Recognising overdose

Overdose typically presents as exaggerated versions of the medication's known side effects. With Gabapentin, that can include severe hypotension, marked dizziness, confusion, persistent vomiting, prolonged visual disturbances, syncope, or, in extreme cases, cardiovascular instability. Symptom severity scales with the amount taken and with co-ingestion of alcohol or interacting drugs.

Immediate action

Suspected overdose is a medical emergency. Stop further dosing immediately and contact emergency services or your local poison control. Do not induce vomiting unless instructed by a healthcare provider. According to the prescribing information, no specific antidote exists for most Neurological Medications agents — supportive care is the standard approach.
