Whilst the use of inhaled steroids and long acting beta-adrenoceptor agonists (LABA) are recommended in asthma guidelines for the resulting improved symptom control,  concerns have been raised that salmeterol may increase the small risks of asthma deaths and this additional risk is not reduced with the additional use of inhaled steroids.  Other side effects from this drug combination may include increased blood pressure, change in heart rate, an irregular heartbeat, increased risk of osteoporosis, cataracts, and glaucoma. 
Fluticasone nasal spray controls the symptoms of hay fever or allergies but does not cure these conditions. Your symptoms will probably not begin to improve for at least 12 hours after you first use fluticasone, but it may take several days or longer before you feel the full benefit of fluticasone. Fluticasone works best when used regularly. Use fluticasone on a regular schedule unless your doctor has told you to use it as needed. Call your doctor if your symptoms get worse or do not improve after you use nonprescription fluticasone nasal spray daily for 1 week.
