Summary

Both drugs cause sedation, so taking them together can produce greater drowsiness, impaired psychomotor performance and dizziness. Hydroxyzine also has a QT-prolonging potential, which adds modest cardiac concern in vulnerable patients.

What this interaction means in plain words

Hydroxyzine and Lurasidone 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.

Hydroxyzine belongs to Respiratory; Lurasidone belongs to Central Nervous System.

Evidence level: Moderate

Why it happens

Additive CNS depression from H1 antihistaminic and antipsychotic effects, with possible additive QT effects.

What to do
