Perrigo Co. says it is voluntarily recalling four types of liquid pain, cough and cold drops packaged with syringes that could prove inaccurate when measuring doses for children.

The company declares the recall will cost about $2 million.

The recalled products are Cherry Flavor Infant Pain Reliever 160 mg Acetaminophen (0.5 oz. and 1.0 oz.), Grape Flavor Infant Pain Reliever 160 mg Acetaminophen (0.5 oz. and 1.0 oz.), Cherry Flavor Cough and Cold Infant Drops (0.5 oz.) and Cherry Flavor Decongestant and Cough Infant Drops (0.5 oz.).

In a statement, the Food and Drug Administration says the oral syringes contained in the packages are not marked to measure doses under 1.6 milliliters, which could be prescribed for children under 2, weighing less than 24 pounds.

It added ingesting too much acetaminophen, a pain-relieving ingredient, can cause liver damage.

Products were distributed nationally at retail chains under 34 different store-brand labels including CVS, Target Corp. and Walgreens.
