No, you should not. You need to treat sudden breathing problems with a rescue medication that quickly opens up your airways. These medications include short-acting beta2-agonists (SABAs), such as albuterol sulfate (Ventolin HFA, Proventil, ProAir) and levalbuterol tartrate (Xopenex).
Pulmicort is not a rescue medication. It’s a maintenance medication. When used consistently over time, it manages asthma symptoms and helps to prevent symptom flare-ups. Pulmicort works by reducing inflammation in your lungs, which helps prevent breathing problems.
While you’ll usually take Pulmicort regularly every day, you’ll only use your rescue medication as needed. However, be sure to keep your rescue medication with you at all times, in case you need to treat sudden breathing problems.
