The liver is the principal organ that is capable of converting
drugs into forms that can be readily eliminated from the body. Given
the diversity in use today and the complex burden they impose upon
the liver, it is not surprising that a broad spectrum of adverse
drug's effects on liver functions and structures has been documented.
The reactions range from mild and transient changes in the results
of liver function tests to complete liver failure with death of
the host. Many drugs may affect the liver adversely in more than
one way, as cited below in several listings. The use of the following
drugs requires careful monitoring of their effects on the liver
during the entire course of treatment.
This list is just a general guideline. Many drugs affect the liver
to one degree or another and we can't list all of them here; new
drugs are always being approved for general use. Read the accompanying
literature with your prescriptions and always consult with your
doctor or pharmacist about any new medication if you have liver
disease!
