Budesonide nebuliser suspension is a corticosteroid medicine used as a "controller" for asthma and COPD, reducing airway inflammation and swelling to make breathing easier and prevent flare-ups, but it won't stop an acute asthma attack. It's delivered via a nebulizer as a fine mist, providing direct treatment to the lungs for symptoms like wheezing and shortness of breath, and needs regular, daily use for effectiveness. Common brand names include

Pulmicort Respules

, and it requires a prescription, often used with a separate reliever inhaler

.

How it works

• Reduces inflammation: It's a steroid that decreases swelling and irritation in the airways.

• Prevents symptoms: By controlling underlying inflammation, it reduces the frequency and severity of asthma attacks and COPD exacerbations. 

How to use

• A doctor prescribes it in pre-filled ampoules (liquid vials).

• The liquid is poured into a nebulizer machine, which turns it into a mist for inhalation through a mask or mouthpiece.

• It's a "preventer," so you still need a fast-acting inhaler for sudden attacks.
