Hey I have been on long term Bactrim (years) for acne (alergic to other antibiotics) and have taken every supplement under the sun with no problems. With that said make sure that no supplement you are taking will contribute to the underlying problem (staph growth) or else you may counteract some of the effect of the Bactirm (I think some aas, ps, ph, etc can contribute to accellerated growth of bacteria).
