What should I watch for?

When you check your blood pressure, write down the measurements to show your doctor or health care professional. If you are taking this medicine for a long time, you must visit your health care professional for regular checks on your progress. Make sure you schedule appointments on a regular basis.
You must not get dehydrated. Ask your doctor or health care professional how much fluid you need to drink a day.
