How often should I use my inhaler
The medication in most asthma inhalers (like Ventolin and Salbutamol) lasts for between four and six hours. So it is safe to use your inhaler four to six times a day.
If you have an asthma attack though, it is safe to use this medication a lot more regularly.
If you have an asthma attack at home, you can use your inhaler every 30 to 60 minutes for 2 to 3 hours and it is unlikely to cause you any harm - unless you know you have a serious heart condition. That said, you should only use your inhaler this frequently during an asthma attack. If you overuse it, you risk relieving the symptoms of your asthma, but making your condition worse.
If you find yourself needing to use your inhaler every day, several times a day, it might be the case that there is a different type of medication that would work better for you. Speak to a doctor if you are unsure or concerned about how to use your inhaler safely or if you want to discuss other treatment options.
