Somapacitan-beco Injection

Why is this medication prescribed?

Somapacitan-beco injection is used to replace growth hormone (a natural hormone produced by your body) in adults with growth hormone deficiency. Somapacitan-beco injection is also used to replace growth hormone and to increase growth in children 2.5 years of age or older with growth hormone deficiency. Somapacitan-beco is a human growth hormone (hGH) analog. It works by replacing growth hormones that are normally produced in the body.

How should this medicine be used?

Somapacitan-beco comes as a solution (liquid) in a prefilled injection pen to inject subcutaneously (under the skin). It is usually injected once a week, on the same day of the week, and at around the same time of day. Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Use somapacitan-beco exactly as directed. Do not use more or less of it or use it more often than prescribed by your doctor.

If somapacitan-beco injection is given to replace growth hormone in adults, your doctor will probably start you on a low dose of somapacitan-beco and may gradually increase your dose, not more than once every 2 to 4 weeks.

You may receive your first dose of somapacitan-beco injection in your doctor's office. After your first dose, your doctor may allow you or a friend or relative to perform the injections at home. Carefully read the manufacturer's instructions for use that comes with the medication. These instructions describe how to inject a dose of somapacitan-beco. Be sure to ask your doctor or pharmacist if you have any questions about how to inject the medication.

Continue to use somapacitan-beco injection even if you feel well. Do not stop using somapacitan-beco injection without talking to your doctor.

You can inject somapacitan-beco anywhere on the front of your thighs (upper leg), on your stomach except around your navel (belly button), upper arms, or buttocks. Choose a different spot each time you inject your medication.

Always look at somapacitan-beco solution before injecting it. Check that the expiration date has not passed and that the liquid is clear to almost clear and colorless to slightly yellow. The liquid should not contain visible particles. Do not use a pen if it is expired or if the liquid is cloudy or contains particles.

Do not reuse or share pens and needles. Dispose of used pens and needles in a puncture resistant container that is out of the reach of children. Talk to your doctor or pharmacist about how to dispose of the puncture-resistant container.
