What special precautions should I follow?
Before taking doxazosin:
Always tell your doctor and pharmacist if you are allergic to doxazosin, prazosin (Minipress®), terazosin (Hytrin®), or any other medications.
Inform your doctor and pharmacist what prescription and non-prescription medications, vitamins, nutritional supplements, and herbal products you are taking. Be sure to mention if you are taking other medications for high blood pressure, as your doctor may need to change the doses of your medications or monitor you carefully for side effects.
Tell your doctor if you have or have ever had liver disease.
Moreover, please inform your doctor if you are pregnant, plan to become pregnant, or are breast-feeding. If you become pregnant while taking doxazosin, call your doctor.
Also, if you are having surgery, including dental surgery, tell the doctor or dentist that you are taking doxazosin.
You should know that doxazosin may make you drowsy or dizzy. Do not drive a car or operate machinery for 24 hours after the first time you take doxazosin or after your dose is increased.
Additionally, doxazosin may cause dizziness, lightheadedness, and fainting when you get up too quickly from a lying position. This is more common when you first start taking doxazosin and when your dose is increased. To avoid this problem, get out of bed slowly, resting your feet on the floor for a few minutes before standing up. If you experience these symptoms, sit or lie down.
