Will Bactrim (sulfamethoxazole and trimethoprim) help with my cough and sore throat, I am coughing up Green Mucus?

.... you need to first follow up with a healthcare provider to determine why you are coughing. if pneumonia, bactrim (sulfamethoxazole and trimethoprim) is not the best coverage.
Maybe maybe not. Bactrim (sulfamethoxazole and trimethoprim) is an antibiotic used to treat usually urine infections or skin infections. While it may be used to treat a cough/sore throat, it is probably not the best option. Best to see your doctor to see if there is something else he or she would suggest instead. Feel better!
