What is Mircera?

Mircera injection contains epoetin beta and methoxy polyethylene glycol. Epoetin beta and methoxy polyethylene glycol is a man-made form of a protein normally produced by the kidneys that helps your body produce red blood cells. When your body does not make enough of this protein because of kidney failure, you can develop a condition called anemia (lack of red blood cells).

Mircera is used to treat anemia (lack of red blood cells) and to reduce the need for blood cell transfusions.

Mircera is used to treat anemia caused by chronic kidney disease in adults, or in children at least 5 years old who are on hemodialysis.

This medicine is not for treating anemia caused by cancer chemotherapy. Epoetin beta and methoxy polyethylene glycol may increase tumor growth or decrease survival time in people with certain types of cancer.

Mircera should not be used to take the place of an emergency blood cell transfusion.

Warnings

You should not use Mircera Injection if you have uncontrolled high blood pressure or if you have ever had pure red cell aplasia.

Mircera is not for treating anemia caused by cancer chemotherapy.

How should I use Mircera?

Use Mircera exactly as it was prescribed for you. This medicine is usually given once every 2 weeks or once per month. Follow all directions on your prescription label and read all medication guides or instruction sheets. Your doctor may occasionally change your dose.

Mircera is injected under the skin or given as an infusion into a vein. When used in a child, the medicine should be given only into a vein. A healthcare provider will give your first dose and may teach you how to properly use the medication by yourself.

Read and carefully follow any Instructions for Use provided with your Mircera. Ask your doctor or pharmacist if you don't understand all instructions.

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

Your blood pressure will need to be checked often. You will also need frequent medical tests, and your next dose may be delayed based on the results.

Call your doctor if you have signs that your body is not responding to Mircera (pale skin, unusual tiredness, lack of energy, dizziness, fainting).

Your doctor may have you take an iron supplement. Take only the type and amount your doctor prescribes.

If you need surgery, tell your surgeon you currently use Mircera. You may need to take medicine to prevent blood clots for a short time after your surgery.

Store prefilled syringes in the refrigerator. Do not freeze or shake. Keep the medicine in the original container until you are ready to give an injection.

You may also store a prefilled syringe at cool room temperature up to 25°C (77°F), but you must use the syringe within 30 days or throw it away. Protect from light.

Each prefilled syringe is for one use only. Throw it away after one use, even if there is still medicine left inside.

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.
