Is Advair Diskus the Same as Advair HFA?

Is Advair Diskus the Same as Advair HFA? Key Differences Explained

Key Takeaways

  • Advair Diskus and Advair HFA inhalers contain the same active ingredients (fluticasone propionate and salmeterol) but use different delivery systems and cannot be substituted for each other.
  • Advair Diskus is used to treat asthma and chronic obstructive pulmonary disease (COPD) in patients 4 years and older, while Advair HFA is only approved for asthma in patients 12 years and older.
  • The two formulations have different dosing strengths and ways to inhale them that should be demonstrated by your healthcare provider before you start using them.
  • Neither formulation should be used as a rescue inhaler for sudden breathing problems. You will need to carry a separate short-acting bronchodilator like albuterol (Ventolin HFA) for that.

Are Advair Diskus and Advair HFA the Same Medication?

Advair Diskus and Advair HFA are combination medications that contain the same active ingredients. Both prescription drugs include fluticasone propionate, an inhaled corticosteroid that reduces inflammation, and salmeterol, a long-acting beta-agonist that relaxes airway muscles. However, the FDA considers these separate medications that cannot be substituted without physician approval.

The main difference is in their delivery systems. Advair Diskus is a fluticasone propionate and salmeterol inhalation powder that requires breath-activated administration, while Advair HFA is a metered-dose inhaler that delivers these medications through an inhalation aerosol.

You should not switch between formulations without guidance from your healthcare provider. Doing so could lead to poor symptom control or adverse effects.

Active Ingredients Comparison

Both Advair formulations contain the same two-drug combination of fluticasone propionate and salmeterol. Fluticasone propionate serves as an inhaled corticosteroid that reduces airway inflammation, swelling, and mucus production associated with asthma and chronic obstructive pulmonary disease (COPD).

Salmeterol is a long-acting beta-agonist bronchodilator that relaxes smooth muscle around the airways for up to 12 hours.

When used consistently, both active ingredients work together to improve lung function, reduce asthma or COPD symptoms, and decrease the frequency of flare-ups. However, neither component provides immediate relief for sudden breathing problems, which is why patients must always carry a separate rescue inhaler containing short-acting bronchodilators like albuterol.

FDA-Approved Uses and Indications

Advair Diskus is approved to treat asthma symptoms in patients 4 years and older. It is also approved for chronic obstructive pulmonary disease (COPD) maintenance treatment in adults, which includes chronic bronchitis and emphysema.

Advair HFA is only approved for asthma treatment in patients 12 years and older. This formulation is not approved to treat COPD or any related conditions.

Both oral inhalations are intended for long-term maintenance therapy to control symptoms and prevent exacerbations. Neither should be used to treat acute asthma attacks or sudden breathing problems.

Dosing Strengths and Administration

Advair Diskus Strengths

Advair Diskus is available in three strength combinations: 100/50 mcg, 250/50 mcg, and 500/50 mcg of fluticasone propionate and salmeterol per inhalation. The standard recommended dosage involves one inhalation twice daily, approximately 12 hours apart. COPD patients will typically use the 250/50 mcg strength twice daily for maintenance therapy and to reduce COPD exacerbations.

Pediatric patients between 4-11 years usually begin with the 100/50 mcg strength, with dose adjustments based on asthma control and individual response. This is typically the maximum dose for children as well. Regular monitoring of your child’s growth is essential, as inhaled corticosteroids may cause slowed growth in some children.

Advair HFA Strengths

Advair HFA comes in three different strength combinations: 45/21 mcg, 115/21 mcg, and 230/21 mcg per actuation. The standard recommended dosage is two puffs twice daily. You should wait at least one minute between puffs when taking multiple inhalations.

You will typically start with the smallest dosage that provides adequate control. Your healthcare providers will adjust the strength based on symptom management and any adverse effects that occur.

Administration Technique Differences

Proper administration technique is important for both formulations. Using Advair Diskus involves opening the device, sliding the lever until it clicks, and then breathing in deeply and forcefully through the mouthpiece. You should not breathe into the device, shake it, or use it if moisture is inside the inhaler.

After inhaling a dose, you should hold your breath for around 10 seconds, then exhale slowly. The device should be closed immediately after use, and you should rinse your mouth thoroughly with water and spit to prevent throat irritation and reduce the risk of oral thrush or yeast infection.

Advair HFA requires shaking the inhaler well before each use, removing the cap, and exhaling fully before placing lips around the mouthpiece. You will press down on the canister while beginning a slow, deep inhalation, continuing to breathe in slowly and deeply. After holding your breath for 10 seconds, wait at least one minute before taking a second puff if prescribed.

Both techniques require mouth rinsing after use to reduce the risk of fungal infection in the mouth and throat. Contact your healthcare provider if you have any questions about how to use your Advair Diskus or HFA inhaler.

Side Effects and Safety Profile

Both Advair inhalers have similar side effects because they contain the same active ingredients. Common side effects include headache, throat irritation, thrush, upper respiratory tract infections, nausea, vomiting, muscle cramps or pain, bone pain, and hoarseness. These effects typically occur more frequently when you first begin treatment and go away after your body gets used to the medication.

Serious side effects can include increased infection risk, high blood pressure, fast or irregular heartbeat, chest pain, vision problems, and sudden breathing problems.

Some people may experience allergic reactions to either formulation. However, Advair Diskus contains milk proteins that could trigger serious allergic reactions in individuals with severe milk allergies. Signs of a serious allergic reaction include rash, hives, swelling of the face or throat, and breathing difficulties requiring immediate medical attention.

Long-term use of inhaled corticosteroids may affect the immune system, increase the risk of infections, and possibly decrease bone density. Children using either formulation require monitoring for growth effects, as higher doses of inhaled corticosteroids can cause slowed growth that may not be fully reversible.

Both formulations can interact with other medications, particularly those affecting the cardiovascular system or other drugs metabolized by similar pathways. Be sure to inform healthcare providers about all prescription drugs, over-the-counter medications, and supplements before starting either Advair formulation to help avoid serious drug interactions.

Important Safety Considerations

Neither Advair formulation should be used as rescue medication for sudden breathing problems or asthma attacks. You must carry a separate short-acting rescue inhaler like albuterol for immediate relief of breathing difficulties.

Both formulations require consistent twice-daily use to be effective in asthma management and COPD control. They are both typically taken around the same times each day, ideally 12 hours apart. Missing doses regularly can increase your risk of exacerbations.

If a missed dose occurs, take it as soon as you remember, unless it’s almost time for the next dose. Never double your dose to make up for a missed one, as this could increase the risk of adverse effects. If you are switching from oral steroids to inhaled therapy, healthcare providers must carefully monitor you for signs of adrenal gland problems.

Regular appointments with your healthcare providers are important for both formulations. This includes checking lung function, assessing symptom control, monitoring for side effects, and adjusting treatment as needed. Children require additional monitoring for growth effects and developmental milestones.

Do not stop either Advair formulation suddenly without talking to your provider, as this could lead to worsening symptoms or serious complications.

Both formulations can increase your risk of serious respiratory infections, so call your doctor if you develop fever, increased mucous production, or worsening breathing symptoms that don’t respond to your rescue medication.

Frequently Asked Questions

Can I switch from Advair Diskus to Advair HFA on my own?

No, you should never switch between Advair formulations without consulting your healthcare provider. Despite containing the same active ingredients, they have different delivery mechanisms, dosing strengths, and administration techniques. Making this change without talking to your provider could result in poor symptom control or medication errors.

Which Advair formulation is more effective for treating asthma?

Both formulations are equally effective for asthma control when used properly, according to clinical studies. The choice between them depends more on factors like age, hand coordination, lung function, and personal preferences. A licensed healthcare professional will recommend the most appropriate formulation based on your specific medical conditions and physical capabilities.

Why isn’t Advair HFA approved for COPD like Advair Diskus?

The FDA approval process requires separate clinical trials for different formulations and medical conditions. Advair Diskus underwent specific clinical studies demonstrating its safety and effectiveness for COPD treatment and reducing COPD exacerbations. Advair HFA’s studies only focused on asthma treatment and not COPD. This means only Advair Diskus has been proven safe and effective for COPD patients through the FDA process.

Do both Advair formulations require the same storage conditions?

Both inhalers should be stored at room temperature between 68°F to 77°F (20°C to 25°C), but they have some different requirements. Advair Diskus must be kept completely dry and should never be exposed to moisture, which can affect the powder medication. The device should remain in its original foil pouch until ready for use. Advair HFA should be protected from extreme heat to prevent canister damage or potential explosion, and the metal canister should never be punctured or thrown into fire, even when empty.

What happens if I accidentally take too much of either Advair formulation?

Taking higher doses than your doctor prescribed could lead to increased side effects such as fast or irregular heartbeat, tremor, headache, nervousness, or increased blood pressure. If you accidentally take extra doses, contact your healthcare provider or poison control immediately.
