What does “guanfacine” refer to as an ingredient?
Guanfacine is the active ingredient (the drug substance) used in medications for conditions such as high blood pressure and attention-related disorders, depending on the specific product. The “ingredient” name you’ll see on labels and prescriptions is usually just “guanfacine” plus a formulation qualifier such as immediate-release or extended-release.
What other ingredients are in guanfacine tablets or extended-release tablets?
Most guanfacine products contain:
- Guanfacine (the active ingredient)
- Inactive ingredients (excipients) such as binders, fillers, coatings, and other formulation components
The exact inactive ingredients vary by manufacturer and by whether the product is immediate-release or extended-release. If you tell me the brand name (for example, the exact product you have), I can help identify the likely ingredient set for that specific formulation.
Immediate-release vs extended-release: does the “ingredient” change?
The active ingredient is the same compound (guanfacine), but extended-release versions use a formulation designed to release the drug over time. That means the inactive ingredient composition and tablet coating structure can differ, even though “guanfacine” remains the ingredient you’re targeting.
Is guanfacine a salt (like guanfacine hydrochloride)?
Many guanfacine products are described using a salt form in labeling (commonly guanfacine hydrochloride), but some labels may list it simply as “guanfacine.” The presence of a salt form affects how it’s named on packaging, not the underlying active drug entity.
How to check the exact ingredient list for your specific guanfacine product
To get the precise list of all ingredients (including inactive ones), use:
- The “Inactive ingredients” section in the medication’s prescribing information or patient leaflet
- The package insert for the specific brand and strength
If you share the brand name and strength (and whether it’s immediate-release or extended-release), I can help you narrow down what’s typically in that exact product.
