A recent study has shown that the cost of insulin is continuing to skyrocket. From 2002-2004, the cost of insulin was $4.34 per millimeter, and by 2011-2013, the cost of insulin in the United States had reached $12.92 per millimeter. A significant increase was also seen in per-patient insulin spending – $231.48 to $736.09 – and insulin spending was higher than all other diabetes drugs combined.
This analysis also indicated that the cost of popular oral diabetes drugs have either dropped in price or have not experienced a significant cost increases. For example, metformin fell from $1.24 per tablet in 2002 to $0.93 in 2013.
These findings were published in the Journal of the American Medical Association on April 6, 2016.
