What is Ventolin?

A Ventolin inhaler is the most common type of inhaler given to asthma sufferers. It is a reliever inhaler which eases the symptoms of asthma. These include coughing, wheezing, a tightness in the chest and breathlessness.

What is Ventolin for?

Ventolin helps you to manage your asthma. It prevents an asthma attack from happening and eases symptoms as they occur after coming into contact with a trigger. It’s a short term rescue remedy to soothe irritated airways and allow you to breathe with greater ease.

How does it work?

There are a number of factors which can trigger asthma symptoms. Some common triggers include dust, respiratory infections, smoking, pet hair, pollen, allergies and cold weather. If you have asthma, coming into contact with your trigger/s irritates your airways which mean they are tighter than usual and it feels harder to breathe. The inhaler works by opening up the airways, relaxing the surrounding muscles to let air move in and out of the lungs more freely.

Is Ventolin a cure?

There is no cure for asthma. It’s a long-term condition but with the right treatment, it can be kept in check so that you can lead a normal and fulfilling life. Ventolin helps you to manage your asthma and can prevent an asthma attack from occurring.

How long does Ventolin take to work?

Ventolin is a quick relief medicine that will take effect right away. You should feel your symptoms ease off after a few minutes.

Is long-term use of Ventolin safe?

Ventolin is designed for short term relief of asthma symptoms. It’s safe to use in the long term as long as you’re not using it more than twice a week. Otherwise, you need to see your doctor who will prescribe you with a preventer inhaler. This is designed to be used every day to prevent symptoms from occurring and will reduce the need for your Ventolin inhaler. 

What are reliever inhalers?

A reliever inhaler is used for immediate relief when asthma symptoms- wheezing, coughing, breathlessness and chest tightness develop. 

How to look after your inhaler

When you’re not using your inhaler, you should always keep the cap on to prevent any dirt or small objects from getting lodged inside it. This could prove dangerous for your health if you were to breathe them in. Also ensure your inhaler is kept at a reasonable temperature, not too hot or cold. You should clean your inhaler as instructed once a week to prevent a buildup of medicine and keep it in good working condition.

Will Ventolin prevent an asthma attack?

Ventolin will help to manage symptoms as they occur. An asthma attack is characterised by being too breathless to speak, eat or sleep, your breathing coming faster and other symptoms getting worse. If this happens then take up to ten puffs of your Ventolin inhaler, leaving 30-60 seconds between each one. If you don’t feel better after this, then call 999 for an ambulance right away or if you feel worried at any point. Don’t feel afraid to seek emergency help.

How many puffs does each Ventolin Evohaler contain?

Each inhaler canister contains 200 puffs of Ventolin.


Active ingredients

The active ingredient is Salbutamol Sulphate, a fast acting bronchodilator, which helps the airways in the lungs stay open to make it easier for air to move in and out.

Inactive ingredients

Norflurane is the inactive ingredient which is used as the propellant in the inhaler to release the medicine.


What is the recommended dose of Ventolin?

The recommended dose for adults and adolescents over 12:
To relieve asthma – one or two puffs
To prevent asthma – two puffs 10-15 minutes before exposure to trigger
For regular treatment – two puffs up to 4 times a day (maximum dose is 8 puffs in a 24 hour period)

The recommended dose for children under 12:
To relieve asthma – one puff (two if required)
To prevent asthma – one puff 10-15 minutes before exposure to a trigger (two if required)
For regular treatment – two puffs up to 4 times a day (maximum dose is 8 puffs in a 24 hour period)

How to use a Ventolin inhaler

Before using it for the first time, test your inhaler by taking the cap off, shaking the canister and pressing down on the button to release a puff into the air with the mouthpiece pointing away from you. When you’re ready, repeat the shaking action and sit or stand with your back straight and chin slightly tilted upwards. Seal your lips around the mouthpiece of the inhaler and start to breathe in. As you do so, press down once on the canister and keep breathing in until your lungs are full. Hold your breath for ten seconds before gently breathing out. If you need to take a second puff, wait 30 seconds before repeating the steps and then replacing the cap.

Do I need to use Ventolin regularly?

You should use your Ventolin inhaler anytime you feel your symptoms flare up: if you are coughing, wheezing, feeling breathless or have a tight feeling in your chest. If you find you are using Ventolin three times a week or more, then report this to your doctor as you may need to have an additional inhaler prescribed to prevent symptoms from occurring.

Do I need to keep a Ventolin diary?

It’s useful to keep a diary to record how often you take your Ventolin medicine. You should include where and when you take it and any other factors you think are important. This can help you to identity triggers and allow your doctor to get an accurate picture of how well managed your asthma is. 

How to deal with someone having an asthma attack

If someone is having an asthma attack try to remain calm to avoid causing them any further panic. Locate their inhaler and help them to use it. If the asthma attack does not ease within a couple of minutes or if the person doesn’t have their inhaler then call 999 right away and stay with them until assistance arrives.

How to help someone use their asthma inhaler

To help someone use their asthma inhaler, you should consult their individual treatment plan which will have the details of which types of inhaler they need and what dose to take. Get them to sit up straight in a comfortable position. Take the cap off the inhaler, shake it and place the mouthpiece between their lips, guiding them to seal their lips around it. They need to breathe in at the same time you press down on the canister, holding their breath for up to ten seconds afterwards before releasing it slowly. If they are very breathless, their inhaler isn’t helping and you are unsure what to do then call for emergency help right away.

Can Ventolin cause thrush?

Ventolin does not cause oral thrush, however if you do not clean your inhaler regularly, you can allow the candida albicans fungus (the cause of thrush) to grow on the surface of the inhaler. Then when you use your inhaler, you also expose yourself to the fungus that causes thrush. Therefore, it is recommended that you wash the plastic part of your inhaler after each use to avoid oral thrush. 

Ventolin and pregnancy/breastfeeding

Ventolin is completely safe to use during your pregnancy and while breastfeeding. You should continue to take your asthma medication as usual and report any changes to your symptoms to your doctor.

Treatment Options

Do you really need Ventolin for asthma?

Everybody with asthma needs to have a reliever inhaler. Ventolin is just one brand. Whichever your preferred reliever inhaler, you absolutely need it to relieve symptoms in case you have an asthma attack. 

Ventolin vs Salamol

Ventolin and Salamol are different brands of the same medicine- Salbutamol. Some users find that the Salamol inhaler is smaller and there is a difference in taste but otherwise there is little difference between the two. Both brands will treat your asthma in the same way.

Ventolin vs Steroid Inhalers

Only preventer inhalers contain steroids. These are the inhalers that you should use everyday to prevent asthma symptoms from occurring. People with mild asthma usually don’t need this type of treatment. Your Ventolin inhaler should be taken for immediate relief when you experience symptoms or an acute attack. 

Ventolin vs combination inhalers

A combination inhaler may be prescribed if using both a preventer and reliever (Ventolin) inhaler is not keeping your asthma under control. A combination inhaler holds preventer medicine to stop your airways from becoming inflamed while also providing ongoing relief from asthma symptoms. This should be taken regularly as prescribed but you’ll still need your Ventolin inhaler if an attack comes on.

What is a spacer?

A spacer is a device shaped like a plastic tube that you can attach to an asthma inhaler to help you use it. This is for anyone who struggles to use their asthma inhaler, children in particular. Once attached, you push down on the canister of the inhaler to release the medicine into the spacer before you breathe it in. 

Ventolin alternatives

There are complementary therapies which can help to manage your asthma. There is research to suggest that breathing techniques such as the Buteyko method can improve your symptoms but this should not be used in place of your inhaler when you need it. You should always have your Ventolin inhaler to hand in case you have an asthma attack.

What is Ventolin HFA?

Ventolin HFA is a branded medicine used to treat asthma which is administered through an inhaler. It’s a form of Salbutamol and the inhaler is blue in appearance. 

Are Ventolin and Salbutamol the Same?

Ventolin and Salbutamol are basically the same thing. Salbutamol is the name given to the  medicine itself while Ventolin is a brand of Salbutamol. You may be prescribed either one but their chemical make-up is the same. 


Can I buy Ventolin over the counter?

Ventolin is only available on prescription so you cannot buy it over the counter. If you have an asthma diagnosis and have used a Ventolin inhaler in the past, then you may be eligible to order one online with Dr Felix. Simply fill out our online consultation so one of our doctors can assess it.

Can I take Ventolin on a plane?

You can take your Ventolin inhaler on a plane provided you follow airport regulations. You’ll need to place your inhaler in a sealed plastic bag, as you would with any other liquids under 100ml. It’s best to keep your inhaler inside your hand luggage in case your checked in baggage is delayed or goes missing. This also means that you have your inhaler to hand in case you need it. You should also take a copy of your prescription or a letter from your doctor to confirm which medicines you are taking in case this gets checked at customs.

What does Ventolin taste like?

If the medicine hits the back of your throat instead of going straight into your lungs then you may be able to taste it. Some users report that Ventolin has a bitter taste.

Can you recycle Ventolin inhalers?

Asthma inhalers cannot be recycled along with your household recycling that is operated by the council. A scheme called Complete the Cycle allows you to recycle your old inhalers by taking them to a participating pharmacy in the UK. 

Will Ventolin help other chest or throat symptoms?

Ventolin opens up the airways by relaxing the muscles around them to allow air to move in and out of the lungs with greater ease. If you have a feeling of tightness in the chest, coughing or wheezing as a result of asthma, Ventolin will help. It cannot treat the symptoms of a cold or chest infection. If you experience additional symptoms or need to use your Ventolin inhaler more than twice a week, see your GP for advice.

Is Ventolin a steroid?

Ventolin is not a steroid. Quick relief asthma inhalers such as Ventolin do not contain steroids, only preventer inhalers do.

Does Ventolin become less effective over time?

If you are frequently using your Ventolin inhaler too often then it may not be as effective. If you use it three times a week or more, then you should see your doctor for a review as it’s likely you need a preventer inhaler. If your asthma is managed correctly then your Ventolin inhaler will remain effective. If your inhaler has passed the expiration date then it may not work as well and should be discarded. 

What causes asthma?

There is no definite cause but research indicates that you are more likely to have asthma if it runs in the family or you have allergies, a history of bronchitis as a child or were born prematurely. You are also more at risk if you smoke or your mother smoked during pregnancy. 

What triggers asthma?

Common asthma triggers include allergies, hay fever, dust, pet hair, tobacco smoke, cold weather, flu and chest infections and pollution.
