[|Human|] I recently treated my cold and sinus sickness by taking advil cold & sinus, 2 tablets x 3 / day. However I continued to have an irritating and unproductive cough. I took klacid 500 twice a day for 1 week. When coughing the mucus was of white color. I was later told to take N-acetylcysteine 200 mg 3 times per day and I have been on it for 2 days without any noticeable difference. The irritating cough persists and when exhaling I can hear rippling sounds from my mouth as if coming from my upper chest.  Should I continue taking N-acetylcysteine and for how much longer?
[|AI|]  Hi, Since it has been more than a week that you have been having cough in spite of medications, I would suggest that you take a course of antibiotics, provided you are not allergic, and it is not contraindicated. Azithromycin 500 mg a day for 3 days would be a good choice. If you are having a nonproductive cough you would need to go for an expectorant syrup which should contain guaifenesin along with terbutaline and dextromethorphan. Please discuss this with your physician before starting or changing your medications.
