After 1 week, your child’s doctor may gradually increase the dose to a maximum dose of 0.12 mg per kg of body weight, injected twice a day. This increase will depend on how well your child tolerates the medication.

Are there any other precautions or warnings for this medication?
Before you begin using a medication, be sure to inform your doctor of any medical conditions or allergies you may have, any medications you are taking, whether you are pregnant or breast-feeding, and any other significant facts about your health. These factors may affect how you should use this medication.
Driving and operating machinery: Mecasermin can cause blood glucose levels to fall, causing dizziness, drowsiness, or difficulty concentrating, affecting your ability to drive and perform other potentially hazardous activities. Avoid participating in any high-risk activities for 2 to 3 hours after using mecasermin, especially while starting treatment with this medication.
Low blood glucose (hypoglycemia): Mecasermin has effects similar to insulin, in that it causes blood sugar to be used by the body for energy and growth. As a result, low levels of glucose in the blood can occur. To help reduce the likelihood of this happening, mecasermin should not be given without a meal or snack.
Symptoms of mild to moderate hypoglycemia may occur suddenly and can include cold sweat, nervousness or shakiness, fast heartbeat, headache, hunger, confusion, lightheadedness, weakness, and numbness or tingling of the tongue, lips, or fingers. Mild to moderate hypoglycemia may be treated by eating foods or drinks that contain sugar.
If your child has diabetes, it may be necessary to reduce medications used to treat the diabetes, in order to prevent episodes of dangerously low blood glucose. Blood sugar may need to be checked more frequently.
Scoliosis: For children who have scoliosis, rapid growth may cause scoliosis to worsen. Your doctor will monitor for progression of scoliosis.
Tumour growths: Tumours are caused by uncontrolled growth of specific types of cells. They may be non-cancerous (benign) or cancerous (malignant). Children and adolescents treated with mecasermin may develop tumours. If you experience or notice that your child is experiencing unusual swellings or growths, contact your doctor as soon as possible.
Pregnancy: This medication should not be used during pregnancy unless the benefits outweigh the risks. If you become pregnant while taking this medication, contact your doctor immediately.
If you could become pregnant, you should have a pregnancy test before starting to use this medication.
Breast-feeding: It is not known if mecasermin passes into breast milk. If you are breast-feeding and are taking this medication, it may affect your baby. Talk to your doctor about whether you should continue breast-feeding.
Children: The safety and effectiveness of using this medication have not been established for children less than 2 years of age.
