Kapvay Warnings and Precautions

You may not be able to safely use Kapvay if you have low blood pressure, a slow heart rate, or an irregular heart rhythm. Other warnings and precautions with Kapvay apply to women who are pregnant or breastfeeding. To help avoid complications, tell your child's healthcare provider about any other medical conditions your child has, as well as any other medications your child is taking.

What Should I Tell My Healthcare Provider?

You should talk with your child's healthcare provider prior to starting treatment with Kapvay™ (clonidine ER) if your child has:
  • Low blood pressure (hypotension)
  • An irregular heart rhythm (arrhythmia)
  • A slow heart rate (bradycardia)
  • A history of fainting
  • Any allergies, including allergies to foods, dyes, or preservatives.
Also let the healthcare provider know if your child is:
  • Pregnant or thinking of becoming pregnant
  • Breastfeeding.
You should also make sure to tell the healthcare provider about any other medicines your child is taking, including prescription and nonprescription medicines, vitamins, and herbal supplements.

Some Kapvay Warnings and Precautions

Some warnings and precautions to be aware of prior to taking this drug include the following:
  • Kapvay decreases both the 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 in those who already have low blood pressure or a slow heart rate. Your child's healthcare provider should check your child's blood pressure and heart rate before starting the medication, after any dose increases, and periodically thereafter.
  • Kapvay often causes drowsiness. Make sure adolescents do not drive or operate heavy machinery until they know exactly how this medication will affect them.
  • People taking Kapvay should not drink alcoholic beverages.
  • Kapvay should not be stopped suddenly, as this might cause dangerously high blood pressure (hypertension), a rapid heart rate (tachycardia), and other symptoms. When stopping this medication, you should gradually reduce the dosage.
  • Kapvay may potentially interact with several other medications (see Kapvay Drug Interactions).
  • Kapvay is considered a pregnancy Category C medication. This means that it may not be safe for use during pregnancy, although the full risks are currently unknown. Make sure to talk with your healthcare provider about the risks and benefits of using Kapvay during pregnancy (see Kapvay and Pregnancy).
  • Kapvay passes through breast milk. Therefore, if you are breastfeeding or plan to start breastfeeding, make sure to talk with your healthcare provider about using Kapvay (see Kapvay and Breastfeeding for more information).
