Doxycycline

No Prescription

Doxycycline is a broad-spectrum tetracycline antibiotic prescribed against a wide variety of bacterial infections, including Rocky Mountain spotted fever and other fevers caused by ticks, fleas, and lice; urinary tract infections; trachoma (chronic infections of the eye); and some gonococcal infections in adults. It is an approved treatment for inhalational anthrax. It is also prescribed with other medications to treat severe acne and amoebic dysentery (diarrhea caused by severe parasitic infection of the intestines).

Doxycycline may also be taken for the prevention of malaria on foreign trips of less than 4 months' duration.

Occasionally doctors prescribe Doxycycline to treat early Lyme disease and to prevent "traveler's diarrhea." These are not yet officially approved uses for this drug.
