I was prescribed Levaquin for a sinus infection. Started taking the 500 mg. tablet on Thursday. Within 24 hours of the first dose, my sinus symptoms started feeling better, but I had wild dreams along with difficulty in sleeping, accompanied by bouts of sweating, then chilling. Friday nt. the diaharrea started and continued every 30 min. This was accompanied by severe abdominal pain and weakness. I have stopped taking this drug, only took 3 pills, but the diaharrea continues. Has anyone else had this awful side effect, and if so....how long did it last after discontinuing the medication. I, like many others have posted, will NEVER take this medication again, nor will I let it be prescribed to any family member!
