Doxycycline hyclate is prescribed to treat bacterial infections caused by flea and tick bites, deer flies, and exposure to Anthrax and plague, advises WebMD. Infections caused by Rocky Mountain Spotted Fever are also treated with doxycycline hyclate, as are infections caused by the chlamydiae species bacteria, certain highly infectious venereal diseases, and the actinomyces bacteria.

A doctor may also prescribe doxycycline hyclate if a patient has an infection caused by the microorganism coxiella burnetii or rickettsia tsutsugamushi, notes WebMD. Doxycycline hyclate is also used as a preventive medication for Lyme disease.

Doxycycline hyclate only treats bacterial infections. It is not used to combat the flu, the common cold or other viral infections, explains WebMD. When used inappropriately or unnecessarily, the medication's effectiveness may diminish. It is important to only use doxycycline hyclate to treat the condition it was prescribed to treat, and to follow the doctor's instructions implicitly.

Common side effects of doxycycline hyclate include nausea, diarrhea and vomiting, states WebMD. Patients should notify the doctor immediately if symptoms worsen or persist. More serious side effects that require immediate medical attention include a change in the amount of urine discharged, pain and difficulty in swallowing, sun sensitivity and pressure inside the skull.
