No, and why are you: asking? If you are trying to OD, you need to contact your doctor immediately, call a suicide hotline and get help. Mucinex (guaifenesin) itself is just guanifenisin, which doesn't really have any toxicity even in high doses. However, there are versions of the medication that have antihistamines, decongestants and dextromethorphan, and all of these in higher doses can cause problems, although rarely serious.
