Summary
Ephedrine is a sympathomimetic, and antipsychotics with alpha-blocking activity may reduce its pressor response. Stimulants may also worsen psychotic symptoms, while haloperidol is sedating, so their effects partly oppose each other.
What this interaction means in plain words
Ephedrine and Haloperidol have a small, usually unimportant interaction. Most people can take both; the pharmacist may still mention it so that any unexpected effect is recognised.
Ephedrine belongs to Cardiovascular; Haloperidol belongs to Central Nervous System.
Why it happens
Pharmacodynamic opposition: alpha-adrenergic and dopaminergic blockade versus sympathomimetic stimulation.
What to do
Monitor blood pressure and heart rate and titrate ephedrine to response.
What to ask your pharmacist
- Is there anything I should notice while taking both?
- Do I need to tell my doctor at the next visit?
