  • Do NOT discontinue abruptly: taper dose by no more than 1 mg every 3-7 days to avoid rebound hypertension
  • Syncope: may occur, especially with dehydration or concomitant antihypertensives
  • Cardiac conduction abnormalities: use caution in patients with heart block

Contraindications

  • Known hypersensitivity to guanfacine
FDA Approved: 2009

FDA-approved as monotherapy or adjunctive therapy to stimulants for pediatric ADHD (ages 6-17). The immediate-release formulation (Tenex) is FDA-approved only for hypertension.

Frequently Asked Questions

What is the difference between stimulant and non-stimulant ADHD medications?

Stimulant medications (methylphenidate and amphetamine-based) increase dopamine and norepinephrine levels and are considered first-line treatments for ADHD. They work quickly, often within 30-60 minutes.

Non-stimulant medications work through different mechanisms and typically take several weeks to reach full effect. They may be preferred when stimulants cause side effects, for patients with substance abuse history, or when a non-controlled option is desired.

What is the difference between immediate-release and extended-release?

Immediate-release (IR) medications work quickly but wear off in 3-6 hours, requiring multiple doses per day. Extended-release (ER/XR) medications use special delivery systems to release the drug gradually throughout the day, typically lasting 8-16 hours with a single dose.

Extended-release formulations offer more consistent symptom control and better adherence since you only need to take them once daily.

Are ADHD medications addictive?

Stimulant ADHD medications are DEA Schedule II controlled substances with potential for abuse and dependence. However, when taken as prescribed under medical supervision, the risk of addiction is low.

Research suggests that treating ADHD with medication may actually reduce the risk of substance abuse. Non-stimulant medications have little to no abuse potential.

How do I know which ADHD medication is right for me?

The best ADHD medication varies by individual and depends on factors like symptom severity, co-existing conditions, lifestyle, side effect tolerance, and personal preference.

A healthcare provider will typically start with a first-line medication at a low dose and adjust based on response. Finding the right medication and dose often requires patience and close communication with your doctor.

What are the most common side effects?

Common side effects of stimulant ADHD medications include decreased appetite, insomnia, headache, dry mouth, increased heart rate, and nervousness.

Non-stimulant medications may cause drowsiness, upset stomach, decreased appetite, and mood changes. Most side effects are mild and may diminish over time. Always discuss side effects with your healthcare provider.

Can adults take ADHD medication?

Yes. Many ADHD medications are FDA-approved for adults, and medication can be highly effective for adult ADHD.

Adults may need different dosing than children, and their healthcare provider will consider factors like cardiovascular health, other medications, and lifestyle when choosing a treatment.
