What this medicine is used for

(ARTG)

Doxycycline is indicated in the treatment of infections caused by the following microorganisms: Mycoplasma pneumoniae: primary atypical pneumonia; Rickettsiae: Queensland tick typhus, epidemic typhus fever, Q fever, murine endemic typhus fever, Australo-Pacific endemic scrub typhus; Chlamydia psittaci: psittacosis; Calymmatobacterium (Donovania) granulomatis: granuloma inguinale; Chlamydia trachomatis: lymphogranuloma venereum, trachoma, inclusion conjunctivitis (Doxycycline is indicated in the treatment of trachoma, although the infectious agent is not always eliminated, as judged by immunofluorescence. Inclusion conjunctivitis may be treated with oral doxycycline alone or in combination with topical agents.); Doxycycline is indicated in the treatment of infections caused by the following Gram-negative microorganisms: Vibrio species: Cholera; Brucella species: Brucellosis (in conjunction with streptomycin); Yersinia pestis: plague; Francisella tularensis: tularaemia; Bartonella bacilliformis: Bartonellosis; Bacteroides species. Doxycycline is active against both pre-erythrocytic and asexual bloodstages of Plasmodium falciparum. The tetracyclines are only partially active against the pre-erythrocytic stages of Plasmodium vivax, and protection depends on drug suppression of the blood stages. Doxycycline has no activity against the relapsing forms (hypnozoites) of Plasmodium vivax. Doxycycline is indicated, in adults and children older than 10 years, as chemoprophylaxis for malaria caused by Plasmodium falciparum and, in combination with other antimalarial agents, against malaria caused by Plasmodium vivax. Doxycycline is only able to suppress malaria caused by P.vivax. As there are relatively few locations where P.vivax does not co-exist to some extent with P.falciparum, it is recommended that doxycycline should be used routinely with other agents, eg. chloroquine. When penicillin is contraindicated, doxycycline is an alternative drug in the treatment of infections due to: Treponema pallidum: syphilis; Treponema pertenue: yaws; Neisseria gonorrhoeae: gonorrhoea. Doxycycline may be a useful adjunct to amoebicides in the treatment of acute intestinal amoebiasis. In the treatment of severe acne, doxycycline may be a useful adjunctive therapy. Doxycycline is not the drug of choice in the following: Any type of staphylococcal infection or infections caused by Streptococcus pneumoniae, Haemophilus influenzae, Streptococcus pyogenes, Enterococcus faecalis, or any type of enteric bacteria because many strains of these organisms have been shown to be resistant to doxycycline. Doxylin should not be used for these infections unless the organism has been shown to be sensitive. For upper respiratory infections due to group A B-haemolytic streptococci, (including prophylaxis of rheumatic fever), penicillin is the usual drug of choice.
