Because Each Child is Unique:

Ask your doctor if INCRELEX® is the appropriate treatment for your child.

INCRELEX® is used to treat children who are very short for their age because their bodies do not make enough insulin-like growth factor-1 (IGF-1). This condition is called Severe Primary IGF-1 Deficiency or SPIGFD. INCRELEX® should not be used instead of growth hormone and has not been studied for use in children under 2 years of age.

Olive's journey

If your child is not growing at a rate that they should be and their growth hormone levels are normal, very low levels of IGF-1 may be the cause. Talk to your doctor about having your child screened for Severe Primary IGF-1 Deficiency. Ask your doctor for more information to find out if INCRELEX® is an appropriate treatment option for your child.

Important Safety Information

Who Should Not Receive INCRELEX®?
Your child should not receive INCRELEX® if your child: is allergic to mecasermin or any of the ingredients in INCRELEX®; has finished growing; has any cancerous tumors or growths; or has a history of cancer. Your child should never receive INCRELEX® through a vein.

What Should I Tell My Child’s Doctor Before My Child Starts INCRELEX®?

Tell your child’s doctor about all of your child’s medical conditions, including if your child: has diabetes; a curved spine (scoliosis); or is pregnant or breast-feeding.

Tell your child’s doctor about all the medicines (prescription and over-the-counter), vitamins, and herbal supplements your child takes. Especially tell your child’s doctor if your child takes insulin or other anti-diabetes medicines; a change in dose maybe needed.

What are the Possible Side Effects of INCRELEX®?
INCRELEX® may cause serious side effects, including:

  • Low blood sugar (hypoglycemia). INCRELEX® may lower blood sugar levels. It is important to only give your child INCRELEX® 20 minutes before or 20 minutes after a meal or snack to reduce the chances of low blood sugar. Do not give your child INCRELEX® if your child cannot eat. Signs of low blood sugar include: dizziness; tiredness; restlessness; hunger; irritability; trouble concentrating; sweating; nausea; and fast or irregular heartbeat. Severe low blood sugar may cause unconsciousness, seizures, or death. Your child should avoid participating in high risk activities (e.g. driving, exercise, etc.) within 2 to 3 hours after the INCRELEX® injection, especially at the beginning of treatment. Your child should always have a source of sugar such as orange juice, glucose gel, candy, or milk available in case symptoms of low blood sugar happen. For severe low blood sugar, if your child is not responsive and cannot drink sugar-containing fluids, you should get emergency medical help for your child right away.
  • Allergic reactions are a serious but common side effect of INCRELEX®. Call your child’s doctor right away if your child gets a rash or hives, which generally appear minutes to hours after the injection and may sometimes occur at many places on the skin. Stop taking INCRELEX® and get medical help right away if your child has trouble breathing or goes into shock, with symptoms like dizziness, pale, clammy skin or passing out. INCRELEX® can also cause reactions at the injection site including: loss of fat (lipoatrophy); increase of fat (lipohypertrophy); pain; redness; or bruising.
  • Increased pressure in the brain (intracranial hypertension). INCRELEX®, like growth hormone, can sometimes cause a temporary increase in pressure within the brain. Symptoms include persistent headache and nausea with vomiting.
  • Enlarged tonsils. Signs include: snoring, difficulty breathing, sleep apnea (a condition where breathing stops briefly during sleep), or fluid in the middle-ear.
  • A bone problem called slipped capital femoral epiphysis. When the top of the upper leg bone (femur) slips apart. Get medical help for your child right away if your child develops a limp or has hip or knee pain.
  • Worsened scoliosis (caused by rapid growth).
  • Tumor Growths. Several cases of cancerous tumors have been observed in children who received INCRELEX®. Tell your doctor immediately if your child develops any new growths or symptoms of cancer.
  • Benzyl alcohol toxicity. Benzyl alcohol, a preservative in INCRELEX®, can cause serious side effects, including death in infants.

The most common side effects of INCRELEX® include:

Low blood sugar (hypoglycemia); injection site reactions; allergic reactions; and enlarged tonsils.

These are not all the side effects of INCRELEX®. Call your child’s doctor if your child has side effects that are bothersome or that do not go away. You may report side effects to FDA at 1-800-FDA-1088.
