The effectiveness of DMSA, side effects, and special attention

Dimercaptosuccinic acid, commonly known as DMSA, is a chelating agent that is used to remove heavy metals from the body. It has been primarily used for the treatment of heavy metal poisoning, most commonly lead poisoning. DMSA works by binding to heavy metals in the body, forming stable complexes that are then excreted through urine. Here’s some information on its effectiveness, side effects, and special attention:


DMSA has been found to be effective in treating lead poisoning, especially in cases of moderate to low lead exposure. It is often used in children who have been exposed to lead paint or other sources of lead contamination. DMSA can also be used for treating other heavy metal poisonings, such as mercury and arsenic, although its effectiveness may vary depending on the specific metal and the severity of poisoning.

Side Effects:

While DMSA is generally considered safe when used under medical supervision, it can have some side effects. Common side effects may include nausea, vomiting, abdominal pain, and diarrhea. These side effects are usually mild and temporary. In some cases, allergic reactions or skin rashes may occur. DMSA can also cause changes in blood counts, liver enzymes, and kidney function, so regular monitoring is important during treatment.

Special Attention:

Here are some points to consider when using DMSA:

  • Medical Supervision: DMSA should always be used under the supervision of a qualified medical professional, especially in cases of heavy metal poisoning. The dosage and duration of treatment need to be carefully determined based on the individual’s condition.
  • Children and Pregnancy: DMSA is often used in children for lead poisoning, but the dosages need to be adjusted based on the child’s weight and medical history. Pregnant or breastfeeding women should avoid DMSA unless the potential benefits clearly outweigh the risks.
  • Kidney Function: DMSA is excreted through the kidneys, so individuals with impaired kidney function may need dose adjustments or extra monitoring to prevent kidney damage.
  • Drug Interactions: DMSA can interact with other medications, so it’s important to inform your healthcare provider about any other drugs you’re taking.
  • Chelation Therapy: DMSA is just one form of chelation therapy. Other chelating agents, such as EDTA, can also be used for heavy metal removal. The choice of chelator depends on the specific metal and the individual’s medical condition.
  • Risk-Benefit Evaluation: The decision to use DMSA or any chelating agent should be based on a thorough assessment of the risks and benefits. It’s important to weigh the potential benefits of removing heavy metals against the possible side effects of the treatment.
