Seven States Find Tampering of GlaxoSmithKline Weight-Loss Drug Alli

Twenty bottles of the popular weight-loss drug Alli, manufactured by GlaxoSmithKline, is suspected to have been tampered with, containing pills other than those mentioned on the label. At this time, the Food and Drug Administration (FDA) is currently investigating the case.

Such states as Alabama, Florida, Louisiana, Mississippi, New York, North Carolina and Texas reported bottles of suspicious drugs with pills of different shapes and colors than the original ones.

And though no side-effects have been reported at this time, the company is taking such findings very seriously.

"We are doing an investigation to determine any further action," said Glaxo spokeswoman Deborah Bolding, via Reuters.

Anyone who has come across a suspicious bottle of Alli is asked to call 800-671-2554.

Unfortunately, drug tampering has been an issue in the past. In 1982 in fact, seven people died after ingesting contaminated Tylenol, and in 2000, the FDA required that all medications use tamper-evident packaging in order to prevent such occurrences.

Warning signs that the bottle has been harmed may include a broken seal along with removal of the foil and/or no authentic Alli labeling on the bottle, according to the company's website.

Lot numbers and expiration dates that have contained contaminated bottles this far include: Carton Lot 14372, Expiration: 02/28/2016; Carton Lot 14395, Expiration: 02/28/2016; Carton Lot 14124, Expiration: 09/30/2015; Carton Lot 14267, Expiration: 01/31/2016; Carton Lot 14442, Expiration: 04/30/2016.
