Frequently Asked Questions

What is the typical gabapentin dose for neuropathy?
A common starting regimen is 300 mg at bedtime on day 1, then 300 mg twice daily on day 2, and 300 mg three times daily on day 3, increased as tolerated up to 1,800–3,600 mg per day in three divided doses. Lower doses are used in older adults and in kidney impairment. Always follow your prescriber's specific instructions.
How long does gabapentin take to work for neuropathy?
Some people notice modest pain reduction within the first week, but full benefit usually requires 2–8 weeks at an effective dose. If there is no meaningful improvement after several weeks at the maximum tolerated dose, an alternative medication is usually tried.
What are the most common gabapentin side effects?
Drowsiness, dizziness, unsteadiness, peripheral edema (swelling), weight gain, blurred vision, and difficulty concentrating are most common. Side effects are usually worst when starting or increasing the dose and often improve over 1–2 weeks. Falls are a particular concern in older adults.
Is gabapentin addictive?
Gabapentin has a low risk of addiction in the general population, but misuse and dependence have been reported, particularly in people with a history of substance use disorder or when combined with opioids. It is a controlled substance in some U.S. states. Do not stop suddenly — taper under medical supervision to avoid withdrawal.
What are alternatives to gabapentin?
Common alternatives include pregabalin (Lyrica), duloxetine (Cymbalta), venlafaxine, amitriptyline or nortriptyline, topical lidocaine 5% patches, and topical capsaicin. The right choice depends on coexisting conditions, side-effect tolerance, and cost.
