- as others have mentioned, this is a GREAT idea. And as you've stated, storing your Breo Ellipta inhaler and other asthma medications in your room rather than the bathroom can help prevent exposure to excess humidity, which can potentially degrade the medications. Humidity can impact the stability and effectiveness of certain medications, especially those in powder or aerosol form, like inhalers. I like to designate a spot in my closet to keep my medications out of humidity and heat. Thank you for sharing. I hope your week is progressing well. Rebecca (team member)
