Summary

Iloperidone is an atypical antipsychotic that commonly causes sedation and orthostatic hypotension, and baclofen adds further CNS depression and can lower blood pressure. The combination may increase drowsiness, dizziness and the risk of falls.

What this interaction means in plain words

Baclofen and Iloperidone 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.

Baclofen belongs to Musculoskeletal; Iloperidone belongs to Central Nervous System.

Evidence level: Low

Why it happens

Additive CNS depressant effects, with additional alpha-1 adrenergic blockade from iloperidone contributing to hypotension.

What to do

Monitor for sedation and orthostatic symptoms, particularly during iloperidone titration or baclofen dose increases. Reduce one dose if daytime impairment occurs.
