Typical symptoms of liver disease may include nausea, lack of appetite, discomfort on the right upper corner of the abdomen, generalized itching, dark urine and jaundice yellow discoloration of the eyes and skin , but many people have no symptoms at all.
Blood tests can usually detect evidence of liver damage before symptoms develop. When a medication known to possibly cause liver damage is used, your physician may recommend that blood tests be checked periodically after starting the medication so that any evidence of liver damage can be detected before symptoms appear.
Liver damage of any type is usually detected by doing blood tests. Usually there is no need to monitor the liver tests when a medication is started. If your physician is planning on using a medication that in the past has been shown to rarely cause liver damage, the most common test used to monitor the liver is a liver panel, which consists of several blood tests that detect liver damage. There are many other causes for elevated liver tests.
For that reason your physician may obtain a baseline liver panel prior to starting a medication to be sure that it is normal. Minor elevations of these tests may occur after starting a medication and do not indicate significant liver damage. Generally speaking physicians are most concerned about serious medication-induced liver damage when the levels of AST and ALT rise 3 to 5 times or more over baseline or if there is an increase in bilirubin.
If the elevations are minor, the medication is continued and the liver tests monitored. In most cases, the liver tests will return to normal despite continuing the medication. This medication is widely available without prescription and is present in many of the cold and flu remedies sold in drugstores as well as in prescription pain medications.
Acetaminophen, when used as directed, is extremely safe even for people with liver disease. However, taking too much acetaminophen at once, or taking a high dose of acetaminophen continuously over several days can cause damage to the liver. Healthy individuals should not take more than 1, mg of acetaminophen per dose, and should not take more than 4,mg in one day i.
In addition, even healthy persons should avoid taking 3,mg of acetaminophen daily for more than 3 to 5 days. Patients with liver disease should restrict the daily amount of acetaminophen to 2,mg per day, or even less if severe liver disease is present. Even if you have no liver disease, always use the smallest amount of acetaminophen needed to obtain relief.
