I am a 68-year old man with Parkinson's disease and a history of low blood pressure. My urologist has put me on Doxazosin for bladder control, which lowers blood pressure. I have recently experienced a numbing in my right hand while I sleep. I tried wearing wrist protectors, but I still get numbing. My wife tells me she recently read that Doxazosin should not be used by PD patients because it can interfere with the most common medication used -- Stalevo, or Carbodopa/Levadopa. Can you confirm this?

There is a moderate drug interaction between the levodopa and doxazosin. The hypotensive effects (lowering of blood pressure) of each medicine may be intensified especially during the first few weeks of therapy. Dose adjustments of the antihypertensive (doxazosin) agent may be required. Patients should be advised to notify their physician if they experience dizziness or fainting.
You should talk to your doctor about the numbing of your hand.
