Daivobet Ointment is a combination medication containing calcipotriol, a synthetic form of vitamin D, and betamethasone, a corticosteroid. Calcipotriol works by regulating skin cell production and reducing inflammation, while betamethasone helps to further decrease swelling, itching, and redness. This ointment is commonly used to treat psoriasis vulgaris on the body and scalp in adults. It is applied topically to affected areas, helping to improve skin appearance and reduce symptoms associated with psoriasis.
