What happens when you use an epi pen without having anaphylactic shock?

Waste 100 bucks: An amazingly safe medication. In the seventies we used Epinephrine to treat acute asthma attacks giving kids 3 doses in 40 minutes. Sometimes they had nausea & vomiting. Sometimes they'd get a little hyper. The nausea & vomiting could also have been due to asthma itself. Anyway, expect slight but brief rise in pulse, mild muscle jitteriness, heightened alertness. All resolve in 30 minutes.
