How should I use mecasermin rinfabate (Iplex)?

Use this medication exactly as prescribed by your doctor. Do not use it in larger amounts or for longer than recommended. Follow the directions on your child's prescription label.

Your child's doctor may occasionally change the dose to make sure your child gets the best results from this medication.

Mecasermin rinfabate is given as an injection (shot) under the skin in your child's upper arm, upper thigh, stomach area, or buttocks. Never inject the medicine into a muscle or a vein. Your doctor, nurse, or pharmacist will give you specific instructions on how and where to inject this medicine. Do not inject your child at home if you do not fully understand how to give the injection and properly dispose of used needles and syringes.

Use a different place in the injection skin area each time you give an injection. Your care provider will show you the places on your child's body where you can safely inject the medication. Do not inject into the same place two times in a row.

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.

Do not draw the mecasermin rinfabate dose into a syringe until you are ready to give your child an injection. Do not use the medication if it has changed colors or has any particles in it. Call your doctor for a new prescription.

Use each disposable needle only one time. Throw away used needles in a puncture-proof container (ask your pharmacist where you can get one and how to dispose of it). Keep this container out of the reach of children and pets.

Your child may need to eat or restrict certain foods while using this medication. Follow the doctor's instructions about diet and medication.

To be sure this medication is helping your child's condition, the child's blood will need to be tested on a regular basis. An eye exam may also be needed. Do not miss any scheduled appointments.

Store this medication in the freezer until you are ready to use it. It is best to keep the medicine in a deep freezer at a temperature of 4 degrees below 0 Fahrenheit (or -20 degrees Celsius) so it does not thaw between uses.

When you are ready to use the medication, take it out of the freezer and allow it to thaw at room temperature for 45 minutes. Do not warm the medication with hot water or a microwave. Once the medicine thaws, it must be used within 1 hour.
