Dermcare Malaseb is a medicated shampoo for dogs and cats, registered to treat seborrhoeic dermatitis associated with bacterial and fungal skin infections. It targets Staphylococcus pseudintermedius bacteria and Malassezia yeast on the skin surface, and is also used as an aid in treating ringworm (dermatophytosis). Available in 250ml and 500ml sizes.

The two active ingredients — chlorhexidine gluconate and miconazole nitrate — work together to reduce microbial populations on the skin. Chlorhexidine is an established antibacterial that disrupts bacterial cell membranes, while miconazole targets fungal organisms including Malassezia yeast. Malaseb is applied and left in contact with the skin for a set contact time before rinsing, allowing the actives to work at the site of infection rather than just washing across the surface. Best used under veterinary guidance, particularly for ongoing or recurring conditions.

Malaseb is a prescription-adjacent product — most owners reach for it after a vet has confirmed a bacterial or fungal skin diagnosis. It's also commonly used to manage recurring conditions, where treating at the first sign of a flare tends to prevent more serious outbreaks from developing.
