What is the difference between Symjepi and EpiPen?
EpiPen and Symjepi are both intramuscular or subcutaneous injections use to treat allergic emergencies (anaphylaxis), for example to bees stings or peanuts. Unlike EpiPen, Symjepi does not come as an "autoinjector" but comes only as a prefilled syringe. Symjepi has a smaller size and may be more user-friendly than other products.

Like EpiPen, Symjepi (epinephrine) is a single-dose, prefilled syringe of 0.3 mg epinephrine used for emergency treatment of Type 1 allergic reactions such as insect stings, food allergies (like nuts or shellfish), or medications, among other severe allergic reactions.
Symjepi and EpiPen injectors are both designed for injection through clothing, but the users of Symjepi should be in a seated position prior to injection in the outer thigh, while the EpiPen can be used while standing. Seek medical attention immediately after using Symjepi or EpiPen.
Symjepi, from Adamis, was FDA-approved in June 2017 and is sold in a 2-pack like EpiPen.
Other brands of epinephrine include Auvi-Q from Kaleo and Adrenaclick from Impax. Generic alternatives are also available on the U.S. market for emergency epinephrine delivery.

What's the mechanism of action for epinephrine?
Epinephrine works by activating both alpha and beta receptors found in your body in response to a severe allergy (called anaphylaxis).
