Intuniv 1mg (Guanfacine Hydrochloride ER) is a non-stimulant treatment for attention deficit hyperactivity disorder (ADHD). It is a long-acting form of guanfacine, which had previously been used to treat high blood pressure.
Intuniv 1mg (Guanfacine Hydrochloride ER), known as guanfacine in its generic form, is a once-daily, non-stimulant medication used to treat ADHD in children ages 6-12, and adolescents. It is commonly used on its own as a monotherapy, or as a complementary treatment alongside stimulant medications, educational interventions, and therapies.
Intuniv 1mg (Guanfacine Hydrochloride ER) Warnings and Side Effects
Side effects of Intuniv most commonly include somnolence (which can occur in up to 38 percent of patients), headaches, fatigue, upper abdominal pain, nausea, lethargy, dizziness, irritability, decreased blood pressure, and decreased appetite.
Although somnolence occurs in a large number of children when they start taking Intuniv, it seems to get better as they continue to take it. For some children, this is a benefit, as it helps them fall asleep if they are given their dose at bedtime (Intuniv can either be given in the morning or the evening).
Warnings about Intuniv 1mg (Guanfacine Hydrochloride ER) include:
Intuniv should be used cautiously if your child is at risk for low blood pressure, bradycardia (low heart rate), heart block, or syncope (fainting), and those also taking ketoconazole, rifampin, valproic acid, antihypertensive drugs, or CNS depressants (sedatives, antipsychotics, etc.).
Intuniv should not be taken with a high-fat meal. It can be taken with water, milk, or other liquids.
Intuniv should be discontinued slowly, by decreasing or tapering the dose over several weeks, and should not be stopped suddenly.
Dosage of Intuniv for ADHD
As with all medications, follow your Intuniv prescription instructions exactly. Intuniv is an extended-release tablet taken once daily in the morning or evening at approximately the same time each day. Tablets are available in 1mg, 2mg, 3mg, and 4mg dosages.
Intuniv should not be taken with a high-fat meal. This can speed up the release of medication, and increase the risk of side effects. Tablets should be swallowed whole, and never crushed or chewed.
The optimal dosage varies patient by patient. Your doctor may adjust your dosage weekly by 1mg increments until you or your child experiences the best response — that is, the lowest dosage at which you experience the greatest improvement in symptoms without side effects.
Precautions Associated with Intuniv 1mg (Guanfacine Hydrochloride ER)
Store Intuniv 1mg (Guanfacine Hydrochloride ER) in a secure place out of the reach of children, and at room temperature. Do not share your Intuniv prescription with anyone, even another person with ADHD. Sharing prescription medication is illegal, and can cause harm.
You should not take Intuniv if you have an allergy to Intuniv or any of its ingredients. You should use caution taking Intuniv if you have kidney problems, a history of fainting, heart problems, or a history of stroke.
Avoid becoming overheated or dehydrated while taking Intuniv.
If you’re thinking of having a child, discuss the use of Intuniv with your doctor. Animal studies indicate a potential risk of fetal harm. It is not known if Intuniv is passed through breastmilk, so it is recommended that mothers do not nurse while taking it.
