    1. May combine with Benzoyl Peroxide (e.g. Benzaclin)
  5. Consider Adjunctive Acne Vulgaris Management
  1. General
    1. Do not expect an effect for 6 to 8 weeks
    2. Continue Antibiotic for minimum of 6 months
    3. Benzoyl Peroxide should be used with all Antibiotic regimens to prevent Antibiotic Resistance
    4. As with topical Antibiotic Resistance in acne, oral Antibiotic Resistance is also increasing
    5. Stop oral Antibiotics after acne improves (after 3-4 months) and continue topical agents
  2. First Line
    1. Doxycycline
      1. Dose: 50-100 mg once to twice daily
      2. May substitute Tetracycline 250 to 500 mg daily to twice daily
        1. Doxycycline replaces Tetracycline as first-line therapy as of the 2007 AAD guidelines
      3. Pregnancy Category D
    2. Erythromycin
      1. Dose: 1 g/day in 2-4 divided doses
      2. Increasing resistance decreases its efficacy (compared with Tetracyclines)
        1. Avoid in Acne Vulgaris, unless Tetracyclines are contraindicated
      3. Pregnancy Category B
  3. Alternative agents
    1. Indicated if first-line agents not tolerated

      2. Considered first-line therapy by American Academy of Dermatology
      3. Risk of serious adverse effects (e.g. lupus-like reaction, Pseudotumor Cerebri)
      4. Pregnancy Category D
  • Management
  • Step 3 - Maximal medical therapy (cystic or refractory acne)
  1. Isotretinoin (Accutane)
    1. Consider in all patients with resistant or Cystic Acne (scarring)
    2. Dose
      1. Start 0.25 to 0.4 mg/kg/day (or 0.5 mg/kg/day if severe)

      3. Continue for 20 weeks
    3. Only qualified clinicians may prescribe (iPLEDGE)
    4. Adverse effects
      1. Extremely Teratogenic
      2. Monitor Triglycerides and Liver Function Tests and Complete Blood Count
      3. Major Depression and increased Suicidality
  2. Light and laser therapy
    1. Awaiting larger, more definitive studies as to efficacy
