Generic Name: Demeclocycline (DEM-e-kloe-SYE-kleen)Brand Name: Declomycin

Demeclocycline is used for:

Treating certain bacterial infections. It may be used in combination with other medicines to treat amoeba infections in the intestines. It may also be used for other conditions as determined by your doctor.

Demeclocycline is a tetracycline antibiotic. It works by interfering with the production of proteins needed by the bacteria to grow. Slowing the bacteria's growth allows the body's defense mechanisms (eg, white blood cells) to destroy the bacteria.

Do NOT use Demeclocycline if:

  • you are allergic to any ingredient in Demeclocycline or another tetracycline (eg, minocycline)
  • you are taking acitretin, isotretinoin, or a penicillin (eg, amoxicillin)

Contact your doctor or health care provider right away if any of these apply to you.

  • if you are taking any prescription or nonprescription medicine, herbal preparation, or dietary supplement
  • if you have allergies to medicines, foods, or other substances
  • if you have kidney or liver problems or diabetes
