Antiepileptic

Gabapentin (Neurontin)

Gabapentin · ガバペン

Gabapentin exists in Japan (Gabapen 200–400 mg) but only for epilepsy, so the huge off-label use for nerve pain, anxiety and sleep seen in the US does not happen here. Visitors taking it for pain should bring their own supply under the 1-month rule and expect Japanese doctors to offer pregabalin instead.
