Hello, and thank you for posting on Healthcare Magic!
is a powerful blood pressure medicine. It works by causing your blood vessels to dilate (open up). If you were taking too much clonidine, you would feel tired and possibly dizzy when you stand up (this effect would be from blood pressure that was too low). Clonidine will not make your heart rate
slow down (in fact, the opposite would happen if it dropped your blood pressure too much).
I understand that the symptoms you are describing started around the time you started the clonidine. But I believe that something else is causing them. The symptoms you describe are very non-specific, meaning that they could be caused by multiple different medical problems. It is unlikely that they are related to a particular blood pressure medicine or to an interaction between medicines. You should make an appointment with your doctor to be evaluated for these new symptoms.
I hope I have given you some useful information, and wish you the best of health.
