- Use：
- Methamidophos is highly toxic to mammals. Inhalation of methamidophos causing weakness, tightness in the chest, wheezing, headache, blurred vision, pinpoint pupils, tearing,and runny nose are common early symptoms. On accidental ingestion and with severe poisoning, methamidiophos causes nausea, vomiting, diarrhea, and cramps, sweating and twitching, weakness, shakiness, blurred vision, pinpoint pupils, dyspnea (shortness of breath), tightness in the chest, sweating, confusion, changes in heart rate, convulsions, coma, respiratory failure, and death. People with health disorders, such as high blood pressure, problems of the gastrointestinal, heart, liver, lung, or nervous system, have been reported to be more sensitive to methamidophos-induced toxicity. Reports have indicated that occupational workers exposed to methamidophos who developed poisoning with symptoms such as pain (needle type) in the feet, legs, and hands, high blood pressure, gastrointestinal disorders, heart, liver, lung, or nervous system problems, may be more sensitive to methamidophos.
