IR lasts about 4-6 hours and x r lasts 12 hours. So if you take 20 mg of the immediate release twice a day you take 20 mg of the extended release once a day. They are the same dose.

I feel better already! Thank you.

Thank you to the Physician who answered my question today. The answer was far more informative than what I got from the Physicians I saw in person for my problem.

You have been more help than you know. I seriously don't know what my sisters situation would be today if you had not gone above and beyond just answering my questions.
