How does this medication work? What will it do for me?
Somatrogon belongs to the class of medications called human growth hormone analogues. Growth hormone is made naturally in our bodies by the pituitary gland and is necessary for stimulating growth in children. Somatrogon is used to treat growth hormone deficiency for children between the ages of 3 and 11 years. It works by replacing the growth hormone that they are unable to produce enough of naturally.

It is injected in the thigh, buttocks, upper arms, or abdomen. It is important to rotate the site of injection in order to minimize the risk of fat wasting at the site of injection. If more than one injection is needed for a full dose, a different injection site should be used for the second injection.
This medication should be clear and colourless to slightly light yellow in colour. If it is cloudy or dark yellow, do not use it. Start a new pen.

Before you begin using a medication, be sure to inform your doctor of any medical conditions or allergies you may have, any medications you are taking, whether you are pregnant or breast-feeding, and any other significant facts about your health. These factors may affect how you should use this medication.
Cancer: As with other growth hormone products, there may be an increased risk of tumour growth, both cancerous and non-cancerous when growth hormone is used by survivors of childhood cancer. Discuss any concerns you may have with your doctor.
Diabetes: Other growth hormone treatments can cause increased levels of blood glucose and decreased glucose tolerance.

Scoliosis: People with scoliosis are at risk of their condition worsening while taking somatrogon. If your child has scoliosis, discuss with your doctor how this medication may affect your medical condition, how your medical condition may affect the dosing and effectiveness of this medication, and whether any special monitoring is needed.
Thyroid function: Other growth hormone treatments may not be as effective if the thyroid gland is not working properly. These treatments can also cause decreased thyroid function.

Pregnancy: This medication should not be used during pregnancy unless the benefits outweigh the risks. If you become pregnant while taking this medication, contact your doctor immediately.
