A member asked:
How long can epinephrine affect your heart?
A doctor has provided 1 answer
A few minutes: The half-life of Epinephrine is about 2 minutes. We constantly release small amounts. This is increased by the "fight or flight" reflex, and when administered medically. The most common use is in local anesthesia, and the effects wear off quickly.
