I am an asthmatic and i have a productive cough for 3 days already. what's the best otc cough med for me? are mucolytics not good for asthmatics?

Fine: Mucolytics are okay, but the question is, how much are you using your inhalers and does the cough represent out of control constriction of your breathing passages? 3 days is enough. Get checked. Waiting too long to figure out what is happening can be dangerous, if you know what i mean. Very dangerous. Just have it checked out. Your medication may need to be adjusted. All the best.
