Summary
Racemic epinephrine, usually given by inhalation, has beta-2 effects that can shift potassium into cells and slightly oppose succinylcholine's potassium rise. With systemic exposure, epinephrine may add to arrhythmia risk during anesthesia. The clinical effect is generally small.
What this interaction means in plain words
Epinephrine racemic and Succinylcholine have a small, usually unimportant interaction. Most people can take both; the pharmacist may still mention it so that any unexpected effect is recognised.
Why it happens
Beta-2 stimulation drives cellular potassium uptake; both agents can affect heart rhythm.
What to do
Monitor ECG and heart rate during anesthesia. Check potassium if large or repeated doses of epinephrine are given.

- Is there anything I should notice while taking both?
- Do I need to tell my doctor at the next visit?
