Patient leaflet - Norditropin Flexpro 15 mg / 1.5 ml solution for injection in Pre-filled pen
1. What Norditropin® FlexPro® is and what it is used for
Norditropin® FlexPro® contains a biosynthetic human growth hormone called somatropin which is identical to the growth hormone produced naturally in the body. Children need growth hormone to help them grow, but adults also need it for their general health.
Norditropin® FlexPro® is used to treat growth failure in children
•
If they have no or very low production of growth hormone (growth hormone deficiency)
•
If they have Turner syndrome (a genetic
problem which may affect growth)
•
If they have reduced kidney function
•
If they are short and were born small for gestational age (SGA)
•
If they have Noonan syndrome (a genetic problem which may affect growth).
Norditropin® FlexPro® is used as a growth hormone replacement in adults
In adults Norditropin® FlexPro® is used to replace growth hormone if their growth hormone production has been decreased since childhood or has been lost in adulthood because of a tumour, treatment of a tumour, or a disease that affects the gland which produces growth hormone. If you have been treated for growth hormone deficiency during childhood, you will be retested after completion of growth. If growth hormone deficiency is confirmed, you should continue treatment.

3. How to use Norditropin® FlexPro®
Always use this medicine exactly as your doctor has told you. Check with your doctor or pharmacist if you are not sure.
Recommended dose
The dose for children depends on their body weight and body surface area. Later in life, the dose depends on your height, weight, gender and growth hormone sensitivity and will be adjusted until you are on the right dose.
•
Children with low production or lack of
growth hormone:
The usual dose is 0.025 to 0.035 mg per kg
body weight per day or 0.7 to 1.0 mg per m2 body surface area per day
•
Children with Turner syndrome:
The usual dose is 0.045 to 0.067 mg per kg
body weight per day or 1.3 to 2.0 mg per m2 body surface area per day
•
Children with kidney disease:
The usual dose is 0.050 mg per kg body
weight per day or 1.4 mg per m² body surface area per day
•
Children born small for gestational age (SGA):
The usual dose is 0.035 mg per kg body
weight per day or 1.0 mg per m2 body surface area per day until final height is reached. (In clinical trials of short children born SGA doses of 0.033 and 0.067 mg per kg body weight per day have typically been used)
•
Children with Noonan syndrome:
The usual dose is 0.066 mg per kg body
weight per day, however your doctor may decide that 0.033 mg per kg body weight per day is sufficient
•
Adults with low production or lack of growth hormone:
If your growth hormone deficiency continues after completion of growth, treatment should be continued. The usual starting dose is 0.2 to 0.5 mg per day. The dose will be adjusted until you are on the right dose. If your growth hormone deficiency starts during adult life, the usual starting dose is 0.1 to 0.3 mg per day. Your doctor will increase this dose each month until you are getting the dose you need. The usual maximum dose is 1.0 mg per day.
When to use Norditropin® FlexPro®
Inject your daily dose into the skin every evening just before bedtime.
How to use Norditropin® FlexPro®
Norditropin® FlexPro® growth hormone solution comes in a multidose disposable 1.5 ml pre-filled pen.
Full instructions on how to use Norditropin® FlexPro® are given overleaf. The instructional key points are as follows:
•
Check the solution before use by turning the pen upside down once or twice. Do not use the pen if the solution is cloudy or discoloured (see page 8, step A)
•
Norditropin® FlexPro® is designed to be used with NovoFine® or NovoTwist® disposable needles up to a length of 8 mm
•
Always use a new needle for each injection
•
Vary the area you inject so you do not harm your skin
•
To make sure you get the proper dose and do not inject air, check the growth hormone flow before the first injection from a new Norditropin® FlexPro® pen. Do not use the pen if a drop of growth hormone solution does not appear at the needle tip (see pages 10 to 11, steps E to G)
•
Do not share your Norditropin® FlexPro® pen with anyone else.
3
How long you will need treatment for
•
Children with growth failure because of Turner
syndrome, kidney disease, SGA or Noonan syndrome: Your doctor will recommend you continue treatment until you stop growing
•
Children or adolescents who lack growth
hormone: Your doctor will recommend you continue treatment into adulthood
Do not stop using Norditropin® FlexPro® without discussing it with your doctor first.
If you use more Norditropin® FlexPro® than you should
Tell your doctor if you inject too much somatropin. Long-term overdosing can cause abnormal growth and coarsening of facial features.
If you forget to use Norditropin® FlexPro®
Take the next dose as usual, at the normal time. Do not take a double dose to make up for a forgotten dose.
If you stop using Norditropin® FlexPro®
Do not stop using Norditropin® FlexPro® without discussing it with your doctor first.
If you have any further questions on the use of this medicine, ask your doctor or pharmacist.
4. Possible side effects
Like all medicines, this medicine can cause side effects, although not everybody gets them.
Effects seen in children and adults (unknown frequency)
•
Rash; wheezing; swollen eyelids, face or lips; complete collapse. Any of these may be signs of an allergic reaction
•
Headache, eyesight problems, feeling sick (nausea) and being sick (vomiting). These may be signs of raised pressure in the brain
•
Serum thyroxin levels may decrease
•
Hyperglycaemia (elevated levels of blood glucose).
If you get any of these effects, see a doctor as soon as possible. Stop using Norditropin® FlexPro® until your doctor says you can continue treatment.
Formation of antibodies directed against somatropin has rarely been observed during Norditropin® therapy.
Increased levels of liver enzymes have been reported.
Cases of leukaemia and relapse of brain tumours have also been reported in patients treated with somatropin (the active ingredient in Norditropin® FlexPro®), although there is no evidence that somatropin was responsible for this.
If you think you are suffering from any of these diseases, talk to your doctor.
Additional side effects in children
Uncommon (may affect up to 1 in 100 children)
•
Headache
•
Redness, itching and pain in the area of injection
•
Breast enlargement (gynaecomastia).
Rare (may affect up to 1 in 1,000 children)
•
Rash
•
Muscle and joint pain
•
Swollen hands and feet due to fluid retention.
In rare cases, children using Norditropin® FlexPro® have experienced hip and knee pains or have started limping. These symptoms may be a
consequence of the end of the bone having slipped from the cartilage (slipped capital femoral epiphysis) or a disease affecting the top of the thigh bone (osteonecrosis of femoral head including Legg-Calvé disease). Talk to your doctor about persistent pain.
In children with Turner syndrome, a few cases of increased growth of hands and feet compared to height have been observed in clinical trials.
4
A clinical trial in children with Turner syndrome has shown that high doses of Norditropin® can possibly increase the risk of getting ear infections.

Pull off the pen cap.
Check that the growth hormone solution in the pen is clear and colourless by tipping it upside down once or twice. If the solution looks unclear or cloudy, do not use the pen.
Take a new disposable needle. Tear the paper tab off and screw the needle straight onto the pen. Make sure the needle is on tight.
Always use a new needle for each injection. This reduces the risk of contamination, infection, leakage of growth hormone, blocked needles and inaccurate dosing.
Never bend or damage the needle.
