Declomycin

Name: Declomycin

Why is this medication prescribed?

Demeclocycline is used to treat infections caused by bacteria includingpneumonia and other respiratory tract infections;; certain infections of the skin, eye, lymphatic, intestinal, genital, and urinary systems; and certain other infections that are spread by ticks, lice, mites, and infected animals. It is also used along with other medications to treat acne. Demeclocycline is also used to treat plague and tularemia (serious infections that may be spread on purpose as part of a bioterror attack). Demeclocycline can also be used in patients who cannot be treated with penicillin to treat certain types of food poisoning and anthrax (a very serious infection that may be spread on purpose as part of a bioterror attack), Demeclocycline is in a class of medications called tetracycline antibiotics. It works by preventing the growth and spread of bacteria.

Antibiotics such as demeclocycline will not work for colds, flu, or other viral infections. Using antibiotics when they are not needed increases your risk of getting an infection later that resists antibiotic treatment.

Other uses for this medicine

Demeclocycline is also sometimes used to treat syndrome of inappropriate antidiuretic hormone (SIADH; condition in which the body produces too much of a certain natural substance that causes the body to retain water). Talk to your doctor about the risks of using this medication for your condition.

This medication is sometimes prescribed for other uses; ask your doctor or pharmacist for more information.

What is the most important information I should know about Declomycin (demeclocycline)?

You should not take this medication if you are allergic to demeclocycline or to similar antibiotics such as doxycycline (Adoxa, Alodox, Avidoxy, Oraxyl, Doryx, Oracea, Vibramycin), minocycline (Dynacin, Minocin, Solodyn), or tetracycline (Ala-Tet, Brodspec, Panmycin, Sumycin, Tetracap).

Do not use demeclocycline if you are pregnant. It could harm the unborn baby or cause permanent tooth discoloration later in life.

Demeclocycline can make birth control pills less effective. Ask your doctor about using a non-hormone method of birth control (such as a condom, diaphragm, spermicide) to prevent pregnancy while taking demeclocycline.

Demeclocycline passes into breast milk and may affect bone and tooth development in a nursing baby. You should not breast-feed while you are taking demeclocycline.

Do not give demeclocycline to a child younger than 8 years old. Demeclocycline can affect a child's growth or cause permanent yellowing or graying of the teeth.

Avoid exposure to sunlight or tanning beds. Demeclocycline can make you sunburn more easily. Wear protective clothing and use sunscreen (SPF 30 or higher) when you are outdoors.

Do not take iron supplements, multivitamins, calcium supplements, antacids, or laxatives within 2 hours before or after taking demeclocycline. Also avoid a product that contains bismuth subsalicylate (such as Pepto-Bismol) within 2 hours before or after taking demeclocycline. These medications can make it harder for your body to absorb demeclocycline.

Throw away any unused demeclocycline after the expiration date on the label has passed.

What should I discuss with my healthcare provider before taking Declomycin (demeclocycline)?

You should not take this medication if you are allergic to demeclocycline or to similar antibiotics such as doxycycline (Adoxa, Alodox, Avidoxy, Oraxyl, Doryx, Oracea, Vibramycin), minocycline (Dynacin, Minocin, Solodyn), or tetracycline (Ala-Tet, Brodspec, Panmycin, Sumycin, Tetracap).

To make sure you can safely take demeclocycline, tell your doctor if you have any of these other conditions:

  • kidney disease;

  • liver disease; or

  • diabetes.

If you are being treated for gonorrhea, your doctor may test you to make sure you do not also have syphilis, another sexually transmitted disease.

FDA pregnancy category D. Do not use demeclocycline if you are pregnant. It could harm the unborn baby or cause permanent tooth discoloration later in life. Use effective birth control, and tell your doctor if you become pregnant during treatment.

Demeclocycline can make birth control pills less effective. Ask your doctor about using a non-hormone method of birth control (such as a condom, diaphragm, spermicide) to prevent pregnancy while taking demeclocycline.

Demeclocycline passes into breast milk and may affect bone and tooth development in a nursing baby. You should not breast-feed while you are taking demeclocycline.

Cautions for Declomycin

Contraindications

  • Known hypersensitivity to demeclocycline, other tetracyclines, or any ingredient in the formulation.100

Warnings/Precautions

Warnings

Adverse Dental and Bone Effects

Use during tooth development (e.g., pregnancy, children <8 years of age) may cause permanent yellow-gray to brown discoloration of teeth and enamel hypoplasia100 Effects are most common following long-term use, but may occur following repeated short-term use.100

Tetracyclines form a stable calcium complex in any bone-forming tissue.100 Reversible decrease in fibula growth rate has occurred in prematures receiving tetracycline.100

Use not recommended in children <8 years of age unless other appropriate drugs are ineffective or are contraindicated or unless the benefits in certain indications (e.g., anthrax) outweigh the risks.100 (See Pediatric Use under Cautions.)

Fetal/Neonatal Morbidity

Animal studies indicate possible fetal toxicity (e.g., retardation of skeletal development) and embryotoxicity.100 If used during pregnancy or if patient becomes pregnant while receiving demeclocycline, patient should be apprised of the potential hazard to the fetus.100 (See Pregnancy under Cautions.)

Nervous System Effects

Possibility of adverse CNS effects (light-headedness, dizziness, vertigo) that may impair ability to drive vehicles or operate hazardous machinery.100

Benign intracranial hypertension (pseudotumor cerebri) in adults reported with tetracyclines; usually manifested as headache and blurred vision.100 Bulging fontanels reported in infants.100 Effects usually resolve when drug discontinued, but possibility for permanent sequelae exists.100

Renal Effects

Tetracyclines have antianabolic effects and may increase BUN.100

In patients with impaired renal function, high serum demeclocycline concentrations may result in azotemia, hyperphosphatemia, and acidosis.100 Excessive drug accumulation and possible liver toxicity may occur if usual dosage is used patients with renal impairment.100 (See Renal Impairment under Dosage and Administration.)

Diabetes Insipidus Syndrome

Diabetes insipidus syndrome (polyuria, polydipsia and weakness) reported with long-term demeclocycline therapy.100 Syndrome is nephrogenic, dose-dependent, and reversible when drug discontinued.100

Laboratory Monitoring

Periodically assess organ system function, including renal, hepatic and hematopoietic, during long-term therapy.100

Sensitivity Reactions

Photosensitivity Reactions

Photosensitivity, manifested by an exaggerated sunburn reaction, reported with tetracyclines.100

Photosensitivity reactions may develop within a few minutes to several hours after sun exposure and usually persist 1–2 days after discontinuance of the drug.a Most reactions result from accumulation of tetracyclines in skin and are phototoxic in nature; photoallergic reactions may also occur.a

Discontinue drug at first evidence of skin erythema.100

General Precautions

Superinfection

Possible emergence and overgrowth of nonsusceptible bacteria or fungi.100 Discontinue drug and institute appropriate therapy if superinfection occurs.100

Selection and Use of Anti-infectives

Because many strains of Acinetobacter, Bacteroides, Enterobacter, E. coli, Klebsiella, Shigella, S. pyogenes (group A β-hemolytic streptococci), S. pneumoniae, enterococci, and α-hemolytic streptococci are resistant to tetracyclines (including demeclocycline), in vitro susceptibility tests should be performed if the drug is used for treatment of infections caused by these bacteria.100

Incision and drainage or other surgical procedures should be performed in conjunction with demeclocycline therapy when indicated.100

Specific Populations

Pregnancy

Category D.100 (See Fetal/Neonatal Morbidity under Cautions.)

Lactation

Distributed into milk;100 discontinue nursing or the drug.100

AAP states maternal use of tetracyclines usually is compatible with breast-feeding since absorption of the drugs by nursing infants is negligible.d

Pediatric Use

Should not be used in children <8 years of age unless benefits outweigh the risks.100 (See Adverse Dental and Bone Effects under Cautions.)

Hepatic Impairment

Use with caution.100 Reduce dosage.100

Renal Impairment

Use with caution.100 Reduce dosage.100

Because usual dosage of doxycycline can be used in patients with impaired renal function, it may preferred when a tetracycline is indicated in a patient with impaired renal function.b

Common Adverse Effects

GI effects (anorexia, nausea, vomiting, diarrhea); maculopapular and erythematous rash; dose-related BUN increase; hypersensitivity reactions.100

Interactions for Declomycin

Specific Drugs

Drug

Interaction

Comments

Antacids (aluminum-, calcium-, or magnesium-containing)

Decreased demeclocycline absorption100

Administer antacids containing aluminum, calcium, or magnesium 1–2 hours before or after demeclocyclinea

Anticoagulants, oral

Possible increased anticoagulant effect;100 tetracyclines may impair utilization of prothrombin or decrease vitamin K production by intestinal bacteriaa

Monitor PT carefully; adjust anticoagulant dosage as neededa 100

Hormonal contraceptives

Possible decreased effectiveness of oral contraceptives100

Use alternative nonhormonal contraceptivesa

Iron-containing preparations

Possible decreased absorption of demeclocycline100

Administer demeclocycline 2 hours before or 3 hours after an oral iron preparationa

Methoxyflurane

Possible fatal nephrotoxicity100

Concomitant use not recommendeda

Penicillins

Possible antagonism100

Concomitant use not recommendeda

Usual Adult Dose for SIADH

(Not approved by FDA)

Initial dose: 600 to 1200 mg/day orally in 3 or 4 divided doses
Maintenance dose: 600 to 900 mg/day orally or the lowest effective dosage to prevent hyponatremia

Dialysis

Demeclocycline is not significantly removed by hemodialysis or peritoneal dialysis. Caution and dose reduction or interval prolongation should be considered in patients with renal impairment.

Demeclocycline Breastfeeding Warnings

There are no data on the excretion of demeclocycline into human milk; however, tetracyclines are excreted into human milk in small amounts. Concentrations of tetracycline in milk have averaged 0.6 mcg/mL when the blood level was approximately 1.2 mcg/mL. The theoretical risks of dental staining and inhibition of bone growth exist, although they are unlikely. In one study, tetracycline levels were undetectable in nursing infants. Tetracycline, a related drug, is considered compatible with breast-feeding by the American Academy of Pediatrics. The manufacturer recommends that due to the potential for serious adverse reactions in nursing infants, a decision should be made to discontinue nursing or discontinue the drug, taking into account the importance of the drug to the mother.
