Elica Cream (Mometasone) for Ringworm: Why It's Inappropriate

Elica cream (mometasone furoate 0.1%) is a potent topical corticosteroid. It should NOT be used for ringworm (tinea corporis).

Why It's Wrong

• Ringworm is a dermatophyte fungal infection (Trichophyton, Microsporum, Epidermophyton).
• Corticosteroids suppress local immunity → fungus proliferates unchecked → tinea incognito (atypical, extensive, less scaly, more inflammatory).
• Masks diagnosis, delays proper treatment, worsens infection.
• Potent steroids on thin skin (groin, face) → atrophy, striae, telangiectasia, periorificial dermatitis.

Correct Treatment

• Topical antifungals (first-line): Terbinafine 1%, clotrimazole 1%, miconazole 2%, ketoconazole 2%, naftifine 1%, ciclopirox 0.77% — BID × 2–4 weeks (1 week beyond clearance).
• Oral antifungals: Terbinafine 250 mg daily × 2–4 wks, itraconazole, fluconazole — for extensive, hair-bearing, or refractory cases.
• Adjuncts: Antiseptic washes, keep dry, loose clothing, treat contacts/pets.

If Already Used Steroid

• Stop steroid immediately.
• Expect transient flare (rebound).
• Start antifungal; may need oral due to deep follicular involvement.
• Dermatology referral if widespread, immunosuppressed, or diagnostic uncertainty.

Antifungals cure ringworm; steroids worsen it. Always confirm diagnosis (KOH prep) before treating.
