Salmeterol

Key points

• Salmeterol is a controller bronchodilator, not a rescue inhaler.
• In asthma, long-acting beta-2 agonist treatment must follow the prescribed anti-inflammatory controller plan rather than being used alone.
• Correct device technique and review of increasing reliever use are essential to safe respiratory care.

Listings are for comparison only; suitability and supply depend on clinician and pharmacy checks, the diagnosed condition and the prescribed inhaler device.

What salmeterol is used for

Salmeterol may be used in maintenance treatment for asthma or chronic obstructive pulmonary disease. Combination and single-ingredient inhalers have different roles.

How it works

Salmeterol stimulates beta-2 receptors and relaxes airway smooth muscle for an extended period. It does not directly treat airway inflammation and should not be relied on for sudden symptoms.

Important safety checks

A clinician or pharmacist should confirm inhaler technique, current reliever and controller use, and whether ingredients are duplicated across inhalers. Heart-rhythm problems, thyroid disease, diabetes and low potassium risk may affect monitoring.

When to seek urgent care

Follow the prescribed action plan. Seek emergency help for severe breathlessness, difficulty speaking, blue or grey lips, confusion, exhaustion, chest pain, or symptoms that do not improve with the prescribed rescue treatment.
