Summary
Paliperidone blocks alpha-1 receptors, which can blunt the pressor effect of epinephrine and leave beta-mediated vasodilation unopposed, causing hypotension. Both drugs may also affect cardiac rhythm and QT interval.
What this interaction means in plain words
Epinephrine and Paliperidone 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.
Epinephrine belongs to Endocrine; Paliperidone belongs to Central Nervous System.
Why it happens
Alpha-adrenergic blockade by paliperidone opposes epinephrine vasoconstriction, with possible additive proarrhythmic effects.
What to do
Monitor blood pressure and ECG when epinephrine is given, and in anaphylaxis do not withhold it but be ready to give fluids or an alternative vasopressor if hypotension persists.
What to ask your pharmacist
