Fluticasone Salmeterol: a practical guide for asthma and COPD

If you’ve been prescribed fluticasone salmeterol (often sold as Advair or Seretide), this combo inhaler is meant to keep breathing problems under control, not to stop an attack immediately. It combines an inhaled corticosteroid (fluticasone) to cut inflammation and a long-acting bronchodilator (salmeterol) to keep airways open.

How it works and how to use it

Take it every day exactly as your doctor tells you. Most people use it twice daily. It comes as a disk or MDI inhaler; technique matters. Shake the inhaler if it’s the HFA type, load the disk for diskus devices, breathe out, seal your lips around the mouthpiece, inhale slowly and deeply, then hold your breath for 5–10 seconds.

Rinse your mouth and spit after each use. That small step lowers your risk of oral thrush and hoarseness. This medicine is for maintenance—if you need quick relief from sudden wheeze, use your rescue inhaler (albuterol) instead.

Common side effects and safety tips

Most side effects are mild: sore throat, hoarseness, or a yeast infection in the mouth. Rinsing helps. If you have COPD, report any sudden increase in cough or fever—some studies show higher pneumonia risk in certain COPD patients on inhaled steroids.

Salmeterol can cause tremor, a fast heartbeat, or cramps. Severe allergic reactions are rare but need emergency care. Don’t stop the inhaler suddenly without asking your doctor—stopping steroids abruptly can cause problems.

Watch for drug interactions. Strong CYP3A4 inhibitors like ketoconazole can raise salmeterol levels and increase side effects. Beta-blockers (used for heart disease) can reduce how well salmeterol works. Tell your prescriber about all medications and supplements you take.

If you’re switching inhalers, ask for a demo. For example, budesonide/formoterol (Symbicort) acts faster and can be used both as maintenance and, in some plans, as a reliever. Fluticasone/salmeterol generally works well for regular control but isn’t meant for rescue use.

Store the inhaler away from heat and moisture. Keep track of doses—many devices have counters. If you travel by plane, carry it in your hand luggage and bring a copy of the prescription if needed.

Call your doctor if symptoms get worse, you need your rescue inhaler more often, or you notice side effects like fast heartbeat, severe tremor, or signs of infection. If you have sudden severe breathing trouble, go to the emergency room.
