Humatrope – Somatropin uses, dose and side effects


6 mg / 12 mg / 24 mg powder and solvent for injection , solution


This medicine is called Humatrope and contains growth hormone, also called somatropin. Humatrope is made using a special technology called recombinant DNA technology. It has the same structure as the growth hormone that the body normally produces.

Growth hormone regulates the growth and development of cells in the body. When cell growth in the spine and tubular bones is stimulated, it results in an increase in body length.

In the absence of growth hormone, the addition of growth hormone also results in an increased bone mineral content, increased number and size of muscle cells, and reduced body fat storage.

Humatrope is used for

  • Treatment of children and adolescents with disorders of height growth depending on
    • insufficient release of own growth hormone (growth hormone deficiency)
    • Turner syndrome (female chromosome disorder with no or few X chromosomes missing)
    • chronic kidney disease in children before puberty with delayed growth
    • SGA – small for gestational age, ie short stature in children who are born small in relation to the length of the fetal period and who have not recovered growth at 4 years of age or later
    • Lack of SHOX gene function (genetic disease)
  • Treatment of adults with confirmed growth hormone deficiency that began either in childhood or in adulthood.

Somatropin contained in Humatrope may also be approved for the treatment of other conditions not mentioned in this leaflet. Ask your doctor, pharmacist, or other healthcare professional if you have any further questions, and always follow their instructions.


DO NOT USE Humatrope:

  • If you are allergic (hypersensitive) to somatropin or to any of the other ingredients of Humatrope (eg metacresol, glycerol in the diluent), see section 6.
  • and tell your doctor if you have an active tumor (cancer). Tumors must be inactive and you must have stopped your cancer treatment before starting treatment with Humatrope.
  • If you have already stopped growing (closed growth plate at the end of the tubular bone ) and want to grow further in length. Your doctor will examine you to determine if you still need Humatrope after your legs have stopped growing.
  • If you are very ill and need intensive care after serious heart or abdominal surgery, are treated for multiple injuries after an accident or need mechanical breathing assistance after acute lung problems.

Warnings and cautions

Talk to your doctor or pharmacist before using Humatrope.

If you have a replacement therapy with glucocorticoids, you should contact your doctor regularly, as you may need to adjust your glucocorticoid dose.

If you have been treated for growth hormone deficiency during childhood. Your doctor will re-examine you for growth hormone deficiency to determine if you need further treatment with Humatrope in adulthood.

If you have previously stopped treatment for a tumor. X-rays of the brain may be required before treatment with Humatrope. You should be examined regularly to determine that the tumor has not returned or started to grow.

A higher risk of getting secondary tumors (benign and malignant) has been reported in patients who have survived their cancer and who have been treated with somatropin. Of these secondary tumors, it is especially brain tumors that were the most common.

If you have symptoms such as recurrent or severe headaches with nausea and/or visual disturbances. Talk to your doctor immediately. Your doctor should do an examination of the eyes to see if there are signs of increased pressure in the brain. Depending on the results of this study, treatment with Humatrope may need to be stopped.

If you start to limp or have hip pain. Consult your doctor. During the growth period, bone diseases can develop in the hip.

If you start treatment with Humatrope. Humatrope can affect the amount of thyroid hormone in the blood. If the thyroid hormone level is low, it may reduce the effect of Humatrope. Therefore, regular check-ups of thyroid function should be done regardless of whether you are receiving thyroid hormone treatment or not.

If you are a child. Make sure that the treatment continues until the final length is reached.

If you take a higher dose than prescribed. Somebody parts can be enlarged and roughened e.g. ears, nose, jaw, hands, and feet. Overdose can also cause increased blood sugar and sugar in the urine. Always use the dose recommended by your doctor.

If you have a growth disorder due to kidney damage. Humatrope treatment should be stopped before kidney transplantation.

If you have an acute, serious illness. Your doctor should be informed. Deaths have occurred in patients receiving somatropin in severe diseases.

If you have growth hormone deficiency and also have Prader-Willi syndrome (a congenital disease). Your doctor should check if you have any breathing problems or respiratory infections before starting Humatrope treatment. This is especially true for obese people who have previously had problems with severe breathing disorders (especially during sleep) or have had infections in their lungs or airways. If you experience breathing problems (snoring) during treatment, stop treatment and investigate the cause by your doctor.

Humatrope can affect how the sugar from food and drink is taken care of by the body by intervening in the way the body uses insulin. Therefore, if you are taking Humatrope, your doctor should check that your body is taking care of your sugar properly. If you have diabetes mellitus, your insulin dose may need to be adjusted after starting your Humatrope treatment. Your doctor will check the amount of sugar in your blood and may adjust your diabetes treatment.

If you have a growth disorder due to the length at birth was short in relation to the length of the fetal period. Blood sugar and insulin levels will be checked before starting treatment and then regularly during treatment.

Elderly patients (over 65 years). You may be more sensitive to Humatrope and more likely to experience side effects.

Scoliosis (increased lateral curvature of the spine) can develop in all children who grow rapidly. Signs of scoliosis should be noted during treatment.
