Salbutamol inhaler

Salbutamol is a medicine that relaxes the muscles in the airways, making it easier to breathe. It is usually taken using an inhaler and is known by brand names such as Ventolin [1].

It is a reliever (or rescue) inhaler used to ease symptoms of asthma and chronic obstructive pulmonary disease (COPD), such as coughing, wheezing and feeling breathless, and it works quickly [1]. It is available on prescription [1].

• Salbutamol is a fast-acting reliever that eases breathing problems as they happen [1].
• Using the correct inhaler technique helps the medicine reach your lungs [1].
• Needing your reliever inhaler often — for example more than a few times a week — can be a sign your condition is not well controlled, so tell your doctor or nurse [1].
• Always keep a working inhaler with you if you have asthma or COPD [1].

Salbutamol inhalers can be used by most adults and children, but they do not suit everyone [1]. Tell your prescriber if you have ever had an allergic reaction to salbutamol, or if you have certain heart conditions, an overactive thyroid, diabetes or low potassium levels, as extra care may be needed [1]. They are generally considered safe to use in pregnancy and while breastfeeding, but check with your healthcare team [1].

Use your salbutamol inhaler as your prescriber or nurse shows you and as set out in the leaflet — the number of puffs and how often depends on the person and the situation [1]. Getting the technique right matters, and a spacer device can help some people, especially children [1]. If your usual dose is not relieving your symptoms, or you are using it more than normal, get medical advice, as your treatment may need reviewing [1].

Common side effects can include feeling shaky, a faster or pounding heartbeat, headaches and muscle cramps, and these are usually mild and short-lived [1]. If your breathing gets suddenly worse straight after using the inhaler, or your usual dose does not help your symptoms, get medical help quickly [1]. Seek urgent help for signs of a serious reaction [1].

Salbutamol can interact with some medicines, including other treatments for breathing problems, certain heart and blood pressure medicines such as beta-blockers, water tablets (diuretics) and some antidepressants [1]. Tell a pharmacist or doctor what else you take, including over-the-counter and herbal products, before using it [1].

Suspected side effects from a salbutamol inhaler can be reported to the MHRA through the Yellow Card scheme, which helps monitor medicine safety in the UK [2]. Seek medical help for any serious reaction as well as reporting it.
