Types of Peripheral Neuropathy - Toxic/Secondary to Drugs

 
Toxins

Toxins, poisons and chemicals can cause peripheral neuropathy. This can happen through drug or chemical abuse or through exposure to industrial chemicals in the workplace or in the environment (after either limited or long-term exposure). Common causes include: exposure to lead, mercury, arsenic and thalium. Some organic insecticides and solvents can result in neuropathies. Sniffing glue or other toxic compounds can also cause peripheral neuropathy. Certain herbal medicines, especially Chinese herbal medicines, are particularly rich in mercury and arsenic and taking them can lead to peripheral neuropathy.

Because patients may have subtle pain or weakness, it may be difficult to arrive at a specific diagnosis of toxic neuropathy.
