Iobenguane I 123 is a radiopharmaceutical. Radiopharmaceuticals are radioactive agents, which may be used to find and treat certain diseases or to study the function of the body's organs.

Iobenguane I 123 is used to find certain kinds of cancer of the adrenal glands (eg, pheochromocytoma, neuroblastoma). When very small doses of iobenguane I 123 are given, the radioactivity taken up by the adrenal gland helps find tumors of the adrenal glands. An image of the gland on film or on a computer screen can be provided to help with the diagnosis.

Iobenguane I 123 is also used during a test for patients with congestive heart failure. This may help the doctor see certain heart problems.

Iobenguane i 123 is to be given only by or under the direct supervision of a doctor with specialized training in nuclear medicine.

Skyla contains levonorgestrel, a female hormone that can cause changes in your cervical mucus and uterine lining, making it harder for sperm to reach the uterus and harder for a fertilized egg to attach to the uterus.

Skyla intrauterine device (IUD) is a small, flexible plastic T-shaped device. This device is placed in the uterus where it slowly releases the hormone to prevent pregnancy for 3 years. (Other types of levonorgestrel intrauterine systems release different amounts of hormone and are used for different lengths of time.)

Skyla can be used whether you have had children or not. It should not be used during pregnancy.

Levonorgestrel is a progestin hormone and does not contain estrogen. The Skyla IUD releases levonorgestrel in the uterus, but only small amounts of the hormone reach the bloodstream. Skyla should not be used as emergency birth control.
