How is mecasermin given?
Follow all directions on your prescription label. The doctor may occasionally change your child's dose for the best results. Do not use this medicine in larger or smaller amounts or for longer than recommended.
Mecasermin is injected under the skin. You may be shown how to use injections at home. Do not give this medicine if you do not understand how to use the injection and properly dispose of used needles and syringes. Do not inject mecasermin into a vein.
Mecasermin is usually given twice per day, shortly before or after the child eats a meal or snack. Skip a dose if the child will miss a meal. Mecasermin can cause low blood sugar, which may be worse if the child does not eat.
Tell your doctor if your child has any changes in weight. Mecasermin doses are based on weight and any changes may affect the dose.
Your care provider will show you the best places on your child's body to inject mecasermin. Use a different place each time you give an injection. Do not inject into the same place two times in a row.
Do not use the medicine if it looks cloudy or has particles in it. Call your pharmacist for new medicine.
While using mecasermin, your child may need frequent examinations and medical tests. The child's blood sugar may also need to be checked often.
Watch your child for signs of low blood sugar (hypoglycemia). Symptoms include headache, hunger, sweating, confusion, irritability, dizziness, or feeling shaky. Always keep a source of sugar available in case the child has low blood sugar. Sugar sources include fruit juice, hard candy, crackers, raisins, and non-diet soda. Be sure your family and close friends know how to help the child in an emergency.
Keep track of how many days in a row your child has had low blood sugar symptoms after a mecasermin injection.
Call the doctor if hypoglycemia symptoms do not get better after eating or drinking a sugar source.
Use a disposable needle and syringe only once. Follow any state or local laws about throwing away used needles and syringes. Use a puncture-proof "sharps" disposal container (ask your pharmacist where to get one and how to throw it away). Keep this container out of the reach of children and pets.
Store this medicine in the refrigerator. Protect from light and do not freeze. Throw away the vial 30 days after opening it, even if it still contains unused mecasermin.
