Senior citizens and other Medicare enrollees can now get a break on the cost of their insulin. They won't pay more than $35 a month for each insulin prescription that's covered by their Medicare Part D plan. And they won't be subject to a deductible for insulin.

The House is set to vote Friday on the Inflation Reduction Act, which passed in the Senate on Sunday. Democrats have been touting the $430 billion climate, tax and healthcare bill as "life changing legislation," but with Republicans having voted to strip out any healthcare provisions not covered under Medicare, the question becomes whether the bill will have a ripple effect on drug prices for the general population.

Democrats have a plan to cap insulin at $35 a month. Republicans won't say if they'll block it.
