Query fever

The main treatment for Q fever is with antibiotics. For early-stage (acute) Q fever, doxycycline is the recommended antibiotic.

For chronic Q fever, a combination of doxycycline and hydroxychloroquine is often used. You may need to take antibiotics for several months.

The outlook for people who get treated in the early stages of Q fever is generally good.

Chronic Q fever requires long-term treatment with antibiotics. Your health care provider should check you often to make sure the disease has not returned.
