Stand or sit upright when using your inhaler. Remove the mouthpiece cover and check inside to ensure it's clean. Shake the inhaler 4-5 times.
Hold the inhaler upright with your thumb on the base and fingers on the top of the canister – your hand should make a C shape. Breathe out as far as is comfortable and place the mouthpiece in your mouth, between your teeth. Close your lips around it and don't bite.
Breathe in through your mouth – just after you start to breathe in, press down on the top of the canister to release a puff of medicine. Continue breathing in steadily and deeply. Hold your breath for as long as is comfortable.
Wait 30 seconds and repeat to take another puff. Replace the mouthpiece cover after use.
