I am on 400/12 twice daily and I just took an extra puff without thinking, instead of my salbutamol, which I meant to take because my chest was tight.
I just wondered whether I should do anything about it. I only took one puff absent mindedly.
I took my usual dose at around 8am.
I've done this a few times, usually when I can't remember if I twisted it or not!
I've never done anything about it, it's only one puff. I've never asked about it though so if you're concerned maybe give the helpline a ring?
I can't imagine it being an issue though.
I wouldn't worry about the odd extra puff occasionally. It might make you a little shakey and heart rate higher, but not for long.
Thanks! I rang 111 and they said the same. Didn't notice any difference apart from maybe I could breathe a bit better! Thanks for the reassurance 
Don't worry it won't cause any long term issues! I used to be on 400/12 2 puffs twice a day with the option to take upto an extra 12 (was on tbf SMART regime though it's unlicensed) not on it any more though!
Huff and puff sort of a day
