Key Takeaways
- Fluticasone-salmeterol combines a corticosteroid and a long-acting bronchodilator to manage chronic asthma and chronic obstructive pulmonary disease (COPD) symptoms effectively.
- This medication is designed for long-term maintenance and is not intended to stop an acute asthma attack or sudden breathing problems.
- Patients can significantly reduce monthly costs by opting for generic versions (like Wixela Inhub) and using the Super+ RX coupon at the pharmacy.
- Prescription discount programs like the Super+ RX coupon can help you save money on fluticasone-salmeterol and other prescriptions.
Estimated Price Comparison
Prices for maintenance inhalers can vary significantly between the brand-name version and the generic equivalent. Fluticasone-salmeterol also has some “branded generic” products available, such as Wixela Inhub. A branded generic is an off-patent medication sold under a unique, manufacturer-specific brand name; it’s cheaper than brand name products but typically more expensive than generics.

What Is Fluticasone-Salmeterol?
Fluticasone-salmeterol is a prescription combination medication used to control symptoms of asthma and chronic obstructive pulmonary disease (COPD). It is widely known by the brand name Advair, though several generic alternatives are now available. This medication is not designed for sudden symptoms; rather, it is a maintenance therapy intended to prevent breathing difficulties before they start.
To understand how this medication helps manage chronic respiratory conditions, it is helpful to look at its two active ingredients and how they function together.
Fluticasone Propionate (The Corticosteroid): Fluticasone belongs to a class of medications called corticosteroids. Its primary job is to reduce inflammation and swelling in the airways. By calming the immune response in the lungs, it prevents the airways from becoming sensitive and tight, making day-to-day breathing easier and reducing the frequency of flare-ups.
Salmeterol (The Bronchodilator): Salmeterol is a long-acting beta-agonist (LABA). While short-acting beta-agonists are used for quick relief, salmeterol works over a 12-hour period to keep the muscles around the airways relaxed. This relaxation prevents the airways from narrowing, allowing air to flow more freely into and out of the lungs.
Conditions Treated
Asthma: For adults and children (depending on the specific dosage form), fluticasone-salmeterol helps manage chronic asthma when symptoms are not controlled by an inhaled corticosteroid alone. It is typically prescribed when a healthcare professional determines that a patient needs both a steroid and a long-acting bronchodilator to maintain lung function.
COPD: For adults with COPD—a group of lung diseases that includes chronic bronchitis and emphysema—this medication is used to improve airflow and reduce the number of flare-ups (exacerbations). Regular use can help improve overall lung function and quality of life for those managing long-term obstruction.
How to Save on Your fluticasone-salmeterol Prescription
Here are several practical ways you can save money if you need a prescription for fluticasone-salmeterol — whether you have insurance or not:
- Use a prescription discount card or coupon like Super+ RX: The Super+ RX coupon uncovers discounts to help lower out-of-pocket costs for fluticasone-salmeterol. Whether it’s fluticasone-salmeterol or another medication, we want to help you save—because your well-being comes first.
- Check multiple pharmacies — cash prices can vary. Pharmacies in the same area sometimes charge different prices for the same medication. Comparing cash prices among pharmacies can help you find the cheapest option. Search for your prescription on Super.com/rx, compare prices across pharmacies, and find discounts near you.
- Consider asking for the generic form, not the brand-name form. The generic versions of fluticasone-salmeterol are often much cheaper than the brand-name versions, and work the same.
What you can do before you go to the pharmacy:
- Use a discount program like the Super+ RX coupon — print it or bring it on your phone — and ask the pharmacist or cashier to apply it to your prescription.
- Compare at least two or three pharmacies on Super.com/rx to see who offers the lowest price.
- If you are uninsured or if you have a high copay, ask your healthcare team about patient-assistance programs or reduced-cost clinics in your area.

Dosage and Administration
Taking fluticasone-salmeterol correctly is critical for it to work effectively. It comes in two primary forms: a powder inhaler (Diskus) and a metered-dose inhaler (HFA). Your healthcare professional will determine which form is best for you based on your lung function and ability to use the device.
Advair Diskus (Inhalation Powder)
The Diskus is a flat, round device containing a foil strip with blisters of powder.
- Preparation: Hold the Diskus in one hand and put the thumb of your other hand on the thumb grip. Push your thumb away from you until the mouthpiece appears and snaps into place.
- Loading the Dose: Hold the device level. Slide the lever away from you until you hear a click. This pierces the blister and makes the powder available for inhalation.
- Inhalation: Breathe out fully, away from the device. Put the mouthpiece to your lips. Breathe in quickly and deeply through your mouth. Do not breathe in through your nose.
- Holding Breath: Remove the device from your mouth and hold your breath for about 10 seconds, or as long as is comfortable, to allow the powder to settle in your lungs.
- Closing: Slide the thumb grip back toward you to cover the mouthpiece. The device will reset for the next dose.
Advair HFA (Inhalation Aerosol)
The HFA version is a traditional spray inhaler that uses a propellant.
- Preparation: Shake the inhaler well for 5 seconds before each spray. Remove the cap.
- Inhalation: Breathe out fully. Place the mouthpiece into your mouth and close your lips around it. As you start to breathe in slowly and deeply through your mouth, press down on the top of the canister to release one spray.
- Holding Breath: Continue to breathe in, then hold your breath for 10 seconds.
- Wait Time: If a second puff is prescribed, wait about 30 seconds before repeating the process.
Important: Rinsing Your Mouth
After using either the Diskus or HFA inhaler, you should rinse your mouth with water and spit it out. Do not swallow the water. This step removes any leftover steroid medication from your mouth and throat, significantly reducing the risk of developing a fungal infection in the mouth known as thrush.
Missed Dose and Overdose
- Missed Dose: If you miss a dose, skip it and take your next dose at your regular time. Do not take two doses at one time to make up for a missed one.
- Consistency: This medication works best when taken twice daily, approximately 12 hours apart, at the same times every day (e.g., 8 AM and 8 PM).
Side Effects and Safety Information
While fluticasone-salmeterol is effective for many people, it carries the risk of side effects. Most side effects are mild and manageable, but some require immediate medical attention.
Common Side Effects
These effects often diminish as your body adjusts to the medication.
- Upper Respiratory Issues: Throat irritation, hoarseness, voice changes, or coughing.
- Headache: You may experience mild headaches.
- Musculoskeletal Pain: You might experience muscle pain or bone pain.
- Nausea or Vomiting: Stomach upset may occur.
Serious Side Effects
If you experience any of the following, contact a healthcare professional immediately.
- Thrush (Fungal Infection): White patches in the mouth or throat. This is a yeast infection that can be caused by the steroid component of the inhaler.
- Pneumonia (in COPD patients): Symptoms include fever, chills, increased mucus production, or changes in mucus color.
- Reduced Bone Mineral Density: Long-term steroid use can weaken bones, increasing the risk of fractures or osteoporosis.
- Eye Problems: Glaucoma (increased pressure in the eye) and cataracts (clouding of the lens) have been reported with long-term use.
- Hypokalemia: Low potassium levels in the blood, which can cause muscle weakness or abnormal heart rhythms.
- Paradoxical Bronchospasm: Rarely, the medication can cause immediate narrowing of the airways after use. If you have trouble breathing right after using the inhaler, use your rescue inhaler and seek medical help.
Drug Interactions
Fluticasone-salmeterol can interact with other medications, potentially altering how they work or increasing the risk of side effects. Always provide a full list of medications to your pharmacist.
- Beta-Blockers: often prescribed for high blood pressure or heart conditions, these can block the effectiveness of salmeterol and may trigger severe asthma spasms.
- Strong CYP3A4 Inhibitors: Medications like ritonavir (for HIV), ketoconazole (antifungal), and clarithromycin (antibiotic) can increase the amount of fluticasone in your body because they block a liver enzyme (protein) responsible for breaking down fluticasone called CYP3A4. This can lead to increased steroid side effects.
- Diuretics: “Water pills” can lower potassium levels; combining them with this inhaler may increase the risk of hypokalemia.
Frequently Asked Questions
Does fluticasone-salmeterol cause weight gain?
Inhaled corticosteroids like fluticasone generally have a lower risk of systemic (body-wide) side effects like weight gain compared to oral steroids (like prednisone). However, weight gain is a possible side effect of long-term steroid use. If you notice unusual weight changes, discuss them with a healthcare professional.
Can I use this inhaler for a sudden asthma attack?
No. Fluticasone-salmeterol is a maintenance medication. It takes time to reduce inflammation and keep airways open. You should always carry a rescue inhaler for sudden shortness of breath or acute attacks.
Is there a generic version of Advair?
Yes. There are several FDA-approved generics. Wixela Inhub is a common generic for Advair Diskus. There are also authorized generics for Advair HFA. These contain the same active ingredients and are generally much more affordable.
Why do I need to rinse my mouth after use?
The fluticasone in the inhaler can settle on the lining of your mouth and throat. If left there, it can alter the natural balance of bacteria and yeast, leading to a fungal infection called thrush. Rinsing and spitting helps wash away the residue.
How long does it take for the medication to work?
While the salmeterol component begins working to open airways within 30 to 60 minutes, the full benefit of the medication usually takes one to two weeks of consistent daily use. It is important to avoid stopping fluticasone-salmeterol it just because you do not feel an immediate difference.
Can children use this medication?
Certain formulations (specifically Advair Diskus 100/50, 250/50, and 500/50) are FDA-approved for treating asthma in children aged 4 years and older. The HFA version is approved for children aged 12 and older. Usage should always be strictly monitored by a healthcare professional.
What is the difference between Wixela and Advair?
Wixela Inhub is a generic equivalent to Advair Diskus. They contain the exact same medicines (fluticasone and salmeterol) in the same dry powder form. The main difference is the design of the inhaler device itself and the price, with Wixela typically being less expensive.
