Guanfacine ER (extended-release) is a prescription medication commonly used to treat Attention Deficit Hyperactivity Disorder (ADHD). It works by improving attention, reducing impulsivity, and supporting better emotional regulation. With the rise of telehealth services, patients can now access a Guanfacine ER online prescription after a virtual consultation with a licensed healthcare provider.
