What are the recommended topical cream names and doses for treating eczema or dermatitis?

Recommended Topical Creams and Doses for Treating Eczema/Dermatitis

For treating eczema or dermatitis, the recommended first-line topical treatments are moisturizers and emollients for mild cases, with topical corticosteroids of appropriate potency based on severity and location for moderate to severe cases. 1, 2

First-Line Treatments

Emollients and Moisturizers

• Apply at least once daily to the whole body
• Most effective when applied after bathing
• Should be used as soap substitutes for cleansing the skin
• Use oil-in-water creams or ointments rather than alcohol-containing lotions 1

Topical Corticosteroids

Based on severity and location:

1. Mild Eczema/Dermatitis:

   • Low-potency corticosteroids (e.g., hydrocortisone 1% cream/ointment)
   • Apply once or twice daily for affected areas
   • Safe for sensitive areas (face, neck, genitals, body folds) 2

2. Moderate Eczema/Dermatitis:

   • Medium-potency corticosteroids (e.g., clobetasone butyrate 0.05% cream/ointment)
   • Apply once or twice daily for up to 12 weeks
   • First choice for most patients 2, 3

3. Severe Eczema/Dermatitis:

   • Potent corticosteroids for limited periods
   • Apply once daily (equally effective as twice daily) 4
   • Use for up to 12 weeks with periodic breaks 3

Application Guidelines

• Use the fingertip unit method: one fingertip unit (amount from fingertip to first crease) covers approximately 2% body surface area 3
• Apply a thin layer to affected areas only
• For most cases, once-daily application is as effective as twice-daily 4
• Duration:
  • Super-high-potency: up to 3 weeks
  • High/medium-potency: up to 12 weeks
  • Low-potency: no specific time limit 3

Second-Line Treatments

Topical Calcineurin Inhibitors

When topical corticosteroids are ineffective or contraindicated:

1. Pimecrolimus 1% cream:

   • Indicated for mild-to-moderate atopic dermatitis in adults and children ≥2 years
   • Apply thin layer twice daily to affected areas
   • Particularly useful for sensitive areas (face, neck, intertriginous areas) 2, 5
   • Should not be used continuously for long periods 5

2. Tacrolimus ointment:

   • 0.03% or 0.1% for moderate-to-severe atopic dermatitis
   • Apply thin layer twice daily
   • Effective for steroid-resistant cases 2

Special Considerations

For Infected Eczema/Dermatitis

• Take bacterial swabs if infection is suspected
• For Staphylococcus aureus (most common): flucloxacillin
• For penicillin allergy: erythromycin 1
• Consider antiseptic baths (potassium permanganate 1:10,000) 1

For Severe Itching

• Oral antihistamines (sedating types most effective)
• Topical polidocanol-containing creams 1
• Avoid topical antihistamines due to risk of contact dermatitis 2

For Fissures

• Propylene glycol 50% in water for 30 minutes under plastic occlusion nightly
• Follow with hydrocolloid dressing
• Alternative: antiseptic baths or silver nitrate solutions 1

Important Precautions

1. Avoid in children under 2 years: Pimecrolimus should not be used in children under 2 years of age 5

2. Risk of skin thinning: Higher with prolonged use and higher potency corticosteroids. Only 1% of patients develop this complication in clinical trials 4

3. Avoid on infected skin: Resolve bacterial or viral infections before starting treatment 5

4. Monitoring: Reassess after 2 weeks of treatment; if no improvement, consider stepping up potency or alternative treatments 1

5. Tachyphylaxis: The value of antihistamines may be reduced with continued use 1

By following these guidelines and selecting the appropriate topical treatment based on severity, location, and patient factors, most cases of eczema and dermatitis can be effectively managed with minimal adverse effects.
