Summary
Antipsychotics with alpha-adrenergic blocking activity can blunt or reverse the pressor effect of epinephrine, leaving beta-mediated vasodilation and hypotension. Both agents may also affect the QT interval and heart rhythm. Racemic epinephrine is mostly given by inhalation, so systemic exposure is generally low.
What this interaction means in plain words
Epinephrine racemic 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.
Why it happens
Alpha-adrenergic blockade by paliperidone opposes epinephrine vasoconstriction, with possible additive proarrhythmic effects.
What to do
Monitor blood pressure and heart rhythm when systemic epinephrine is needed. If hypotension occurs, prefer a pure alpha agonist such as norepinephrine or phenylephrine.
What to ask your pharmacist
- Should I take them at different times of day?
- Does the dose of either medicine need to change?
- Is there anything I should avoid, such as alcohol or certain foods, while on both?
