This medication is used to treat growth failure due to a lack of growth hormone. Growth hormone is normally produced in the brain by a certain gland (pituitary gland) and has various effects on development in the body. A lack of growth hormone in children results in slowed growth and short height for the child's age. Somatrogon works by providing more growth hormone, which may help the long bones (such as the arms and legs) grow longer.

Read the Patient Information Leaflet and Instructions for Use if available from your pharmacist before you start using somatrogon and each time you get a refill. Ask your health care professional how to prepare and use this medication. If you have any questions, ask your doctor or pharmacist.

Inject this medication under the skin as directed by your doctor, usually once weekly. The injection is given in the stomach (abdomen), thighs, buttocks, or upper arms. The dosage is based on your medical condition, weight, and response to treatment.

Before using, check this product for particles or discoloration. If either is present, do not use the liquid.
