Unithiol (Dimercaptopropane sulfonate (DMPS)) — Uses, Dosage, Side Effects & Safety

Drug class: Chelating Agent

Overview

Unithiol (dimercaptopropane sulfonate, or DMPS) is a medication used to treat poisoning by heavy metals such as mercury, arsenic, and lead. It works by binding to these toxic metals in the body, forming complexes that are then excreted in the urine, helping to remove the metals from your system. Unithiol is often used in emergency settings for acute poisoning, but may also be prescribed for chronic exposure in certain cases. It is available as an injection or in oral form, depending on the severity of the poisoning and the patient’s needs. Key points for patients: Unithiol should only be used under medical supervision. It is important to follow your healthcare provider’s instructions carefully, as improper use can lead to side effects or reduced effectiveness. Always inform your doctor of any allergies or other medications you are taking.
