Doxycycline is bacteriostatic unless given in high doses. If high blood levels are not attained,
treatment failures in early and late disease are common. However, these high doses can be difficult to tolerate.

For example, doxycycline can be very effective but only if adequate blood levels are achieved either by high
oral doses (300 to 600 mg daily)

Treatment for: Borrelia burgdorferi (Lyme Disease)

Dosage: 300-600 MG
