Cephalexin
"I had folliculitis. My Doctor prescribed to me 500 mg 4 times a day for ten days. I had to stop at day 6. I had diarrhea up to 5 times a day. Then I got a yeast infection on my penis right after I stopped taking cephalexin. Currently, I have candida overgrowth and it is not going away. I wished I never took this antibiotic... it does more harm than it does help."
