    Doxycycline Prophylaxis for Preventing Lyme Disease after a Deer Tick Bite
    (2009-09-18) Kramer, Christina
    After a deer tick bite, one dose of the antibiotic, doxycycline, is effective in preventing Lyme disease. Doxycycline should be given if you have had a deer tick attached for 72 hours or more. If the tick has been attached for less time then doxycycline is not needed because it is very unlikely that the Lyme disease bacteria would have been transmitted to you. Doxycycline should only be given if it was a deer tick that bit you. For doxycycline to be effective, it should be given within 72 hours of removing the tick.
