Below are answers to some commonly asked questions about Advair’s dosage.

I’m switching from Symbicort to Advair. What dose conversion might my doctor prescribe?

The dose conversion that your doctor prescribes will depend on certain factors. These include your current dosage of Symbicort (budesonide/formoterol) and the condition you’re taking the drug to treat. Your doctor will determine the equivalent dose of Advair that’s right for you. They’ll also advise how to take your Advair dosage.

To learn more about what your dose conversion will be with Advair, talk with your doctor. For information about how Advair and Symbicort otherwise compare, see this article.

How many Advair doses per inhaler are there?

For Advair Diskus, there are 60 doses (60 puffs) per Diskus inhaler. For Advair HFA, there are either 30 doses (60 puffs) or 60 doses (120 puffs), depending on the canister size. Advair Diskus and Advair HFA inhalers have a counter that tells you how many doses are left in the device.

If you have questions about how many doses your Advair inhaler comes with or how many doses are left, talk with your doctor or pharmacist.

The Advair dosage your doctor prescribes will depend on several factors. These include:

  • the type and severity of the condition you’re using Advair to treat
  • the form of Advair you’re prescribed
  • your age

You should take Advair according to your doctor’s instructions.

You’ll take your Advair Diskus or Advair HFA dose as puffs, which you inhale. The drugs contain the same active ingredients. However, they come in different types of inhalers. Advair Diskus comes as an inhaler containing powder that you breathe in deeply. Advair HFA is an aerosol that delivers a spray of medication that you breathe in as you press down on the top of the canister.

Your doctor will show you how to use your inhaler correctly. You can also view the manufacturer’s instructions on how to use Advair Diskus or Advair HFA.

Be sure to always rinse your mouth with water right after taking Advair. After rinsing, spit out the water. Do not swallow it. Rinsing each time will help reduce your risk of thrush, a fungal infection in your mouth and throat. (Thrush is a side effect of Advair. To learn more, see this article.)

Advair is typically taken twice per day. It’s best to take your doses about 12 hours apart, around the same times each day. This helps maintain a steady level of the drug in your body so Advair can work effectively.

If you have questions about how to use Advair, talk with your doctor or pharmacist.

ACCESSIBLE DRUG LABELS

If you’re having trouble reading your prescription label, talk with your doctor or pharmacist. Some pharmacies offer labels with large print, braille, or a code you scan with a smartphone to convert text to speech. If your local pharmacy doesn’t have these options, your doctor or pharmacist might be able to recommend a pharmacy that does.

If you miss a dose of Advair Diskus or Advair HFA, skip that dose. Wait and take your next dose at the usual time. Do not take more than one Advair dose at a time. This can increase your risk of serious side effects. (To learn more about side effects of Advair, see this article.)

To help make sure that you don’t miss a dose, 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.

If you use more Advair than your doctor prescribes, you may develop serious side effects. It’s important that you don’t use more Advair than your doctor advises.

Symptoms of an overdose

Overdose symptoms of Advair can include:

If you take more than the recommended amount of Advair or accidentally take extra doses

Call your doctor right away if you believe you’ve taken too much drug. This includes if you accidentally take two or more doses of Advair. (Keep in mind that each dose of the drug your doctor prescribes will include a certain number of puffs from the prescribed inhaler.)

Another option is to call America’s Poison Centers at 800-222-1222 or use its online tool. If you have severe symptoms, immediately call 911 or your local emergency number, or go to the nearest emergency room.

The dosages in this article are typical dosages provided by the drug manufacturer. If your doctor recommends Advair for you, they will prescribe the dosage that’s right for you. Always follow the dosage that your doctor prescribes for you.
