Too much Rx: I wouldn't mix the codeine containing cough medicine with Mucinex (guaifenesin) DM which contains dextromethorphan. The dextromethorphan is basically an analog of a narcotic and you would be getting an excessive dose of narcotic which could cause excessive sedation, respiratory supression, nausea, vomiting, dizziness, and other adverse effects.
