What ointment should be used for allergic dermatitis?

Generally, allergic dermatitis is a skin inflammatory condition triggered by exposure to allergens. Common symptoms include pruritus (itching), erythema (redness), and rash. Patients may use topical medications—including calamine lotion, mometasone furoate cream, hydrocortisone butyrate cream, tacrolimus ointment, and cyproheptadine hydrochloride cream—as prescribed by their physician. A detailed analysis follows:

1. Calamine Lotion

Calamine lotion exerts astringent, antipruritic, and protective effects on the skin. It alleviates itching and erythema associated with allergic dermatitis and reduces serous exudation. It is suitable for mild allergic dermatitis, providing symptomatic relief with minimal irritation.

2. Mometasone Furoate Cream

This is a medium-potency corticosteroid that suppresses cutaneous inflammatory responses, thereby reducing erythema, edema, pruritus, and rash. It demonstrates good efficacy against dermatitis induced by various allergens and is indicated for moderate allergic dermatitis.

3. Hydrocortisone Butyrate Cream

A low-potency corticosteroid, hydrocortisone butyrate exhibits mild anti-inflammatory, antiallergic, and antipruritic effects. It effectively relieves skin inflammation and pruritus and is appropriate for mild-to-moderate allergic dermatitis—particularly on delicate or sensitive skin areas.

4. Tacrolimus Ointment

An immunosuppressant, tacrolimus inhibits local cutaneous immune responses, thereby reducing inflammation and pruritus. It is indicated for moderate-to-severe allergic dermatitis, especially in patients who respond inadequately to corticosteroids or in whom corticosteroid use is contraindicated.

5. Cyproheptadine Hydrochloride Cream

This agent possesses antiallergic and antipruritic properties by blocking histamine receptors. It effectively alleviates intense pruritus associated with allergic dermatitis and is suitable for all types of allergic dermatitis, with particularly notable improvement in pruritus symptoms.

In daily life, patients should maintain healthy lifestyle habits: avoid exposure to common allergens such as pollen and house dust mites; refrain from consuming spicy or irritating foods—including Sichuan pepper, chili peppers, and garlic; and keep the skin clean and dry to facilitate recovery.
