Neurontin (gabapentin) and Lyrica (pregabalin) are both anti-convulsants. There are some medications out there that work on chronic pain, but they are not officially pain meds. When I worked in the amputee program we used to use the anti-convulsant Tegretol for phantom limb pain and diabetic nerve pain. That was before Neurontin and Lyrica, though. They are both expensive and that is frustrating. Neurontin and Lyrica are both products of Pfizer, which has a program called Helpful Answers that provides prescription assistance for people without insurance coverage.
