Vitamin K
Supplementation Possibly Helpful
Like all other antibiotics, cephalosporins might interfere with vitamin K levels by killing vitamin K–producing bacteria in the intestines. In addition, antibiotics in the cephalosporin family may also interfere with the way vitamin K works.1 For this reason, taking extra vitamin K may be a good idea when using cephalosporins over the long term.
