Does Z Pack Counter The Effects Of Loestrin?

I am on Lo Loestrin, I had unprotected sex and I am on the z pack for a sinus infection. I know some antibiotics effect Lo Loestrin's effectivness but the pharmasist says that I shouldnt be worried about using back up with the z pack. Should i be worried?
