About Ventolin

Ventolin is the common blue reliever inhaler used for asthma. It contains the quick-acting active ingredient Salbutamol Sulphate that provides relief from symptoms of asthma. Ventolin Evohaler contains 100ug of Salbutamol in a device known as a pressurised metred dose inhaler or PMDI. Ventolin Accuhaler contains 200ug of Salbutamol in a disc-shaped device known as an Accuhaler. 

Ventolin may also be used to prevent asthma if you know you are about to be exposed to a trigger such as vigorous exercise. Ventolin will not prevent asthma for a long period of time, it is short-acting and primarily focused on relieving the symptoms of an asthma attack as fast as possible to restore normal breathing. Due to this, it is often used alongside a preventer inhaler (steroid inhaler) for those with frequent chronic asthma.

Asthma Overview

Asthma is a common condition that affects the body’s respiratory system. It is caused by inflammation in the lungs, and in particular, its smaller airways (know as bronchioles) and air sacs (known as alveoli). This results in constriction of the airways and a number of asthma symptoms such as:

  • Wheezing
  • Shortness of breath
  • Chest tightness
  • Coughing

There are currently 5.4 million people in the UK receiving asthma treatment, and it is a long-term, chronic condition. However, symptoms can worsen or improve over time, and the severity can often depend on a number of external factors known as triggers or allergens. Common triggers and allergens are pollen, dust, animal hair, weather events and pollutants.

How does Ventolin work?

Ventolin (salbutamol) works directly at the site of inflammation, the lungs. After being inhaled, it attaches directly to what’s known as a beta-receptor in the lungs. Attaching to this receptor causes the tightened smooth muscles around the airways (bronchioles) to relax, widening them. Relaxing the muscles in the airways relieves asthma and restores the ability to breathe normally.

As the medicine is deposited directly into the lungs, a measure of relief occurs very quickly with the full effect taking place over the next 5 to 30 minutes. The effect will generally last for between 4 to six hours.

Inhaler Comparison

Ventolin is available in two forms via our online doctor service. As an Evohaler, or as an Accuhaler. The Ventolin Evohaler is a 'press and breathe' inhaler (pMDI). This means that you need to press down on the inhaler to release the dose and breathe in as you do so. You can read our full guide on how to use different types of inhalers if you're unsure which type of inhaler you usually use.

The Accuhaler meanwhile, contains salbutamol as micro-powders, which are inhaled into the lungs. This type of inhaler is activated upon breathing, so you don't need to time your breath as you do with a normal inhaler. Accuhalers are often more suited to people who may struggle to use an aerosol inhaler due to a disability or other reasons.

Dosing and using Ventolin Inhalers

It is important that you speak to your doctor about an asthma action plan. This plan will contain information specific to the action and dosing you should follow in the case of an asthma attack as dosing may differ based on people and the severity of the asthma symptoms.
For adults and children over 12 using Ventolin Evohaler:

To relieve asthma - Inhale ONE or TWO puffs, when required as directed by nurse or GP. Use a maximum of eight puffs in a 24 hour period.

To prevent asthma - Inhale TWO puffs 10-15 minutes before exposure to a known trigger.

If you find you require your inhaler more often than this, speak to your GP.

Watch a video on how to use a pressurised metered-dose inhaler.

For adults and children over 12 using Ventolin Accuhaler:

Inhale ONE dose up to four times a day when required or as directed by your nurse or GP. Use a maximum dose of four inhalations in 24 hours.

Watch a video on how to use an Accuhaler.

Alternative Asthma Inhalers

There are various asthma inhaler devices and medicines that may suit your needs. These are split into reliever inhalers and preventer inhalers. If your asthma symptoms are not adequately controlled with just a reliever inhaler, talk to your doctor about a preventer inhaler. If you are having difficulty using any of your inhalers, talk to your doctor about changing to a different device that you may find easier to use or review your inhaler technique with a health professional.

Can I buy Ventolin over the counter?

No, Ventolin can not be bought over the counter, as it is a prescription-only medication. This means you need to have a doctor prescribe this. If you have not previously been diagnosed with asthma, it is important to make an appointment with your local GP, so they can safely diagnose your symptoms.

Can I buy Ventolin online?

Yes. If you have been previously diagnosed with asthma and prescribed Ventolin, you can use our online service, to get a repeat supply. The online supply of Ventolin is for a patient whose asthma is controlled. If you are finding your asthma is difficult to keep under control, you should continue to see your local doctor for your repeats.

What is the difference between Ventolin and Salamol / Salbulatmol inhalers?

Ventolin is the original branded version of Salbutamol, however both Ventolin and Salamol / Salbutamol inhalers contain the same active ingredient, Salbutamol.

How long does it take Ventolin to work?

After correct inhalation of a Ventolin inhaler, you should notice your asthma symptoms to improve straight away with the full effect within 5-25 minutes.

How many puffs of Ventolin is safe?

If used correctly, you should only use TWO puffs of Ventolin at once, or a maximum of EIGHT puffs over a 24 hour period (over 4 doses).

If you find you require your inhaler more frequently, speak to your doctor or pharmacist.

How do I use a Ventolin inhaler?

Depending on whether you have an Evohaler (press and breathe), or an Accuhaler (breathe in), the technique and advice for use of your inhaler are different. You can refer to your patient information leaflet, or read our guide on the different inhaler types.

How long should a Ventolin Inhaler last?

This depends on the severity of your asthma and how well it is controlled.

If your asthma is mild and well-controlled, your Ventolin inhaler should last a few months. Other asthma sufferers may find it will only last four or five weeks.

Is Ventolin a steroid inhaler?

No, Ventolin is a reliever inhaler containing salbutamol, a short-acting substance that opens the airways. Steroid inhalers are known as preventer inhalers and contain corticosteroids that prevent asthma symptoms over a long period of time.
