Neurontin (gabapentin) — what it is and when people use it

Neurontin is the brand name for gabapentin. Doctors prescribe it most often for nerve pain (including diabetic neuropathy) and certain types of seizures. It doesn’t work like typical painkillers — it calms overactive nerve signals. That makes it useful when burning, tingling, or sharp nerve pain won’t respond to usual pain meds.

How Neurontin is used

Common starting doses are 300 mg once daily, then increased over days or weeks to 300 mg two or three times daily. Typical effective ranges fall between 900 mg and 2,400 mg per day, split across doses. Some people need up to 3,600 mg daily under close supervision. Important: kidneys clear gabapentin, so doctors cut doses for people with reduced kidney function.

Timing matters. Take gabapentin at roughly the same times each day and split the total daily dose. If you miss one dose, take it when you remember unless it’s almost time for the next dose — don’t double up. Never stop suddenly; tapering down with your doctor lowers the chance of withdrawal or seizure risk.

Safety tips & what to watch for

Common side effects include dizziness, sleepiness, unsteadiness, and mild swelling of the legs. These symptoms are more common when treatment starts or the dose increases. Seniors have higher fall risk, so balance and coordination changes deserve attention.

Gabapentin can cause mood changes, including worsening depression or suicidal thoughts in a small number of people. Tell your prescriber right away if you notice new or worsening mood or behavior changes.

Certain drugs and products affect how gabapentin works. Antacids with aluminum or magnesium may reduce absorption, and combining gabapentin with alcohol, opioids, or other sedatives can amplify drowsiness and breathing problems. Always list gabapentin on your medicine list and ask your pharmacist about interactions.

Misuse and dependence have been reported. Stick to prescriptions and doses your doctor gives. If you feel it’s not working or side effects are bad, you and your clinician can try lower doses, different timing, or an alternative medication.

Extra tips: ask for kidney function testing before you start and during treatment if you have kidney disease; keep a simple symptom log (pain scores, sleep, mood) to share with your clinician; avoid driving until you know how it affects you; store gabapentin safely and out of reach.
