Has anyone experienced any side effects while using Aczone and/or Atralin? I've been having some symptoms but I'm not sure if they are drug related or just sinus/cold related. I've been using the topicals for 6 weeks now and last week I began having bone aches/chills, slight fever, tiredness, sore throat, back tightness, and for a couple of days a strong urine smell. Those seem to have subsided but now I have a persistent headache (I never get headaches) and a dry cough. ## Have you talked to your doctor? Since they are both topical formulations, you really shouldn't absorb enough of the relevant medications to cause such severe side effects. This makes me suspect that they were probably more related to the cold/sinus issues. How are the headaches, have they improved any...
