High blood pressure facts
- High blood pressure (hypertension) is designated as either essential (primary) hypertension or secondary hypertension and is defined as a consistently elevated blood pressure exceeding 140/90 mm Hg.
- High blood pressure is called "the silent killer" because it often causes no symptoms for many years, even decades, until it finally damages certain critical organs.
- Poorly controlled high blood pressure ultimately can cause damage to blood vessels in the eye, thickening of the heart muscle and heart attacks, hardening of the arteries (arteriosclerosis), kidney failure, and strokes.

Guanfacine Hydrochloride Drug Center
Medical Editor: John P. Cunha, DO, FACOEP
Guanfacine hydrochloride (Brand Name: Tenex) is used to treat high blood pressure (hyptertension). It is a centrally acting antihypertensive with a2-adrenoceptor agonist properties. This medication is available in generic form. Common side effects include dry mouth, sedation, weakness, dizziness, constipation, and impotence.
The recommended initial dose of guanfacine hydrochloride when given alone or in combination with another antihypertensive drug is 1 mg daily at bedtime to minimize drowsiness. A doctor may increase dosage until the desired result is obtained. Guanfacine hydrochloride may interact with valproic acid, drugs affecting liver enzymes that remove guanfacine from your body (e.g., azole antifungals, rifamycins), products that cause drowsiness, including alcohol, antihistamines, drugs for sleep or anxiety, muscle relaxants, narcotics, cough-and-cold products, diet aids, or non-steroidal anti-inflammatory drugs (NSAIDs). Guanfacine hydrochloride should be used during pregnancy only if prescribed. It is not known if this medication passes into breast milk. Consult your doctor before breast-feeding. Stopping guanfacine hydrochloride suddenly could cause severe high blood pressure, anxiety, and other side effects.
