About growth hormone

What is growth hormone?

Hormones are chemical messengers produced in one part of the body that travel to another part of the body to create some sort of change. Growth hormone is made in the pituitary gland at the base of the brain and is very important in helping children grow. It also helps the body in other ways besides growing taller, like; muscle development, helping bones reach their full density, even helping in your body's metabolic processes.

How does growth hormone work?

When growth hormone is released from the pituitary gland, it makes the liver release a second hormone called insulin-like growth factor-1 (IGF-1). Together, growth hormone and IGF-1 signals tell the bones, muscle and many other organs and tissue to grow by adding more cells. The growth of the bones also requires that bone cells add minerals such as calcium and phosphate, which results in bones that are strong and long.

What is Norditropin®?

Norditropin® is a man-made form of growth hormone called "recombinant human growth hormone." Although it's made in a lab, it is identical to the growth hormone your body makes.

What is Norditropin® approved to treat?

Norditropin® is indicated for the treatment of growth failure due to growth hormone deficiency in children. It is also indicated to help children with short stature due to Noonan syndrome or Turner syndrome grow taller. And it is approved to help children with short stature born small for gestational age who did not experience catch-up growth by the time they were 2-4 years of age. Norditropin® is also indicated in adults who do not make enough growth hormone.

What causes slow growth in children?

A child's growth is not just about how tall they are going to end up as adults. Growth in children is a very important sign of their overall health. So when a child is not growing as he or she should, it could be a sign of some underlying health problem. Some health problems that may affect a child's growth could be nutritional in nature or they could have one of many different genetic disorders. Because there is such a range of possibilities, it is important that a child's height is measured often. That way if any problems do come up they can be identified and taken care of early.

What is growth hormone deficiency?

A deficiency means there is not enough of something. Growth hormone deficiency means just that, your body is not making enough growth hormone.

What could happen if growth hormone deficiency is not treated?

If growth hormone deficiency is not treated in children, it may prevent them from reaching their full height potential. Adults who are not treated for GHD may have changes in the body from the weakening of bones and muscles, even increase of fat and higher cholesterol levels.

How is growth hormone deficiency diagnosed?

Usually an endocrinologist (a doctor who specializes in the study of the hormone system in your body) will be able to tell if you have growth hormone deficiency. The doctor will ask many questions about your health and growth history and about the health and growth history of your family. You will have a physical exam. They may also order a growth hormone stimulation test, or "stim" test.

There are different types of growth hormone stimulation tests. Some are able to measure the level of growth hormone when it is at its highest level, for example, after sleep or exercise, because both of these activities increase the level of growth hormone. Another type of test uses a medicine to make the pituitary gland produce a large amount of growth hormone. If the pituitary does not produce growth hormone in response to this "stimulation," it is a sign that the person has a deficiency.

Why is Norditropin® given by injection?

Because growth hormone is a type of protein, the acids in your stomach would break it down for digestion, just like protein in foods. In a "broken-down" state, it would not be able to help you grow. The short answer is that growth hormone has to be injected so that it can work properly.

Why is Norditropin® given every day?

Growth hormone is produced by the body every single day, with most being produced at night. Taking injections every day keeps the level of growth hormone steady, so it is closest to how the body normally works. Your doctor will prescribe the right amount you will need to keep a steady level in your body. Remember, it's important to take your medication just the way you were told in order for it to work the best.

What if I forget a dose of Norditropin®?

If you miss a dose, take it as soon as you remember. If it is almost time for your next dose, skip the missed dose. Just take the next dose at your regular time. Do not take two doses at the same time unless your healthcare provider tells you to.

What if I inject too much growth hormone?

It is important to take Norditropin® exactly as the doctor has directed. If you take too much, tell your doctor right away.

When will I start to see results from Norditropin®?

Usually you see the greatest results within the first year, but it might also take 6 months before you see an increase in growth rate. After the first year of therapy, the speed at which you are growing generally begins to level off to the average rate of healthy children. Also, there tends to be greater catch up growth with patients who start at a younger age.

How much will I grow?

That all depends on what your target height is. Target height is based upon how tall your mom and dad are. Some studies have shown that the earlier you start, the better you respond to treatment.

How long will I have to be on Norditropin®?

Not everyone stays on growth therapy for the same length of time. It depends on what your doctor thinks is best for you. Your doctor or nurse can best answer this question for you. It is important that you don't stop taking your growth hormone until your doctor says it is time.

How can I get most out of treatment with Norditropin®?

The most important thing to remember is to take your injection exactly the way your doctor or nurse tells you to. Eating well-balanced meals and getting plenty of exercise are also important for staying healthy.

How long has Norditropin® been around?

Norditropin® was approved for use in the United States in 1995. Novo Nordisk, the company that makes Norditropin®, is a trusted leader in endocrinology. Novo Nordisk has done drug research and development for 80 years, with 40 of those years focused in the growth hormone arena.

How safe is Norditropin® to use?

The safety profile of Norditropin® has been established in many clinical studies conducted around the world. In fact, one of our studies followed patients for up to 13 years. The most common side effects of Norditropin® include headaches, muscle pain, joint stiffness, high blood sugar (hyperglycemia), sugar in your urine (glucosuria), swollen hands and feet due to fluid retention and redness and itching in the area you inject.

These are not all the possible side effects of Norditropin®. Though not common, some of the more serious side effects of Norditropin® include: return of tumor or cancerous growths and high risk of death in children with Prader-Willi syndrome who are severely obese or have breathing problems including sleep apnea. For more information, ask your healthcare provider or pharmacist. For full Prescribing Information click here.

Call your healthcare provider for medical advice about side effects. You may report side effects to the FDA at 1-800-332-1088. You may also report side effects to Novo Nordisk at 1-888-NOVO-444 (1-888-668-6444).

What makes Norditropin® devices easy to use?

Norditropin® pens are designed to be easy to learn to use. The 5- and 10-mg FlexPro® pens do not require refrigeration after initial use, so you can take them almost anywhere you're going. The FlexPro® pen is designed to be easy to hold and requires little thumb reach, making it easier to give yourself an injection. A simple "click" tells you that the medicine has left the pen.

How is Norditropin® stored? Can I travel with it?

Like most other growth hormone, Norditropin® pens come refrigerated and each one must be kept that way until it is used the first time. After that, the FlexPro® 5- and 10-mg pens can be left at room temperature (up to 77º) for up to 3 weeks after first use. No other growth hormone product can do that. Remember, the FlexPro® 15 mg and the NordiFlex® 30 mg pen have to stay in the refrigerator in between injections.

Will I have to mix and load cartridges?

FlexPro® and NordiFlex® pens come pre-mixed and pre-loaded, so you have 2 less things to worry about.

How big are the needles on Norditropin® devices?

Norditropin® pens use NovoFine® needles, which are very short and thin.
They're not like the needles you're used to seeing at the doctor.*

*Needles are sold separately and may require a prescription in some states.

What if I can't pay for my medication?

Novo Nordisk, the maker of Norditropin®, offers a lot of different ways to help patients get, and stay on, therapy including:
  • NordiSure™—a co-pay assistance program that covers up to $125 of your co-pay each month
  • Patient Assistance Program (PAP)—provides free product to eligible patients that show financial need
  • JumpStart™—Provides free Norditropin® at the beginning of therapy, or in special circumstances later in therapy, to make sure patients receive treatment
