Lomotrigine — Uses, Dosage, Side Effects & Safety

Drug class: Antiepileptic (Anticonvulsant)

Overview

Lomotrigine is a prescription medication used to treat certain types of seizures in people with epilepsy and to help prevent mood episodes in adults with bipolar disorder. It works by stabilizing electrical activity in the brain, which helps reduce the frequency and severity of seizures and mood swings. Lomotrigine is often chosen because it generally causes fewer side effects than some other antiepileptic drugs. It is important to take this medication exactly as prescribed, as stopping suddenly can increase the risk of seizures or mood changes. Patients should be aware of the risk of serious skin reactions and report any rash or unusual symptoms to their healthcare provider immediately.
