What is the most important information I should know about epinephrine injection?
Before using this medication, tell your doctor if you have heart disease or high blood
pressure, a heart rhythm disorder, diabetes, or a thyroid disorder.
Tell your doctor if you also take digoxin (digitalis, Lanoxin, Lanoxicaps), quinidine
(Cardioquin, Quinaglute, Quinidex), an antidepressant such as Elavil, Pamelor, Sinequan, or
Tofranil, or an MAO inhibitor such as Marplan, Nardil, Azilect, Eldepryl, Emsam, or Parnate.
Do not inject epinephrine into a vein or into the muscles of your buttocks. Inject it
only into the fleshy outer portion of the thigh.
Accidentally injecting epinephrine into your hands or feet may result in a loss of
blood flow to those areas, and resulting
numbness. If this occurs, seek emergency medical
attention.
Seek emergency medical attention even after you use this medication to treat a severe
allergic reaction. The effects of epinephrine injection may wear off after 10 or 20 minutes. You
will need to receive further treatment and observation.
Before using epinephrine a second time, tell your doctor if your first injection caused
a serious side effect such as increased breathing difficulty, or dangerously high blood pressure
(
severe headache, blurred vision, buzzing in your ears,
anxiety,
confusion,
chest pain,
shortness
of breath, uneven heartbeats,
seizure).
Store the auto-injector device in the original tube it came in. Keep this tube at room
temperature away from direct sunlight, heat, and moisture. Do not refrigerate this medication, or
store it in a car.
What is epinephrine injection?
Epinephrine is a chemical that narrows blood vessels and opens airways in the lungs.
These effects can reverse severe low blood pressure, wheezing, severe skin itching, hives, and
other symptoms of an allergic reaction.
Epinephrine injection is used to treat severe allergic reactions (anaphylaxis) to insect
stings or bites, foods, drugs, and other allergens. Epinephrine is also used to treat
exercise-induced anaphylaxis.
Epinephrine auto-injectors such as EpiPen and EpiPen Jr. may be kept on hand for
self-injection by a person with a history of an severe allergic reaction.
Epinephrine injection may also be used for other purposes not listed in this medication
guide.
