For asthma, the starting dose and maximum dose of Advair depends on the form you use and the severity of your asthma symptoms.

The Advair Diskus dose for adults is one inhalation (puff) in a strength of 100 mcg/50 mcg, 250 mcg/50 mcg, or 500 mcg/50 mcg. The dosage frequency (how often it’s taken) is twice per day, about 12 hours apart.

Dosage adjustments

Your doctor may need to adjust your dosage of Advair based on:

  • the severity of your symptoms
  • the condition being treated
  • if you’re taking other drugs that might interact with Advair
  • if you have serious liver disease

When you first start Advair treatment, your doctor will see how effective the drug is for you. They may adjust your dosage if needed to make sure you’re getting the desired benefits of the drug.

If you miss a dose of Advair, just skip that dose and take your next dose at its regular scheduled time. You shouldn’t take two doses of Advair to make up for a missed dose. Doing so could cause serious side effects.

If you need help remembering to take your dose of Advair on time, try using a medication reminder. This can include setting an alarm or using a timer. You could also download a reminder app on your phone.

The dosage of Advair you’re prescribed may depend on several factors. These include:

  • your age
  • the form of Advair you’re using (Advair Diskus or Advair HFA)
  • other conditions you may have (see “Dosage adjustments” under “What is Advair’s dosage?”)
