The Consumer Products Safety Commission says that "child-resistant" caps on some bottles of cough and flu syrup aren't as sturdy as advertised.

That's a problem, because products implicated in the agency's latest recall announcement — Triaminic and Theraflu syrups and "warming liquids" — contain acetaminophen and diphenhydramine.

Those drugs are responsible for tens of thousands of poisoning incidents in children each year. Acetaminophen in large doses can be especially damaging to the liver.

To avoid the risk of poisoning, the consumer agency advises users to stop using the products any Triaminic or Theraflu "warming liquid" purchased between May 2010 and December 2011.

Novartis, the pharmaceutical company that makes the products, has received 12 reports of children unscrewing the caps on the faulty products. Four of those kids ingested the product, and one needed medical attention.
