What is Guanfacine (Intuniv)?

Dosage of Guanfacine (Intuniv)

Guanfacine is an oral medication that treats ADHD and tic disorders. It is an extended-release tablet that can be taken once daily or as needed for symptom relief. The release of the medication is controlled and slow so that it can be effective for 12 hours.

It works by changing the effects of certain neurotransmitters in the brain called catecholamines, specifically dopamine and norepinephrine. These two chemicals help with thinking, focus, moods, and behavior control. People who have ADHD or tic disorders have problems with how these neurotransmitters work, so guanfacine helps to regulate them.

How does Guanfacine work?

Guanfacine is a selective alpha-two agonist. It works by regulating the levels of norepinephrine in the brain. This helps to improve focus and attention span, as well as reduce impulsivity and hyperactivity. It can also work to improve behavior control.

For people with ADHD, guanfacine helps to increase attention span and reduce hyperactivity. It also helps to improve impulse control. For people with tic disorders, it can help to decrease the number and severity of tics.

Dosage of Guanfacine (Intuniv)

The dosage of guanfacine that is prescribed will vary depending on the person’s age, weight, and condition being treated. It can be taken once daily or as needed for symptom relief.

For ADHD, the recommended starting dose is 0.25 mg to 0.50 mg per day, given in two divided doses. The maximum dose for this condition is 0.90 mg per day, given in two divided doses.

For Tourette syndrome, the recommended dose of guanfacine is typically a starting dose of 0.01mg/kg to 0.04mg/kg every morning and it can be increased up to a maximum single daily dose of 0.08mg/kg.

Directions Of Use

Guanfacine is usually taken once daily, in the morning or evening. You should swallow it whole with a full glass of water to avoid irritation in the throat. The tablets must not be broken or crushed because this can cause too much medicine at one time that may increase side effects and could be fatal. If you are taking guanfacine as needed for symptom relief, you should only take one tablet.

If you miss a dose of guanfacine, take it as soon as possible. However, if it is almost time for your next dose, skip the missed dose and continue with your regular schedule. Do not take two doses at once.
