Desonide is a low-potency synthetic non-fluorinated corticosteroid used topically for its anti-inflammatory, antipruritic, and vasoconstrictive properties. The 0.05% w/w concentration is a common strength for dermatological use.
Adult: Apply a thin film to the affected area 2 to 3 times daily. Therapy should be limited to 2-4 weeks.
Note: Clean and dry the affected area before application. Apply a thin layer and rub gently. Wash hands after application unless hands are the treated area. Do not cover with occlusive dressings unless directed by a physician. Avoid use on large surface areas, under diapers, or on broken skin unless specifically indicated.
Desonide acts by diffusing across cell membranes and binding with high affinity to specific cytoplasmic glucocorticoid receptors. This drug-receptor complex translocates to the cell nucleus, binds to DNA, and modifies gene transcription. This leads to the synthesis of anti-inflammatory proteins (lipocortins) and inhibition of the synthesis of pro-inflammatory mediators such as prostaglandins and leukotrienes by blocking phospholipase A2. It also inhibits the release of histamine from mast cells, reduces capillary permeability and vasodilation, and suppresses migration of polymorphonuclear leukocytes and fibroblasts, resulting in reduced inflammation, pruritus, and epidermal proliferation.
Pregnancy: Category C: Use only if the potential benefit justifies the potential risk to the fetus. Topical corticosteroids can be absorbed in sufficient amounts to produce systemic effects. Should not be used extensively, for large areas, or for prolonged periods.

| Other topical corticosteroids | Increased risk of additive systemic absorption and local adverse effects (atrophy, striae). | Moderate |
| Topical immunosuppressants (e.g., Tacrolimus, Pimecrolimus) | Concomitant use may increase risk of local immunosuppression and infection. Sequential use is common in therapy. | Moderate |
| Occlusive dressings or wraps | Markedly increases percutaneous absorption, raising the risk of systemic corticosteroid effects and local adverse reactions. | High |
