The eilimination half life of doxycycline is between 16 to 22 hours (for healthy adults).
It takes 5.5 x elimination half life (hours) before a drug is completely cleared from your system.
So if we take the maximum elimination half life of 22 hours, it would take 121 hours i.e. approximately 5 days (5.5 x 22 hours) before the medicine is eliminated from your system.
