Uncovering the Black Market for Insulin

Uncovering the Black Market for Insulin

Skyrocketing insulin prices are making it difficult for diabetes patients to get the right medications. Here’s what you can do.

The Internet has always been a place for people to connect with drug sellers. The Dr. Oz Show discovered that some of the drugs in highest demand aren’t used recreationally. They are ones people need to stay alive.

The show recently conducted an undercover investigation into the black market for insulin, used by people with type 1 and type 2 diabetes to control their glucose levels and prevent life-threatening reactions, such as ketoacidosis, and diabetes-related complications, such as retinopathy and neuropathy.

The show found that insulin prices have skyrocketed—more than tripling in the past decade according to an analysis from IBM Watson Health. Globally, three companies dominate the insulin market and all have raised their prices dramatically. The original price of Humalog, for example, in 1996 was $21 a vial; it is now $275.

Why have prices gone up so steeply? Experts say it’s a result of inadequately designed insurance coverage in both private insurance and Medicare and alleged price-fixing by pharmaceutical companies. Another source of trouble: A rebate system that provides incentives for middlemen Pharmacy Benefit Managers, such as CVS, Express Scripts and UnitedHealth’s Optum, to accept high-priced drugs and not pass available savings on to consumers.

This is forcing many people to reduce their life-saving use of insulin. A study in JAMA Internal Medicine found that one in four diabetic patients reported rationing insulin because of the cost. Interestingly, very few of the patients surveyed were uninsured, but out-of-pocket costs were still prohibitively high—and, report the researchers, so were their blood sugar levels. No wonder many people are now buying insulin from strangers on the Internet.

The black market uncovered
To see how that happens, The Doctor Oz Show sent an investigative correspondent, armed with a hidden camera, out to buy some black market insulin. She contacted a seller she found online and was able to buy a box of insulin pens for $125 that usually costs $400.

Such deals may seem smart, but buying insulin on the sly can trigger health problems, even death; one of the other sellers the undercover correspondent met said he kept the insulin in the freezer, a move that erases the drug’s effectiveness in controlling blood sugar levels.

Remember, the way you store insulin matters, and the type you buy matters, too. Not all insulins work the same way, and some may not offer the timing or glucose control that you need. There are insulins that are rapid-acting, short-acting, intermediate-acting, long-acting and ultra-long acting. And, says, it’s easy to mix up:

  • Humalog and Humalog 75/25
  • Humalog and Humulin Regular
  • Humulin Regular and Humulin NPH
  • Humalog 75/25 and Humulin 60/30
  • Novolog and Humalog
  • Novolog 70/30 and Novolin 70/30 and Humulin 70/30
  • Novolin Regular and Novolin NPH

They cannot be substituted for one another without careful consultation with your doctor and redesign of your insulin administration plan.

So resist the temptation to buy on the sly. If you or a loved one cannot afford insulin:

  • The American Diabetes Association (ADA) suggests asking your doctor if you can use older human insulins in place of more costly newer analogues and opt for insulin in vials instead of in more costly pens.
  • The ADA also suggests you “talk to your doctor to ensure that your prescription reflects your medication usage each month to avoid multiple monthly copays.”
  • The ADA lists organizations and companies that provide info on pharmaceutical discount programs and databases such as

We also think that if you have type 2 diabetes, you should ask your doc about other glucose-control medications that may offer an alternative to insulin. One example: GLP-1 receptor agonists, such as Trulicity, that stimulate insulin production while suppressing the liver’s glucose output.

There are also a number of apps, including the Sharecare app for iOS and Android, which use GPS so you can compare insulin prices at pharmacies in your area.
