Treatments and drugs

By Mayo Clinic Staff

If your doctor suspects that you have ehrlichiosis or another tick-borne illness, you'll likely receive a prescription for the antibiotic doxycycline (Doryx, Periostat, others). You'll generally take the antibiotic for seven to 10 days and should see signs and symptoms begin to subside within two days. Your doctor may have you take antibiotics for a longer period if you're severely ill.

If you're pregnant, your doctor may prescribe the antibiotic rifampin (Rifadin, Rimactane) instead, because doxycycline isn't recommended during pregnancy.
