Zpak done, not any better, humidifier too, mucinex still hard to breathe n cough still rough. ?

? to early ?: The benefit of the Zpac is it doesn't take long to complete but it remains in your body working for at least a week after you stop. You can retain a symptomatic cough with bronchitis for up to a month after starting treatment. Mucinex can help loosen secretions. If you are concerned that your symptoms are getting progressively worse contact the treating doc.
