🩺 Clinical
Minocycline is used to treat infections caused by bacteria and certain other infections spread by ticks, lice, mites, and infected animals. It is also used to treat acne and rosacea (a skin disease that causes redness, flushing, and pimples on the face). Minocycline is in a class of medications called tetracycline antibiotics. It works to treat infections by preventing the growth and spread of bacteria. It works to treat acne and rosacea by killing the bacteria that infects pores and by lowering the amount of oil on your skin that can cause acne. Antibiotics such as minocycline will not work f...

⚠️ Warnings and Cautions ▾
5 WARNINGS AND PRECAUTIONS Serious Skin/Hypersensitivity Reactions: Minocycline has been associated with anaphylaxis, serious skin reactions, erythema multiforme, and drug rash with eosinophilia and systemic symptoms (DRESS) syndrome. Discontinue immediately if symptoms occur. ( 5.1 ) Tooth Discoloration and Enamel Hypoplasia: Use during the second and third trimesters of pregnancy, infancy, and childhood up to the age of 8years may cause permanent discoloration of the teeth (yellow-gray-brown).
( 5.2 , 8.1 , 8.4 ) Inhibition of Bone Growth: Use during the second and third trimesters of pregnancy, infancy, and childhood up to the age of 8 years may cause reversible inhibition of bone growth. ( 5.3 , 8.1 , 8.4 ) Clostridioides difficile-Associated Diarrhea (Antibiotic-Associated Colitis) : Discontinue if Clostridioides difficile-associated diarrhea (antibiotic-associated colitis) occurs. ( 5.4 ) Hepatotoxicity: Discontinue if liver injury is suspected.
( 5.5 ) Central Nervous System Effects: May cause central nervous system side effects including light-headedness, dizziness, or vertigo. ( 5.6 ) Idiopathic Intracranial Hypertension: May cause idiopathic intracranial hypertension in adults and adolescents. Discontinue if symptoms occur.
( 5.7 ) Autoimmune Syndromes: Minocycline has been associated with autoimmune syndromes; discontinue immediately if symptoms occur. ( 5.8 ) Metabolic Effects: If renal impairment exists, reduce minocycline dosage. ( 5.9 )
5.1Serious Skin/Hypersensitivity Reactions Cases of anaphylaxis, serious skin reactions (e.g., Stevens-Johnson syndrome), erythema multiforme, and drug rash with eosinophilia and systemic symptoms (DRESS) syndrome have been reported postmarketing with minocycline use in patients with acne. DRESS syndrome consists of cutaneous reaction (such as rash or exfoliative dermatitis), eosinophilia, and one or more of the following visceral complications such as: hepatitis, pneumonitis, nephritis, myocarditis, and pericarditis.
Fever and lymphadenopathy may be present. In some cases, death has been reported. If this syndrome is recognized, discontinue minocycline immediately.
5.2Tooth Discoloration and Enamel Hypoplasia The use of tetracycline-class drugs, including minocycline, during tooth development (second and third trimesters of pregnancy, infancy, and childhood up to the age of 8 years) may cause permanent discoloration of the teeth (yellow-gray -brown). Permanent discoloration of the teeth is more common during long-term use of tetracycline-class drugs but has been observed following repeated short-term courses. Enamel hypoplasia has also been reported.
Use of minocycline is not recommended during tooth development. Advise the patient of the potential risk to the fetus if minocycline is used during the second or third trimester of pregnancy [see Use in Specific Populations ( 8.1 , 8.4 )].
5.3Inhibition of Bone Growth The use of tetracycline-class drugs, including minocycline, during the second and third trimesters of pregnancy, infancy, and childhood up to the age of 8 years may cause reversible inhibition of bone growth. All tetracyclines, including minocycline, form a stable calcium complex in any bone-forming tissue. A decrease in fibula growth rate has been observed in premature human infants given oral tetracycline in doses of 25 mg/kg every 6 hours.
This reaction was shown to be reversible when the drug was discontinued. Advise the patient of the potential risk to the fetus if minocycline is used during the second or third trimester of pregnancy [see Use in Specific Populations ( 8.1 , 8.4 )].
5.4Clostridioides difficile -Associated Diarrhea (Antibiotic-Associated Colitis) Clostridioides difficile -associated diarrhea (CDAD) has been reported with nearly all antibacterial agents, including minocycline, and may range in severity from mild diarrhea to fatal colitis. C. difficile produces toxins A and B which contribute to the development of CDAD. Hypertoxin-producing strain…

6.1Clinical Trials Experience Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug, and may not reflect the rates observed in practice. The following table summarizes selected adverse reactions reported in clinical trials at a rate of > 1% for minocycline hydrochloride extended-release tablets and higher than placebo. Adverse Reactions Minocycline Hydrochloride Extended-Release Tablets (1 mg/kg) N = 674 (%) PLACEBO N = 364 (%) At least one treatment-emergent event 379 (56) 197 (54) Fatigue 62 (9) 24 (7) Dizziness 59 (9) 17 (5) Pruritus 31 (5) 16 (4) Malaise 26 (4) 9 (3) Somnolence 13 (2) 3 (1) Urticaria 10 (2) 1 (0) Tinnitus 10 (2) 5 (1) Arthralgia 9 (1) 2 (0) Vertigo 8 (1) 3 (1)
6.2Postmarketing Experience The following adverse reactions have been reported with minocycline hydrochloride use in a variety of indications. Because these reactions are reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency or establish a causal relationship to drug exposure. Skin and hypersensitivity reactions: anaphylaxis, angioedema, DRESS syndrome, erythema multiforme, Stevens-Johnson syndrome, acute febrile neutrophilic dermatosis (Sweet's syndrome), fixed drug eruptions, balanitis, anaphylactoid purpura, photosensitivity, pigmentation of skin and mucous membranes.
Autoimmune conditions: polyarthralgia, pericarditis, exacerbation of systemic lupus, pulmonary infiltrates with eosinophilia, lupus-like syndrome. Central nervous system: idiopathic intracranial hypertension, bulging fontanels in infants, decreased hearing. Endocrine: brown-black microscopic thyroid discoloration, abnormal thyroid function.
Oncology: thyroid cancer. Oral: glossitis, dysphagia, tooth discoloration. Gastrointestinal: enterocolitis, pancreatitis, hepatitis, liver failure.
Renal: acute renal failure. Hematology : hemolytic anemia, thrombocytopenia, eosinophilia.
🔄 Drug Interactions ▾
7 DRUG INTERACTIONS Patients who are on anticoagulant therapy may require downward adjustment of their anticoagulant dosage. ( 7.1 )
7.1Anticoagulants Because tetracyclines have been shown to depress plasma prothrombin activity, patients who are on anticoagulant therapy may require downward adjustment of their anticoagulant dosage.
7.2Penicillin Because bacteriostatic drugs may interfere with the bactericidal action of penicillin, avoid giving minocycline hydrochloride in conjunction with penicillin.
7.3Antacids and Iron Preparations Absorption of tetracyclines is impaired by antacids containing aluminum, calcium, or magnesium and iron-containing preparations.
7.4Drug/Laboratory Test Interactions False elevations of urinary catecholamine levels may occur due to interference with the fluorescence test.
👥 Use in Specific Populations ▾
8 USE IN SPECIFIC POPULATIONS Lactation: Breastfeeding is not recommended. ( 8.2 ).
8.1Pregnancy Risk Summary Tetracycline class drugs, including minocycline may cause permanent discoloration of deciduous teeth and reversible inhibition of bone growth when administered during the second and third trimesters of pregnancy [see Warnings and Precautions ( 5.2 , 5.3 ) and Use in Specific Populations ( 8.4 )]. A few postmarketing cases of limb reductions have been reported over decades of use; however, the association is unclear. The limited data from postmarketing reports are not sufficient to inform a drug-associated risk for birth defects or miscarriage.
In animal reproduction studies conducted in pregnant rats and rabbits, fetuses with bent limb bones were observed following oral administration of minocycline during organogenesis at systemic exposures 3 and 2 times, respectively, the exposure associated with the maximum recommended human dose (MRHD) (see Data) . If a patient becomes pregnant while taking this drug, advise the patient of the risk to the fetus and to discontinue treatment. The background risk of major birth defects and miscarriage for the indicated population is unknown.
All pregnancies have a background risk of birth defect, loss, or other adverse outcomes. In the U.S. general population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2 to 4% and 15 to 20%, respectively. Data Human Data The use of tetracycline class drugs, including minocycline, during tooth development (second and third trimesters of pregnancy, infancy, and childhood up to the age of 8 years) may cause permanent discoloration of deciduous teeth (yellow-gray-brown).
Permanent discoloration of the teeth is more common during long-term use of the drug but has been observed following repeated short-term courses [see Warnings and Precautions ( 5.2 )] . Animal Data Results of animal studies indicate that tetracyclines cross the placenta, are found in fetal tissues, and can cause delayed skeletal development in the developing fetus. Evidence of embryotoxicity has been noted in animals treated early in pregnancy [see Warnings and Precautions ( 5.3 )].
Minocycline induced skeletal malformations (bent limb bones) in fetuses when administered to pregnant rats and rabbits during the period of organogenesis at doses of 30 mg/kg/day and 100 mg/kg/day, respectively (3 times the MRHD and 2 times the MRHD on an AUC comparison basis, respectively). Reduced mean fetal body weight was observed in studies in which minocycline was administered to pregnant rats at an oral dose of 10 mg/kg/day (approximately equal to the MRHD on an AUC comparison basis). Minocycline was assessed for effects on peri- and post-natal development of rats in a study that involved oral administration to pregnant rats during the period of organogenesis through lactation at dosages of 5 mg/kg/day, 10 mg/kg/day, or 50 mg/kg/day.
In this study, body weight gain was significantly reduced in pregnant females that received 50 mg/kg/day (2.5 times the MRHD on an AUC comparison basis). No effects of treatment on the duration of the gestation period or the number of live pups born per litter were observed. Gross external anomalies observed in offspring of animals that received minocycline included reduced body size, improperly rotated forelimbs, and reduced size of extremities.
No effects were observed on the physical development, behavior, learning ability, or reproduction of the offspring of animals that received minocycline.
8.2Lactation Risk Summary Tetracycline-class antibiotics, including minocycline, are present in breast milk following oral administration. There are no data on the effects of minocycline on milk production. Because of the potential for serious adverse reactions, including tooth discoloration and inhibition of bone growth, advise patients that breastfeeding is not recommended during minocycline therapy and for 4 day…

🧒 Pediatric Use ▾
8.4Pediatric Use The safety and effectiveness of minocycline hydrochloride have been established in pediatric patients 12 years of age and older for the treatment of inflammatory lesions of non-nodular moderate to severe acne vulgaris [see Clinical Studies ( 14 )] . Tooth discoloration and inhibition of bone growth have been observed in pediatric patients [see Warnings and Precaution ( 5.2 , 5.3 )] . Use of tetracycline-class antibiotics below the age of 8 is not recommended due to the potential for tooth discoloration [see Warnings and Precautions ( 5.2 )] .
Safety and effectiveness of minocycline have not been established in pediatric patients younger than 12 years of age.
🧓 Geriatric Use ▾
8.5Geriatric Use Clinical studies of minocycline hydrochloride extended-release tablets did not include sufficient numbers of subjects aged 65 and over to determine whether they respond differently from younger subjects. Other reported clinical experience has not identified differences in responses between the elderly and younger patients. In general, dose selection for an elderly patient should be cautious, usually starting at the low end of the dosing range, reflecting the greater frequency of decreased hepatic, renal, or cardiac function, and concomitant disease or other drug therapy.
🆘 Overdosage ▾
10 OVERDOSAGE Minocycline is not removed in significant quantities by hemodialysis or peritoneal dialysis. In case of overdosage, discontinue minocycline, treat symptomatically, and institute supportive measures. Call Poison Control Center at 1-800 222-1222 for the latest recommendations.
🧬 Clinical Pharmacology ▾
12 CLINICAL PHARMACOLOGY
12.1Mechanism of Action The mechanism of action of minocycline hydrochloride extended-release tablets for the treatment of acne is unknown.
12.2Pharmacodynamics The pharmacodynamics of minocycline hydrochloride extended-release tablets for the treatment of acne are unknown.
12.3Pharmacokinetics Minocycline hydrochloride extended-release tablets are not bioequivalent to non-modified release minocycline products. Based on pharmacokinetic studies in healthy adults, minocycline hydrochloride extended-release tablets produce a delayed T max at 3.5 hours to 4 hours as compared to a non-modified release reference minocycline product (T max at 2.25 hours to 3 hours). At steady-state (Day 6), the mean AUC (0 to 24) and C max were 33.32 mcg×hr/mL and 2.63 mcg/mL for minocycline hydrochloride extended-release tablets and 46.35 mcg×hr/mL and 2.92 mcg/mL for minocycline hydrochloride capsules, respectively.
These parameters are based on dose adjusted to 135 mg/day for both products. A single-dose, four-way crossover study demonstrated that minocycline hydrochloride extended-release tablets used in the study (45 mg, 90 mg, 135 mg) exhibited dose-proportional pharmacokinetics. In another single-dose, five-way crossover pharmacokinetic study, minocycline hydrochloride extended-release tablets 55 mg, 80 mg, and 105 mg were shown to be dose-proportional to minocycline hydrochloride extended-release tablets 90 mg and 135 mg.
