Summary
Tiagabine is an anticonvulsant that commonly causes dizziness, somnolence and fatigue, which may add to amisulpride's sedation. Antipsychotics can lower seizure threshold, so seizure control should also be watched.

Amisulpride and Tiagabine can affect each other. The combination is often manageable, but it may need a change of dose, a change of timing, or extra checks while both are taken.
Why it happens
