What is a guanfacine 1 mg tablet used for?
A guanfacine 1 mg tablet is a small-dose form of guanfacine, a medicine used to help treat high blood pressure (in the “extended-release” forms) and, in some products, attention-deficit/hyperactivity disorder (ADHD) (commonly with specific extended-release guanfacine products). The exact approved use depends on the specific brand/formulation you have (immediate-release vs extended-release).
How should guanfacine 1 mg tablets be taken?
How you take a guanfacine 1 mg tablet depends on whether it is extended-release or immediate-release:
- Extended-release: usually taken once daily, and the tablet must be swallowed whole (not crushed or split unless the product instructions allow it).
- Immediate-release: taken more often (commonly 2–3 times daily), depending on the prescription instructions.
If you tell me the brand name on your bottle (for example, the exact product name), I can narrow down the typical dosing schedule more accurately.
What are common side effects people notice?
Common guanfacine side effects can include:
- drowsiness or fatigue
- dizziness or lightheadedness
- low blood pressure
- dry mouth
- constipation
Because it can lower blood pressure, some people feel worse when standing up quickly.
What risks should patients watch for?
Key safety issues related to guanfacine include:
- Low blood pressure and slow heart rate, which can cause fainting or dizziness.
- Sedation, especially when starting or increasing the dose.
- Stopping suddenly may cause problems in blood pressure control for some users, so follow prescriber instructions for any dose changes.
If you have symptoms like fainting, severe dizziness, or very slow heart rate, you should seek medical advice promptly.
Is guanfacine 1 mg the same as extended-release guanfacine?
No. “Guanfacine 1 mg tablet” could refer to different formulations. The clinically important distinction is:
- Immediate-release vs extended-release, which affects dosing frequency and how the drug is released in the body.
What should you ask your pharmacist if you have guanfacine 1 mg?
To use the medication safely, confirm:
- the exact product name (brand)
- whether it is extended-release
- your prescribed dosing schedule
- what to do if you miss a dose
- whether you should avoid alcohol or be cautious with other medicines that can cause drowsiness or lower blood pressure

If you share the brand name (and whether it says ER/extended-release), plus what it was prescribed for (blood pressure or ADHD), I can tailor the dosing and side-effect guidance to the exact type you have.
