Anyone can develop an allergy at any time. Many are allergic to sulfa, the main ingredient in Bactrim and Septra. I didn't think fever was a symptom of allergy, but it might be. You probably should let the doctor who prescribed the Bactrim know about her reaction. It may be a sign that she shouldn't take it anymore. Some allergies get much worse each time you have a reaction. Some happen after an accumulation of the substance the person is allergic to. Definitely watch her very closely. If there is anymore swelling of the throat, mouth, tongue, or if she is having a hard time breathing, she may need to go to the ER.
