Response And Effectiveness

The next thing to know about Doxycycline is its response and effectiveness.

• The oral administration of doxycycline results in practically full absorption. Two to three hours after dose, peak concentrations are reached; however, it could take up to 48 hours before infection-related symptoms start to subside.
• The liver concentrates doxycycline in the bile, which is then eliminated in an active form through the urine and feces.
