The doctor may also decide to run other liver tests, some of
these may be images of your liver and others may need a
small sample of tissue taken from the liver in order to examine
it more closely. Your doctor may also check to see if you have
tuberculosis and they may X-ray your chest or perform a lung
function test.
During the treatment:
Your doctor may perform the following examinations:
-
examination of the oral cavity and the pharynx for changes
in the mucous membrane such as inflammation or ulceration
-
blood tests/ blood count with number of blood cells and
measurement of serum methotrexate levels
-
blood test to monitor liver function
-
imaging tests to monitor liver condition
-
small sample of tissue taken from the liver in order to
examine it more closely
-
blood test to monitor kidney function
-
respiratory tract monitoring and, if necessary, lung function
test
It is very important that you appear for these scheduled
examinations.
If the results of any of these tests are conspicuous, your doctor
will adjust your treatment accordingly.
Elderly patients
Elderly patients under treatment with methotrexate should be
monitored closely by a physician so that possible side effects
can be detected as early as possible. Age-related impairment
of liver and kidney function as well as low body reserves of the
vitamin folic acid in old age require a relatively low dosage of
methotrexate.
