sore throat when on antibiotic?

[DianeWare]

I am taking bactrim for a UTI. I also have a sore throat. No scratchiness or raw feeling. It just hurts to swallow. (Like when a piece of potato chip gets stuck going down.) Doctor yesterday took a swab but said bactrim doesn't work for upper respiratory infections. However, she didn't give me an other antibiotic. I don't have fever. But she said the bactrim may be preventing me from having fever. When I looked on line, it said that bactrim is prescribed for upper respiratory. Does that mean that my sore throat is viral? I really need to get this cleared up because I am going to see my pregnant daughter on Friday.

Hi DianeWare,
Actually, a side effect of bacterim is sore throat. So it could be that, and you may want to tell your doctor about it.  If it isn't a side effect then it may be a virus. I don't think it is a secondary bacterial infection. Usually you would have a high fever, pus in the throat etc. if it was a strep throat. Bacterim has limited activity and works on lower respiratory tract (pneumonia) organisms and not generally streptococci. It is more effective towards other bacteria. So, i don't think you have a strep throat.

did you do urine culture before taking antibiotics? UTI could be a secondary infection triggered by another infection, maybe viral, that is challenging your immune system.
