How And When To Take Gabapentin - NHS

How long to take it for

If you have epilepsy, it's likely that when your condition is under control you'll still need to take gabapentin for many years.

If you have nerve pain, when your pain has gone you'll continue to take gabapentin for several months or longer to stop it coming back.

If you forget to take it

If you forget a dose, take it as soon as you remember, unless it's within 2 hours of your next dose. In this case, skip the missed dose and take your next dose at the usual time.

Never take 2 doses at the same time. Never take an extra dose to make up for a forgotten one.

If you have epilepsy, it's important to take this medicine regularly. Missing doses may trigger a seizure.

If you forget doses often, it may help to set an alarm to remind you. You could also ask your pharmacist for advice on other ways to help you remember to take your medicine.

If you take too much

Taking too much gabapentin can cause unpleasant side effects.

Stopping gabapentin

It's important you do not suddenly stop taking gabapentin, even if you feel better. Stopping gabapentin suddenly can cause serious problems.

If you have epilepsy, stopping gabapentin suddenly can cause seizures that will not stop.

If you're taking it for any reason and stop suddenly, you may have severe withdrawal symptoms, including:

• anxiety
• difficulty sleeping
• feeling sick
• pain
• sweating

It's possible to prevent withdrawal seizures and other symptoms by gradually reducing the dose of gabapentin.

Do not stop taking gabapentin without talking to your doctor first. You'll need to reduce your dose gradually.
