Magnesium does all the heavy lifting in this infusion to get you breathing better during an asthma flare-up. Fun fact – Magnesium is so well-studied in asthma that most ER departments give a magnesium infusion in addition to nebulizers and steroids. If your flare-up is mild to moderate or you want to prevent a flare-up, schedule with us. If your flare-up is severe, please go to the emergency room.
