What is the ruling on the fasting of an asthma patient who uses an inhaler during fasting?

Question:
He says: I suffer from asthma, and I use the inhaler during the day of fasting. It contains powder, and I sometimes taste it. Is there anything required of me? Is my fast valid?

Answer:
Do not take it except out of dire necessity. When it is a dire necessity, take it and make up that day, because you are sick. It is permissible for the sick person to break his fast and take medication and make up the day, unless he is able to postpone the treatment or the inhaler until night. If he can, he postpones it. But if he is unable to, he takes it and is considered to have broken his fast due to illness, so he makes up that day. Yes.
