Cephalexin
bladder infection
"The first day I took it my skin felt flushed and I had a bad headache and dizziness (almost chickened out then). But these effects improved as I continued to take the medicine. I was prescribed 500mg three times a day for 5 days for trace leukocytes in my urine. I've never taken cephalexin before, and I'm very sensitive to medications (slow metabolizer) and already cannot take several antibiotics due to allergies (cipro, nitrofuratoin and sulfa). So I'm thankful that I seem to be okay with the cephalexin (I'm running out of antibiotics that I can take!). I haven't noticed any other side effects, not even diarrhea. As for my symptoms, some have improved but not all. I only have 2 pills left but not all of my symptoms went away yet. I hope it works."
