19 January 2019 - Lisa Crook was lucky. She saved $800 last year after her insurance company started covering a new, less expensive insulin called Basaglar that was virtually identical to the brand she had used for years.

With Basaglar, “I’ve never had my insulin cost drop so significantly,” said Crook, a legal assistant in Dallas who has Type 1 diabetes.
