From the Guidelines
Topical clindamycin should be applied once daily to the skin where acne lesions appear, covering the entire affected area lightly. This recommendation is based on the most recent and highest quality study available, which provides guidelines for the management of acne vulgaris 1. The study suggests that topical antibiotics, including clindamycin, are effective in treating acne, but recommends against monotherapy and instead suggests combining them with other treatments such as benzoyl peroxide.
Some key points to consider when using topical clindamycin include:
- Applying a thin film to the affected area once daily
- Using enough to cover the entire affected area lightly
- Avoiding contact with eyes, mouth, and mucous membranes
- Washing hands before and after application
- Potential side effects include skin dryness, redness, or irritation, which may be mitigated by reducing application frequency to once daily if necessary
It's also important to note that clindamycin has been shown to have neuromuscular blocking properties, which may enhance the action of other neuromuscular blocking agents 1. Additionally, the medication is classified as pregnancy category B, and it is not known whether clindamycin is excreted in human milk 1.
In terms of specific formulations, clindamycin comes in several forms, including gels, lotions, solutions, and foams, usually in a 1% concentration. Combination products, such as clindamycin and benzoyl peroxide, may also be effective in treating inflammatory acne vulgaris 1. However, the most recent and highest quality study available recommends against using topical antibiotic monotherapy and instead suggests combining them with other treatments 1.
From the FDA Drug Label
Apply a thin film of Clindamycin Phosphate Topical Solution, Clindamycin Phosphate Lotion, or Clindamycin Phosphate Gel twice daily to affected area. The typical dosing regimen for topical clindamycin is to apply a thin film of the solution, lotion, or gel twice daily to the affected area 2.
- Key points:
- Apply a thin film
- Use twice daily
- Apply to the affected area Note: For the lotion, it is recommended to shake well immediately before using 2.
From the Research
Typical Dosing Regimen for Topical Clindamycin
The typical dosing regimen for topical clindamycin in the treatment of acne or other skin infections is as follows:
- Clindamycin 1%/benzoyl peroxide 5% gel: applied twice daily, or as directed by a physician 3
- Clindamycin/zinc gel: applied once daily or twice daily 4
- Clindamycin phosphate 1% solution: applied twice daily 5
- Clindamycin phosphate 1·2%-benzoyl peroxide 3·0% fixed-dose combination gel: applied once daily or twice daily 6
Efficacy and Safety
The efficacy and safety of topical clindamycin have been demonstrated in several studies:
- Clindamycin/benzoyl peroxide gel has been shown to be effective in reducing inflammatory and noninflammatory lesions, with a rapid onset of action and a low incidence of adverse events 3, 7
- Clindamycin/zinc gel has been shown to be as effective as clindamycin lotion in reducing lesions, with a similar safety profile 4
- Clindamycin phosphate 1·2%-benzoyl peroxide 3·0% fixed-dose combination gel has been shown to be effective and safe in Japanese patients with acne, with an acceptable safety and tolerability profile 6
Comparison of Different Regimens
Different regimens of topical clindamycin have been compared in several studies:
- Clindamycin/benzoyl peroxide gel has been shown to be more effective than benzoyl peroxide alone, clindamycin alone, or tretinoin plus clindamycin in reducing lesions 3, 7
- Clindamycin/zinc gel has been shown to be as effective as clindamycin lotion in reducing lesions 4
- Clindamycin phosphate 1·2%-benzoyl peroxide 3·0% fixed-dose combination gel has been shown to be more effective than clindamycin alone in reducing lesions, with an acceptable safety and tolerability profile 6
