Can I take tyl cold and flu elix with mucinex (guaifenesin)?

Read ingredients. Mucinex (guaifenesin) is Guaifenesin which loosens your secretion. Your tylenol cold likely has Diphenhydramine and acetaminophen. Your flu elixir may have the same and you may get too sleepy with these meds combined. Read the ingredients so as not to take too much of each type of medicine.
