Salbutamol Inhaler

What is salbutamol?

Salbutamol is a reliever inhaler used to quickly ease breathing problems by opening the airways. It’s a bronchodialator also known by the brand names Ventolin, Airomir, Asmalal, Pulvinal, Salamol, and Salbulin[1]. 

What is salbutamol used to treat?

Salbutamol is commonly used to treat[1]: 

• Asthma 

• Chronic Obstructive Pulmonary Disease (COPD) 

• Exercise-induced bronchospasm 

• Other conditions that cause wheezing, shortness of breath, or chest tightness 

How does salbutamol work?

Salbutamol works by relaxing the muscles around the airways. It stimulates beta-2 receptors in the lungs, helping to open the air passages so you can breathe more easily[1]. 

Who can take salbutamol?

Salbutamol inhalers are suitable for most people, but certain conditions may require extra care[1]. 

Generally safe for: 

• Adults and children of all ages 

• Pregnant or breastfeeding women – but only under medical advice 

Caution is advised for people with[1]: 

• Heart conditions 

• Overactive thyroid (hyperthyroidism) 

• High blood pressure 

Please tell your doctor or pharmacist about any conditions you may have or medication you take before you start treatment, and always follow the instructions in the Patient Information Leaflet[2].  

What is the usual dose of salbutamol?

The right dose depends on your age and symptoms, but here’s what’s typical[1]: 

• Adults and children: 1 or 2 puffs when needed 

• Maximum dose: Usually up to 8 puffs in 24 hours (unless advised otherwise by a doctor) 

• Other forms like tablets or syrup may be used, especially for young children or those unable to use an inhaler 

How do you take salbutamol?

Salbutamol is most commonly used as an inhaler. Here’s how to use the pressurised metred dose device correctly[1]: 

• Shake the inhaler well 

• Breathe out fully 

• Place the mouthpiece in your mouth and seal your lips around it 

• Press the canister and inhale deeply and slowly at the same time 

• Hold your breath for about 10 seconds 

• If you need a second puff, wait 30 seconds, then repeat 

Instructions can also be found on the outer packaging of some devices or on the patient information leaflet inside the box. 

Other ways to take salbutamol include: 

• Tablets 

• Liquid syrup 

• Nebuliser solution – usually used in more severe cases 

Can you stop taking salbutamol?

Salbutamol is usually taken as needed, so it doesn’t follow a fixed schedule. However, if you find you’re using it more often than usual, speak to your doctor – this may suggest your condition is not well controlled[1]. 

What do you do if you take too much salbutamol?

Taking too much salbutamol can cause unwanted side effects, such as[1]: 

• Shakiness or tremors 

• Headaches 

• Rapid heartbeat 

• Muscle cramps 

Seek immediate medical advice if you or someone else has taken too much – especially if symptoms are severe. 

What do you do if you forget a dose?

Since salbutamol is taken when needed, you don’t have to stick to a strict schedule. If you forget to use it during symptoms, just take a puff as soon as you need it. Do not double up to make up for a missed dose[1]. 

Medicines you can and can’t take with salbutamol

Salbutamol may interact with certain medications, so always check before combining it with others. Use caution with 

• Beta-blockers (e.g., propranolol) – can reduce salbutamol’s effectiveness

• Diuretics (water tablets) – may increase risk of low potassium levels

• Other asthma medications – check for duplication or interactions 

Always inform your doctor or pharmacist about all medications and supplements you take before you start a new medicine, and follow the instructions in the Patient Information Leaflet[2].

• Headache 

• Fast heartbeat (palpitations) 

• Muscle cramps 

The serious but rare side effects include[1]:
