▪Treatments at the early stages
1. Detection of the route of methylmercury exposure and its exclusion
2. Promotion of methylmercury excretion
Administration of chelating agents: Chemical trapping of methylmercury
and excretion via urine
Administration of SH-compounds having high affinity for methylmercury:
oral administration of thiol resin in order to inhibit re-absorption of
methylmercury from intestines
Hemodialysis with a SH-compounds L-cysteine
3. Administration of antioxidants
It has been clarified one of the causes of methylmercury-induced cellular
damage is the increase in reactive oxygen species in tissue cells.
Researches are conducted on the use of antioxidants, e.g., vitamin E, which
eliminate reactive oxygen species, in addition to excretion treatment.
4. Treatment of symptoms
Drug therapy to control severe symptoms, e.g., convulsion
