Why does my doctor want me to take all 3 30 mg tablets all at once in the am?

thanks for your response....I got no reasonable response as to why I should take 90 mg all at once in the am....I am concerned about taking that much all at once. I am going to talk to my RPH in the morning.

thanks for your comment. That's how it was originally prescribed. 30 mg TID. But now the MD wants me to take them all at once in the am...this makes no sense to me....The total dose is still 90 daily? My fear is the drowsiness and possible fainting..

I was on 60 mg split up into two doses....The MD increased it to 90 three times a day and then I began to have high Systolic readings and the MD requested that I not split the doses up and to take all three in the am? This makes no sense to me since it is a XL med and the total daily dose adds up to 90 taken either way? I am concerned about taking all three at once....thanks for your response.
