The company isn't sure how the boxes got to the woman's doorstep.
Officials: Boxes left on doorstep did not contain pills
KATY, TX
The woman said she found six boxes containing more than 400 Avandia pills -- a prescription drug for diabetes patients.
GlaxoSmithKline -- the makers of the drug -- looked into it, and the boxes were opened.
It turned out to be paper napkins. No pills or any other type of safety hazard were in the boxes, GSK officials said.
A GSK spokesperson says they were promotional items that were distributed a few years ago.
