which inhaler to take first
1 If more puffs are prescribed, the ideal is to wait between doses.  For bronchodilators that are short-acting beta agonists, it is best to wait 3 to 5 minutes. These fast-acting inhalers begin to open your airways quickly. When you wait after your first dose, the next doses can go deeper into your lungs. See âHow to Sequence Inhalersâ .
