It is contraindicated to patients with known hypersensitivity to any of the tetracyclines. It is also contraindicated in severe hepatic disorder and patients with systemic lupus erythematosus. Concomitant intake of alkalis, antacids, and iron may interfere with the absorption of Doxycycline. It is advisable to avoid giving doxycycline in conjunction with penicillin. Doxycycline should not be used in pregnant women unless, in the judgment of the physician, it is essential for the welfare of the patient.

Mode of Action

Doxycycline inhibits bacterial protein synthesis by binding to the 30S ribosomal subunit. It has bacteriostatic activity against a broad range of gm+ve and gm-ve bacteria.


The use of drugs of the tetracycline group during tooth development (last half of pregnancy, infancy, and childhood to the age of 12 years) may cause permanent discoloration of the teeth.

Side Effect

Hypotension, pericarditis, angioneurotic oedema, dyspnoea, serum sickness, peripheral oedema, tachycardia, urticaria, hemolytic anemia, thrombocytopenia, neutropenia, porphyria, eosinophilia, brown-black microscopic discoloration of thyroid tissue, headache, bulging fontanelles in infants and benign intracranial HTN in adults, blurring of vision, scotomata, diplopia, tinnitus, abdominal pain, stomatitis, anorexia, nausea, vomiting, diarrhea, dyspepsia, oesophageal ulceration, discoloration of teeth, enamel hypoplasia, transient increases in LFT and BUN, jaundice, pancreatitis, rashes, exfoliative dermatitis, photo-onycholysis, photosensitivity, arthralgia, myalgia, vaginitis. Potentially Fatal: Anaphylactoid reactions, Stevens-Johnson syndrome, toxic epidermal necrolysis, Clostridium difficile-associated disease (CDAD), hepatotoxicity.

Pregnancy Category Note

Pregnancy Not studied in pregnant patients; the vast majority of reported experience with doxycycline during human pregnancy is short-term, first trimester exposure; there are no human data available to assess effects of long-term therapy of doxycycline in pregnant women, such as that proposed for treatment of anthrax exposure; it should not be used in pregnant women unless, in judgment of physician, it is essential for welfare of patient; evidence of embryotoxicity has been noted in animals treated early in pregnancy Lactation Tetracyclines are excreted in human milk; however, extent of absorption of tetracyclines, including doxycycline, by breastfed infant is not known; short-term use by lactating women is not necessarily contraindicated; however, effects of prolonged exposure to doxycycline in breast milk are unknown;11 because of 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 importance of drug to mother

Impaired absorption w/ antacids containing Al, Ca, or Mg, oral Zn, Fe salts, and bismuth preparations. Increased metabolism w/ phenobarbital, carbamazepine, primidone, and phenytoin. Risk of breakthrough bleeding w/ oral contraceptives. Increased plasma concentration of ciclosporin. Decreased half-life w/ hepatic enzyme inducers (e.g. rifampicin).
