Extina Dosage

Extina comes as a foam that is applied twice daily for four weeks. This is the standard Extina dosage for everyone, regardless of the severity of your skin condition. Because the foam melts with warmth, do not put it in the palm of your hand; rather, dispense your dose into the cap or another cool surface and pick up only small bits of the foam at a time.

An Introduction to Dosing With Extina

There is only one standard dose of Extina® (ketoconazole foam). As is always the case, do not adjust your dosage unless your healthcare provider specifically tells you to do so.

What Is the Recommended Extina Dosage?

For seborrhea treatment, Extina is applied twice a day for four weeks. It is possible that your healthcare provider might recommend repeat treatments, although it is unclear whether repeat treatments are beneficial; the prescribing information for Extina does not mention the possibility of more than one treatment. For many people, seborrhea tends to come and go, and it is possible that repeat treatments might be useful.
Although the fact that Extina comes as a foam makes it ideal for use on the scalp, there is no reason why it cannot be used to treat seborrhea on other parts of the body too.

General Information for Using Extina

Some considerations to keep in mind while using Extina include the following:
  • Turn the canister upside down and dispense into the cap or another cool surface. Dispensing it into a hand is not recommended, as it begins to melt immediately upon contact with warm skin.
  • Gently massage the foam into the affected area, picking up only small bits of the foam at once. If your hands are warm, you might want to cool them off by rinsing in cold water and drying beforehand. If the foam still seems runny, try running the can under cold water for a few minutes.
  • If you are applying the foam to a hairy area, such as the scalp, part the hair as you go and apply the medication directly to the skin rather than the hair.
  • For the medication to work properly, it must be used as prescribed.
  • If you are unsure about anything related to dosing with Extina, please talk to your healthcare provider or pharmacist.
