EpiPen JR (Epinephrine, also known as adrenaline) is the drug form of a hormone naturally produced in our body by the adrenal glands. This life-saving medication acts quickly to reverse the symptoms of allergic reactions by opening up airways, accelerating heart rate, raising dropping blood pressure, and changing hives. It also quickly reduces the swelling of the face, lips, and throat.
Epinephrine is derived from an amino acid called tyrosine. It is grouped as catecholamines which are hormones made by the adrenal gland. Norepinephrine and dopamine are also referred to as catecholamines as they are both synthesized by tyrosine.
EpiPen, also known by its generic name as epinephrine, is a prescription-only brand name medication made by Mylan. EpiPen was initially approved in 1989, but its active ingredient, epinephrine was first synthesized in 1906.
It’s always best, when possible, to avoid the allergy trigger that causes your severe allergic reaction. However, if exposure does occur, auto-injectable epinephrine like EpiPen is used to help prevent anaphylaxis and should be given quickly.
Several epinephrine products come in an auto-injector pen that can be used by the patient, parent, teacher, school nurse, or any bystander. The injection is given in the thigh, and can even be given through clothing. The pen has similar functionality as Trulicity.
Epinephrine is also available in regular EpiPens.
