Some need seconds: Some people may need a second injection of epinephrine, so always keep second Epipen handy or make sure you know how to use the second dose in your twinject.

Usually: About 25% of anaphylactic reactions will require a second dose of epi due to a dual or late phase reaction. If the epi is given in a timely manner, the immediate reaction should improve. However, a second dose can be given 5-10 minutes later if necessary. In my allergy experience (19 years) i've rarely needed to give a second dose---anecdotal.
