Guanfacine (brand name Tenex) is a centrally acting antihypertensive agent. Guanfacine lowers both systolic and diastolic blood pressure by activating the central nervous system α-2 adrenergic receptors, which results in reduced sympathetic outflow leading to reduced vascular tone. Its adverse reactions include dry mouth, sedation, and constipation.
[edit] Uses
Guanfacine can be used to control high blood pressure. It works by reducing heart rate and relaxing blood vessels.
It is also sometimes prescribed as an off-label treatment for attention-deficit hyperactivity disorder.
[edit] Side effects
Usual: Dizziness, drowsiness, headache, constipation, gas pains, diarrhea, loss of appetite, fatigue, and nasal congestion may occur.
Rare: chest pain, shortness of breath, skin rash, swelling of the hands or feet, blurred vision, yellowing of the eyes or skin.
Others: mental/mood changes, tingling of the hands or feet, dry mouth, impotence, decreased sexual desire, vision changes, taste changes, ringing in the ears, leg cramps.
