Indicated as adjunctive therapy for acute intestinal amebiasis

Indicated as adjunctive therapy for severe acne

Indicated for treatment of only inflammatory lesions (papules and pustules) of rosacea in adults

Use of tetracyclines during tooth development (last half of pregnancy through age 8 years) can cause permanent discoloration of teeth; this adverse reaction is more common during long-term use but 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 potential benefits expected to outweigh risks in severe or life-threatening conditions (eg, 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, and may range in severity from mild diarrhea to fatal colitis

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

May result in overgrowth of non-susceptible organisms, including fungi. If such infections occur, discontinue use and institute appropriate therapy

Severe skin reactions, such as exfoliative dermatitis, erythema multiforme, Stevens-Johnson syndrome, toxic epidermal necrolysis, and drug reaction with eosinophilia and systemic symptoms (DRESS) reported; if severe skin reactions occur, discontinue therapy immediately and institute appropriate therapy

Intracranial hypertension (pseudotumor cerebri) reported (rare) may occur; symptoms include headache, blurred vision, diplopia, and vision loss; papilledema can be found on funduscopy; women of childbearing age who are overweight or have a history of IH are at greater risk; possibility for permanent visual loss exists; if visual disturbance occurs during treatment, prompt ophthalmologic evaluation is warranted; intracranial pressure can remain elevated for weeks after drug cessation; monitor until they stabilize

All tetracyclines form a stable calcium complex in any bone-forming tissue; decrease in fibula growth rate has been observed in prematures given an oral tetracycline; reaction was shown to be reversible when the drug was discontinue

Antianabolic action of the tetracyclines may cause an increase in BUN; studies to date indicate that this does not occur with the use of doxycycline in patients with impaired renal function

Doxycycline offers substantial but not complete suppression of the asexual blood stages of Plasmodium strains

Prescribing doxycycline in the absence of a proven or strongly suspected bacterial infection or a prophylactic indication is unlikely to provide benefit to the patient and increases the risk of the development of drug-resistant bacteria

In long-term therapy, periodic laboratory evaluation of organ systems, including hematopoietic, perform renal and hepatic studies

Therapy may cause discoloration deciduous teeth, and reversible inhibition of bone growth when administered during second and third trimester of pregnancy, infancy, and childhood

Based on available published data, doxycycline is present in human milk; there are no data that inform about levels of doxycycline in breastmilk, effects on breastfed infant, or on milk production
