Does Zyban Interfere With Asthma Medications And Anti Depressants?

hi I want to stop smoking and I have taken Zyban in the past but after a few years went by I developed asthma I take Advair and Combivent and I also take a depressant called Citalopram 20mg. I want to get back to taking Zyban again because that seemed to have worked. But I wanted to know if there will be any side affects since I take all these medications
