This medication is widely distributed in tissues and body fluids. Plasma protein binding is 80-95%. T1/2 is 12-22 h.

Due to suppression of intestinal microflora Doxycycline reduces prothrombin index which requires dose adjustment of indirect anticoagulants.

Doxycycline reduces the reliability of contraception and increases the frequency of breakthrough bleeding while taking estrogen-containing oral contraceptives.

Simultaneous administration of Doxycycline with:

  • barbiturates, carbamazepine, phenytoin concentrations of Doxycycline in plasma decreases due to the induction of liver enzymes, which may be responsible for the decrease of its antibacterial action.
