Proper Use

Drug information provided by: IBM Micromedex

A nurse or other trained health professional will give you this medicine. It is given as a shot under your skin, usually in the stomach, thighs, upper arm, or buttocks. You or your caregiver may be trained to prepare and inject this medicine at home. Be sure that you understand how to use the medicine.

If you use this medicine at home, you will be shown the body areas where this shot can be given. Use a different body area each time you give yourself a shot. Keep track of where you give each shot to make sure you rotate body areas. This will help prevent skin problems from the injections. Do not inject into skin areas that are tender, red, bruised, or hard.

This medicine comes with a patient information leaflet and patient instructions. Read and follow these instructions carefully. Ask your doctor if you have any questions.

This medicine is available in two forms: a prefilled syringe or a prefilled pen, which you can use at home.

Check the liquid in the prefilled syringe. It should be clear and colorless to slightly yellow or slightly brown. Do not use it if it is cloudy, discolored, or has particles in it. Do not shake.

Allow the medicine to warm to room temperature for at least 30 minutes before you use it. Do not warm it in any other way.

Do not remove the needle cap from the prefilled syringe until you are ready to use it.

You might not use all of the medicine in each prefilled syringe or pen. Use each prefilled syringe and pen only one time. Do not save an open syringe or pen.
