Gabapentin is prescribed to manage pain and inflammation. It is sold under the brand name Neurontin and is available as the generic Gabapentin. A standard supply is 90 300mg.
Pharmacy pricing is not regulated in the United States, so retailers set their own cash prices. Large retailers like Walmart and Costco typically offer lower prices on generics because they use prescriptions as a traffic driver. Chain pharmacies like CVS and Walgreens tend to charge significantly more.
Pain medications range from affordable generics like ibuprofen to more expensive nerve pain options. Always check whether a generic is available.
Shop around. The cheapest pharmacy (Costco at $7.50) charges significantly less than the most expensive option ($24.00). A quick call can save you real money.
Ask for the generic. If your doctor prescribed the brand-name Neurontin, ask your pharmacist whether the generic Gabapentin is available. In most states, pharmacists can substitute a generic unless the prescriber writes 'dispense as written.'
Use a discount card. Services like GoodRx, SingleCare, and WellRx can sometimes negotiate prices lower than retail cash. The estimated GoodRx low for Gabapentin is around $6.40.
Coverage depends on your specific plan and formulary. Most pain medications are covered under standard health insurance, typically in Tier 1 or Tier 2. If your copay is higher than the cash price above, it may be cheaper to pay out of pocket — ask your pharmacist to compare.
