(CNN) -- About 700,000 units of Vicks Dayquil cold medicine were recalled Friday after a finding that the packaging was not child-proof, according to the U.S. Consumer Product Safety Commission.

The recall affects Vicks Dayquil Cold & Flu 24-Count Bonus Pack Liquicaps with the UPC no. 3 23900 01087 1, according to the product safety group. The medicine was sold between September 2008 and December 2009.

The packaging -- which is not child-resistant and lacks the statement, "This package for households without young children" -- should be kept out of the reach of young children. If a child swallows several of the pills, the child could suffer "serious health problems or death," the commission said.

No injuries have been reported in relation to the recall.

People who bought the product can request a refund or coupon from manufacturer Proctor and Gamble Co. by calling them at 800-251-3374.
