Buy Intuniv XR Online

Intuniv XR is a once-daily, extended-release guanfacine tablet used in ADHD care. It can be ordered online, with current pricing shown during checkout and strength choices matched to the directions from your clinician. Common tablet strengths include 1 mg, 2 mg, 3 mg, and 4 mg, so the exact dose on the label should guide what you select.

Guanfacine extended-release is a non-stimulant option, which means it works differently from amphetamine- or methylphenidate-based ADHD medicines. Many people consider it when impulsivity, hyperactivity, emotional reactivity, or evening rebound symptoms are part of the treatment conversation. BorderFreeHealth offers U.S.-from-Canada service for customers who are paying out of pocket or comparing cash costs.

Price, Strengths, and Ordering Intuniv XR

The Intuniv XR price depends on the tablet strength, quantity, and whether the dispensed medicine is the brand product or an approved generic guanfacine extended-release tablet. During ordering, choose the strength that matches the directions on your medication label or clinician instructions. Do not switch between strengths, combine tablets, or change timing unless your care team has told you to do so.

Commonly supplied strengths are Intuniv XR 1 mg tablets, Intuniv XR 2 mg tablets, Intuniv XR 3 mg tablets, and Intuniv XR 4 mg tablets. Generic guanfacine ER 1 mg, 2 mg, 3 mg, and 4 mg tablets may also be used when appropriate. Tablet appearance can vary by manufacturer, so the pharmacy label is more reliable than color or shape alone.

If you are comparing Intuniv XR Canadian pricing with local cash-pay totals, look at the full order amount rather than only the per-tablet figure. Strength, tablet count, and repeat refill timing all affect the final cost. If prompt, express shipping is offered at checkout, select it only if it fits your timing needs.

How This ADHD Medicine Works

Intuniv XR contains guanfacine in an extended-release form. Guanfacine is an alpha-2A adrenergic agonist, a nerve-signal modulator that affects pathways involved in attention, impulse control, and behavioral regulation. Because the tablet releases medication gradually, it is intended for once-daily use rather than short bursts of symptom coverage.

This medicine is used for attention-deficit/hyperactivity disorder, often called ADHD. It is not a stimulant and does not work the same way as Adderall, Focalin, Concerta, or other stimulant medicines. Some treatment plans use guanfacine ER alone, while others pair it with another ADHD medicine when a clinician decides the combination is appropriate.

Who May Be Considered for Guanfacine ER

Guanfacine ER is often discussed when ADHD symptoms include impulsive behavior, overactivity, frustration reactivity, sleep-related concerns, or difficulty settling after school or work. The brand labeling in the United States focuses on pediatric ADHD use, while clinicians may sometimes use guanfacine ER in adults when they judge it suitable. Adult use should be individualized because sleepiness, blood pressure, heart rate, and other health factors matter.

This medicine may not be a good fit for someone who has had an allergic reaction to guanfacine or any tablet ingredient. Extra caution is also important for people with a history of fainting, very low blood pressure, slow heart rate, dehydration episodes, or heart conduction problems. A simple list of current medicines, supplements, and over-the-counter sleep aids can help identify avoidable risks.

When ADHD overlaps with anxiety, depression, or other mental health concerns, one medicine may not address every symptom. The Mental Health Products category and Mental Health Articles section can help you organize broader treatment questions for your next appointment.

Taking Extended-Release Tablets Safely

Intuniv XR is generally taken once daily at a consistent time, often morning or evening depending on sedation and daily routine. The tablet should be swallowed whole with water. Crushing, chewing, or splitting an extended-release tablet can change how the medicine is released and may raise the chance of side effects.

Some labeling advises avoiding a high-fat meal close to the dose because food can affect absorption. If a dose is missed, many labels advise returning to the regular schedule rather than doubling the next dose. After several missed doses, the body may need a slower restart, so ask a clinician or pharmacist for situation-specific instructions.

Quick tip: Record the exact strength as “guanfacine ER 2 mg” or “Intuniv XR 3 mg” in your medication list.

Dose changes are usually gradual because guanfacine can affect alertness, pulse, and blood pressure. Early treatment and dose increases are the times when dizziness, tiredness, or lightheadedness are more likely to appear. Keeping dose timing consistent makes it easier to tell whether a change is helping or causing problems.

Side Effects, Warnings, and Monitoring

Common Intuniv XR side effects include sleepiness, tiredness, dizziness, dry mouth, constipation, headache, nausea, and lower energy. These effects may be stronger when treatment starts or after the dose increases. Some people feel better taking the medicine at a different time of day, but timing changes should be discussed first if they affect school, work, driving, or caregiving responsibilities.

More serious concerns include fainting, very low blood pressure, slow heart rate, and severe drowsiness. Sudden discontinuation can cause rebound high blood pressure, so stopping is usually planned with a taper. Seek prompt medical help for fainting, chest pain, severe weakness, shortness of breath, or behavior changes that feel unusual or unsafe.

Why it matters: Dehydration, hot weather, alcohol, and quick position changes can make lightheadedness more likely.

Guanfacine is processed partly through CYP3A4 enzymes. Strong CYP3A4 inhibitors can raise guanfacine levels, while strong inducers can lower them. Certain antibiotics, antifungals, seizure medicines, blood-pressure medicines, sedatives, antihistamines, and alcohol may require closer monitoring or a medication adjustment. Share all current medicines before starting, stopping, or adding anything new.

People taking other ADHD or mental health medicines should watch for overlapping effects such as sleep disturbance, appetite change, irritability, sedation, or blood-pressure changes.

Brand Intuniv XR vs Generic Guanfacine ER

Intuniv XR is the brand name for guanfacine extended-release tablets. Generic guanfacine ER contains the same active ingredient and is intended to deliver guanfacine in an extended-release tablet form. The manufacturer, tablet markings, color, and inactive ingredients may differ, so always use the label on the bottle to identify what was supplied.

Brand and generic naming can differ by country and pharmacy supply. That does not change the practical buying question: the active ingredient, strength, release type, and directions must match what your clinician intended. If a refill looks different from the last one, contact the dispensing pharmacy before taking it, especially if the strength or release wording seems different.

Some people ask whether guanfacine ER is the same as immediate-release guanfacine. It is not interchangeable tablet-for-tablet. Extended-release guanfacine is designed for slow release across the day, while immediate-release guanfacine has different dosing behavior and should not be substituted without specific medical direction.

Storage, Travel, and Refill Checks

Store Intuniv XR tablets at controlled room temperature in a dry place, away from excess heat and moisture. Keep the medicine in its original container so the label, strength, and instructions remain easy to verify. If the bottle includes a desiccant packet, leave it inside and do not swallow it.

When traveling, keep tablets in carry-on luggage rather than a checked bag or hot car. Time-zone changes can disrupt once-daily routines, so plan the schedule before travel days. A phone reminder can help prevent missed doses, especially during school breaks, shift changes, or vacations.

Before each refill, compare the label against your current dose, timing, and tablet strength. Also note any recent fainting, dizziness, unusual fatigue, constipation, mood changes, or new medicines. These observations can make follow-up discussions more useful and help prevent small problems from becoming larger ones.

How It Compares With Other ADHD Options

Non-stimulant ADHD medicines include guanfacine ER, clonidine ER, and atomoxetine. Stimulant medicines are also widely used and often have different onset, appetite, sleep, and cardiovascular considerations. Guanfacine ER may be considered when calming overactivity and impulsivity are important goals, but the tradeoff can be sedation or lower blood pressure.

Focalin XR and Intuniv together is a common discussion point because some clinicians combine a stimulant with guanfacine ER. Combination treatment is not something to self-start. It requires a clear plan for timing, monitoring, appetite, sleep, mood, pulse, and blood pressure.

When several conditions are being treated, it helps to separate the goal of each medicine. An ADHD medicine may target attention and impulse control, while an antidepressant or anxiety medicine may target mood, worry, or obsessive symptoms. Keeping a written symptom log for a few weeks can show whether changes are meaningful without making everyday life feel over-measured.
