Brand name: Doxsig TM

Active ingredients: doxycycline

What it is used for

Infections caused by the following 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 eliminated, as judged by immunofluorescence. Inclusion conjunctivitis may be treated with oral doxycycline alone, or in combination with topical agents). Borreliae (relapsing fever). Calymmatobacterium (Donovania) granulomatis (granuloma inguinale). Infection caused by the following Gram-negative microorganisms: Vibrio species (chlorea), Brucella sp. (Brucellosis; in conjunction with streptomycin), Haemophilus ducreyi (chancroid), Yersinia pestis (plague), Francisella turarenis (tularaemia), Bartonella bacilliformis (Bartonellosis), Bacteroides sp. When penicillin is contraindicated, Doxy-100 is an alternative drug in the treatment of infections due to : Treponema pallidum (syphilis); Treponema pertenue (yaws); Neisseria gonorrhoea (see Dosage and Administration). Doxy-100 is not the drug of choice in the treatment of any type of staphylococcal infection or infections due to 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. Doxy-100 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 drug of choice. In acute intestinal amoebiasis, doxycycline may be a useful adjunct to amoebicides. In severe acne, doxycycline may be 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 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, for example, chloroquine.
