The usual dose of Ventolin is 2 inhalations every 4 to 6 hours. To prevent exercise-induced bronchospasm, use 2 inhalations 15 to 30 minutes before exercise. The effects of Albuterol last about 4 to 6 hours.
What should I do if I miss a dose of Ventolin?
Take the missed dose as soon as you remember. If it is almost time for your next scheduled dose, skip the missed dose. Do not use extra medicine to make up the missed dose.
What should I do if I take too much Ventolin?

How to prime a Ventolin Inhaler
If this is the first time you are using this inhaler, or if you haven’t used your inhaler recently, you should prime your inhaler. You do this by:
- Removing the mouthpiece cap
- Shaking the inhaler well
- Spraying once into the air, away from your face
- Then repeat steps 1-3 another three times, before using your inhaler as normal.
How to use a Ventolin Inhaler
You should follow the directions in the patient information leaflet that will accompany your inhaler. However, the following instructions also outline how to use your inhaler:
- Remove the cap from the mouthpiece and vigorously shake your inhaler
- Position the inhaler with the mouthpiece at the bottom and a finger on top of the canister (the canister should be at the top)
- Breathe out as much as possible, then immediately put the mouthpiece in your mouth and create a seal round it with your lips.
- Push down the top of the canister as far as possible, while breathing in slowly through your mouth
- After the spray has come out, you can take your finger off the canister and take the inhaler out of your mouth, but try to keep your mouth closed and hold your breath for at least 10 seconds if possible
- Breathe out completely and as slowly as you can for as long as possible.
- Replace the cap on the mouthpiece
- If you have been instructed to use more than one spray when you use your inhaler, wait 1 minute, then repeat steps 3-7.
Tips for your Ventolin inhaler
- Before using your Ventolin inhaler, you should check that the canister fits firmly inside the actuator (the plastic part of the inhaler).
- When not using your inhaler, always store it with the mouthpiece facing downwards and keep the cap on the mouthpiece.
- To prevent the build-up of bacteria or fungi, which can cause oral infections (oral thrush), you should clean the plastic part of your inhaler once a week (see instructions below).
How to clean your Ventolin Inhaler
You should try to clean your inhaler every week, following these instructions:
- Remove the canister from the plastic part of the inhaler (the actuator).
- Hold the actuator under warm water as it runs from the faucet. You should hold it here for at least 30 seconds.
- Then make sure you run the warm water through the mouthpiece for at least 30 seconds.
- Check inside to make sure there isn’t any build up of medicine or dirt inside the actuator. If there is, you may need to rinse it again until there’s no visible residue left.
- When clean, shake off as much excess water as possible and leave it to air-dry overnight if possible.
- When it is completely dry, you can replace the canister inside the plastic part. You should shake it thoroughly and spray it once, into the air, away from your face.
Failure to keep your inhaler clean could allow bacteria or fungi to build up inside the device, this increases your risk of infections such as oral thrush (yeast infection).
