Analysis of Unusual Adverse Effects After Radium-223 Dichloride Administration

Abstract

Background: To our knowledge, no previous study or literature review has been performed about the effects of the extravasation of therapeutic radiopharmaceutical agents and its potential consequences, especially regarding alpha-particle emitting radiopharmaceuticals.

Methods: Even if Radium-223 dichloride is known to be a relatively safe drug to manage, despite the correctness of the procedures applied , unexpected delayed adverse effects can occur. In our vast experience, we rarely observed lymphedema, even after some time, at the site of administration.

Results: Management of lymphedema caused by radiopharmaceuticals administration has been addressed through clinical examples. The sudden intervention allowed a fast remission of the signs and symptoms complained by patients treated with Radium-223 dichloride.

Conclusion: The management of adverse effects after radiopharmaceuticals administration as in case of lymphedema onset, is extremely simple. These data confirm the safety of Radium-223 treatment.
