i have been taking 1/2 mg of Pramipexole. prescribed dosage is 1mg but too strong and makes me sick to my stomach. I pick up a prescription this afternoon and about 20 minutes ago found that they are different in color and has 9/4 on them. I looked them up and found they are extended release tabs. I'm afraid to take them because of the strength and afraid to split them because of the extended release factor. Will they work if I do split them? By the way, I would appreciate a quick response if possible because I have too take it soon. Thank you Janet.
