you are thinly-built, inject yourself into the upper outer quarter (quadrant) of the buttock.
There is a nerve that crosses the buttocks; hitting this nerve can cause paralysis. Therefore, you must only inject into the upper outer quarter (quadrant) of the buttocks
Apply firm, even pressure (not jabbing
motion) to the injector until it pushes the needle into your buttocks. Hold the injector firmly in place for at least 10 seconds.
Firm pressure automatically triggers the coiled spring mechanism. This plunges the needle through the clothing into the muscle and at the same time injects the antidote into the muscle tissue.
Carefully remove the autoinjector from your injection site.
