Hello and welcome to ‘Ask A Doctor’ service. I have reviewed your query and here is my advice. Gabapentin is a medication which is used to treat partial seizures, neuropathic pain, hot flashes and restless legs syndrome. Common side effects of Gabapentin include dizziness, fatigue, drowsiness, ataxia, swelling of extremities, nystagmus and tremor. A small number of people may experience depression, suicidal thoughts/attempts, or other mental/mood problems. You need to seek medical attention promptly if you notice any unusual/sudden changes in your mood, thoughts, or behaviour. Hope I have answered your query. Let me know if I can assist you further.
