How soon INTUNIV will work

Every child is different. The doctor may find the right dose of INTUNIV for your child in the first two to four weeks, or it may take longer. The right dose depends on your child's weight and response to INTUNIV.

The doctor may start with a low dose and slowly increase the dose when starting your child on INTUNIV. It's important to keep taking INTUNIV as prescribed during this time as it may take a few weeks to see improvement in your child's symptoms.

INTUNIV has several dosage strengths

INTUNIV comes in 4 doses—1 mg, 2 mg, 3 mg, and 4 mg

Important information about taking INTUNIV

  • As with any prescription medicine, it is important to follow the doctor's directions when taking INTUNIV. Take INTUNIV exactly as prescribed by the doctor.
  • The doctor may change your child's dose. Do not change your child's dose without talking with the doctor.
  • Do not stop taking INTUNIV without talking with the doctor.
  • INTUNIV should be taken 1 time a day, either alone or in combination with an ADHD stimulant medicine that your child's doctor may prescribe. The doctor will tell you when your child should take INTUNIV, and when to take the ADHD stimulant medicine.
  • Have your child swallow an INTUNIV tablet whole with a small amount of water, milk, or other liquid.
  • Tablets should not be crushed, chewed, or broken before swallowing. Tell the doctor if your child cannot swallow tablets whole.
  • INTUNIV should not be taken with a high-fat meal.
  • Your child's doctor will regularly check your child's blood pressure and heart rate while he or she takes INTUNIV.
  • If your child takes too much INTUNIV, call your local Poison Control Center or go to the nearest emergency room right away.

Can my child take "drug holidays" from ADHD treatment?

"Drug holiday" is a term some parents use when taking their child off ADHD medication during weekends, school holidays, or summer vacations. It's important that your child doesn't take "drug holidays" from INTUNIV unless approved by your child's doctor. If you would like your child to stop taking INTUNIV, talk with your child's doctor first. The dose will have to be gradually reduced, similar to the way it was gradually increased when your child first started to take it.
