(CNN)- EpiPens for children will now have to be covered by insurance companies in Illinois.
Gov. J.B. Pritzker signed a law Tuesday requiring insurance policies to pay “medically necessary epinephrine injectors for persons 18 years of age or under,” according to CNN.
Epipens can stop an allergic reaction and save lives, but they cost families about $600 each.
The price has gone up drastically in the last decade.
In a tweet on Tuesday, the governor said the measure is a “big step forward in protecting children and families.”
