Summary
Both drugs depress the central nervous system, so taking them together can deepen sedation, impair psychomotor performance and increase the risk of respiratory depression. Barbiturates may also lower blood pressure in patients who are prone to orthostasis from paliperidone.
What this interaction means in plain words
Paliperidone and Pentobarbital 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
Additive CNS depression from the antipsychotic and the barbiturate.
What to do
Monitor sedation, respiratory status and blood pressure, and start with the lowest effective doses. Warn patients against driving or operating machinery.
