Most people have no side effects after receiving DaTscan, a drug sometimes used in combination with brain scans to help doctors diagnose Parkinson's disease. However, some have reported headache, nausea, dry mouth or dizziness.

DaTscan contains iodine, so people who are allergic to that chemical can develop a rash, hives, swelling of the face and trouble breathing after receiving the drug. Your healthcare providers will watch you for these symptoms and treat you with corticosteroids and antihistamines if they appear. People who are allergic to iodine should not be given DaTscan. Tell your doctor before receiving DaTscan if you are allergic, or think you may be allergic, to iodine.
