ADHD Home > Intuniv Warnings and Precautions

Intuniv lowers heart rate and blood pressure, which can cause problems in children who already have low blood pressure or a slow heart rate. Other warnings and precautions with Intuniv apply to children who have a history of fainting, an irregular heart rhythm, or any allergies. To ensure safe treatment with this drug, review your child's complete medical history with your healthcare provider.

What Should I Tell My Child's Healthcare Provider?

Before your child takes Intuniv™ (guanfacine ER), tell the healthcare provider if your child has:
  • Low blood pressure (orthostatic hypotension)
  • An irregular heart rhythm (arrhythmia)
  • A slow heart rate (bradycardia)
  • A history of fainting
  • Any allergies, including to food, dyes, or preservatives.
Also, let your healthcare provider know if your child is pregnant or breastfeeding. In addition, tell your healthcare provider about all of the medicines your child takes, including prescription and nonprescription medicines, vitamins, and herbal supplements.

Specific Intuniv Warnings and Precautions

Some precautions and warnings to be aware of with Intuniv include the following:
  • Intuniv decreases both heart rate and blood pressure. For most children, these changes are too minor to cause any problems. However, this could cause problems for some children, especially those who already have low blood pressure or a slow heart rate.
The healthcare provider should check your child's blood pressure and heart rate before starting the medication, after any dose increases, and periodically thereafter.
  • Intuniv often causes drowsiness. Make sure teens do not drive or operate heavy machinery until they know exactly how this medication will affect them.
  • People taking this drug should not drink alcoholic beverages.
  • Intuniv is considered a pregnancy Category B medication. This means that it is probably safe for use during pregnancy, although the full risks are currently unknown. Be sure to talk with your child's healthcare provider about the risks and benefits of using this drug when pregnant (see Intuniv and Pregnancy).
  • It is unknown if Intuniv passes through breast milk. Therefore, if your child is breastfeeding or plans to start, discuss this issue with the healthcare provider first (see Intuniv and Breastfeeding for more information).
