I stopped taking my Bactrim last night after a trip to the emergency room. From the first day of taking it for bronchitis, I started having headaches, pain behind my eyes and could not sleep well. On my sixth day of the medication, I started feeling dizzy and nauseated constantly. By day seven I was running fever of 101 and that evening, broke out into a rash from head to toes. My skin was itchy and tingling and it was getting difficult to breath. I immediately went to the ER. They have me taking Benadryl 3 times a day for 3 days until the rash clears up. I am not a fan of this medication….and I still have bronchitis!!
