Pregnancy-Lactation
Pregnancy

Pregnant women with renal disease may be more prone to develop tetracycline-associated liver failure
The effect of tetracyclines on labor and delivery is unknown
Lactation
Short-term use of tetracycline is acceptable in nursing mothers
A number of reviews have stated that tetracycline is contraindicated during breastfeeding because of possible staining of infants' dental enamel or bone deposition of tetracyclines; however, a close examination of available literature indicates that there is not likely to be harm in short-term use of tetracycline during lactation because milk levels are low and absorption by the infant is inhibited by the calcium in breast milk
Tetracycline is excreted into breast milk in low concentrations (milk:plasma ratio ranges between 0.25 and 1.5)
NIH LactMed and the American Academy of Pediatrics classifies tetracycline as compatible with breastfeeding
Interactions
Impaired absorption w/ antacids containing divalent and trivalent cations (e.g. Al, Ca, Mg), Fe, Zn and Na bicarbonate preparations, kaolin-pectin, bismuth subsalicylate, sucralfate, strontium ranelate, colestipol and colestyramine. May interfere w/ the bactericidal action of penicillin. May potentiate the effect of anticoagulants. May decrease efficacy of oral contraceptives. Nephrotoxic effects may be exacerbated by diuretics or other nephrotoxic drugs. May increase the hypoglycaemic effect of insulin and sulfonylureas in patients w/ DM. May increase toxic effects of ergot alkaloids and methotrexate.
Potentially Fatal: Concurrent methoxyflurane may result to fatal renal toxicity. Increased risk of benign intracranial HTN w/ vit A or retinoids (e.g. acitretin,isotretinoin, tretinoin).

Mode of Action
Tetracycline exhibits its bacteriostatic action by reversibly binding to the 30S subunits of the ribosome, thus preventing protein synthesis and arresting cell growth. It has a broad spectrum of antimicrobial activity including Chlamydiaceae, Mycoplasma spp., Rickettsia spp., spirochaetes, many aerobic and anaerobic gm+ve and gm-ve pathogenic bacteria and some protozoa.
