Salbutamol (inhaler)

Salbutamol is a short-acting bronchodilator — often called a “reliever” inhaler. It is commonly prescribed for asthma and sometimes for COPD to relieve wheeze, cough, or breathlessness when needed.

Your GP or asthma nurse may also prescribe a preventer inhaler for regular use if appropriate.

Salbutamol relaxes muscles around the airways, helping them open so breathing can improve. Effects often begin within minutes but do not treat underlying airway inflammation on their own.

Preventer medicines reduce inflammation; relievers treat sudden symptoms.

Use your inhaler as demonstrated by your nurse or pharmacist. Technique (spacer use, shaking the device, timing of breath) affects how much medicine reaches your lungs.

If you need your reliever more often than usual, contact your GP or asthma nurse — it may mean your asthma needs review.

Common effects can include tremor, feeling your heart race, headache, or mild cough after inhaling.

These are often mild. If they are severe or worrying, seek advice from your pharmacist or GP.

Get urgent help if reliever use does not ease breathlessness, if you cannot speak in full sentences, or if lips or nails look blue — these can be signs of a severe attack.

Severe allergic reactions to salbutamol are uncommon but require emergency care.

Salbutamol is usually used as needed rather than on a fixed schedule. If you use a regular schedule for exercise-induced symptoms, take the next dose as planned if you miss one — your prescriber can clarify.

Do not exceed the maximum doses advised in your action plan or leaflet without medical advice.

Your prescriber considers heart rhythm problems, pregnancy, and allergies. Salbutamol is widely used when clinically appropriate.

Always tell your GP about all medicines you take, including other inhalers.

Some beta-blockers can oppose the effects of salbutamol; your prescriber manages this if both types of medicine are needed.

Other interactions are possible; your pharmacist can check when new medicines are started.

Salbutamol is often used in pregnancy when asthma needs treatment; poorly controlled asthma can be harmful to mother and baby.

Your GP or midwife can discuss the balance of benefits and any alternatives.

Asthma reviews may include peak flow, symptom scores, and inhaler technique checks.

You may receive a written asthma action plan describing when to adjust treatment or seek help.

Other relievers (such as terbutaline) or additional controllers may be considered. For COPD, treatment plans differ from asthma and should be led by your clinician.

Your GP or respiratory nurse selects options based on diagnosis and severity.
