A systematic review of the potential effects of medications and drugs of abuse on dopamine transporter imaging using [ 123 I]I-FP-CIT SPECT in routine practice.

Nevertheless, the decision to withdraw any medication must be made by the specialist in charge of the patient's care and considering the pros and cons of doing so.
