I was prescribed 500mg of cephalexin 4x a day for 7 days for a UTI. I experienced dizziness, nausea, tiredness and frequent urination while taking cephalexin. It’s been 10 days since I finished the antibiotics and I have been experiencing back pain and frequent urination. Every 15 minutes I have to pee!!! Is this normal, and how long does it take to get cephalexin out of your system?
