Who should not receive DaTscan?

People who are allergic to iodine should not receive DaTscan, a drug sometimes used in combination with brain scans to help doctors diagnose Parkinson's disease. If you're allergic to iodine and are given DaTscan, you could develop a rash, hives, swelling of the face and trouble breathing.

Women who are pregnant should receive DaTscan only if the benefits outweigh the risks. This drug emits radiation, which can harm unborn babies. At least one of the ingredients in DaTscan, iodine 123, can pass into breast milk and cause serious side effects in infants. Women who are breastfeeding should consider not nursing their babies for six days after receiving DaTscan, pumping and discarding their breast milk, to allow the drug to be cleared from their bodies.

People with kidney disease may take longer to eliminate DaTscan from their bodies, resulting in a higher dose of radiation. Talk with your doctor about these and any other medical conditions you have before receiving DaTscan.
