Maine Republican Senator Susan Collins is joining a bipartisan group of Senators to introduce a bill to cap the cost of insulin at $35 per month.

The bill would cap the cost for people on private and employer insurance plans, on which most Americans rely.

The Endocrine Society is calling the measure “historic legislation” to protect access to life-saving medication for millions of people with diabetes.

Collins says it would directly address the root problems in the insulin market that are driving high list prices.

“Tens of millions of Americans rely on insulin as part of their daily treatment, and for many, it is literally a matter of life and death,” said Senator Collins. “I have heard far too many stories from people in Maine and across the country who have been forced to ration their insulin because of the cost, and that is simply unacceptable.”

If signed into law, the bill, known as the INSULIN Act, would address a disparity in access to cheaper insulin.

A $35 monthly cap on out-of-pocket insulin costs already exists for Medicare patients. The Inflation Reduction Act of 2022 created it.

The bill would also create a pilot program to provide insulin to the uninsured.

Senator Collins was joined in introducing the legislation by Jeanne Shaheen (D-NH), Reverend Raphael Warnock (D-GA), and John Kennedy (R-LA).
