News about recent price increases for EpiPen and EpiPen Jr (Mylan) may have patients asking about other options for emergency treatment of anaphylaxis. Adrenaclick and its generic equivalent (epinephrine injection auto-injector) are the only other epinephrine auto-injectors currently available in the US. According to Impax (the manufacturer of both the brand and generic products), Adrenaclick is no longer being manufactured; the generic product will continue to be marketed after supplies of Adrenaclick are depleted. Auvi-Q (Sanofi), an epinephrine auto-injector that was approved by the FDA in 2013, was removed from the market in 2015 due to inconsistencies in delivery of epinephrine doses, including failure to deliver the drug.1

Adrenaclick and its generic equivalent are similar to EpiPen and EpiPen Jr in size and functionality, but they are not considered interchangeable with the EpiPen products due to differences in device design and instructions for use. One pack (two auto-injectors) of EpiPen or EpiPen Jr costs $608.60. One pack of Impax's generic auto-injectors costs $395.20.2

According to Mylan, generic versions of EpiPen and EpiPen Jr will soon become available at about half the cost of the brand-name products.
