• Eczema and dermatitis

Combination products (e.g. with neomycin or clioquinol) are used when bacterial or fungal infections are also present[1]. 

How does betamethasone work?

Betamethasone reduces inflammation by acting directly on the skin's immune response[1]:

It is classified as a potent steroid, meaning it is stronger than mild or moderate corticosteroids.
