GREENVILLE, S.C. (WSPA) – A Greenville medical practice was sentenced after purchasing Botox that was not approved by the FDA, according to U.S. Attorney Beth Drake.

Neurology Associates of Greenville, P.A. pled guilty and was sentenced to 3 years of federal probation for receiving misbranded drugs in interstate commerce, Drake says.

The practice has also agreed to pay $300,000 to the U.S. due to the submission of Medicare claims for non-approved Botox.

The practice had a note on its door saying it closed on June 30, 2016. Patients who talked to 7News said they were told the doctor was relocating.

Plastic surgeons said they see how something like this could happen because practices are dependent and trustful of drug representatives. However, they said the doctor has an obligation to his patients to ask the right questions.

“In a world that’s so busy, it would be possible, I think, to hear this and not verify that it’s FDA approved, so we have to be vigilant about it,” Dr. Barry Bishop of Plastic Surgery Associates in Greenville said.

He also said patients should do their homework.

“You have to ask questions about the various products, and we as physicians have to ask questions,” Bishop said.

Although, Bishop said a non-FDA approved drug won’t necessarily hurt people.

“Non-FDA approved doesn’t mean it’s a dangerous or bad drug,” Bishop said. “It just hasn’t been studied for a specific situation.”

Investigators found that the practice bought non-FDA-approved Botox between the years of 2010 and 2013.
