I have been diagnosed as stongly suspicious for Rocky Mountain spotted fever. Definitely had a tick bite. I am female, 54, in good health otherwise. No chronic meds. I started doxycycline 100 mg q12h within 8 hrs of the initial symptoms- which included fever of 102, nausea, diarrhea, severe muscle pain, headache and fatigue. The rash developed on the third day starting on the legs and arms and has progressed to the trunk. Symptoms are all but gone with the exception of the rash and a little fatigue and slight headache. The rash has progressed from flat red spots to raised red bumps. It is not as severe as many of the pictures I have seen on line. My question: how long should I continue the doxy and how long before the rash disappears?
Thank you for your time.

Hello-

We usually treat RMSF with doxycycline for 7 days ( or at least 2 days after fevers resolved).

Rash may take a week or two to go away. One thing I cannot know for sure is if the rash you describe is from your infection- or a possible drug allergic reaction- It is not clear if you had the rash before you started the doxycycline- If this is not the case, and the rash only started when you took the medication, and it keeps worsening, I would suggest seeing your doctor again as he may stop or change antibiotics.

Good luck.

Always ask if you need clarification/more information.

Thank you to the Physician who answered my question today. The answer was far more informative than what I got from the Physicians I saw in person for my problem.
