How to Apply Clindamycin 20mg/mL (2%) Topical Solution

Application Instructions

Apply a thin film of clindamycin 20mg/mL topical solution twice daily to the affected areas after cleansing and drying the skin. 1

Step-by-Step Application Protocol

• Frequency: Apply twice daily (morning and evening) to areas where acne lesions appear 1
• Amount: Use enough solution to cover the entire affected area lightly with a thin film 2
• Preparation: Shake the solution well immediately before each use 1
• Coverage: Apply to the entire acne-prone area, not just individual lesions 2
• Storage: Keep the container tightly closed when not in use 1

Skin Preparation Before Application

• Wash the affected area with a mild cleanser and pat dry completely before applying the solution 3
• Avoid applying to wet skin, as this can increase irritation 2

Critical Safety Considerations

Absolute Contraindications (Do Not Use If):

• History of hypersensitivity to clindamycin or lincomycin 2, 4
• History of regional enteritis or ulcerative colitis 2
• History of antibiotic-associated colitis or pseudomembranous colitis 2

Important Warnings

• Severe colitis risk: Although rare with topical use, pseudomembranous colitis can occur and may be fatal 2
• Drug interactions: Clindamycin has neuromuscular blocking properties that may enhance other neuromuscular blocking agents 2
• Avoid combination: Do not use with erythromycin-containing products due to antagonistic interaction 4, 3

Optimizing Treatment Efficacy

Combination Therapy Strongly Preferred

Monotherapy with clindamycin alone should be avoided for extended periods due to antibiotic resistance concerns; combination with benzoyl peroxide is strongly preferred. 4

• Fixed-combination products of clindamycin 1%/benzoyl peroxide 5% or 3.75% enhance compliance and reduce resistance risk 4
• The combination is significantly more effective than either agent alone for inflammatory acne 3
• Combination therapy addresses both bacterial suppression and resistance prevention 5, 6

Common Pitfalls to Avoid

• Do not use as monotherapy long-term: This promotes antibiotic resistance 4
• Avoid excessive application: More product does not improve efficacy and increases irritation risk 2
• Do not apply to mucous membranes: Keep away from eyes, mouth, and nasal passages 2
• Avoid hot showers and excessive soap use: These can worsen dryness and irritation 2

Expected Adverse Effects

• Common side effects include dryness, peeling, erythema, pruritus, and burning sensation 2
• These effects are typically mild and can be managed with appropriate moisturizers 2
• If severe irritation develops, reduce application frequency or discontinue use 2

Special Populations

• Pregnancy: Category B—can be used safely in pregnant patients 2, 4
• Pediatric use: Safety and effectiveness not established in children under 12 years of age 2, 4
• Nursing mothers: Unknown if excreted in breast milk; use with caution 2
