Lyrica is basically a stronger version of gabapentin, as far as I understand. Gabapentin is also prescribed for human fibromyalgia BTW (probably a lot more for that than for seizures). I have to go through a bit of a rigamarole to get gabapentin in Ireland for a dog as it is a human drug and has not been cleared for animal use thus there's some extra paperwork for the vet. My pharmacist thinks it is funny to do up the prescription for a dog!
