Off Label Uses
Cellulitis (purulent) due to community-acquired MRSA
Based on the Infectious Diseases Society of America (IDSA) Clinical Practice Guidelines for the Treatment of Methicillin-Resistant Staphylococcus Aureus Infections in Adults and Children, minocycline is effective and recommended in the outpatient management of purulent cellulitis due to community-acquired methicillin-resistant S. aureus (MRSA).
Based on the National Hansen's Disease Program (NHDP) treatment recommendations, minocycline, in combination with other agents, is an effective and recommended alternative agent for treatment of lepromatous (multibacillary) and tuberculoid (paucibacillary) leprosy.
Data from a limited number of patients studied suggest that minocycline, with or without other concomitant antimicrobials, may be beneficial for the treatment of nocardiosis [Anderson 2012], [Dodiuk-Gad 2010], [Petersen 1983]. Additional data may be necessary to further define the role of minocycline in this condition.
Clinical experience also suggests the utility of minocycline in the treatment of nocardiosis, particularly pulmonary [Lerner 1996], [Threlkeld 1997]
Prosthetic Joint Infection
Based on the Infectious Diseases Society of America (IDSA) Diagnosis and Management of Prosthetic Joint Infection: Clinical Practice Guideline, minocycline (based on in vitro susceptibility) given for indefinite chronic oral antimicrobial suppression of prosthetic joint infections is an effective and recommended treatment option. Minocycline is one of the preferred agents for Staphylococci (oxacillin-resistant) infections and is an alternative treatment for infections caused by Cutibacterium spp.
Data from older controlled studies and a meta-analysis have demonstrated a beneficial effect on laboratory parameters and modest clinical benefit in patients with rheumatoid arthritis (RA). Some data suggest that minocycline may be effective in patients with recent-onset disease to reduce the total steroid dose needed.
The American College of Rheumatology (ACR) updated guideline for the treatment of RA did not include minocycline due to its infrequent use in RA and lack of new data since prior publication.

<1%, postmarketing, and/or case reports: Acute renal failure (reversible), anaphylaxis, angioedema, autoimmune hepatitis, balanitis, bulging fontanel, Clostridioides (formerly Clostridium) difficile-associated diarrhea, DRESS syndrome, dysphagia, enterocolitis, eosinophilia, erythema multiforme, exacerbation of systemic lupus erythematosus, exfoliative dermatitis, fixed drug eruption, glossitis, hearing loss, hemolytic anemia, hepatic failure, hepatitis, hepatotoxicity (idiosyncratic) (Chalasani 2014), hypersensitivity reaction, IgA vasculitis, lupus-like syndrome, malignant neoplasm of thyroid, microscopic thyroid discoloration (brown-black), mucous membrane pigmentation, myocarditis, pancreatitis, pericarditis, pneumonitis, polyarthralgia, pseudomembranous colitis, pseudotumor cerebri, pulmonary infiltrates (with eosinophilia), serum sickness, skin photosensitivity, skin pigmentation, Stevens-Johnson syndrome, thrombocytopenia, thyroid dysfunction, tooth discoloration, vasculitis
Concerns related to adverse effects:
• Autoimmune syndromes: Lupus-like, hepatitis, and vasculitis autoimmune syndromes (including serum sickness [eg fever, arthralgia, and malaise]) have been reported; discontinue if symptoms occur and assess liver function tests, ANA, and CBC.
• Benign intracranial hypertension (eg, pseudotumor cerebri [PTC]): Benign intracranial hypertension (headache, blurred vision, diplopia, vision loss, and/or papilledema) has been associated with use. Women of childbearing age who are overweight or have a history of intracranial hypertension are at greater risk. Concomitant use of isotretinoin (known to cause PTC) and minocycline should be avoided. Intracranial hypertension typically resolves after discontinuation of treatment; however, permanent visual loss is possible. If visual symptoms develop during treatment, prompt ophthalmologic evaluation is warranted. Intracranial pressure can remain elevated for weeks after drug discontinuation; monitor patients until they stabilize.
• CNS effects: Lightheadedness, dizziness, and vertigo may occur; patients must be cautioned about performing tasks which require mental alertness (eg, operating machinery or driving). Symptoms usually disappear with continued therapy and when the drug is discontinued.
• Hepatotoxicity: Serious liver injury, including irreversible drug induced hepatitis and fulminant hepatic failure (sometimes fatal) have been reported with use for acne treatment.
• Hyperpigmentation: Hyperpigmentation may occur in nails, bone, skin (including scar and injury sites), eyes, sclerae, thyroid, oral cavity, visceral tissue, and heart valves; skin and oral hyperpigmentation are independent of dose or administration duration.
• Hypersensitivity: Anaphylaxis has been reported; discontinue drug immediately and institute supportive measures.
• Increased BUN: May be associated with increases in BUN secondary to antianabolic effects; use caution in patients with renal impairment as this may lead to azotemia, hyperphosphatemia, acidosis, and possibly to drug accumulation and potential hepatotoxicity.
• Photosensitivity: May cause photosensitivity; discontinue if skin erythema occurs. Use skin protection and avoid prolonged exposure to sunlight; avoid use of use tanning equipment or UVA/B treatment.
• Skin rash: Rash, erythema multiforme, Stevens Johnson syndrome or eosinophilia, fever, and organ failure (Drug Rash with Eosinophilia and Systemic Symptoms [DRESS] syndrome), may occur; onset of symptoms may be delayed up to several weeks; fatal in up to 10% of cases; discontinue treatment immediately if DRESS syndrome is suspected.
• Superinfection: Prolonged use may result in fungal or bacterial superinfection, including C. difficile-associated diarrhea (CDAD) and pseudomembranous colitis; CDAD has been observed >2 months postantibiotic treatment.
• Hepatic impairment: Hepatotoxicity has been reported; use with caution in patients with hepatic impairment or in conjunction with other hepatotoxic drugs.
• Renal impairment: Use with caution in patients with renal impairment (CrCl <80 mL/minute); dosage adjustment recommended.
Concurrent drug therapy issues:
• Drug-drug interactions: Potentially significant interactions may exist, requiring dose or frequency adjustment, additional monitoring, and/or selection of alternative therapy. Consult drug interactions database for more detailed information.
• Pediatric: May cause tissue hyperpigmentation, tooth enamel hypoplasia, or permanent tooth discoloration; more common with long-term use, but observed with repeated, short courses; use of tetracyclines should be avoided during tooth development (infancy and children ≤8 years of age) unless other drugs are not likely to be effective or are contraindicated.
• Pregnancy: Do not use during pregnancy. In addition to affecting tooth development, tetracycline use has been associated with retardation of skeletal development and reduced bone growth.
Dosage form specific issues:
• Magnesium content: Parenteral (IV) formulation contains magnesium; monitor serum magnesium in patients with renal impairment and signs of magnesium intoxication (eg, flushing, sweating, hypotension, depressed reflexes, flaccid paralysis, hypothermia, circulatory collapse, cardiac and CNS depression leading to respiratory paralysis). Also use with caution and closely monitor patients with heart block or myocardial damage.
• Appropriate use: Acne: The American Academy of Dermatology acne guidelines recommends minocycline be used as adjunctive treatment for moderate and severe acne and forms of inflammatory acne that are resistant to topical treatments. Concomitant topical therapy with benzoyl peroxide or a retinoid is recommended should be administered with systemic antibiotic therapy (eg, minocycline) and continued for maintenance after the antibiotic course is completed (AAD [Zaenglein 2016]).
LFTs, BUN, renal function with long-term treatment, serum magnesium in patients with renal impairment; if symptomatic for autoimmune disorder, include ANA, CBC; ophthalmologic evaluation if visual disturbances occur. If used for syphilis, obtain follow up serologic tests 3 months after treatment.
Minocycline crosses the placenta. Tetracycline-class antibiotics may cause fetal harm following maternal use in pregnancy. Rare spontaneous reports of congenital anomalies, including limb reduction, have been reported following maternal minocycline use. Due to limited information, a causal association cannot be established. Tetracyclines accumulate in developing teeth and long tubular bones (Mylonas 2011). Permanent discoloration of teeth (yellow, gray, brown) can occur following in utero exposure and is more likely to occur following long-term or repeated exposure.
As a class, tetracyclines are generally considered second-line antibiotics in pregnant women and their use should be avoided (Mylonas 2011). Minocycline is not recommended for the treatment of Rocky Mountain Spotted Fever (Biggs 2016), Q fever (Anderson 2013), or anthrax infection (Meaney-Delman 2014) in pregnant women. When systemic antibiotics are needed for dermatologic conditions in pregnant women, other agents are preferred (Kong 2013; Murase 2014).
• Discuss specific use of drug and side effects with patient as it relates to treatment. (HCAHPS: During this hospital stay, were you given any medicine that you had not taken before? Before giving you any new medicine, how often did hospital staff tell you what the medicine was for? How often did hospital staff describe possible side effects in a way you could understand?)
• Patient may experience diarrhea, dizziness, fatigue, nausea, vomiting, lack of appetite, or injection site irritation. Have patient report immediately to prescriber signs of liver problems (dark urine, feeling tired, lack of appetite, nausea, abdominal pain, light-colored stools, vomiting, or yellow skin or eyes), signs of pancreatitis (severe abdominal pain, severe back pain, severe nausea, or vomiting), vision changes, blurred vision, urinary retention, change in amount of urine passed, chills, pharyngitis, hearing impairment, joint pain, joint edema, muscle pain, muscle weakness, tinnitus, seizures, shortness of breath, dysphagia, hematuria, angina, arrhythmia, edema, skin discoloration, eye discoloration, nail discoloration, tooth discoloration, gingival changes, bruising, bleeding, severe loss of strength and energy, stomatitis, redness or white patches in mouth or throat, rectal irritation, genital irritation, vaginitis, headache, diplopia, blindness, enlarged lymph nodes, signs of Stevens-Johnson syndrome/toxic epidermal necrolysis (red, swollen, blistered, or peeling skin [with or without fever]; red or irritated eyes; or sores in mouth, throat, nose, or eyes), or signs of Clostridium difficile (C. diff)-associated diarrhea (stomach pain or cramps, very loose or watery stools, or bloody stools) (HCAHPS).
• Educate patient about signs of a significant reaction (eg, wheezing; chest tightness; fever; itching; bad cough; blue skin color; seizures; or swelling of face, lips, tongue, or throat). Note: This is not a comprehensive list of all side effects. Patient should consult prescriber for additional questions.
