TENEX Uses, Side Effects, Interactions, Warnings & Dosing
What is TENEX?
TENEX is the brand name for guanfacine and is available as an oral tablet.

What is TENEX used for?
TENEX is an alpha-2 adrenergic receptor agonist and is used to treat high blood pressure in people ages 12 years and older.
How does TENEX work?
TENEX is an alpha-2 agonist. It works by binding (attaching) to alpha-2 receptors in the brain. This lowers the amount of norepinephrine, a chemical that normally raises your blood pressure by squeezing your blood vessels.
How do I take TENEX?
TENEX is typically dosed as 1 mg by mouth once a day at bedtime. If needed, your provider might raise your dose after 3 to 4 weeks. The maximum recommended dose is 2 mg once day.
Is it safe for me to take TENEX?
TENEX is a safe and effective treatment when used for FDA licensed indications. However, like all medications, they may give you unwanted side effects. You should always discuss potential side effects with your physician to ensure the medication is suitable and right for you. You should not use this medication if you have hypersensitivity to TENEX, its inactive ingredients, or other products containing guanfacine.
