Frequently Asked Questions

Find answers to some of the most common questions about growth hormone-related disorders and treatment with Norditropin® (somatropin [rDNA origin] injection). If you still have questions and can’t find the answers on this website, be sure to ask your doctor.


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.

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 tell the bones, muscle, and many other organs and tissue to grow by adding more cells. The growth of the bones also requires bone cells to 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 and 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 did not make enough growth hormone when they were children or when they became adults.


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?

Lack of treatment for growth hormone deficiency could result in a child being significantly shorter than they otherwise would be when they reach adulthood. Adults who are not treated for GHD may have changes in the body such as weakening of bones, decrease in amount of muscle, and increase in fat and cholesterol.

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. The doctor 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, 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 release 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.

How can I learn more about growth hormone deficiency?

There are several organizations dedicated to education, awareness, and advocacy for people with growth-related disorders. Take a look at the Patient Advocacy Groups.


Will I have to use a syringe?

No; the only delivery devices for Norditropin® [is/are] our FlexPro® pen [and NordiFlex®] pen[s]. With Norditropin®, you never have to deal with a typical syringe.

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 by your doctor 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. Remember that it is important to follow the dosing schedule you were given by your doctor, so do not take 2 doses at the same time unless your health care 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.

How big are the needles on Norditropin® devices?

Norditropin® pens use NovoFine® needles, which are the thinnest needles on the market. They’re not like some of the needles you may be used to seeing at the doctor’s office. Our thinnest NovoFine® needle in the United States is 32 gauge at the tip.a,b

When will I start to see results from Norditropin®?

Usually you see the greatest results within the first year, but it might also take at least 6 months before you see an increase in growth rate. Also, there tends to be greater catch-up growth with patients who start at a younger age. However, individual results may vary, so you should check with your doctor.

How much growth can be expected?

That depends on many factors, including the patient’s target height, which is based on the height of his or her parents. Some studies have shown that the earlier a patient starts, the better they respond to treatment. However, individual results may vary, so you should check with your doctor.

How long will treatment last?

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.
