I recently started on an antibiotic called avelox for the treatment of my sinus, throat and lung infection. Its my third day so far taking it , and my chest is super congested so purchased a benelyn extra strength mucus and phlem relief. I took it around 10 pm before bed and woke up at 1230 with a rapid heart beating, causing my head to spin and chest to hurt. It lasts for 6 hours I believe so all I can do is wait it out. But this is a scary situation.
