Frequently asked questions

What is albuterol used for?

Albuterol is a rescue bronchodilator that quickly relieves asthma and COPD symptoms by relaxing airway muscles during an attack. Works within minutes.

How quickly does albuterol work?

Typically begins within 1–5 minutes of inhalation. Peak effect at 30–60 minutes. Relief generally lasts 4–6 hours.

How often can I use my albuterol inhaler?

1–2 puffs every 4–6 hours as needed. If needed more than 2 days per week, consult your doctor about additional maintenance therapy.

Why does albuterol cause shaking?

Albuterol stimulates beta receptors in skeletal muscles as well as airways, causing tremors. A common and usually harmless side effect that lessens with time.

What is the difference between albuterol and a steroid inhaler?

Albuterol works immediately to open airways during an attack. Steroid inhalers (like fluticasone) are daily preventers that reduce inflammation over time. Both are often needed together.
