If you’ve tried a lot of migraine medications or other therapies without much success, you might talk to your doctor about using gabapentin for migraines. While it might not be the right solution as a primary medication, it could be added to your arsenal along with other medications and tools like migraine glasses.
Gabapentin (GBP) is originally an anticonvulsant drug, but it’s sometimes used for migraine and headache prevention. The original use for gabapentin is for seizure preventative for patients with epilepsy, or to alleviate the uncomfortable symptoms of shingles.
Gabapentin is available in a generic version but also comes under the brand names of Horizant, Neurontin, and Gralise. It’s available orally as a liquid solution, capsule, or tablet for extended or immediate release. It can be taken with or without food.
Gabapentin and Migraine Prevention
Being an anticonvulsant, the theory behind using gabapentin for migraines is that its ability to calm nerve impulses could help avert migraines. Gabapentin may ease the brain’s electrical activities by settling excitatory neurotransmitters and blocking calcium channels.
However, this is mostly theoretical. Gabapentin’s exact role in migraine prevention isn’t well understood by researchers, and more research is needed to figure out what makes it work.
Gabapentin isn’t usually prescribed as a primary migraine preventative. It’s typically added to work in conjunction with other therapies, or used when other medications haven’t worked for the patient. As a preventative measure rather than an acute treatment, gabapentin needs to be taken continuously.
Gabapentin for Migraines Is an “Off-Label” Use
When a drug is used for something other than its purpose previously approved by the FDA, it’s called an off-label use. Since the FDA regulates the approval and testing of drugs (and not how doctors choose to prescribe them), your doctor is allowed to prescribe gabapentin for migraines if it seems like the right solution.
Dosing Gabapentin for Migraines
The recommended daily dose for gabapentin usually falls between 300 mg and 3,600 mg. Your dose may depend on your overall health, age, and other conditions.
If your doctor prescribes gabapentin, be careful to take only the recommended amount. Also talk to your doctor about how to wean off of it, should it become necessary to stop taking gabapentin.
What the Research Says
The research behind gabapentin for migraines is a bit mixed, but does show some promise.
The American Academy of Neurology (AAN) released a statement in 2013 which said there was insufficient evidence supporting gabapentin for migraine prophylaxis.
In 2014, a study conducted on gabapentin for episodic migraine found that some other antiepileptic drugs could be considered first-line migraine preventatives, but found inadequate evidence to recommend gabapentin for migraine prevention, saying it’s, “not effective and commonly causes adverse effects.”
A 2016 study of gabapentin for headache disorders did reveal some benefit. However, researchers stopped short of recommending it as a primary migraine therapy.
Side Effects of Gabapentin
LIke many other FDA-approved drugs, gabapentin could have side effects for many patients. Those include:
- Swelling of feet or limbs
- Unexpected or atypical eye movements
- Loss of coordination
- Blurry vision or other vision changes
