Caution in significant renal impairment (may lead to azotemia, hyperphosphatemia, and acidosis; monitor BUN)
Adjust dose if renal impairment occurs
Anaphylaxis reported; discontinue use and institute supportive therapy
Prolonged use may result in fungal or bacterial superinfection
Lupus, hepatitis, and vasculitis autoimmune syndromes reported with use; discontinue if lupus symptoms occur and assess liver function tests; ANA and CBC
Discontinue therapy if pseudomembranous colitis occurs
Risk of vestibular reactions
Caution in hepatic impairment; discontinue if liver injury occurs
Photosensitivity may occur with prolonged exposure to sunlight or tanning equipment; use skin protection and avoid prolonged exposure to sunlight
Reduce dose in renal impairment; consider drug serum level determinations in prolonged therapy
Tetracycline use during tooth development (last half of pregnancy through age 8 years) can cause tooth enamel hypoplasia or permanent teeth discoloration; more common with long-term use and with repeated, short courses; during pregnancy, may retard skeletal development and reduce bone growth
Fanconi-like syndrome may occur with outdated tetracyclines
Lightheadedness and vertigo may occur; use caution when performing tasks that require mental alertness or operating heavy machinery
May increase BUN secondary to antianabolic effects
Cases of drug rash with eosinophilia and systemic symptoms (DRESS) reported, some fatal; discontinue immediately

Pregnancy Category
Name :
D
Description
There is positive evidence of human fetal risk based on adverse reaction data from investigational or marketing experience or studies in humans, but potential benefits may warrant use of the drug in pregnant women despite potential risks.
Mode of Action
Minocycline inhibits protein synthesis by binding to 30S and possibly 50S ribosomal subunits of susceptible bacteria. It is active against Streptococcus aureus, Neisseria meningitidis, various enterobacteria, Acinetobacter, Bacteroides, Haemophilus and Nocardia spp., and some mycobacteria.
Interaction
Impaired absorption by concomitant admin w/ Ca-containing antacids and other divalent or trivalent cations (e.g. Al, bismuth, Fe, Mg, Zn). May decrease effectiveness of oral contraceptives. May interfere w/ the bactericidal action of penicillins. May potentiate the effect of anticoagulants. Increased risk of nephrotoxicity w/ diuretics. Increased risk of pseudotumour cerebri w/ retinoids (e.g. isotretinoin). Increased risk of ergotism w/ ergot alkaloids.
Potentially Fatal: Concurrent use w/ methoxyflurane may result to fatal renal toxicity.
Pregnancy Category Note
Pregnancy category: D
Lactation: Enters breast milk, some manufacturers say do not nurse; however AAP considers nursing compatible due to calcium chelation of drug and prevention of its absorption; long-term safety of prolonged exposure unknown
