Treatments and drugs
By Mayo Clinic staffIf your doctor suspects that you have ehrlichiosis or another tick-borne illness, you'll likely receive a prescription for an antibiotic, such as doxycycline or tetracycline. You'll generally take the antibiotics 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 he or she believes you might be infected with Lyme disease as well.
If you're pregnant, your doctor may prescribe the antibiotic rifampin instead, because tetracycline and doxycycline aren't recommended during pregnancy.
