Procter & Gamble Co said on Friday that it is recalling some Vicks DayQuil Cold & Flu medicine that did not come in a childproof package.
While the label says the packaging is child-resistant, the so-called blister packs in the box are not.
There have been no reports of children accidentally taking the medication, P&G said.
Vicks DayQuil Cold & Flu 24-Count LiquiCaps Bonus Packs, which were sold only in the United States, are the only product affected by the latest voluntary recall, P&G said.
The U.S. Consumer Product Safety Commission said P&G is recalling 700,000 packages sold from September 2008 through this month.
The recall marks the latest issue for the company's Vicks brand. Last month, P&G voluntarily recalled about 120,000 bottles of Vicks Sinex nasal spray after finding bacteria in a small amount.
In late October, the U.S. Food and Drug Administration issued a warning letter to P&G over the marketing of Vicks DayQuil and NyQuil products with vitamin C. [ID:nWNAB7896]
DayQuil Cold & Flu is not for children under 12 years old, unless recommended by a doctor. If a child swallowed it, it could cause serious health problems or death, P&G said.
P&G said the FDA and CPSC supported the recall.
