Do Antibiotics really reduce your blood volume?

Many times I meet patients who insist on a blood tonic to go with their antibiotics because they believe that antibiotics dry up the blood or causes blood thinning.

How true is this?

As a matter of fact, many of the antibiotics we have around have no negative effect on blood volume, the very few that do reduce blood volume are prescribed less commonly and with caution.

Blood tonics however decrease the absorption of some antibiotics such as:

  • Tetracycline and tetracycline derivatives like doxycycline
  • Quinolones like ciprofloxacin and levofloxacin

Thus, if you insist on taking iron or blood tonic with your antibiotics, it is best to take them at least 2 hours before or 2 hours after taking your antibiotics.
