How long does advair disqus 250/50 take to completely relieve lung air trapping symptoms due to allergy??

Variable Times: Improvement in asthma control following administration of Advair diskus (salmeterol and fluticasone) can occur within 30 minutes, although maximum benefit may not be achieved for 1 week or longer after starting treatment. Of course each individual will experience a variable time to onset and degree of symptom relief. If your asthma is more severe this medication alone might not provide adequate relief. Talk to your doctor
