Use Doxycycline Hyclate Delayed-Release Tablets 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.
Clostridium Difficile Associated Diarrhea Clostridium difficile associated diarrhea CDAD has been reported with use of nearly all antibacterial agents, including Doxycycline Hyclate Delayed-Release Tablets, 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. Hypertoxin producing strains of C. CDAD must be considered in all patients who present with diarrhea following antibacterial use.
Careful medical history is necessary since CDAD has been reported to occur over two months after the administration of antibacterial agents. Appropriate fluid and electrolyte management, protein supplementation, antibacterial treatment of C.
Photosensitivity Photosensitivity manifested by an exaggerated sunburn reaction has been observed in some individuals taking tetracyclines. Patients apt to be exposed to direct sunlight or ultraviolet light should be advised that this reaction can occur with tetracycline drugs, and treatment should be discontinued at the first evidence of skin erythema. Superinfection As with other antibacterial preparations, use of Doxycycline Hyclate Delayed-Release Tablets may result in overgrowth of non-susceptible organisms, including fungi.
If superinfection occurs, the antibacterial should be discontinued and appropriate therapy instituted. Intracranial Hypertension Intracranial hypertension IH, pseudotumor cerebri has been associated with the use of tetracycline including Doxycycline Hyclate Delayed-Release Tablets. Clinical manifestations of IH include headache, blurred vision, diplopia , and vision loss; papilledema can be found on fundoscopy. Women of childbearing age who are overweight or have a history of IH are at greater risk for developing tetracycline associated IH.
Avoid concomitant use of isotretinoin and Doxycycline Hyclate Delayed-Release Tablets because isotretinoin is also known to cause pseudotumor cerebri. Although IH typically resolves after discontinuation of treatment, the possibility for permanent visual loss exists.
If visual disturbance occurs during treatment, prompt ophthalmologic evaluation is warranted. Since intracranial pressure can remain elevated for weeks after drug cessation patients should be monitored until they stabilize. Skeletal Development All tetracyclines form a stable calcium complex in any bone-forming tissue. This reaction was shown to be reversible when the drug was discontinued.
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 also has been noted in animals treated early in pregnancy. If any tetracycline is used during pregnancy or if the patient becomes pregnant while taking these drugs, the patient should be apprised of the potential hazard to the fetus.
Studies to date indicate that this does not occur with the use of doxycycline in patients with impaired renal function. Malaria Doxycycline offers substantial but not complete suppression of the asexual blood stages of Plasmodium strains.
