Warning

Your child should not use mecasermin rinfabate if your child has cancer, has finished growing (the bone growth plates are closed), or has other causes of growth failure.

This medicine must be given 20 minutes before or after the child eats a meal or snack. Do not use the medicine if the meal or snack is not eaten for any reason. Wait until the child has eaten and 20 minutes have passed before giving the mecasermin rinfabate injection. Mecasermin rinfabate may lower blood sugar levels if it is used without eating.

Always eat a meal or snack 20 minutes before or after injecting mecasermin rinfabate.

Mecasermin rinfabate may cause a bone problem in the top of the upper leg. Get medical attention right away if your child develops a limp or has hip or knee pain.

Know the signs of low blood sugar (hypoglycemia) and how to recognize them in your child. Always keep a source of sugar available in case your child has symptoms of low blood sugar. Sugar sources include orange juice, glucose gel, candy, or milk. Severe hypoglycemia may cause fainting, seizure (convulsions), or death. If your child has severe hypoglycemia and cannot eat or drink, give an injection of glucagon. Your doctor can give you a prescription for a glucagon emergency injection kit and tell you how to give the injection.
