Guaifenex Dry Nasal Passages, Sinus Infection, Pain in My Head, Light Headedness, Lathargic
I was prescribed this in conjunction with Biaxin for a sinus infection. I have more pain in my head, headaches, light headedness, nausea, and a very lathargic feeling. I also have extremely dry nasal passages. After reading the previous entries I am going to stop taking it. It can't hurt.
