Humalog without insurance costs $95 per 3 ml cartridge, let's say it's a $100. This would mean that this child needs 37 cartridges for 3 months, or 12 cartridges per month, 3 per week.
That's a pretty crazy amount of insulin. I'm a T1 diabetic, that doesn't eat particularly healthy, and I need 2-3 cartridges a month, almost an order of magnitude less than the person in the article.
I don't think those numbers are right.
