I Am Currently Having Trouble With Cough Tics. This Started

I am currently having trouble with cough tics. This started with productive cough with yellow greensputum 6 days ago, after a day I lost my voice which persists for 3 days, now I have my voice back but still have hoarseness. Started with cefexime 200 mg every 12 hrs on the second day of productive yellowish sputum. now i am on the 4th day and noticed that my sputum has cleared and became whitish to clear in color since yesterday. i did not have any episodes of fever. But i am really quite troubled with persistent coughing. Most of the time it's dry cough. It is like my throat has become hypersensitive to any mucus even i lf there's really none there. Does my antibiotic have any side effects like this? I also take cetirizine at night to reduce waking episodes due to dry cough but it is still causing me trouble.
