What brand names does guanfacine come in?
Guanfacine is sold under multiple brand names depending on the product form (immediate-release vs. extended-release). In the U.S., the best-known brands are:
- Intuniv (extended-release)
- Tenex (immediate-release)
Is there a difference between Intuniv and Tenex?
Yes. Intuniv is formulated to release guanfacine over an extended period (once-daily dosing is typical), while Tenex is an immediate-release version with different dosing timing.
What conditions is guanfacine used for under each brand?
Commonly, guanfacine products are used in clinical practice for:
- ADHD (most notably the extended-release form, Intuniv)
- Sometimes hypertension or other off-label uses, depending on prescriber judgment and local labeling
(Exact approved indications can vary by country and by the specific formulation.)
Is there a generic version of guanfacine?
Generics are widely available for many guanfacine formulations, including extended-release products, depending on the market and the specific product strength and form.

Why do people search “guanfacine brand” online?
Searchers often want to confirm:
- Which brand they were prescribed (Intuniv vs. Tenex)
- Whether their brand has a generic alternative
- Whether dosing changes if they switch products (especially between extended-release and immediate-release forms)
How can switching between guanfacine brands or formulations affect dosing?
Because extended-release and immediate-release guanfacine release differently, switching between formulations can change how the dose is scheduled and how the medicine feels day to day. Patients generally should not switch formulations without their prescriber’s guidance.
Where can I verify the exact brand on my prescription?
The most reliable source is the prescription label and the pharmacy record, which will show the specific product name (for example, Intuniv or Tenex), strength, and formulation type.
If you tell me your country and strength, I can narrow it down
If you share the brand name you see (or the strength on the label) and your country, I can identify which guanfacine formulation that corresponds to and what it’s typically used for.
