What Is Ketoconazole Foam Used For?

By killing certain types of fungus, ketoconazole foam can help treat a skin condition called seborrhea. This prescription medicine is approved for use in adults and children as young as 12 years old, and should be used by those who have normal immune systems. There may also be times when ketoconazole foam is used for off-label (unapproved) reasons, such as treating other types of fungal infections.

An Overview of Uses for Ketoconazole Foam

Ketoconazole foam (Extina®) is a prescription skin medication approved for the treatment of seborrheic dermatitis, also known as seborrhea, in people age 12 and older with normal immune systems. Unlike many other seborrhea treatments, ketoconazole foam is not a steroid.
 

What Is Seborrhea?

Seborrhea is a common condition of the skin. It mainly affects the scalp, face, and torso. In its mildest form, it shows up as mild dandruff. More severe symptoms include:
 
  • Yellow, oily scales
  • Pimple-like bumps
  • Hair loss
  • Bright-red inflammation.
 
In infants, seborrhea is commonly known as "cradle cap." Seborrhea tends to come and go, in response to weather, stress, and other changes.
 
It is unclear what exactly causes seborrhea, or if there are different causes for different people. One thought is that overgrowth of normal skin fungus could lead to seborrhea, perhaps because of the skin's reaction to the fungus.
 

How Does It Work?

Ketoconazole foam is part of a group of medications known as antifungals. Seborrhea has been linked to certain types of fungus, and ketoconazole foam is thought to work by killing the fungus, although this is not known for sure at this time.
