A topical dermatological preparation combining a potent corticosteroid (Betamethasone) with an astringent and mild antiseptic (Zinc Sulfate). Betamethasone provides potent anti-inflammatory, anti-pruritic, and vasoconstrictive effects, while Zinc Sulfate aids in wound healing, reduces exudation, and provides a mild drying and protective effect. This combination is particularly effective for inflammatory dermatoses with exudation or mild infection risk.
Adult: Apply a thin film to the affected area 1-2 times daily. Frequency may be reduced to once daily or on alternate days once control is achieved. Total duration should not exceed 4 weeks continuously without medical review.
Note: 1. Wash and dry the affected area gently. 2. Apply a thin layer and rub in lightly until it disappears. 3. Do not cover with occlusive dressings unless specifically directed by a physician. 4. Avoid contact with eyes, mouth, nostrils, and mucous membranes. 5. Wash hands after application unless hands are the treatment area.
Betamethasone binds to cytoplasmic glucocorticoid receptors, forming a complex that translocates to the nucleus. It modulates gene transcription, leading to the synthesis of anti-inflammatory proteins (lipocortin) and inhibition of pro-inflammatory mediators (cytokines, chemokines, adhesion molecules, enzymes like phospholipase A2 and COX-2). This results in potent anti-inflammatory, immunosuppressive, anti-proliferative, and vasoconstrictive effects. Zinc Sulfate provides astringent action by precipitating proteins, which reduces exudation, forms a protective layer, and has mild antiseptic properties. Zinc is also a cofactor for numerous enzymes involved in tissue repair and immune function.
Pregnancy: Category C (US FDA). Topical corticosteroids can be absorbed in small amounts. Use only if clearly needed and potential benefit justifies potential risk to the fetus. Avoid large amounts or long-term use. Do not apply to breasts if nursing.
Driving: No effect on driving ability.
| Other Topical Corticosteroids | Additive risk of local and systemic side effects. | Major |
| Topical Retinoids (Tretinoin, Adapalene) | May increase skin irritation and dryness. | Moderate |
| Topical Antifungals (e.g., Clotrimazole) | No significant interaction; often used together for infected dermatoses. | None |
| Oral Corticosteroids (e.g., Prednisolone) | Increased risk of systemic corticosteroid effects and HPA axis suppression. | Major |
| Live Vaccines | Systemic immunosuppression may impair vaccine efficacy and increase risk of infection. | Major |
