Obtaining an Epi-pen prescription online is simple; visit Your Doctors Online and connect with a doctor anytime, anywhere. Our online doctor will ask about your symptoms to determine treatment.

What is Epi-Pen?

The Epi-pen is an auto-injector that delivers a dose of the hormone epinephrine, also known as adrenaline, into the body. This treatment functions by effectively alleviating the symptoms associated with anaphylaxis. Epipen delivers medicines quickly and effectively to patients with food allergies or other common triggers.

How to use an Epi-pen?

Hold the pen in a fist from the blue end facing up to the sky, check the window on the side of the pen, swing your hand back, and insert it into your thigh. If you are using it for someone else, follow the same method, but just have them sit and kneel before them and insert it in their thighs.

How does it work?

The EpiPen can quickly reverse life-threatening allergic reactions by injecting a measured dose of the hormone epinephrine. As soon as the device is activated, an injection of epinephrine is given into the thigh, causing the airways to dilate, the heart rate to increase, and the blood vessels to constrict. These influences lessen Anaphylaxis symptoms, such as shortness of breath and low blood pressure. The release of allergic mediators is also reduced by epinephrine. Treatment of severe allergic reactions with epinephrine requires prompt administration; however, users must still seek medical attention afterward.

What are the dosages used in Epi-pen?

Epi-pen contains drugs from the therapeutic classes of Adrenergic bronchodilators, Vasopressors, and Catecholamines. It is known by the brand name EpiPen and comes in dosage forms of 0.3 mg or 0.15 mg solution, vial, autoinjector syringe, and prefilled syringe.

Interactions and Precautions

  • When administering an EpiPen, caution is advised for people with certain health conditions. Epinephrine may affect cardiovascular disease, high blood pressure, diabetes, overactive thyroid, and glaucoma.
  • You shouldn’t use an Epi-pen to administer epinephrine if you’re allergic to drugs in the sympathomimetic family.
  • The expiration date and storage conditions of your EpiPens should be checked frequently. Epinephrine that has expired or been improperly stored may not work as well in a medical emergency. The EpiPen should be stored at room temperature, away from light, and before its expiration date.
  • Users should be instructed in the proper administration of the EpiPen. The injection system is meant to be used in the thigh muscle intramuscularly. The effectiveness may decrease if it is administered incorrectly. If you want your allergic reaction to be properly evaluated and treated, you should still go to the hospital, even if you’ve used an EpiPen.
  • Sometimes, a second dose may be needed if symptoms persist or reoccur. However, deciding to give a second dose requires discussion with medical professionals or emergency services.
  • Although epinephrine use during pregnancy and breastfeeding is widely accepted, the safety of this practice has not been thoroughly studied. Consequently, it is only suggested if the benefits outweigh the dangers.
