, in addition to neuropathic pain.
Gabapentin can cause life-threatening breathing problems, especially in older adults or people with COPD. Seek emergency medical attention if you have very slow breathing.
Some people have thoughts about suicide or behavior changes while taking gabapentin. Stay alert to changes in your mood or symptoms. Report any new or worsening symptoms to your doctor.
Avoid driving or hazardous activity until you know how gabapentin will affect you. Dizziness or drowsiness can cause falls, accidents, or severe injuries.
Do not stop using gabapentin suddenly, even if you feel fine.
