Treatment Patients suspected of having Rocky Mountain spotted fever should be treated immediately with general antibiotics. Two drugs that have been found effective against Rickettsia rickettsia are chloramphenicol and tetracycline. It is the drug of choice especially for cases in which meningococcemia could not be ruled out, in severe cases, and in pregnant women. Because of the drug's hematopoictic toxicity, the usual precautionary measures regarding chloramphenicol administration should be taken as directed by a physician. Patients should avoid milk and antacids during tetracycline administration.
Supportive care is as important as antibiotic therapy.
Attention should be given to correcting dehydration, electrolyte imbalance, oliguria, inadequate iiitravascular fluids, etc. Antibiotic therapy can be terminated two to four days after the patient's temperature returns to normal. The duration of therapy is usually seven to ten days. Continue here to read about RMSF and Ehrlichiosis in Dogs.
