Intuniv XR How to Take

Intuniv XR (Guanfacine) belongs to the class of medications called alpha adrenergic agonists. It is used alone and with stimulant medications to treat symptoms of attention-deficit/hyperactivity disorder (ADHD) in children between the ages of 6 and 17 years. It should be used in combination with other, non-drug measures such as counselling to treat the symptoms of ADHD. Intuniv XR (Guanfacine) is different from other medications used to treat ADHD, because it is not a stimulant medication like Methylphenidate or Dextroamphetamine. The way that Intuniv XR (Guanfacine) works to treat the symptoms of ADHD has not yet been determined.

Intuniv XR (Guanfacine) may be available under multiple brand names and/or in several different forms. Any specific brand name of Intuniv XR (Guanfacine) may not be available in all of the forms or approved for all of the conditions discussed here. As well, some forms of Intuniv XR (Guanfacine) may not be used for all of the conditions discussed here.

Your doctor may have suggested Intuniv XR (Guanfacine) for conditions other than those listed in these drug information articles. If you have not discussed this with your doctor or are not sure why you are taking Intuniv XR (Guanfacine), speak to your doctor. Do not stop taking Intuniv XR (Guanfacine) without consulting your doctor.

Do not give Intuniv XR (Guanfacine) to anyone else, even if they have the same symptoms as you do. It can be harmful for people to take Intuniv XR (Guanfacine) if their doctor has not prescribed it.

Discreet Packaging

Your privacy is important. That's why we send your medication inside a plain delivery box so no one will know what's inside.

Intuniv XR Dosage

The recommended starting dose for Intuniv XR (Guanfacine) is 1 mg taken once daily. Your child's doctor may gradually increase the dose, based on the effectiveness and side effects of the medication. The maximum daily dose for children 6 to 12 years of age is 4 mg, taken once a day. For adolescents 13 to 17 years of age, the maximum daily dose is 7 mg when used alone or 4 mg when used in combination with another medication for ADHD.

Many things can affect the dose of medication that a person needs, such as body weight, other medical conditions, and other medications. If your doctor has recommended a dose different from the ones listed here, do not change the way that you are taking the medication without consulting your doctor.

Intuniv XR (Guanfacine) should be swallowed whole with a small amount of liquid. Do not chew or crush the tablet as this will cause the medication to be absorbed into the body all at once, possibly causing more side effects.

Avoid taking Intuniv XR (Guanfacine) along with a meal that is high in fat.

It is important that Intuniv XR (Guanfacine) be taken exactly as prescribed by your doctor. If Intuniv XR (Guanfacine) is stopped suddenly, both blood pressure and heart rate can increase. If you feel the need to stop the medication, it should be done gradually under supervision of your doctor.

If you miss a dose, take it as soon as possible and continue with your regular schedule. If it is almost time for your next dose, skip the missed dose and continue with your regular dosing schedule. Do not take a double dose to make up for a missed one. If you are not sure what to do after missing a dose, contact your doctor or pharmacist for advice. If more than 2 doses in a row are missed, contact your doctor for instructions, since you may need to restart at a lower dose.

Store Intuniv XR (Guanfacine) at room temperature, protect it from light and moisture, and keep it out of the reach of children.

Do not dispose of medications in wastewater (e.g. down the sink or in the toilet) or in household garbage. Ask your pharmacist how to dispose of medications that are no longer needed or have expired.

Intuniv XR Warnings

Before you begin using a medication, be sure to inform your doctor of any medical conditions or Allergies you may have, any medications you are taking, whether you are pregnant or breast-feeding, and any other significant facts about your health. These factors may affect how you should use Intuniv XR (Guanfacine).

Abnormal heart rhythms: Intuniv XR (Guanfacine) can cause abnormal heart rhythms. Certain medications (e.g., Sotalol, quinidine, Chlorpromazine, Pimozide, moxifloxacin, Mefloquine, pentamidine, Tacrolimus) can increase the risk of a type of abnormal heart rhythm called QT prolongation, and should not be used in combination with Intuniv XR (Guanfacine). If you have been told that your child is at an increased risk of developing an abnormal heart rhythm, discuss with your doctor how Intuniv XR (Guanfacine) may affect their medical condition, how their medical condition may affect the dosing and effectiveness of Intuniv XR (Guanfacine), and whether any special monitoring is needed.

Blood pressure and heart rate: Intuniv XR (Guanfacine) may cause decreases in blood pressure or heart rate. If you have low blood pressure or are just starting to take Intuniv XR (Guanfacine), you should move slowly when you are rising from a sitting or lying down position to reduce the risk of dizziness.

Drowsiness and reduced alertness: Intuniv XR (Guanfacine) may affect the mental or physical abilities needed to perform tasks that require special attention. Have your child avoid riding a bike, operating machinery, or performing other hazardous tasks until you have determined how Intuniv XR (Guanfacine) affects your child.

Kidney function: Kidney Disease or reduced kidney function may cause Intuniv XR (Guanfacine) to build up in the body, causing side effects. If your child has reduced kidney function or kidney disease, discuss with your doctor how Intuniv XR (Guanfacine) may affect their medical condition, how their medical condition may affect the dosing and effectiveness of Intuniv XR (Guanfacine), and whether any special monitoring is needed.

Liver function: Liver disease or reduced liver function may cause Intuniv XR (Guanfacine) to build up in the body, causing side effects. If your child has liver problems, discuss with their doctor how Intuniv XR (Guanfacine) may affect their medical condition, how your medical condition may affect the dosing and effectiveness of Intuniv XR (Guanfacine), and whether any special monitoring is needed.
