What is Intuniv

Guanfacine

The Generic name of this drug

Treatment Summary

Guanfacine is a medication used to treat high blood pressure and attention deficit hyperactivity disorder (ADHD). It was first developed in 1974 and approved by the FDA in 1986. Guanfacine works by stimulating alpha-A2 adrenergic receptors, which helps regulate blood pressure and can improve focus and attention in ADHD patients.

Effectiveness

How Intuniv Affects Patients

Guanfacine helps manage ADHD by activating an alpha-2A adrenergic receptor. It only needs to be taken once a day and is usually considered safe, but it can cause low blood pressure, a slow heart rate, or fainting. Patients should be warned of these potential side effects.

How Intuniv works in the body

Guanfacine helps treat Attention Deficit Hyperactivity Disorder (ADHD) by targeting the sympathetic nervous system, which controls how your heart and circulatory system work. It does this by binding to alpha-2A receptors, which decreases the activity of the sympathetic nervous system.

Intuniv for Attention Deficit Disorder with Hyperactivity

My daughter has been on Intuniv for a few years. We started her on 2mg, and now she's up to 4mg. I'm not happy because she's gained about 25lbs in just 3 months. Her doctor says the meds can cause this on high doses, so we're looking for something new.

Intuniv for Attention Deficit Disorder with Hyperactivity

My daughter has been reaping the benefits of this medication for years now. At just 9 years old, she is able to focus much better in school thanks to the 3 mg dosage. Additionally, she doesn't have any trouble sleeping and takes the medicine first thing in the morning.

This medication has really helped me focus on my daily tasks. The only downside is that it makes me feel nauseous. I would still recommend it to others, though.

Intuniv for Attention Deficit Disorder with Hyperactivity

My son was taking this in conjunction with concerta. He became a very different person; low energy, depressed, mood swings, and feelings of worthlessness characterized his demeanor. There were also anger issues at school. We weaned him off of the Concerta, Prozac and Intuniv. He now takes a small dose of generic Ritalin. He's doing great now.

Intuniv for Attention Deficit Disorder with Hyperactivity

Almost immediately after taking this medication, my heart rate slowed down to a dangerous level. I felt weak and dizzy, and could barely move. I tried to keep taking it, but after the second dose, I was terrified my heart was going to stop. I called my doctor and stopped taking it.

Intuniv for Attention Deficit Disorder with Hyperactivity

I was prescribed this drug to take in addition to Lamictal 50mg and Vyvanse 50mg. I started taking this drug a few days before visiting my parents for Thanksgiving. I was overtaken by spells of obsessive thinking and was so tormented by vivid memories of childhood that I was unable to sleep. After I came off the drug, I got better within a few days. Not worth it for me.

Intuniv for Attention Deficit Disorder with Hyperactivity

My son's behavior changed dramatically for the worse after being put on this medication. He became angry, depressed, and had thoughts of self-harm. I am grateful that we are getting him off of this drug and hope that the effects are not permanent.

Intuniv for Attention Deficit Disorder with Hyperactivity

DO NOT TAKE THIS DRUG. I was absolutely horrified reading the reports of children taking this drug, and then I took it as a 20 year old and had an awful experience myself. I'm generally a very active person, but after taking this medication I was unable to even get out of bed without passing out. Additionally, it gave me chest pains and really sapped my energy and personality.

Organizational Skills Training vs Mindfulness for ADHD

13 - 17
All Sexes
Seattle, WA

This randomized control trial comparing Organizational Skills Training (OST) and Mindfulness-Based Intervention (MBI) among adolescents with a pre-existing ADHD diagnosis presenting to the Duke ADHD Program. Both treatments are eight 90 minute sessions. The research component will involve a pre-treatment assessment and post-treatment assessment. Both assessments will involve adolescents and one caregiver to complete questionnaires over REDCap. Rating scales will include ADHD symptom severity (Conners 3: self and parent report), functional impairment (IRS: self and parent report), executive functioning (BRIEF-2: parent report), emotion dysregulation (DERS: self and parent report), trait mindfulness (FFMQ: self report), organizational skills (BRIEF-2: parent report), treatment satisfaction (self report and parent report) and credibility (self report and parent report). Post-treatment assessments for feasibility will include attendance (measured over the course of treatment) and homework completion rates on a scale of 1 to 5 in which 5 indicates higher homework completion. We will also assess acceptability via individual items on a Likert scale (self report): overall satisfaction, how much was learned about ADHD, usefulness of information learned, content relevance to individual experience, comprehension of strategies, confidence about using strategies, likelihood of using strategies, helpfulness to share with the group, benefits from hearing from other group members, willingness to recommend the same treatment to others, and whether or not treatment was beneficial.

Cuffless PPG Monitor for High Blood Pressure

18+
All Sexes
Miami, FL

This study aims to validate the accuracy and reliability of blood pressure (BP) estimates obtained over 24 hours using a PPG-based chest-patch device compared to the gold standard ambulatory blood pressure monitoring (ABPM) method using an upper arm cuff-based oscillometric BP device, in both hypertensive and normotensive individuals referred by their provider to undergo a 24-hours ABPM for clinical indication. The Awake/Asleep test, which is the primary test recommended for automated wearable cuffless BP devices that are cuff-calibrated (based on the 2023 European Society of Hypertension (ESH) recommendations for the validation of cuffless blood pressure measuring devices), will be conducted in this study. The secondary aim of the study is to assess the feasibility and convenience of the PPG-based device.

fMRI for Cognitive Flexibility

18 - 35
All Sexes
Iowa City, IA

The goal of this basic experimental research study is to examine how the human thalamus supports flexible thinking and behavior. Specifically, the research aims to elucidate how the mediodorsal (MD) thalamus encodes and updates "context"-the mental framework that determines which rules or actions are relevant in a given situation. This work may contribute to understanding why certain psychiatric conditions, such as schizophrenia and ADHD, involve difficulties with cognitive flexibility and control. The primary research questions are: Does the MD thalamus represent the context that organizes how working memory guides task selection? Does the MD thalamus signal when context needs to be updated after a change in task demands? Do these thalamic representations support generalization to new situations or rules? Participants will complete cognitive tasks while undergoing high-resolution brain imaging using 7-Tesla MRI. The investigators will combine behavioral data, computational modeling, and advanced neuroimaging analyses to examine how the thalamus interacts with the cortex during flexible decision-making.
