This is not a list of all drugs or health problems that interact with this drug.
Tell the doctor and pharmacist about all of your child’s drugs (prescription or OTC, natural products, vitamins) and health problems.

Do not start, stop, or change the dose of any drug your child takes without checking with the doctor.

What are some things I need to know or do while my child takes this drug?

All products:

  • Tell all of your child’s health care providers that your child is taking this drug. This includes your child’s doctors, nurses, pharmacists, and dentists.
  • Allergic reactions have happened with this drug. Rarely, some reactions can be very bad or life-threatening. Talk with the doctor.
  • Low blood sugar may happen with this drug. Very low blood sugar can lead to seizures, passing out, long lasting brain damage, and sometimes death. Talk with the doctor.
  • Low blood potassium may happen with this drug. If not treated, this can lead to a heartbeat that is not normal, very bad breathing problems, and sometimes death. Talk with the doctor.
  • Have your child avoid tasks or actions that call for alertness until you see how this drug affects your child. These are things like riding a bike, playing sports, or using items such as scissors, lawnmowers, electric scooters, toy cars, or motorized vehicles.
  • Some diabetes drugs like pioglitazone or rosiglitazone may cause heart failure or make it worse in people who already have it. Using insulin with these drugs may increase this risk. If you also take one of these drugs, talk with the doctor.
  • Be sure your child has the right insulin product. Insulin products come in many containers like vials, cartridges, and pens. Be sure that you know how to measure and get your child’s dose ready. If you have any questions, call the doctor or pharmacist.
  • It may be harder to control your child’s blood sugar during times of stress like when your child has a fever, an infection, an injury, or surgery. A change in level of physical activity or exercise and a change in diet may also affect your child’s blood sugar. Talk with the doctor.
  • Have your child wear disease medical alert ID (identification).
  • If your child can drive, do not let your child drive if his/her blood sugar has been low. There is a greater chance of a crash.
  • Have your child’s blood sugar checked as you have been told by your child’s doctor.
  • Have your child’s blood work checked often. Talk with your child’s doctor.
  • Alcohol may interact with this drug. Be sure your child does not drink alcohol.
