What is the most important information I should know about gabapentin?
Some people have thoughts about suicide while taking this medicine. Children taking gabapentin may have behavior changes. Stay alert to changes in your mood or symptoms. Report any new or worsening symptoms to your doctor.
Do not stop using gabapentin suddenly, even if you feel fine.
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 in adults to treat nerve pain caused by herpes virus or shingles (herpes zoster).
The Horizant brand of gabapentin is also used to treat restless legs syndrome (RLS).
The Neurontin brand of gabapentin is also used to treat seizures in adults and children who are at least 3 years old.
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.
Gabapentin may also be used for purposes not listed in this medication guide.
What should I discuss with my healthcare provider before taking gabapentin?
You should not use gabapentin if you are allergic to it.
To make sure gabapentin is safe for you, tell your doctor if you have ever had:
- kidney disease (or if you are on dialysis);
- depression, a mood disorder, or suicidal thoughts or actions;
- a seizure (unless you take gabapentin to treat seizures);
- liver disease;
- heart disease; or
- (for patients with RLS) if you are a day sleeper or work a night shift.
Some people have thoughts about suicide while taking this medicine. Your doctor should check your progress at regular visits. Your family or other caregivers should also be alert to changes in your mood or symptoms.
It is not known whether this medicine will harm an unborn baby. Tell your doctor if you are pregnant or plan to become pregnant.
Seizure control is very important during pregnancy, and having a seizure could harm both mother and baby. Do not start or stop taking gabapentin for seizures without your doctor's advice, and tell your doctor right away if you become pregnant.
Gabapentin can pass into breast milk, but effects on the nursing baby are not known. Tell your doctor if you are breast-feeding.
How should I take gabapentin?
Follow all directions on your prescription label. Do not take this medicine in larger or smaller amounts or for longer than recommended.
The Horizant brand of gabapentin should not be taken during the day. For best results, take Horizant with food at about 5:00 in the evening.
Both Gralise and Horizant should be taken with food.
Neurontin can be taken with or without food.
If you break a Neurontin tablet and take only half of it, take the other half at your next dose. Any tablet that has been broken should be used as soon as possible or within a few days.
Do not crush, chew, or break an extended-release tablet. Swallow it whole.
Measure liquid medicine with the dosing syringe provided, or with a special dose-measuring spoon or medicine cup. If you do not have a dose-measuring device, ask your pharmacist for one.
If your doctor changes your brand, strength, or type of gabapentin, your dosage needs may change. Ask your pharmacist if you have any questions about the new kind of gabapentin you receive at the pharmacy.
Do not stop using gabapentin suddenly, even if you feel fine. Stopping suddenly may cause increased seizures. Follow your doctor's instructions about tapering your dose.
Wear a medical alert tag or carry an ID card stating that you have seizures. Any medical care provider who treats you should know that you take seizure medication.
This medicine can cause unusual results with certain medical tests. Tell any doctor who treats you that you are using gabapentin.

Store the liquid medicine in the refrigerator. Do not freeze.
What happens if I miss a dose?
Take the missed dose as soon as you remember. Be sure to take the medicine with food. Skip the missed dose if it is almost time for your next scheduled dose. Do not take extra medicine to make up the missed dose.

What should I avoid while taking gabapentin?
This medicine may impair your thinking or reactions. Be careful if you drive or do anything that requires you to be alert.
