- Erythromycin gel can be applied once or twice daily depending on formulation 1
- Azelaic acid 20% cream requires twice-daily application (morning and evening) 3

Duration of Treatment
Acne Management
- Continue indefinitely for maintenance after initial 8-12 week treatment phase to prevent recurrence 2
- Maximum lesion reduction typically occurs after 8-12 weeks of continuous use 2
- Discontinuation often leads to acne recurrence, particularly with antibiotic-containing products 1, 2
Psoriasis Treatment
- Short-term trials typically last 4 weeks, with long-term studies extending to 52 weeks 1
- Maintenance therapy duration depends on clinical response and tolerability 1
Application Technique
General Principles
- Apply a thin film to the entire affected area 1, 3
- Wash and dry skin gently before application 1
- Avoid eyes, mouth, nasal creases, and mucous membranes 3
- Allow adequate drying time before applying other products 2
Special Considerations
- Start with once-daily application and monitor for irritation before increasing frequency 3
- If excessive dryness occurs with multiple topical medications, reduce to one product unless directed by a clinician 1
- Minimize sun exposure and use SPF 15 or higher sunscreen with photosensitizing agents 3
Common Pitfalls to Avoid
- Over-application does not improve efficacy and increases irritation risk 1
- Premature discontinuation after initial improvement leads to recurrence, particularly with acne 2
- Combining multiple potentially irritating topicals without medical guidance increases cumulative irritant effects 1, 3
- Applying to wet skin can increase penetration and irritation with certain formulations 1
