Inject epinephrine if the person is unable to. If the person has a history of anaphylaxis, don't wait for signs of a severe reaction to inject epinephrine. Also, do not hesitate in giving an injection even if you are unsure that the symptoms are allergy related. The epinephrine will not cause any harm, but not giving the injection could be fatal.
Read and follow patient instructions carefully. Inject epinephrine into outer muscle of the thigh. Avoid injecting into a vein or buttock muscles. Do not inject medicine into hands or feet, which can cause tissue damage. If this happens, notify emergency room staff.
The person may need more than one injection if there's no improvement after the first. For an adult, inject again after 10 to 20 minutes. For a child, inject again after 5 to 30 minutes. A person should always go to the ER after an epinephrine injection, even if the symptoms subside.
