Inform your doctor: Of these symptoms. The symptoms may be a result of the underlying illness for which you are taking the z-pak. But let your doctor know.

Could be...: But very seldom this may happen. Probably the real cause is the "side effect" of your own illness for which you are taking zithromycin.
