- Ointment (0.05%)
- Cream (0.05%)
- Solution (0.05%)
- Foam (0.05%)
- Lotion (0.05%)
Mechanism of Action
Clobetasol exerts:
- Anti-inflammatory effects
- Immunosuppressive effects
- Antiproliferative effects
- Vasoconstrictive properties
Condition-Specific Treatment Protocols
Lichen Sclerosus
Female Patients
- Initial treatment: Apply clobetasol propionate 0.05% ointment once daily for 1 month, then alternate days for 1 month, then twice weekly for 1 month 1
- Maintenance: Use as needed, typically requiring 30-60g annually 1
- Most patients achieve resolution of hyperkeratosis, ecchymoses, and fissuring, though atrophy and color changes may persist
Male Patients
- Initial treatment: Apply clobetasol propionate 0.05% ointment once daily for 1-3 months 1
- For relapse: Consider repeat course for 1-3 months 1
- If phimosis doesn't respond after 1-3 months, refer to urologist for circumcision 1
Psoriasis
Scalp Psoriasis
- Apply twice daily for up to 2 weeks 2
- Do not exceed 50 mL/week 2
- Efficacy rates for class I steroids range from 58-92% 1
Plaque Psoriasis
- Apply to affected areas twice daily for up to 2 weeks
- Consider once-weekly application under hydrocolloid occlusive dressing for resistant cases 3
Bullous Pemphigoid
Localized/Limited Disease
- Apply 10-20g daily to lesional skin only 1
Mild Disease
- Apply 20g daily over entire body except face 1
- Taper after disease control (approximately 15 days)
Extensive Disease
- Apply 30g daily 1
Stevens-Johnson Syndrome/Toxic Epidermal Necrolysis
- For oral mucosa: Mix clobetasol propionate 0.05% with equal amounts of Orabase and apply directly to the sulci, labial or buccal mucosae daily during the acute phase 1
- For urogenital involvement: Consider applying a potent topical corticosteroid ointment once daily to the involved, non-eroded surfaces 1
Application Guidelines
Proper Application Technique
- Apply a thin layer to affected areas only
- Use fingertip unit measurement for appropriate dosing:
- One fingertip unit = approximately 0.5g (enough to cover an area twice the size of an adult hand)
Duration of Treatment
- Short-term use: Treatment beyond 2 consecutive weeks is not recommended for most conditions 2
- Tapering: Gradually reduce frequency of application after clinical response
- Maintenance: For chronic conditions like lichen sclerosus, long-term intermittent use may be necessary 1
Important Cautions and Monitoring
Side Effects to Monitor
- Skin atrophy
- Telangiectasia
- Striae
- Hypothalamic-pituitary-adrenal (HPA) axis suppression
- Tachyphylaxis (decreased effectiveness with continued use)
Risk Minimization
- Avoid application to face, groin, and axillae unless specifically indicated
- Do not use occlusive dressings unless specifically recommended
- Advise patients to wash hands thoroughly after application 1
- Avoid contact with eyes and other sensitive areas
Special Populations
- Pediatric patients: Not recommended for patients under 12 years of age 2
- Pregnant women: Use lowest effective potency and duration
- Elderly: No dosage adjustment necessary, but monitor for increased risk of side effects 2
Efficacy Considerations
- Clobetasol requires at least 2 hours of contact time for optimal effectiveness 4
- Foam formulation may provide greater absorption than solution in certain applications 5
- For resistant lesions, consider intralesional triamcinolone after excluding malignancy 1
Alternative Treatments
Consider alternative treatments when:
- Clobetasol is ineffective after adequate trial
- Side effects are problematic
- Long-term treatment is needed
Options include:
- Lower-potency topical corticosteroids
- Topical calcineurin inhibitors
- Systemic treatments (depending on condition)
Remember that clobetasol propionate is the most potent topical steroid available and should be used judiciously to maximize benefit while minimizing adverse effects.
