Guanfacine (Systemic)
Brand Names : Tenex
CategoryDescriptionGuanfacine (GWAHN-fa-seen) belongs to the general
class of medicines called antihypertensives. It is used to treat high blood
pressure (hypertension).
High blood pressure adds to the workload of the heart and arteries. If
it continues for a long time, the heart and arteries may not function properly.
This can damage the blood vessels of the brain, heart, and kidneys, resulting
in a stroke, heart failure, or kidney failure. High blood pressure may also
increase the risk of heart attacks. These problems may be less likely to occur
if blood pressure is controlled.
Guanfacine works by controlling nerve impulses along certain nerve pathways.
As a result, it relaxes blood vessels so that blood passes through them more
easily. This helps to lower blood pressure.
Guanfacine is available only with your doctor's prescription, in the following
dosage form:
