Approved Uses

To reduce the development of drug-resistant bacteria and maintain the effectiveness of Vibramycin and other antibacterial drugs, Vibramycin should be used only to treat or prevent infections that are proven or strongly suspected to be caused by susceptible bacteria.

Doxycycline is indicated for the treatment of the following infections:

  • Rocky Mountain spotted fever, typhus fever and the typhus group, Q fever, rickettsialpox, and tick fevers caused by Rickettsiae
  • Respiratory tract infections caused by Mycoplasma pneumoniae
  • Lymphogranuloma venereum caused by Chlamydia trachomatis
  • Psittacosis (ornithosis) caused by Chlamydia psittaci
  • Trachoma caused by Chlamydia trachomatis, although the infectious agent is not always eliminated, as judged by immunofluorescence
  • Inclusion conjunctivitis caused by Chlamydia trachomatis
  • Uncomplicated urethral, endocervical, or rectal infections in adults caused by Chlamydia trachomatis
  • Nongonococcal urethritis caused by Ureaplasma urealyticum
  • Relapsing fever due to Borrelia recurrentis

Doxycycline is also indicated for the treatment of infections caused by the following gram-negative microorganisms:

  • Chancroid caused by Haemophilus ducreyi
  • Plague due to Yersinia pestis
  • Tularemia due to Francisella tularensis
  • Cholera caused by Vibrio cholerae
  • Campylobacter fetus infections caused by Campylobacter fetus
  • Brucellosis due to Brucella species (in conjunction with streptomycin)
  • Bartonellosis due to Bartonella bacilliformis
  • Granuloma inguinale caused by Klebsiella granulomatis

Doxycycline is indicated for treatment of infections caused by the following gram-negative microorganisms, when bacteriologic testing indicates appropriate susceptibility to the drug:

  • Escherichia coli
  • Enterobacter aerogenes
  • Shigella species
  • Acinetobacter species
  • Respiratory tract infections caused by Haemophilus influenzae
  • Respiratory tract and urinary tract infections caused by Klebsiella species

Doxycycline is indicated for treatment of infections caused by the following gram-positive microorganisms when bacteriologic testing indicates appropriate susceptibility to the drug:

  • Upper respiratory infections caused by Streptococcus pneumoniae
  • Anthrax due to Bacillus anthracis, including inhalational anthrax (post-exposure): to reduce the incidence or progression of disease following exposure to aerosolized Bacillus anthracis

When penicillin is contraindicated, doxycycline is an alternative drug in the treatment of the following infections:

  • Uncomplicated gonorrhea caused by Neisseria gonorrhoeae
  • Syphilis caused by Treponema pallidum
  • Yaws caused by Treponema pallidum subspecies pertenue
  • Listeriosis due to Listeria monocytogenes
  • Vincent’s infection caused by Fusobacterium fusiforme
  • Actinomycosis caused by Actinomyces israelii
  • Infections caused by Clostridium species

In acute intestinal amebiasis, doxycycline may be a useful adjunct to amebicides.

In severe acne, doxycycline may be useful adjunctive therapy.

Prophylaxis:

• Doxycycline is indicated for the prophylaxis of malaria due to Plasmodium falciparum in short-term travelers (less than 4 months) to areas with chloroquine and/or pyrimethamine-sulfadoxine resistant strains.

The use of drugs of the tetracycline class during tooth development (last half of pregnancy, infancy and childhood to the age of 8 years) may cause permanent discoloration of the teeth (yellow-gray-brown).This adverse reaction is more common during long-term use of the drugs, but it has been observed following repeated short-term courses. Enamel hypoplasia has also been reported. Use doxycycline in pediatric patients 8 years of age or less only when the potential benefits are expected to outweigh the risks in severe or life-threatening conditions (e.g., anthrax, Rocky Mountain spotted fever), particularly when there are no alternative therapies.

Clostridium difficile associated diarrhea (CDAD) has been reported with use of nearly all antibacterial agents, including Vibramycin, and may range in severity from mild diarrhea to fatal colitis. Treatment with antibacterial agents alters the normal flora of the colon leading to overgrowth of C. difficile.

Intracranial hypertension (IH, pseudotumor cerebri) has been associated with the use of tetracyclines including Vibramycin.

A decrease in fibula growth rate has been observed in prematures given oral tetracycline in doses of 25 mg/kg every 6 hours. This reaction was shown to be reversible when the drug was discontinued.

Photosensitivity manifested by an exaggerated sunburn reaction has been observed in some individuals taking tetracyclines.

Severe skin reactions, such as exfoliative dermatitis, erythema multiforme, Stevens Johnson syndrome, toxic epidermal necrolysis, and drug reaction with eosinophilia and systemic symptoms (DRESS) have been reported in patients receiving doxycycline.

Vibramycin Syrup contains sodium metabisulfite, a sulfite that may cause allergic-type reactions, including anaphylactic symptoms and life-threatening or less severe asthmatic episodes in certain susceptible people.

Absorption of tetracyclines is impaired by antacids containing aluminum, calcium, or magnesium, and iron-containing preparations.

Absorption of tetracyclines is impaired by bismuth subsalicylate.

Barbiturates, carbamazepine, and phenytoin decrease the half-life of doxycycline.

Concurrent use of tetracycline may render oral contraceptives less effective.

Because tetracyclines have been shown to depress plasma prothrombin activity, patients who are on anticoagulant therapy may require downward adjustment of their anticoagulant dosage.

Since bacteriostatic drugs may interfere with the bactericidal action of penicillin, it is advisable to avoid giving tetracyclines in conjunction with penicillin.

The concurrent use of tetracycline and Penthrane (methoxyflurane) has been reported to result in fatal renal toxicity.

False elevations of urinary catecholamine levels may occur due to interference with the fluorescence test.

Results of animal studies indicate that tetracyclines cross the placenta, are found in fetal tissues, and can have toxic effects on the developing fetus (often related to retardation of skeletal development). Evidence of embryotoxicity has also been noted in animals treated early in pregnancy. If any tetracycline is used during pregnancy or if the patient becomes pregnant while taking this drug, the patient should be apprised of the potential hazard to the fetus.

Tetracyclines are excreted in human milk. Because of the potential for serious adverse reactions in nursing infants from doxycycline, a decision should be made whether to discontinue nursing or to discontinue the drug, taking into account the importance of the drug to the mother.
