alpha blockers -- used to treat an enlarged prostate gland or high blood pressure -- including tamsulosin (Flomax), alfuzosin (Uroxatral), doxazosin (Cardura), and terazosin (Cardura)
psychiatric medications, particularly amoxapine (Asendin), chlorpromazine (Thorazine), and thioridazine (Mellaril).
