Lyme Disease must be diagnosed in its early stages and treated for up to 28 days with doxycycline, or it is possible that the doxycycline treatment will not work effectively. In this case, doctors can use an intravenous treatment of Ceftriaxone or penicillin. A second four-week course of doxycycline can be tried, but nothing longer will be beneficial.
