Low doses of Deprenyl (2mg) and or cabergoline, even if taken separately months apart both cause extreme constant dizziness that just makes me want to lie down until the drug is out of my body. My blood pressure remains normal while this happens. I do not understand it for the life of me. Can anyone explain the mechanism of this? I also start feeling somewhat tired... it is a feeling of say you stayed up 2 days straight and just want to lie down and pass out. If anyone has any advice into why these dopaminergics would be causing this please let me know. Thanks.
