SPRINGFIELD, Ill. (WAND) - A bill to cap the cost of insulin in the state of Illinois is now headed to the governor's desk. 

On Thursday Senate Bill 667 passed the  Senate with a 43-1 vote. The bill is sponsored by State Senator Andy Manar. 

The bill would put a cap on co-payments for insulin at $100 per month for all patients no matter the supply they require. This would only apply to commercial insurance plans regulated by the state. 

“Thanks to countless grassroots advocates and the brave individuals who stepped up and shared their testimonies, the Illinois General Assembly just sent a clear message that our state will no longer allow pharmaceutical companies to take advantage of Illinoisans living with diabetes by charging exorbitant prices for lifesaving insulin medication,” Manar said.

The bill also requires the Department of Insurance, in conjunction with the Department of Human Services and the Department of Healthcare and Family Services, to issue an "insulin pricing report" to the public. 

The price of insulin has drastically increased in the U.S over the past few years. The drug price tag tripled from 2002 to 2013. 

Over 1.3 million people in Illinois rely on insulin. 

The bill will make Illinois the second state in the country to cap insulin payments. 

Gov. Pritzker is expected to sign the legislation into law. He released the following statement after the bill was passed: 

“Skyrocketing prescription drug prices are an enormous burden for too many Illinois families, and this legislation will significantly lower out-of-pocket costs for the 1.3 million Illinoisans that rely on insulin,” said Governor JB Pritzker. “It’s fitting that on World Diabetes Day, Illinois has taken bold action to protect our residents’ health, rather than force them to use lower quality medication or even ration their supply. We are proud that Illinois continues to be a national leader in ensuring health care is a right and not a privilege. This important step forward for lowering health care costs is the result of the tireless advocacy of Sen. Andy Manar, Rep. Will Guzzardi and so many other champions. I look forward to signing this legislation and continuing my commitment to ensuring Illinois residents have access to comprehensive, high-quality and affordable health care coverage.”
