"Long-acting insulin pens will be available at pharmacies for $11 per pen — or $55 for a five-pack — beginning Jan. 1. The pens are interchangeable with glargine, the generic alternative for Lantus, a once-a-day injection that regulates blood sugar. An equivalent amount of Lantus sells to pharmacies for more than $92, according to data compiled by the governor’s office, but consumers may pay a different price based on their insurance."
