Talk to Pulmonologist / Lung on Shortness Of Breath

Assalam-o-alaikum. I had a sore throat two weeks ago. I took antibiotic Claritek 250 mg twice a day as prescribed by the ENT. As soon as I took the dose of medicine, I started to have shortness of breath. It happend throughout the day. Then it didn't occur till next four days. On the fifth day, I again started feeling shortness of breath and it continues from then to one week. It is mild. But it now it occurs everyday usually while eating. At night, i am not able to sleep for consecutive hours. I have been suffering from shortness of breath since one week. Is this a side effect of antibiotic?
