CVS is now selling a rival generic version of Mylan's EpiPen at about one-sixth of its price, The Associated Press reported Jan. 12.

A week later, Kaléo, a private pharmaceutical company, said in a Jan. 19 news release it would be offering its own version of the injector with $0 out-of-pocket cost for patients with commercial insurance.

CVS Health Corp., the nation's second-largest drugstore chain, said it cut the price of the generic version of Adrenaclick nearly in half.

Kaléo's version, called AUVI-Q, will be available for free to those with a household income of less than $100,000 and do not have government or commercial insurance, the release said. The offer is through the company's access program. The cash price of the injector is $360.
