How should I use Serostim?

Your dose and brand of somatropin, and how often you use it will depend on the condition you are treating. Follow all directions on your prescription label and read all medication guides or instruction sheets. Use the medicine exactly as directed.

Serostim is injected into a muscle or under the skin. A healthcare provider can teach you how to properly use the medication by yourself.

Do not inject the subcutaneous injection (under the skin) into the same place two times in a row.

Read and carefully follow any Instructions for Use provided with your medicine. Do not use Serostim if you don't understand all instructions for proper use. Ask your doctor or pharmacist if you have questions.

Prepare your injection only when you are ready to give it. Do not shake the medicine. Do not use if the medicine looks cloudy, has changed colors, or has particles in it. Call your pharmacist for new medicine.

If your medicine comes with a syringe, cartridge, or injection pen, use only that device to give your medicine.

You may need frequent medical tests.

Follow any diet plan created for you by your doctor or nutrition counselor to help control your condition.

How you store this medicine will depend on the Serostim brand and the diluent you are using. Ask your pharmacist if you have any questions about proper storage of your medication.

Throw away any Serostim left over after the expiration date on the label has passed.

Use a needle and syringe only once and then place them in a puncture-proof "sharps" container. Follow state or local laws about how to dispose of this container. Keep it out of the reach of children and pets.

What happens if I miss a dose?

Use the medicine as soon as you can, but skip the missed dose if it is nearly time for your next dose. Do not use two doses at the same time.

Call your doctor if you miss more than 3 doses in a row.

Common questions about Serostim

What is the age limit for growth hormone injections?
There is no strict upper age limit for receiving growth hormone injections, as the therapeutic use of this treatment is determined by the underlying medical condition and the patient's specific needs rather than age alone. However, the reasons for prescribing growth hormone and the typical age ranges for treatment differ significantly between children, adolescents, and adults. Continue reading
