Summary

Brexpiprazole and Reserpine 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

What to do
Monitor blood pressure, sedation and mood changes. Reassess the need for reserpine if depression or marked sedation emerges.
