Albuterol: Uses, Side Effects, and How to Take It Safely
Albuterol is a short-acting medicine that relaxes muscles around the airways, making it easier to breathe. It is used to relieve wheezing, chest tightness, and breathing problems from asthma or COPD and may also be used before exercise to prevent breathing symptoms.
Albuterol is a fast-acting rescue medicine for breathing symptoms, but it does not replace daily controller medicines. Take it only as directed and ask a doctor or pharmacist if you need it often or your breathing does not improve.
