bacterial infection
"I was prescribed this generic for a raging infection contracted when I had a small surgical procedure done on my finger.  Within 24 hours of the procedure, my finger was inflamed and throbbing.  Keeflex was first prescribed and another 24 hours later was determined it had not touched the infection.  So, I was given Zyvox.  It totally eradicated the germ I had contracted.  I did have some bothersome side effects, mostly with my stomach just not feeling right.  Later in the second week, my tongue turned brown, but no other problems.  I was very tired most of the time, and could not decide if it was the med or the infection."
