The sections below are summarized in plain English from fluticasone/salmeterol's FDA-approved prescribing information. They describe what the official label says, and are not personal medical advice.

How It Works

Advair Diskus contains two medicines. Fluticasone is a steroid that reduces swelling in your lungs. Salmeterol is a long-acting bronchodilator that relaxes the muscles around your airways, making it easier to breathe.

Serious Warnings

Long-acting beta-agonists (LABAs) like salmeterol can increase the risk of asthma-related death. Do not use Advair Diskus to treat sudden asthma symptoms. Do not use other medicines containing a LABA. Watch for signs of pneumonia if you have COPD.

Known Drug Interactions

• Strong cytochrome P450 3A4 inhibitors (e.g., ritonavir, ketoconazole): Use not recommended. The use of strong CYP3A4 inhibitors (e.g., ritonavir, atazanavir, clarithromycin, indinavir, itraconazole, nefazodone, nelfinavir, saquinavir, ketoconazole, telithromycin) with ADVAIR DISKUS is not recommended because increased systemic corticosteroid and increased cardiovascular adverse effects may occur. Ketoconazole Fluticasone Propionate: Coadministration of orally inhaled fluticasone propionate (1,000 mcg) and ketoconazole (200 mg once daily) resulted in a 1.9-fold increase in plasma...

Mechanism: Ketoconazole stops your body from clearing the medicine in the inhaler. This can lead to higher levels of the steroid in your body and may cause heart-related side effects.

The use of strong CYP3A4 inhibitors (e.g., ritonavir, atazanavir, clarithromycin, indinavir, itraconazole, nefazodone, nelfinavir, saquinavir, ketoconazole, telithromycin) with ADVAIR DISKUS is not recommended because increased systemic corticosteroid and increased cardiovascular adverse effects may occur.

Mechanism: Clarithromycin blocks the enzyme that breaks down the ingredients in your inhaler. This can cause the medicine to build up in your body and increase the risk of side effects.

The use of strong CYP3A4 inhibitors (e.g., ritonavir, atazanavir, clarithromycin, indinavir, itraconazole, nefazodone, nelfinavir, saquinavir, ketoconazole, telithromycin) with ADVAIR DISKUS is not recommended because increased systemic corticosteroid and increased cardiovascular adverse effects may occur.

Mechanism: Itraconazole stops the body from breaking down the inhaler medicine, which can lead to higher levels in your blood and more side effects.

( 7.4 ) 7.1 Inhibitors of Cytochrome P450 3A4 Fluticasone propionate and salmeterol, the individual components of ADVAIR DISKUS, are substrates of CYP3A4. Ritonavir Fluticasone Propionate: A drug interaction trial with fluticasone propionate aqueous nasal spray in healthy subjects has shown that ritonavir (a strong CYP3A4 inhibitor) can significantly increase plasma fluticasone propionate exposure, resulting in significantly reduced serum cortisol concentrations [see Clinical Pharmacology ( 12.3 )] . During postmarketing use, there have been reports of clinically significant drug...

Mechanism: Both of these products contain the same steroid medicine. Taking them together increases the amount of medicine in your body, which can lower your natural hormone levels.

May potentiate effect of salmeterol on vascular system. ( 7.4 ) 7.1 Inhibitors of Cytochrome P450 3A4 Fluticasone propionate and salmeterol, the individual components of ADVAIR DISKUS, are substrates of CYP3A4. Salmeterol: In a drug interaction trial in 20 healthy subjects, coadministration of inhaled salmeterol (50 mcg twice daily) and oral ketoconazole (400 mg once daily) for 7 days resulted in greater systemic exposure to salmeterol (AUC increased 16-fold and C max increased 1.4-fold).

Mechanism: These two products contain the same active ingredient. Taking both at once can lead to an overdose, which may cause heart or blood pressure problems.

Post-market surveillance from the FDA Adverse Event Reporting System (FAERS) captures real-world experience. Voluntary reports accumulate over the lifetime of a drug and reflect wide-ranging clinical use. The database also lists 5 documented drug interactions derived from FDA labeling, with the top-flagged interaction rated moderate severity. NADAC pricing from CMS.

Report counts do not establish causation, a FAERS entry documents a temporal association, not proof that the drug produced the outcome. Widely prescribed medications naturally accumulate more reports than niche therapies, so raw totals must be interpreted alongside total exposure. Shortage status, recall history, and patent information are separate source-record fields. This page is a public FDA/CMS registry and does not provide medical, treatment, substitution, or medication-change directions.
