Overview
Betamethasone valerate is a potent topical corticosteroid used to treat inflammatory and pruritic skin conditions. It works by reducing inflammation, itching, and redness associated with various dermatoses. Available in multiple formulations, it is applied directly to affected skin areas.
Mechanism of Action
Betamethasone valerate is a synthetic glucocorticoid that binds to intracellular glucocorticoid receptors, inhibiting the production of inflammatory mediators like prostaglandins and leukotrienes. It suppresses inflammatory cell migration, reduces capillary permeability, and stabilizes lysosomal membranes, leading to anti-inflammatory, antipruritic, and vasoconstrictive effects.
Indications
- Inflammatory manifestations of corticosteroid-responsive dermatoses
- Pruritic manifestations of corticosteroid-responsive dermatoses
Common Doses
- 0.1% cream
- 0.1% ointment

Dosage
Apply a thin film of cream or ointment to affected areas 1-3 times daily (often effective with 1-2 times daily). Apply lotion by massaging a few drops into affected area twice daily (morning and night). Increase frequency in stubborn cases, then reduce to once daily after improvement. For economical use, apply nozzle close to skin and squeeze gently.
