Can Sular produce an adverse reaction of a cough?

For two weeks, since taking this medication I have a tickle in my throat producing a cough which produces a clear but thick mucus. It is not congestion in my chest. Does this drug have Sulfa in it?

I am allergic to Sulfa, so if it contains it, would that cause the uncontrollable cough, causing me to change how I sleep, sitting up in bed with 2-3 pillows to lessen the coughing. Thanks for your response.
