Advair HFA
Advair HFA, the brand name for a combination of fluticasone propionate and salmeterol, is an inhaler prescribed to treat asthma and chronic obstructive pulmonary disease (COPD). Fluticasone is a corticosteroid that reduces inflammation in the airways, while salmeterol is a long-acting beta-agonist (LABA) that helps to relax and open the airways, making it easier to breathe. This combination therapy is designed to prevent asthma attacks and manage COPD symptoms, reducing the frequency and severity of breathing difficulties. Advair HFA is not intended for immediate relief of acute symptoms, but rather as a maintenance therapy to help control and prevent symptoms over the long term.
Advair HFA is available by prescription and can be found in most pharmacies. It is dispensed as an inhaler, with different strengths available to suit the needs of various patients. Advair HFA is not classified as a controlled substance, meaning it does not have a high potential for abuse or dependence. However, it is essential to use it as directed by a healthcare provider to ensure optimal management of asthma or COPD.
Advair HFA belongs to two formal drug classes:
- Corticosteroid (Fluticasone): Reduces inflammation in the airways.
- Long-acting beta-agonist (LABA) (Salmeterol): Relaxes and widens the airways, making breathing easier.
Informally, it is often referred to as a "maintenance inhaler" or "combination inhaler" for asthma and COPD. These classes and informal terms highlight its dual action in both controlling inflammation and maintaining open airways for better respiratory function.

Frequently Asked Questions
How long does it take for Advair HFA to start working?
Advair HFA helps control asthma and COPD symptoms over time, but it is not intended for immediate relief. It may take several days to a few weeks of regular use to see the full benefits. For sudden symptoms, use a rescue inhaler as prescribed.
Can I stop using Advair HFA once my symptoms improve?
No, you should continue using Advair HFA as prescribed, even if your symptoms improve. Stopping the medication abruptly can lead to worsening symptoms. Always consult your healthcare provider before making any changes to your treatment plan.
What should I do if I miss a dose?
If you miss a dose, take it as soon as you remember. If it’s almost time for your next dose, skip the missed dose and continue with your regular schedule. Do not double the dose to make up for the missed one.
Can I use Advair HFA with other inhalers?
Yes, but you should consult your healthcare provider before using multiple inhalers. It is common to use a rescue inhaler in addition to Advair HFA, but other medications should be reviewed for potential interactions.
How should I store Advair HFA?
Store Advair HFA at room temperature, away from moisture and heat, and do not puncture or expose the inhaler to open flames. Keep the cap on when not in use to protect the mouthpiece from dust and debris.
Is it safe to use Advair HFA long-term?
Advair HFA is generally safe for long-term use when prescribed for asthma or COPD. However, long-term use should be monitored by your healthcare provider to manage any potential side effects, such as infections or bone loss.
Comprehensive Drug Guide
How Does Advair HFA Work?
Advair HFA works by combining the effects of fluticasone and salmeterol. Fluticasone reduces inflammation in the airways, which helps prevent the swelling and irritation that can trigger asthma symptoms and exacerbate COPD. Salmeterol, on the other hand, acts on beta-2 receptors in the lungs, causing the muscles around the airways to relax and the airways to open wider. This dual action helps prevent asthma attacks and reduces the frequency of COPD exacerbations by keeping the airways open and reducing inflammation over time.
Common Dosages
Advair HFA is typically available in the following strengths:
- 45 mcg/21 mcg per actuation
- 115 mcg/21 mcg per actuation
- 230 mcg/21 mcg per actuation
The dosage prescribed depends on the severity of the condition and the patient's response to treatment. The healthcare provider will determine the appropriate strength and dosing frequency.
The typical dosing for Advair HFA is two inhalations twice daily, approximately 12 hours apart. It is important to follow the dosing schedule as prescribed and not to exceed the recommended dose. The inhaler should be shaken well before use, and patients should rinse their mouth with water (without swallowing) after each use to reduce the risk of developing oral thrush.
Typical Dosing
FDA Approved Indications
Advair HFA is FDA-approved for:
- Asthma: For the maintenance treatment of asthma in patients 12 years of age and older.
- Chronic Obstructive Pulmonary Disease (COPD): Including chronic bronchitis and emphysema, to improve lung function and reduce the frequency of exacerbations.
There are no widely recognized off-label uses for Advair HFA, as its indication is specifically for the long-term management of asthma and COPD.
Who Shouldn't Take Advair HFA?
Advair HFA should not be used in individuals who have:
- A known hypersensitivity to fluticasone, salmeterol, or any other components of the inhaler.
- Acute episodes of asthma or COPD requiring intensive treatment (e.g., a rescue inhaler should be used instead).
It should also be used with caution in patients with certain medical conditions, such as heart disease, high blood pressure, diabetes, or thyroid disorders. Discuss your full medical history with your healthcare provider before using Advair HFA.
Advice From The Pharmacist
When using Advair HFA, it is important to use the inhaler regularly as prescribed, even when you are feeling well, to maintain control of your asthma or COPD. Do not use it as a rescue inhaler for sudden symptoms—keep a fast-acting bronchodilator on hand for those situations. Shake the inhaler well before each use, and rinse your mouth after inhalation to prevent oral thrush. If you miss a dose, take it as soon as you remember, but do not double up on doses. If you have any questions about how to use the inhaler or manage your condition, consult your healthcare provider or pharmacist.
Side Effects of Advair HFA
Common Side Effects
Common side effects of Advair HFA include headache, throat irritation, hoarseness, and cough. More serious side effects, though less common, can include signs of allergic reactions (e.g., rash, itching, swelling), worsening breathing problems, or signs of infection (e.g., fever, chills). If you experience any of these serious symptoms or if your asthma or COPD symptoms do not improve or worsen, seek medical attention immediately.
Risks and Warnings of Advair HFA
The major risks associated with Advair HFA include the potential for worsening asthma symptoms or COPD if the medication is not used correctly. Long-term use of corticosteroids, even in inhaled form, can also increase the risk of infections, bone loss, and eye problems such as cataracts or glaucoma. LABAs, such as salmeterol, carry a risk of worsening asthma symptoms or leading to asthma-related deaths if not used in combination with an inhaled corticosteroid like fluticasone. Therefore, it is important to use Advair HFA exactly as prescribed and to avoid using it as a rescue inhaler.
Interactions with Advair HFA
Common Drug Interactions
Advair HFA can interact with other medications, including:
- Beta-blockers: May reduce the effectiveness of salmeterol.
- Certain antifungal and antiviral medications (e.g., ketoconazole, ritonavir): Can increase the levels of fluticasone in the blood, leading to more side effects.
- Other corticosteroids: Using multiple corticosteroid medications can increase the risk of side effects.
Always inform your healthcare provider of all medications, supplements, and herbal products you are taking to avoid potential interactions.
Alternatives to Advair HFA
Alternative treatments for asthma and COPD management include other combination inhalers, such as:
- Symbicort (budesonide/formoterol)
- Dulera (mometasone/formoterol)
- Breo Ellipta (fluticasone/vilanterol)
Single-agent inhalers, such as albuterol (a short-acting bronchodilator) or inhaled corticosteroids alone (e.g., Qvar, Pulmicort), may also be options depending on the patient's condition. Your healthcare provider can help determine the best treatment based on your specific needs.
