Minocycline is a tetracycline-class antibiotic used for acne and resistant infections when first-line options are unsuitable.
Limit duration to reduce hyperpigmentation, autoimmune reactions, and drug-induced lupus.
Monitor for dizziness, vertigo, or tinnitus, especially during the first week—dose at bedtime if tolerated.
Warn about potential skin, teeth, and mucosal hyperpigmentation with long-term use.
Check baseline and periodic liver function tests for chronic therapy.
Consider switching to doxycycline in patients prone to vestibular symptoms or needing long-term therapy.
Minocycline is a lipophilic tetracycline used primarily for inflammatory acne and certain resistant gram-positive infections when other agents are unsuitable.
Reserve minocycline for adolescents requiring systemic acne therapy or culture-proven infections responsive to tetracyclines. Consider antimicrobial stewardship—many infections have safer or narrower alternatives.
| Condition | Age Range | First Line? | Notes |
|---|---|---|---|
| Moderate to severe inflammatory acne | Adolescents | Yes | Use in combination with topical retinoids and benzoyl peroxide; reassess benefit and taper after 3–4 months to limit antimicrobial resistance and pigmentation changes. |
| Skin and soft tissue infections caused by susceptible community-associated MRSA | Children and adolescents | No | Reserve for culture-confirmed susceptible strains when clindamycin or trimethoprim-sulfamethoxazole are contraindicated or ineffective; monitor for vestibular side effects. |
| Meningococcal prophylaxis in severe beta-lactam allergy | Adolescents | No | Consider only when rifampin, ciprofloxacin, and azithromycin are contraindicated; follow public health guidance and ensure adherence to a 2-day regimen. |

Minocycline side effects include dizziness, GI upset, and skin pigmentation changes.
Vestibular effects are dose-related and often improve with continued use or dose reduction.

Administration pearls for minocycline in adolescents.
Administer with a full glass of water. Staying upright for 30 minutes helps prevent esophageal irritation. Avoid taking with calcium, magnesium, or iron supplements.
Minocycline crosses the blood-brain barrier more than doxycycline and can cause dizziness—dose at bedtime if tolerated.
Emergency contact: Seek care for severe dizziness, difficulty breathing, facial swelling, or widespread rash.
Continue topical acne regimen alongside oral therapy and schedule regular dermatology follow-up.

Minocycline is a second-generation tetracycline with high lipid solubility, enabling excellent tissue penetration—including skin, lungs, and CNS. It exerts bacteriostatic activity by inhibiting protein synthesis at the 30S ribosomal subunit.
By reversibly binding the 30S subunit, minocycline blocks attachment of aminoacyl-tRNA to the ribosomal acceptor site, halting elongation of the peptide chain. Its lipophilicity allows passage across the blood–brain barrier, accounting for both therapeutic CNS activity and vestibular adverse effects.

Understanding your child's medication is important. We've created comprehensive guides to help you safely administer Minocycline and monitor your child's response to treatment.
Minocycline can affect the inner ear. Dizziness often improves after a few doses but call if it is severe.
Long-term use can cause blue-gray discoloration of skin, nails, or teeth. Regular monitoring helps detect this early.
For acne, dermatologists typically limit oral antibiotics to 3-4 months while continuing topical treatments.
Probiotics may help GI tolerance and can be taken 2 hours after the antibiotic.
