What Is AirDuo Digihaler?
AirDuo Digihaler (fluticasone propionate and salmeterol) is a combo dry-powder asthma inhaler. It contains two different medications: fluticasone propionate and salmeterol.
Fluticasone propionate is an inhaled corticosteroid (ICS) that lessens airway swelling. Salmeterol, on the other hand, is a long-acting beta-agonist (LABA), which works by relaxing the airways.
AirDuo Digihaler is available as a prescription dry powder for oral inhalation.

What Is AirDuo Digihaler Used For?
AirDuo Digihaler is a long-term treatment option for asthma.
In the United States (U.S.), millions of adults and children are living with asthma. People with asthma have swollen lung airways that can cause the following symptoms: coughing, wheezing, and breathing difficulties.
How to Use AirDuo Digihaler
Since directions might vary for different inhalers, carefully read the directions and packaging label on the container.
In general, however, you don't need to prime or spray the medication away from you if AirDuo Digihaler is new or if you haven't used this inhaler in a while.
AirDuo Digihaler is typically used twice daily without a spacer. When using this inhaler, keep in mind that the medication is a fine, dry powder. So, you may not feel or taste the medicine.
The following are additional steps for using AirDuo Digihaler.
- Keep the new inhaler inside its foil packaging until you're ready to use it.
- Hold the inhaler upright and open the yellow cap all the way until you hear a clicking sound. If you hear a clicking sound, then the inhaler is "activated" and ready to give you a dose. Don't open the yellow cap to expose the mouthpiece until you're ready to use the inhaler.
- Breathe out as much air from your lungs as you can.
- Tightly seal your lips around the mouthpiece—making sure to not block the vent above the mouthpiece.
- Breathe in quickly and deeply through your mouth for the medication to go into your lungs.
- Remove the inhaler from your mouth.
- Hold your breath for as long as you can for up to 10 seconds—if possible.
- Tightly cover the mouthpiece with the yellow cap. Make sure to do this after each inhalation.
- Rinse your mouth with water and spit after each use.
- When you have 20 doses left, you will notice a red color in the dose counter. Request a refill at this time. Once there is a 0 in the dose counter, you are out of doses.
Once you receive AirDuo Digihaler from the pharmacy, store it in a cool and dry place between 59 degrees to 77 degrees Fahrenheit (F). Protect the inhaler from extreme heat, cold, or moist conditions. If the inhaler is dirty, wipe it with a dry cloth or tissue. Don't wash or expose the inhaler to water.
After removing the inhaler from its foil packaging, the medication will only be good for 30 days from the opened date. If you haven't removed the inhaler from its foil packaging, then the medication will be good until the expiration date on the container. When you are ready to discard an empty or expired AirDuo Digihaler, the inhaler contains lithium-manganese dioxide batteries. So, don't place it in your regular garbage. You will need to throw the inhaler away according to local and state regulations.
If you're going to travel with AirDuo Digihaler, become familiar with your final destination's regulations. In general, however, keep the original container from the pharmacy, with your name on it. Also, have a copy of your AirDuo Digihaler prescription available. Since the AirDuo Digihaler device contains lithium-manganese dioxide batteries, you will also need to carry the inhaler in your carry-on bag.
The Food and Drug Administration (FDA) only approved AirDuo Digihaler as a long-term treatment option for asthma.
There are several other inhaler devices, which also contain fluticasone and salmeterol. In addition to asthma, these inhalers (e.g., Advair Diskus, Wixela) may also be used for another lung condition called chronic obstructive pulmonary disease (COPD).
How Long Does AirDuo Digihaler Take to Work?
You might notice some improvement in your symptoms as soon as 15 minutes of using AirDuo Digihaler. The medication, however, typically requires one to two weeks for maximum effects.
What Are the Side Effects of AirDuo Digihaler?
Side effects are possible with AirDuo Digihaler.
This is not a complete list of side effects, and others may occur. A healthcare provider can advise you on side effects. If you experience other effects, contact your pharmacist or a healthcare provider. You may report side effects to the FDA at fda.gov/medwatch or 1-800-FDA-1088.
Common Side Effects
Common side effects with AirDuo Digihaler include:
Severe Side Effects
Severe side effects are possible with AirDuo Digihaler. Get medical help right away if you experience the following serious side effects:
- Severe allergic reaction: If you have a severe allergic reaction to AirDuo Digihaler, you may experience symptoms of rash, swelling, and breathing problems.
- Adrenal insufficiency: Adrenal insufficiency is also sometimes known as Addison's disease. People with this medical condition don't make enough of certain hormones, such as cortisol. If you have adrenal insufficiency, you might experience symptoms of low blood pressure, weakness, nausea, and vomiting.
- Bone loss: AirDuo Digihaler is linked to bone loss, which might raise the likelihood of having osteoporosis. Risk factors for osteoporosis may include family history, inactivity, and certain medications (e.g., steroids and anti-seizure drugs). If you have these risk factors, your healthcare provider may want to closely monitor your bone mineral density (BMD).
- Eye problems: AirDuo Digihaler might raise your risk for eye problems, such as glaucoma (high eye pressure) and cataracts (cloudy eyesight). Be alert for any vision changes.
- Heart-related effects: Some heart-related effects with AirDuo Digihaler may include high blood pressure, chest pain, fast heartbeat, or abnormal heartbeat.
- Infections: AirDuo Digihaler might suppress your immune system, which is the body's defense system. Suppressing your immune system may raise the likelihood of infections. If you suspect that you might have symptoms of an infection, notify your healthcare provider.
- Slow growth rate in children: AirDuo Digihaler might slow down the growth rate in children. To minimize this side effect, your healthcare provider will start your child on the lowest effective dose. They will also closely monitor your child for side effects.
- Tightening airways: In some people, AirDuo Digihaler might cause sudden breathing problems.
Long-Term Side Effects
Long-term use of AirDuo Digihaler is linked to the following side effects:
- Bone loss
- Eye problems
- Slow growth rate in children

Your healthcare provider might slightly modify (change) your AirDuo Digihaler treatment or other medications under the following situations:
People with diabetes: Although rare, AirDuo Digihaler is linked to high blood sugar. You might need to monitor your blood sugar closely, and your healthcare provider will adjust your diabetes-related medications accordingly.
People with liver problems: The liver is responsible for clearing out fluticasone and salmeterol from the body. In people with liver impairment, higher amounts of these medications might be in the body. Therefore, your healthcare provider may closely monitor you for side effects and adjust the medication dose accordingly.
People with medical conditions of the heart or brain: If you have medical conditions of the heart or brain, AirDuo Digihaler might worsen your symptoms, which may include seizures, abnormal heart rate, fast heartbeat, and abnormal blood pressure. Your healthcare provider will closely monitor you for worsening heart or brain-related medical conditions.
People with risk factors for osteoporosis: Risk factors for osteoporosis include family history, inactivity, and certain medications (e.g., steroids and anti-seizure drugs). If you use AirDuo Digihaler and have multiple risk factors for osteoporosis, your healthcare provider will closely monitor your bone mineral density (BMD).
Pregnant parents: There are no clinical trials on AirDuo Digihaler or its individual ingredients in pregnant parents. Not having well-controlled asthma, however, is linked to a higher risk of negative effects on the pregnant parent and unborn fetus. Parents might experience preeclampsia, a condition of high blood pressure during pregnancy. Newborn babies, on the other hand, might have low birth weights. If you have any questions or concerns about using AirDuo Digihaler during your pregnancy, talk with your healthcare provider.
Nursing parents: Experts expect very small amounts of fluticasone or salmeterol to be present in breast milk. Therefore, negative effects on the nursing baby are unlikely.
Children: AirDuo Digihaler might slow down the growth rate in children. To limit this side effect, your healthcare provider will use the lowest effective dose. They will also monitor your child for side effects.
If you accidentally forgot your AirDuo Digihaler dose, skip the missed dose and take the following dose at your next scheduled time. Don't try to double up to make up for the missed dose.
Try to find ways to consistently remember to take your medication. Missing too many AirDuo Digihaler doses might raise your risk of asthma attacks.
Overdose: What Happens If I Take Too Much AirDuo Digihaler?
Symptoms of too much fluticasone may include:
- High blood pressure
- High blood sugar
- Mood changes
- Tiredness or low energy
Symptoms of too much salmeterol might include:
- Abnormal heart rhythm
- Blood pressure changes
- Chest pain
- Dry mouth
- Fast heart rate
- Muscle cramps
- Tiredness or low energy
This is not a complete list of possible overdose symptoms with AirDuo Digihaler. If you suspect that you're experiencing life-threatening side effects, seek immediate medical attention.

What Are Reasons I Shouldn’t Take AirDuo Digihaler?
Before using AirDuo Digihaler, talk with your healthcare provider if the following applies to you.
- Severe allergic reaction: If you have a severe allergic reaction to AirDuo Digihaler, milk, or any of the inhaler's other components (ingredients), this medication isn't an ideal option for you.
- Asthma attack: If you're experiencing an asthma attack, AirDuo Digihaler isn't intended for immediate symptom relief. During an asthma attack, use a rescue inhaler to quickly relieve symptoms.
- Pregnant parents: There are no clinical studies for AirDuo Digihaler in pregnant parents. Not having well-controlled asthma, however, is linked to negative effects on pregnant parents and the unborn fetus. Talk with your healthcare provider to weigh the benefits and risks of using AirDuo Digihaler during pregnancy.
- Nursing parents: The small amounts of fluticasone and salmeterol in breastmilk are unlikely to cause negative effects on nursing babies. Therefore, experts find these inhaled medications acceptable while nursing.
- Children: The FDA approved AirDuo Digihaler as a long-term treatment option for asthma in children 12 years and older. AirDuo Digihaler, however, might slow down the growth rate in children. Therefore, your healthcare provider will use the lowest effective dose and monitor your child for side effects.
- Older adults: Older adults—people over 65 years of age—and younger adults didn't experience safety and effectiveness differences with AirDuo Digihaler.
What Other Medications Interact With AirDuo Digihaler?
Use caution when taking AirDuo Digihaler with the following medications:
- Beta-blockers: Beta-blockers are usually used for heart-related medical conditions. In general, there are two types of beta-blockers, heart-specific and non-heart-specific. The non-heart-specific beta-blockers (e.g., carvedilol) might worsen asthma symptoms. Therefore, if necessary, healthcare providers may want to consider a heart-specific beta-blocker, such as Toprol XL (metoprolol succinate).
- Long-acting beta-agonists (LABAs): AirDuo Digihaler contains salmeterol, which is a LABA. Combining AirDuo Digihaler with other LABAs—like Striverdi (olodaterol)—raises the risk of an overdose.
- Monoamine oxidase inhibitors (MAOIs): MAOI use within the last two weeks might increase the likelihood of side effects with AirDuo Digihaler. An example of an MAOI is selegiline, which is a treatment option for depression or Parkinson's disease.
- Tricyclic antidepressants (TCAs): Similar to MAOIs, TCA use within the previous two weeks raises the risk of side effects with AirDuo Digihaler. An example TCA is amitriptyline, which is a treatment option for mental health conditions and nerve pain.
- Strong CYP3A4 inhibitors: CYP3A4 is a protein in the liver that's responsible for breaking down and clearing out fluticasone and salmeterol from the body. Strong CYP3A4-inhibiting medications—like the clarithromycin antibiotic—prevent the protein from working as well. The build-up of fluticasone and salmeterol levels in the body raises the risk of side effects.
- Diuretics (water pills): When combined with AirDuo Digihaler, non-potassium-sparing water pills—like loop or thiazide diuretics—might cause low potassium levels in the body. Symptoms of low potassium may include abnormal heartbeat, muscle weakness, spasms, and tingling or numbness sensation.
This isn't a complete list of medication interactions with AirDuo Digihaler. For more detailed information about drug interactions with AirDuo Digihaler, talk with your pharmacist or healthcare provider.
What Medications Are Similar?
