What should I watch for while using this medicine?

This medicine should be given only under the supervision of a physician after assessing your medical condition. It is only effective to treat contamination with radioactive plutonium, americium, or curium. This drug does not help eliminate other forms of radiation from the body.

You will have regular check-ups to determine the level of radiation in your body. The amount of radiation in your body will determine how long you have to take this medicine.

To protect your kidneys, drink plenty of water or other fluids as directed and void frequently while you are taking this medicine.

You will be given instructions to reduce the chance of exposing others to radiation. For example, some radiation gets into the urine and stool. A toilet should be used instead of a urinal, and it should be flushed several times after each use. Spilled urine or stool should be cleaned up completely. Wash your hands thoroughly and often. If body fluids soil clothing, wash the clothes separately.

Parents and caregivers should take extra care in handling the urine, stool, and sputum of children to avoid any exposure.

Nursing mothers should take extra care in disposing of breast milk.
