You’ll usually take 1 - 2 puffs from a 100mcg Ventolin Evohaler when you need to relieve your asthma or COPD symptoms.
You may also take 2 puffs a short while before exercising to help prevent your symptoms.
Some people use their inhaler for regular treatment, and in this case, you’ll take 2 puffs up to 4 times a day.
Of course, these are only guidelines and you should always follow the instructions given to you by your doctor or healthcare team.
No matter how you personally use your inhaler, you should never take more than 8 puffs in 24 hours.
