Before Using This Medicine
In deciding to use a medicine,
the risks of taking the medicine must be weighed against the good it will

allergic reaction to terazosin, prazosin, or doxazosin. Also tell your health
care professional if you are allergic to any other substances, such as foods,
preservatives, or dyes.

change the dose, or other precautions may be necessary. Tell your health care
professional if you are taking any other prescription or nonprescription (over-the-counter
