June 15, The liver is a remarkable, if underappreciated, organ. It turns the nutrients in our diets to substances the body can use and converts toxins into harmless substances or makes sure they are removed from the body When the liver is working well, our metabolism hums along in equilibrium.
But drugs and dietary supplements can sometimes wreak havoc with that system, leading to dangerous liver problems. Our goal is to prevent the toxicity of drugs.
Data suggest that prescription and over-the-counter drugs OTC and dietary supplements cause more acute liver failure cases than all other reasons combined. FDA has identified several instances of liver damage caused by dietary supplements. For example, the agency has issued public health warnings and sent warning letters to companies marketing supplements for weight loss and muscle building.
In one instance, a Texas -based company agreed to recall and destroy certain dietary supplement products after discovering a link between the supplement and cases of liver failure and non-viral hepatitis.
No Easy Way to Identify the Vulnerable Finding even a few cases of serious liver toxicity in clinical trial subjects exposed to a drug can be a reason for discontinuing the trial. Also, cases of serious liver toxicity have prompted FDA to request sponsors to withdraw their approved drugs from the market.
Drugs that appear to be safe in pre-clinical studies still may be harmful to some patients. A few drugs are toxic to the liver only when used in excess.
One example is acetaminophen. Overdoses leading to serious liver injury have resulted from consumers inadvertently taking both OTC and prescription drugs containing acetaminophen. Inadvertent overdoses with prescription drugs that contain acetaminophen and a narcotic have been responsible for a significant proportion of all the cases of acetaminophen-related liver failure in the United States, some of which have resulted in liver transplant or death.
FDA has taken steps to keep consumers safe. In earlyFDA requested withdrawal of over applications for combination prescription acetaminophen drug products containing more than mg acetaminophen per dosage unit.
The agency also has reminded pharmacists and physicians to stop prescribing and dispensing combination prescription acetaminophen products containing more than mg.
Some antibiotics and nonsteroidal anti-inflammatory medications also have been tied to liver damage. Hepatitis, a liver inflammation, can have several potential causes. Drugs may induce a form of hepatitis that closely resembles viral hepatitis liver inflammation caused by viral infection. Signs and Symptoms How can you recognize the signs of liver problems?
Avigan says you might feel tired and have a poor appetite. In more extreme cases, your eyes and skin become yellowish jaundice and your skin becomes very itchy. When patients taking a drug they have not used before get those symptoms, they should seek immediate medical attention and stop using that drug if it is identified as the cause, Avigan cautions.
If the symptoms surface and the patient has been taking a medication for a long time, there could be another cause. Obesity and excessive consumption of alcohol also can damage the liver.
