Overdose and treatment: In overdose up to 15 g, no unexpected adverse reactions were reported.
In the post-marketing experience, the most commonly reported adverse events observed when Pregabalin was taken in overdose included affective disorder, somnolence, confusional state, depression, agitation, and restlessness. Seizures were also reported.
Treatment of pregabalin overdose should include general supportive measures and may include hemodialysis if necessary.
Management of mild to moderate toxicity: Treatment is symptomatic and supportive.
Management of severe toxicity: Treatment of pregabalin exposure is largely supportive in nature with careful attention to airway protection in severe cases. Hypotension is usually mild responding to intravenous fluid boluses. If hypotension persists, administer dopamine or norepinephrine. Admit all severely symptomatic patients. Treat seizures with IV benzodiazepines or barbiturates.
