Rocky Mountain spotted fever

  • Alternative Names

    Spotted fever


    Treatment involves careful removal of the tick from the skin and antibiotics to eliminate the infection. Doxycycline or tetracycline are frequently used for both confirmed and suspected cases. Chloramphenicol may be used in pregnant women.

    Note: There is concern that tetracycline and doxycycline may stain the teeth of children whose permanent teeth have not yet formed. Tooth discoloration, however, is very unusual when a child takes these medicines for 14 days or less. Therefore these medicines are first line treatment, even for children.
