Application and Withdrawal of Mometasone (Momate) Cream for Plantar Psoriasis/Eczema
For plantar psoriasis or eczema, apply mometasone 0.1% cream once daily to affected areas, combine with an emollient for superior results, and when withdrawing, gradually reduce frequency to 2-3 times weekly rather than stopping abruptly to prevent rebound flares.
Initial Treatment Phase
Application Instructions
- Apply once daily to affected plantar surfaces 12
- Apply a thin layer to the entire affected area
- Always combine with emollients - this combination significantly improves outcomes compared to mometasone alone, reducing desquamation and symptoms while preventing quick relapse 3
- Continue daily application for 4-8 weeks until clinical improvement is achieved 3
Enhanced Efficacy Strategies
For plantar psoriasis specifically:
- Add salicylic acid 5% for the first 7 days if significant hyperkeratosis is present, then continue with mometasone alone - this sequential approach achieves 44% PASI reduction in the first week versus 37% with mometasone alone 4
- The combination of mometasone with salicylic acid is safe and particularly effective for thick plantar lesions 3
Maintenance and Withdrawal Strategy
Gradual Tapering Protocol (Critical to Prevent Rebound)
Once clinical improvement is achieved, do not stop abruptly. The guidelines explicitly warn that abrupt withdrawal can cause rebound flares 3. Instead:
Recommended tapering schedule:
Option A (Preferred): Apply mometasone 3 times weekly (e.g., Sunday, Tuesday, Thursday) for up to 36 weeks 5
- This schedule maintains 83% of patients relapse-free
Option B (Alternative): Apply 2 times weekly (e.g., Saturday, Sunday) for maintenance 5
- This maintains 68% of patients relapse-free
Continue emollients daily throughout the tapering period and indefinitely - this prevents quick relapse when corticosteroids are reduced 3
Evidence for Gradual Reduction
The 2021 AAD-NPF guidelines specifically state: "Gradual reduction in the frequency of use after clinical improvement is recommended" 3. A landmark study of 120 patients with chronic hand eczema (similar thick skin to plantar surfaces) demonstrated that intermittent maintenance therapy with mometasone was highly effective and safe for up to 36 weeks 5.
Key Clinical Considerations
Common Pitfalls to Avoid
- Never stop abruptly - this is the most common error leading to rebound flares 3
- Don't skip emollients - they are not optional; they significantly enhance outcomes and prevent relapse 3
- Avoid salicylic acid after the initial week if using vitamin D analogs concurrently, as the acidic pH inactivates calcipotriene 3
Monitoring for Adverse Effects
While mometasone has low atrophogenic potential compared to other potent steroids 1, 2:
- Monitor for skin atrophy, though risk is lower on thick plantar skin
- Watch for local burning or irritation (usually transient)
- Systemic absorption is minimal due to high lipophilicity and rapid hepatic metabolism 2
When to Adjust Treatment
If relapse occurs during tapering:
- Resume daily application for 3 weeks to regain control 5
- This can be done up to 2 separate times during the maintenance phase
- Then return to the intermittent schedule
Duration of Therapy
Long-term intermittent treatment (up to 36 weeks) with mometasone has been proven both effective and safe 5, making it suitable for chronic plantar conditions that often require extended management.
Practical Implementation
Week 1-8 (Acute Phase):
- Mometasone 0.1% cream once daily
- Consider adding salicylic acid 5% for first 7 days if thick scales present
- Emollient twice daily to all affected areas
Week 9 onwards (Maintenance Phase):
- Mometasone 0.1% cream 2-3 times weekly
- Emollient twice daily continuously
- Resume daily mometasone for 3 weeks if flare occurs, then return to intermittent schedule
This structured approach, based on Level II evidence 3, 5, maximizes disease control while minimizing steroid exposure and preventing the rebound phenomenon that occurs with abrupt cessation.
