Gabapentin: What It Does and What You Need to Know

Gabapentin (often sold as Neurontin) treats seizures and nerve pain. It’s also used off-label for restless legs, certain pain syndromes, and sometimes anxiety—doctors prescribe it for problems where nerves are misfiring. If you or someone you care for was just given a gabapentin script, this page gives practical, no-nonsense facts so you know what to expect.

How gabapentin is used and typical dosing

Doctors usually start low and go slow. A common starting dose is 300 mg at night, then the doctor may increase to 300 mg two or three times daily. Effective doses range widely; some people need 900–3,600 mg per day depending on the condition and tolerance. Never double up after a missed dose without checking with your provider. Always follow the plan your prescriber gives you—dose and timing matter for both benefit and safety.

Gabapentin is taken by mouth and absorbed in the gut. Antacids with aluminum or magnesium can reduce how much gets into your system if taken at the same time, so separate them by a couple of hours when possible.

Side effects, risks, and interactions

Most common side effects are drowsiness, dizziness, coordination issues, and mild swelling (edema). Some people notice weight gain or fatigue. Because it affects the brain, avoid heavy machinery until you know how gabapentin hits you. Don’t mix gabapentin with alcohol or high-dose opioids—combining them can seriously slow breathing.

Stopping gabapentin suddenly can cause withdrawal or seizures for people who take it long term. If you need to stop, ask your prescriber about a gradual taper.

There’s growing concern about misuse when gabapentin is combined with other sedatives. If you take other CNS depressants (benzodiazepines, some sleep meds, or opioids), tell your doctor so they can adjust doses and monitor you closely.

Pregnancy and breastfeeding require a careful talk with your clinician—risks depend on the condition being treated and available alternatives.

If you’re unsure whether gabapentin is right for you, ask a clinician. Bring a list of your meds and health conditions so they can spot interactions. With the right dose and a plan for monitoring, gabapentin can be very helpful—just treat it like any strong medicine and respect the risks.
