Salbutamol is a short-acting beta-2 agonist that relaxes the smooth muscle in the airways, allowing them to widen and making breathing easier. It is typically administered via a metered-dose inhaler or a nebuliser, and it is primarily used for quick relief of acute asthma symptoms rather than long-term control. Correct inhaler technique is essential for effectiveness; patients should be shown the proper method and advised to carry their rescue inhaler at all times. Regular review ensures the inhaler remains appropriate and effective for the individual.

Proper technique maximises drug delivery to the lungs. Shake the inhaler, exhale fully, place the mouthpiece between your lips, start a slow inhalation and press the canister once, continue to inhale deeply, then hold your breath for several seconds before exhaling. Spacer devices can improve delivery for children and anyone who struggles with timing. Rinse your mouth after use if advised. Regular inhaler checks with a healthcare professional help ensure ongoing effectiveness and reduce wasted doses.

Regular review with a clinician is important if you rely on your salbutamol inhaler more frequently than expected, if nighttime symptoms occur, or if exercise triggers worsening breathing. Keep a record of inhaler use and symptom patterns to help guide treatment adjustments. If you experience sudden severe breathlessness, confusion, or bluish lips, treat as an emergency and seek immediate medical attention. For ongoing control, your clinician may recommend preventer inhalers, action plans, and allergy or trigger assessment.
