What do toxins do to the liver?
The liver may be injured or damaged by many different substances or toxins including medicines, herbal and dietary supplements and chemicals.
The liver is responsible for clearing toxins away. So if you are exposed to high levels of a toxin, your liver can get damaged.
Toxins can inflame the liver (hepatitis) causing liver damage, or cause sudden massive death of liver cells resulting in acute liver failure.
The liver is very good at repairing itself. But if it is constantly exposed to a toxin, serious damage can happen. Eventually, exposure to toxins can lead to liver failure or even death.
What substances are toxic to the liver?
There are lots of things that are toxic for the liver.
Many medicines can have a side-effect of liver injury. This may be predictable, or in some cases rare and unpredictable. So when you start a new medicine, your doctor may recommend that your liver tests are monitored for a while.
A decision to use any medicine should be a balance between the potential benefits and the potential risks. Always follow your doctor’s instructions when you take medicines. Make sure you tell all your doctors if you have liver disease, as some medicines may be especially toxic for the liver.
Taking more than the recommended dose of paracetamol or nonsteroidal anti-inflammatory drugs (like ibuprofen or naproxen) can cause liver damage.

Chemicals and solvents

Chemicals that are especially toxic for the liver include:

- Vinyl chloride (a chemical used to make plastics)
- Paraquat (a weedkiller)

Drinking more than the recommended amount of alcohol makes your liver work harder. You can get hepatitis (inflammation) of the liver from drinking alcohol over time or suddenly, after binge drinking.
