I Have Bronchial Asthma. I Normally Take One Tablet Of

I have bronchial asthma. I normally take one tablet of Montair 10 mg daily at bedtime. But today I mistakenly took it in the morning instead of having it at bedtime. Do I need to take it again today at bedtime? or should I take it tomorrow at bedtime as I usually do? Will there be any problem at night since I had the tablet in the morning instead of bedtime? Many thanks.regards. Ali Kasmani
