Ventolin Evohaler - 100mcg/200 Dose

What is the Ventolin Evohaler?

The Ventolin Evohaler is a fast-acting reliever inhaler used to treat symptoms of asthma and other airway conditions. It contains salbutamol, a bronchodilator that works quickly to open your airways, making it easier to breathe.

It is commonly used as a reliever inhaler, meaning it works quickly to ease symptoms such as wheezing, shortness of breath, and chest tightness.

Is an evohaler the same as an inhaler?

Yes, an evohaler is a type of inhaler.

Inhaler is a general term for devices that deliver medication into the lungs. An evohaler specifically refers to a pressurised inhaler that releases a fine mist when pressed.

Other types of inhalers include:

• dry powder inhalers (DPIs)
• soft mist inhalers

Each type works slightly differently, but all aim to deliver medication directly to the airways.

How does the Ventolin Evohaler work?

The Ventolin Evohaler is a pressurised metered-dose inhaler (pMDI) that delivers a measured dose of salbutamol directly into the lungs. Each inhaler contains 200 doses of 100 micrograms of salbutamol.

Salbutamol is a short-acting beta-2 agonist (SABA). It works by relaxing the muscles surrounding the airways, allowing them to widen.

This makes it easier for air to flow in and out of the lungs, relieving symptoms of bronchospasm.

How quickly does the Ventolin Evohaler work?

Ventolin works rapidly after inhalation.

• Onset of action: within a few minutes.
• Peak effect: within 30–60 minutes.
• Duration: around 4–6 hours.

The speed of the treatment means you can use it to relieve sudden asthma symptoms, while also preventing symptoms triggered by exercise.

How to use your Ventolin Evohaler

It’s worth familiarising yourself with the proper way to use your inhaler, to make sure the medication reaches your lungs effectively.

To use your Ventolin Evohaler:

• Remove the mouthpiece cover and shake the inhaler.
• Breathe out gently.
• Place the mouthpiece between your lips and seal tightly.
• Press the inhaler while breathing in slowly and deeply.
• Hold your breath for a few seconds before exhaling.

Your healthcare provider may recommend using a spacer device to improve delivery.

Ventolin Evohaler dosage

You should always follow the specific dosage prescribed by your clinician.

A typical dose of salbutamol is:

• Adults and children: 1–2 puffs as needed.
• Maximum use depends on the individual prescription.

If you find you need to use your inhaler more frequently, this may indicate that your condition is not as well-controlled as it could be.

How to clean your evohaler

To keep your inhaler working properly:

• remove the metal canister from the plastic casing
• rinse the plastic parts under warm water
• allow to air dry completely before reassembling

Cleaning your inhaler regularly helps prevent blockage and makes sure that your medication is delivered correctly.
