(WHTM)– Pennsylvania Attorney General Dave Sunday issued a warning to Pennsylvanians taking GLP-1 drugs to be wary of counterfeits ahead of summer.

Sunday said Pennsylvanians taking these drugs should ensure they are getting them from a licensed pharmacy. As demand for GLP-1 drugs rises, so does the counterfeit market for diabetes control and weight-loss drugs.

“These counterfeit products flooding the market can cause harm, and I strongly advise anyone shopping for GLP-1 drugs to use extreme caution,” Attorney General Sunday said. “I continue to urge the FDA to use its investigative, inspection, and enforcement powers to protect consumers.”

Sunday was involved in a multi-state coalition letter sent to the Food and Drug Administration, advising them to crack down on these counterfeit drugs that often come from foreign countries.

As summer approaches, more people are looking to embark on a weight loss journey. Those looking to take GLP-1 drugs such as Mounjaro, Zepbound, Ozempic, and Wegovy should take the proper steps to ensure they are getting medication from a proper source, Sunday says.

Consumers are encouraged to report suspicious products to the FDA and the Pennsylvania Office of the Attorney General.
