Recommended Cream for Psoriasis
For mild to moderate plaque psoriasis, use a combination product containing calcipotriene (vitamin D analog) plus betamethasone dipropionate (potent corticosteroid) applied once daily for 4 weeks, which provides superior efficacy compared to either agent alone. 1
First-Line Treatment Algorithm
For Body/Limb Psoriasis (Non-Facial, Non-Intertriginous)
Start with combination therapy:
- Calcipotriene/betamethasone dipropionate combination product (fixed combination) once daily for 4 weeks is the most effective topical option 1, 2
- This combination achieves maximal improvement within 2-4 weeks in the majority of patients 3
- The fixed combination product is more convenient than separate applications and reduces the risk of inactivation 1, 3
Alternative initial regimens if combination product unavailable:
- Apply high-potency topical corticosteroid (Class II-III) in the morning AND vitamin D analog (calcipotriene) in the evening 1
- Use medium to high-potency corticosteroids (Class II-V) twice daily for 2-4 weeks maximum 2, 4
After initial 4-week treatment period, transition to maintenance:
- Apply high-potency corticosteroid twice daily on weekends only 1
- Apply vitamin D analog (calcipotriene) twice daily on weekdays 1, 4
- This weekend-only corticosteroid regimen reduces adverse effects while maintaining efficacy 1
For Facial and Intertriginous Psoriasis
Use low-potency agents to avoid skin atrophy:
- First-line: Tacrolimus 0.1% ointment twice daily for 8 weeks (65% achieve clear/almost clear skin) 2
- Alternative: Pimecrolimus 0.1% cream twice daily for 8 weeks (71% efficacy) 2
- Alternative: Calcipotriene combined with hydrocortisone for 8 weeks 1
- Calcineurin inhibitors (tacrolimus, pimecrolimus) are preferred because they do not cause skin atrophy, unlike corticosteroids 2, 4
For Scalp Psoriasis
Recommended formulations:
- Calcipotriene foam plus betamethasone dipropionate gel for 4-12 weeks 1
- Superpotent corticosteroids (Class I) like clobetasol propionate 0.05% for up to 4 weeks 2, 4
- Use foam or solution formulations for easier application and better penetration 1
For Palmoplantar Psoriasis
- High-potency corticosteroids (Class I-II) are needed due to thick skin 5
- Vitamin D analogs can be added for combination therapy 1, 5
Corticosteroid Potency Selection by Location
Match potency to body site and disease severity:
- Superpotent (Class I): Thick plaques on body/limbs, palms/soles - maximum 2-4 weeks continuous use 1, 2
- Potent (Class II-III): Body/limb psoriasis - 68-72% efficacy rates 1, 2
- Mid-strength (Class IV-V): Less severe body psoriasis 1
- Low-potency (Class VI-VII): Face, intertriginous areas, children - to prevent skin atrophy 2, 4
Critical Combination Therapy Considerations
Synergistic combinations that enhance efficacy:
- Vitamin D analogs combined with corticosteroids provide synergistic effects superior to monotherapy 1, 6, 3
- Tazarotene 0.1% combined with medium/high-potency corticosteroids for 8-16 weeks reduces irritation while improving efficacy 1
Important compatibility issues to avoid:
- Never apply salicylic acid simultaneously with calcipotriene - the acidic pH inactivates calcipotriene and eliminates its effectiveness 1, 4
- Apply different topical agents at separate times throughout the day to prevent inactivation 2
Common Pitfalls and How to Avoid Them
Duration limits for corticosteroids:
- Class I (superpotent) corticosteroids: maximum 2-4 weeks continuous use to prevent skin atrophy, striae, and systemic absorption 1, 2
- Gradual tapering after clinical response is recommended, though exact protocols vary 1
- Weekend-only application after initial treatment maintains efficacy while reducing adverse effects 1
Local adverse effects of corticosteroids:
- Skin atrophy, striae, folliculitis, telangiectasia, and purpura occur with prolonged use 2
- Use lower potency agents on face, intertriginous areas, and in children 2, 4
Calcineurin inhibitor considerations:
- Burning and itching are common initially but typically improve with continued use 2
- Preferred for facial/intertriginous areas due to lack of atrophy risk 2, 4
Tazarotene precautions:
- Contraindicated in pregnancy (Category X) - must discontinue if pregnancy recognized 1, 2
- Causes significant irritation when used alone; always combine with corticosteroids to reduce this effect 1
Additional Topical Options
For refractory or specific cases:
- Tazarotene 0.1% cream/gel for 8-12 weeks shows comparable efficacy to fluocinonide cream 1
- Coal tar preparations (0.5-10%) can be used as alternative therapy 4
- Anthralin for difficult cases refractory to conventional treatment 5, 7
