Unless you have a heart condition you don’t have to be concerned about the increased heart rate.
The reason you should go to the ER is because the Epi wears off, it’s only a temporary relief. “
Not according to my (otherwise healthy) grandkids’ allergist who is a top allergy doc on LI. The heart rate is affected by a shot of adrenalyn or dose of epinephrine, and anyone who has been given an epi shot should immediately be brought to the ER for monitoring.
