What MYOVIEW is used for
MYOVIEW is used in the preparation of Technetium [99mTc] Tetrofosmin Injection, a radioactive medicinal product. Such substances are also known as radiopharmaceuticals.
Such radiopharmaceuticals are given in small amounts to find or rule out a disease. When used in this way the radiation your body receives is very low and is considered safe.
After the radioactive liquid is given to you, it is taken up by the organs of interest, especially the heart muscle or just passes through your body. The radiation is taken up by a special camera and pictures are prepared. These pictures allow the nuclear medicine doctor to detect any problems.
MYOVIEW is used to help detect areas in the heart that may not be getting enough blood to work properly.
MYOVIEW is used as an aid in diagnosis only. It is not used to treat or cure the condition.

How MYOVIEW is given
Your doctor may have special instructions for you to follow to get ready for your procedure. You should not eat the night before or have only a light breakfast on the morning of your test.
MYOVIEW is given as an injection into a vein. MYOVIEW must only be given by a doctor or nurse.
Your doctor will decide what dose of MYOVIEW you will receive.
MYOVIEW is usually given in two doses, one during exercise (or after you have got medicine to increase your heart rate) and one at rest about 4 hours after the first dose. Soon after it is given diagnostic images will be taken.
If you have any questions about taking MYOVIEW or about the diagnostic procedure, ask your doctor.
After being given MYOVIEW
MYOVIEW breaks down quickly after it is given and is largely removed from the body after about 48 hours.
There are usually no special precautions to observe for radiopharmaceuticals like MYOVIEW because they are used in small amounts for diagnosis.
If you have any questions or concerns, be sure to discuss these with your doctor or pharmacist.
