What is guanfacine HCl ER?
Guanfacine HCl ER is an extended-release form of guanfacine, a medicine that acts on alpha-2 adrenergic receptors. “ER” means the drug is designed to release slowly over time rather than all at once.
What is it used for?
Guanfacine HCl ER is commonly used to treat attention-deficit/hyperactivity disorder (ADHD). It helps improve symptoms like attention and impulsivity.
How does extended-release guanfacine differ from immediate-release guanfacine?
With extended-release (ER), the medication is released gradually during the day, which usually supports smoother symptom control and may reduce peaks and troughs compared with immediate-release guanfacine. Immediate-release forms are taken more frequently because they don’t last as long.
How is it taken and what to watch for
Because it is extended-release, guanfacine HCl ER is typically taken once daily (the exact schedule depends on the specific product and prescriber instructions). Patients should follow dosing directions closely and avoid changing the regimen without clinician guidance.
Common issues people watch for with guanfacine products include low blood pressure, dizziness, fatigue, and sleepiness—especially when starting treatment or adjusting the dose.
