Yes but unnecessary: There are few bacteria (in the sinus or anywhere else) treated with amoxicillin that are not equally well treated with sulfa-trimethoprim (Bactrim). And taking both will increase the risk of side effects, especially diarrhea or other gastrointestinal symptoms. Probably OK to stop the amoxicillin, but first check with your doctor.
