Incorrect markings on dosing cups sold with Perrigo Company's children's cough syrup have led the firm to pull two batches of its grape-flavored syrup and three batches of its cherry-flavored syrup from CVS and Rite Aid stores.
"Use of these products according to labeled instructions with an affected dosing cup is unlikely to result in serious side effects, and no reports related to overdose have been received to date," according to a news release from Perrigo. "Consumers should be aware that an overdose of Guaifenesin DM may cause hyper excitability, rapid eye movements, changes in muscle reflexes, ataxia, dystonia, hallucinations, stupor and coma. Other effects have included nausea, vomiting, tachycardia, irregular heartbeat, seizures, respiratory depression and death."
Perrigo has included the labels and batch numbers corresponding with potentially defective dosing cups in the release.
