Having had MRSA before my surgeon has put me on clindamycin 3 days prior to explant surgery. Is that standard procedure?

I contracted MRSA from tummy tuck & implant surgery in 2011. I now have to have the implants taken out due to capsular cotracture. I am TERRIFIED that the MRSA will return with this surgery. My surgeon is putting me on clindamycin 3 days prior to surgery & I will be on it for 10 days total. Is that a standard procedure for someone with my history? Are there any other precautions that should be taken? I am 54 & in good health otherwise.
