(CNN) - Insurance companies in Illinois will now have to cover EpiPen injectors for kids.
Gov. J.B. Pritzker signed a law Tuesday requiring insurance policies to pay for EpiPens meant for people 18-years-old or younger.
EpiPens can stop an allergic reaction and save lives, but they cost families about $600 per injector. That price has increased dramatically in the last 10 years.
The governor says the measure is a big step forward in protecting children and families.
Illinois is the first state to mandate EpiPen insurance coverage for children.
The new law takes effect Jan. 1.
