I'm really concerned because my cough hasn't improved since Tuesday, even though I've been taking Zecuf and levocet. Is there something else I should be doing, or could it be something more serious?
You seem to be suffering from viral upper respiratory tract infection which is a common type of throat infection. You may need continue taking medication as recovery may take up to a week. Steam inhalation is also beneficial
