Downsides of chelation therapy consist of drug toxicity in a few patients and likewise the extensive utilization of suboptimal chelation protocols, resulting in ineffective therapies. Drug metabolic effects, and interactions with other metals, drugs and dietary molecules also affected iron chelation therapy. Drug collection and also the identification of successful or ideal dose protocols are essential for positive therapeutic outcomes in using chelating drugs in TM and various iron-loaded and non-iron-loaded ailments, together with typical iron toxicity. Keyword phrases: aspirin; drug efficacy; drug toxicity; iron chelation therapy; iron overload; neurodegenerative conditions; best dose protocols; pharmacology; thalassemia.
