Are antibiotics malabsorbed like vitamins?

I have had a history of serious cellulitis infections in my leg (at times requiring 1-2 weeks of hospitalizations with i-v antibiotics). At 11 weeks post-op, I had another infection crop up. I called the doctor's office and they immediately put me on Keflex, 500 mg. twice a day. The first day or two of the infection, I didn't think I was responding well to the antibiotics--although after about 4 days, it's much better. Does anyone know whether antibiotics are malabsorbed after lap RNY, as vitamins are? I am wondering whether now I'll need a stronger dose of drugs to have the same effect as before surgery? Thanks for the input!
