Medication details


Ventolin Evohaler 100mcg is a medication used to treat respiratory conditions such as asthma and chronic obstructive pulmonary disease (COPD). It contains the active ingredient salbutamol, which works by relaxing the muscles in the airways to help improve breathing.  The medication is delivered through an inhaler device known as an Evohaler, which releases a measured dose of the medication as a fine mist to be inhaled into the lungs.


Using Ventolin Evohaler correctly is crucial for achieving optimal results. Here's a step-by-step guide on how to use the inhaler effectively:

Step 1: Check the Inhaler
Before using Ventolin Evohaler, ensure that the plastic case contains an embossed letter "V" to help you identify the inhaler.
Shake the inhaler well to ensure even distribution of the medicine.

Step 2: Prepare for Inhalation
Stand or sit upright and remove the mouthpiece cover.
Check both the inside and outside of the mouthpiece for cleanliness.

Step 3: Breathe Out
Breathe out gently to prepare for inhalation. Do not breathe in again yet.

Step 4: Inhale the Medicine
Place the mouthpiece between your teeth, making sure not to bite.
Start breathing in slowly through your mouth, and while doing so, press down on the top of the canister to release a puff of the medicine.
Continue to breathe in deeply and steadily.

Step 5: Hold Your Breath
Hold your breath for a few seconds after inhaling the medicine.
If your doctor has prescribed two puffs, wait for about half a minute before taking the second puff.

Step 6: Replace the Mouthpiece Cover
After use, immediately replace the mouthpiece cover to keep out dust.
Firmly push and click the cover into position.

Step 7: Clean Your Inhaler
To prevent blockages, clean your inhaler at least once a week.
Remove the metal canister from the plastic casing, rinse the casing under warm water, and dry it thoroughly. Do not immerse the metal canister in water.

Remember, proper technique is essential for effective asthma management. If you're unsure about using Ventolin Evohaler, consult your doctor, nurse, or pharmacist for guidance.


The active ingredient in Ventolin Evohaler is salbutamol sulfate, which belongs to a group of medicines known as fast-acting bronchodilators. These medications work by helping to keep your airways open, making it easier to breathe and alleviating symptoms such as chest tightness, wheezing, and coughing.

Before using Ventolin Evohaler, it's essential to be aware of certain warnings and precautions to ensure your safety and the effectiveness of the treatment:

1. Allergic Reactions:
If you experience signs of an allergic reaction, such as swelling of the face, lips, mouth, tongue, or throat; difficulty swallowing or breathing; itchy rash; faintness; or collapse, stop using Ventolin Evohaler immediately and seek medical attention.

Inform your doctor, nurse, or pharmacist if you have or have had any of the following conditions:
Active asthma with frequent symptoms, flare-ups, or limited physical ability
High blood pressure
Overactive thyroid gland
History of heart problems, irregular heartbeat, or angina
Taking xanthine derivatives or steroids for asthma
Taking water tablets (diuretics)

3. Other Medications:
Share all medications you are taking, including over-the-counter and herbal medications, with your healthcare provider. This is important to avoid potential interactions that could affect the effectiveness of Ventolin Evohaler.

4. Pregnancy, Breastfeeding, and Fertility:
If you are pregnant, breastfeeding, planning to have a baby, or suspect you may be pregnant, consult your healthcare provider before using Ventolin Evohaler.

5. Asthma Control Test: Assessing Your Asthma Control:
Regularly assess your asthma control using tools like the Asthma Control Test. This test can help you and your healthcare provider determine whether your asthma is well-controlled or needs adjustments to your treatment plan.

6. Storage and Disposal:
Store Ventolin Evohaler below 30°C, protecting it from frost and direct sunlight. Do not expose the inhaler to temperatures higher than 50°C, and never puncture, break, or burn the inhaler, even when it's empty. If the inhaler becomes very cold, warm the metal canister in your hands before use. To ensure proper disposal, ask your pharmacist for guidance on disposing of medicines you no longer use.
