Side Effects Of Salbutamol Inhalers

Salbutamol is a safe and very effective medicine if you use it properly. It has very few side effects.

Common side effects of salbutamol

More than 1 in 100 people have these side effects after taking 1 or 2 puffs of their salbutamol inhaler. There are things you can do to help cope with them:

These side effects should gradually improve as your body gets used to salbutamol. Speak to a doctor if the advice on how to cope does not help and a side effect still bothers you or does not go away.

Serious side effects

It happens rarely, but some people may have serious side effects when taking salbutamol.

Call a doctor or call 111 straight away if you get:

• muscle pain or weakness, muscle cramps, or an irregular or more noticeable heartbeat - this can be a sign of low potassium levels
• a fast, irregular heartbeat that does not get better
• very bad dizziness, or feeling lightheaded

Call 999 or go to A&E now if:

Serious allergic reaction

It happens rarely but it's possible to have a serious allergic reaction (anaphylaxis) to salbutamol.

Call 999 now if:

• your lips, mouth, throat or tongue suddenly become swollen
• you're breathing very fast or struggling to breathe (you may become very wheezy or feel like you're choking or gasping for air)
• your throat feels tight or you're struggling to swallow
• your skin, tongue or lips turn blue, grey or pale (if you have black or brown skin, this may be easier to see on the palms of your hands or soles of your feet)
• you suddenly become very confused, drowsy or dizzy
• someone faints and cannot be woken up
• a child is limp, floppy or not responding like they normally do (their head may fall to the side, backwards or forwards, or they may find it difficult to lift their head or focus on your face)

You or the person who's unwell may also have a rash that's swollen, raised, itchy, blistered or peeling.

These can be signs of a serious allergic reaction and may need immediate treatment in hospital.
