NEW YORK (CBSNewYork) –– A popular weight loss drug is being recalled over tampering concerns.

The FDA is investigating after some bottles alli were found to be tampered with, drug maker GlaxoSmithKline said.

All weight loss products from U.S. and Puerto Rico retailers are being voluntarily recalled as the company believes that some packages of the product were tampered with and may contain product that is not authentic alli.

Consumers in seven states including New York, Alabama, Florida, Louisiana, Mississippi, North Carolina and Texas have reported suspected tampering.

“Safety is our first priority and we are asking retailers and pharmacies to remove all alli from their shelves immediately,” said Colin Mackenzie, President Consumer Healthcare North America.

Alli is a turquoise pill. The tainted bottles may contain tablets and capsules of different shapes and colors.
