Pramipexole
"Pramapexole can cause fainting.
I had been quite please with the affects of pramipexole during the 3 months I had been on it.  However, for about 3-4 weeks prior to my hospitalization, I just felt out of sorts.  I began to notice a feeling of being lightheaded.  One morning I bounded out of bed - standing up too quickly - and woke up a few moments later having fallen against a wall. I didn't too very much enjoy the resultant scrapes.  (Neither did the wall)
After a visit to the ER followed by two days of very impressive detective work, the very fine doctors informed me that Pramipexole - also known as Mirapex - was the culprit.  Take this drug seriously.  I works quite well but at a potential cost.  Hope this benefits you all."
