Does Bactrim cause drowsiness?
That’s not one of the typical side effects. Drowsiness is a sign of an overdose in some cases when taking Bactrim. I would recommend talking to your doctor about it and see what he or she thinks or even your pharmacy. I have heard of people having drowsiness while taking Bactrim but not to the extent that you experience. So ask a professional. Hope this helps. Good Luck!
