What is a salbutamol inhaler?
A salbutamol inhaler is a fast-acting reliever treatment used to ease symptoms of asthma and other airway conditions like chronic obstructive pulmonary disease (COPD). It works quickly to open the airways, helping you breathe more easily during episodes of wheezing, shortness of breath, or chest tightness.
It's most commonly used as a reliever inhaler, meaning it's taken when symptoms occur rather than on a fixed daily schedule.
What’s the difference between an inhaler and an EasyHaler?
Inhaler is a general term for devices used to deliver medication to the lungs. There are different types, including:
- Pressurised metered-dose inhalers (pMDIs): these release a spray when pressed.
- Dry powder inhalers (like EasyHaler): these release medication when you inhale. EasyHalers don’t require coordination between pressing and breathing in, which some people find easier to use.
This product is a pMDI. However, we also provide a salbutamol EasyHaler is this device is more suited to your needs.
How does salbutamol work?
A salbutamol inhaler is a bronchodilator inhaler that delivers salbutamol directly into the lungs. Each dose typically contains 100 micrograms of medication, with around 200 doses per inhaler.
Salbutamol is one of the most widely used treatments for asthma symptom relief and belongs to a group of medicines called short-acting beta-2 agonists (SABAs).
It works by relaxing the muscles around the airways, causing them to widen. This improves airflow and relieves symptoms like:
- wheezing
- shortness of breath
- chest tightness
Because of how quickly salbutamol works, it can be used for both immediate relief as well as preventing symptoms brought on by exercise.
How to use your salbutamol inhaler
Using your inhaler correctly ensures the medication reaches your lungs effectively, providing your with faster relief.
When using your salbutamol inhaler:
- Shake the inhaler well.
- Breathe out gently.
- Place the mouthpiece between your lips.
- Press the inhaler while breathing in slowly.
- Hold your breath for a few seconds.
Your healthcare provider may recommend using a spacer device to improve delivery.
Salbutamol inhaler dosage for adults
You should always follow your prescribed dosage.
The typical dosage for a salbutamol inhaler is:
- 1–2 puffs as needed for symptom relief.
- May be used before exercise if advised.
If you need to use your inhaler more frequently than usual, this may indicate your condition is not well controlled.
How to clean your inhaler
To maintain a clean and effective inhaler:
- Remove the canister from the plastic casing.
- Rinse the plastic casing in warm water.

Regular cleaning helps prevent blockage.
How effective is a salbutamol inhaler?
