What is guanfacine, and what is it used for?
Guanfacine is a prescription medication that affects how the brain regulates nerve signals. It is most commonly used to treat attention-related symptoms in people with ADHD (attention-deficit/hyperactivity disorder) and may also be used for high blood pressure in some formulations/brands.
How does guanfacine work?
Guanfacine acts on specific brain receptors (alpha-2A adrenergic receptors). This can reduce certain overactivity signals in the nervous system, which helps improve attention, impulse control, and hyperactivity in ADHD.
What forms does guanfacine come in?
Guanfacine is available in different formulations, including versions designed to last longer through the day (often used for ADHD). The exact dosing schedule and effects depend on the specific product.
What side effects are common?
Common side effects can include sleepiness or tiredness, dizziness, low blood pressure, dry mouth, and constipation. Because it can lower blood pressure, some people feel lightheaded when standing up.
What should I watch for with guanfacine?
People taking guanfacine are usually advised to monitor for symptoms of low blood pressure (like dizziness or fainting), especially when starting treatment or changing the dose. It’s also important not to stop it abruptly without clinician guidance, since changes in dosing can affect blood pressure and other effects.
Is guanfacine the same as clonidine?
No. Both are related medications that can affect the same general pathways in the nervous system, but they are different drugs with different dosing schedules and side-effect profiles. They are not interchangeable without a prescriber’s direction.
