A member asked:
Can i take nyquil together with 400 mg guaifenesin?
3 doctors weighed in across 2 answers
Should be okay: Again, just make sure to not take a version of nyquil with Guaifenesin already in it and overdose on the guaifenesin.

Yes: While nyquil has a cough suppressant (anti-tussive) and Guaifenesin is an expectorant- to loosten phlegm and mucous in the lungs, they can be taken together without problem and are often combined in cough products. 100 mg of Guaifenesin is a sub-therapeutic dose- probably should have 4-600 mg in order to improve effectiveness.

Can you take Mucinex (guaifenesin) (expectorant) and sudafed together and will it keep you up at night. Or will nyquil be better for stuffy nose and mucus in throat?
