PHOENIX - The outcry over the steep prices for an EpiPen has prompted some in the Phoenix area to put their own medication up for sale with a price tag that's hundreds of dollars cheaper than the manufacturer's.

A handful of sellers are offering EpiPens for anywhere between $100 and $200, which may seem like a bargain compared to the $600 listed cost, but a Valley doctor warned that purchasing one could be dangerous.

"If you do not get your EpiPens from a licensed professional, it is fraud," said Dr. Andrew Carroll, a physician at the Renaissance Medical Group in Chandler. "It’s illegal. You’re never supposed to transfer from one person to another person, ever."

12 News called one of the sellers, who claimed he put his medication up for sale at a discounted price to help out someone who may not be able to afford it.

"If I can pass it forward to someone who actually needs it, like a child or an adult, you know, I don’t need them," the seller said.

Dr. Carroll warns that if a drug doesn't come from a pharmacist or a doctor, the user is taking a risk with what they're taking.

"The potential consequences are maybe this didn’t come from the United States," he said. "Maybe this is a Chinese mockup. Maybe they’re giving you something that’s already used and not effective."

If the user were to have a serious medical complication or even death, Dr. Carroll said the seller may be liable for any criminal charges.
