My son just got off of two weeks of IV antibiotics (Zosyn and Vancomycin) and has just been switched to Bactrim (800-160) and Avelox (400mg) for another two weeks. He also recently started taking 1000 mg of Depakote (at the same time he was switched to the oral antibiotics). He has a 102 fever, chills and is now vomiting. What drug is causing these side effects and should he continue taking them? I have a call in to his doctor but would appreciate any help you could give me.
