Can i take mucinex (guaifenesin) fast max on an empty stomach? i took it and ended up throwing up really bad. lots of reports on the internet of adverse effects of taking mucinex (guaifenesin) on empty stomach.

Mucinex (guaifenesin): mucinex (guaifenesin) is brand name for glycerol guiacolate Same as Robitussin but in pill form. It is an expectorant and loosens mucus so you can spit it up. You can also drink a lot of tea and do largely the same thing. Maybe you took it because you were coughing (appropriate) and because you coughed hard you set off the gag reflex and that's why you vomited badly. It wasn't the mucinex (guaifenesin) but the cough!

Yes like most: medications, empty stomach + pills = potential disaster. As a rule of thumb, I ask my patients to take most pills with something like a small piece of bread or rice to help soothe any irritation to the gastric lining -- as well as to increase the digestive process. Except for a few medicines (thyroid, anti-acid meds, nausea meds) you should remember that rule. Thanks for trusting in HealthTap.
