My wife has a UTI, diagnosed yesterday, and today the Urgent care person called to change the prescription to Cefuroxime 200 mg, 2x day for 5 days. However, this evening the urge to urinate has returned and even after taking some AZO tablets this evening,, she is concerned her urine is not changing color. Her blood pressure has increased to 180/105 and she is quite anxious. Any advise?
