Months after the company faced Congressional investigations over alleged price gouging for its brand name EpiPen, Mylan has released a generic version of the emergency allergy treatment in the US. The generic is reportedly half the price of the brand name version, whose price skyrocketed above $600 this summer.

The EpiPen is filled with epinephrine and when injected can counter the effects of a severe allergic reaction. Peanut allergy sufferers, for example, rely on it when they go into life-threatening anaphylactic shock.

The brand name auto-injector’s price has risen by more than 480 percent since 2009, to more than $600 for a pack of two, as CBS News reported in August. The actual cost of the medication inside the EpiPen is only a few bucks, though.
