Acne Treatment Guidelines
Introduction to Acne Treatment
- The American Academy of Dermatology recommends starting with adapalene 0.1-0.3% gel or tretinoin 0.025-0.1% cream/gel once nightly plus benzoyl peroxide 2.5-5% once daily for mild acne, and adding doxycycline 100 mg once daily or minocycline 100 mg once daily for moderate-to-severe inflammatory acne 1, 2
Topical Retinoid Dosing
- The American Academy of Dermatology recommends applying tretinoin 0.025%, 0.05%, or 0.1% cream or gel once nightly to completely dry skin, starting with lower concentrations in sensitive skin and titrating up as tolerated 1
- Adapalene 0.1% or 0.3% gel can be applied once nightly, and is more photostable than tretinoin and can be used with benzoyl peroxide 1, 3
Benzoyl Peroxide Dosing
- The American Academy of Dermatology recommends applying 2.5-5% gel, cream, or wash once or twice daily, and always combining with antibiotics to prevent bacterial resistance 1, 3
Topical Antibiotic Dosing
- Clindamycin 1% gel, lotion, or solution can be applied twice daily, always combined with benzoyl peroxide, and fixed-combination products can enhance compliance 1, 3
- Erythromycin 2-3% gel or solution can be applied twice daily, always combined with benzoyl peroxide, and fixed-combination products can be used twice daily 1, 3
Oral Antibiotic Dosing
- Doxycycline 100 mg once or twice daily with food is recommended, with a maximum duration of 3-4 months to minimize resistance development 1, 3
- Minocycline 100 mg once or twice daily is conditionally recommended, with a maximum duration of 3-4 months 1, 2, 3
Oral Isotretinoin Dosing
- For severe acne, the American Academy of Dermatology recommends starting with 0.5 mg/kg/day and increasing to 1.0 mg/kg/day as tolerated, targeting a cumulative dose of 120-150 mg/kg 1, 2
- For moderate treatment-resistant acne, 0.25-0.4 mg/kg/day can be used, with equal efficacy and fewer side effects compared to standard dosing 2
Hormonal Therapy Dosing
- Combined oral contraceptives are conditionally recommended for acne with moderate certainty evidence, and should be used at standard contraceptive dosing per product labeling 1, 3
- Spironolactone 25-200 mg daily can be used, particularly for hormonal acne patterns or antibiotic-intolerant patients, without the need for potassium monitoring in healthy patients 1, 3
Additional Topical Agents
- Azelaic acid 15-20% gel or cream can be applied twice daily, particularly for post-inflammatory hyperpigmentation 1, 3
- Clascoterone 1% cream can be applied twice daily, conditionally recommended due to high cost 1, 3
