What this medicine is used for
Infections caused by the following micro-organisms: 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); Chlamydia trachomatis (lymphogranuloma venereum, trachoma, inclusion conjunctivitis). (Doxycycline is indicated in the treatment of trachoma, although the infectious agent is not always elminated, as judged by immunofluorescence. Inclusion conjunctivitis may be treated with oral doxycycline, or in combination with topical agents.) Borreliae (relapsing fever); Calymmatobacterium (Donovania) granulomatis (granuloma inguinale). DOXYCYCLINE SANDOZ is indicated for the treatment of Anthrax due to Bacillus anthracis, including inhalational anthrax (post-exposure) to reduce the incidence or progression of disease following exposure to aerosolized Bacillus anthracis (see Dosage and Administration). Infections caused by the following Gram-negative micro-organisms: Vibrio sp. (cholera); Brucella sp. (brucellosis; in conjunction with streptomycin); Yersinia pestis (plague); Francisella tularensis (tularaemia); Bartonella bacilliformis (bartonellosis); Bacteriodes sp. When penicillin is contraindicated, doxycycline is an alternative medicine in the treatment of infections due to: Treponema pallidum (syphilis); Treponema pertenue (yaws); Neisseria gonorrhoea (see Dosage and Administration). Note: DOXYCYCLINE SANDOZ is not the medicine of choice in the treatment of any type of staphylococcal infection or infections caused by Streptococcus pneumoniae, Haemophilus influenzae, Streptococcus pyogenes, Streptococcus faecalis or any type of enteric bacteria because many strains of these organisms have been shown to be resistant to doxycycline. DOXYCYCLINE SANDOZ should not be used in these infections unless the organism has been shown to be sensitive. For upper respiratory infections due to group A beta-haemolytic streptococci (including prophylaxis of rheumatic fever), penicillin is the usual medicine of choice. In acute intestinal amoebiasis DOXYCYCLINE SANDOZ may be a useful adjunct to amoebicides. In severe acne doxycycline may be a useful adjunctive therapy. 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 Plasmodium vivax. As there are relatively few locations where P. vivax does not coexist to some extent with P. falciparum, it is recommended that doxycycline should be used routinely with other agents, for example chloroquine.
