Cephalosporins

Vitamin K - Supplementation Possibly Helpful




See also Antibiotics (General)

These antibiotics work somewhat similarly to penicillin, but have been chemically modified to have a broader spectrum of effect.

Drugs in this family include

  • cefadroxil (Duricef)
  • cephalexin (Cefanex, Keflex, Keftab, Biocef)
  • cephradine (Velosef)
  • cefaclor (Ceclor, Ceclor CD)
  • cefprozil (Cefzil)
  • cefuroxime (Ceftin)
  • loracarbef (Lorabid)
  • cefdinir (Omnicef)
  • cefixime (Suprax)
  • cefpodoxime proxetil (Vantin)
  • ceftibuten (Cedax)
  • and others
 

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.
