Can Mucinex be harmful to dogs?

Can Mucinex be harmful to dogs?

The pharmacokinetics of guaifenesin (Mucinex) haven't been thoroughly studied in dogs. To address your concerns as best as I can, please note that of the 64 dog oral exposures to guaifenesin reported to the ASPCA Animal Poison Control Center during 2005-2009 only 5 showed clinical signs. These dogs received a dosage estimated between 415 and 830 mg/kg (189 and 377 mg/lb) and exhibited hypothermia, mild tremors, ataxia ("drunken sailor"), and vomiting. No specific antidote is available and so treatment remains supportive only.

Please respond with further questions or concerns if you wish.
