Tiagabine (tiagabine hydrochloride) — Uses, Dosage, Side Effects & Safety

Drug class: Antiepileptic (Anticonvulsant)

Overview

Tiagabine is a prescription medication used to help control certain types of seizures in people with epilepsy, specifically partial (focal) seizures. It is usually prescribed as an add-on therapy when other antiepileptic drugs are not fully effective. Tiagabine works by increasing the levels of gamma-aminobutyric acid (GABA), a natural chemical in the brain that helps calm nerve activity. By enhancing GABA's effects, tiagabine helps reduce the likelihood of abnormal electrical activity that leads to seizures. Key points for patients: Take tiagabine exactly as prescribed, do not stop suddenly without consulting your doctor, and report any new or worsening symptoms, especially mood changes or unusual thoughts.
