Hepatic dysfunction, including jaundice, hepatic cholestasis, and acute cytolytic hepatitis, have been reported. A positive dechallenge is a 50% fall in serum aminotransferase levels within 8 days of stopping the drug. A positive dechallenge is very helpful in cases of use of multiple medications. Drugs that result in massive necrosis are propylthiouracil, INH, phenytoin, phenelzine, sertraline, naproxen, diclofenac, kava kava, and ecstasy. The only specific treatment for most cases of liver damage caused by taking a medicine is to stop taking the medicine that caused the problem.
- Your liver acts as your body’s primary chemical processing plant, handling approximately 90% of all medications you take.
- Dietary supplements including herbal products are not being regulated as similar as prescribed medications or over-the-counter drugs.
- Certain medications are particularly known for their effects on liver function.
- Emergency liver transplantation has utility in the setting of drug-induced fulminant hepatic injury.
- If levels aren’t in the normal range, it could be a sign of liver hepatotoxicity.
- In the case of acetaminophen, alcohol use leads to accumulation of a toxic byproduct of acetaminophen in the liver that can kill the liver cells.
How can I test my liver function at home?
For that reason, whenever possible, physicians prefer to use “liver-safe” medications when we know a person has liver disease. Despite being “natural” but some ingredients can be toxic to the liver. Medications Affecting Liver “Dietary include herbal supplements can be sold with little testing, no proof of efficacy, and no safety guarantee. Dietary supplements including herbal products are not being regulated as similar as prescribed medications or over-the-counter drugs. Patients with liver disease should restrict the daily amount of acetaminophen to 2,000 mg per day, or even less if severe liver disease is present.
How Do You Know If Your Liver Is Damaged From Medicine?
Serum ALT may rise and fall quite rapidly, and waiting a week or two before obtaining confirmation of elevations may lead to a false conclusion that the initially observed abnormality was spurious. Of greater concern, delay in retesting may allow progression to severe worsening if the initial abnormality was the herald of a severe reaction to follow. The need for prompt repeat testing is especially great if the ALT is much greater than three times the upper limit of normal or total bilirubin level is greater than two times the upper limit of normal.
What Drugs Cause Liver Damage?
- Key biomarkers include ALT (alanine aminotransferase) and AST (aspartate aminotransferase), which elevate when liver cells are damaged.
- If you are concerned about any of the data in your dashboard please consult your physician immediately.
- Taking multiple medications simultaneously can significantly increase liver stress through various mechanisms.
- Knowing whether the patient was exposed to the same drug before may be helpful.
The cause of idiosyncratic DILI is a combination of risk factors that relate to the drug, the individual, and the environment. Also according to the AASLD guidelines, all patients who present within 4 hours of a single–time-point acetaminophen overdose should receive gastric lavage and activated charcoal. Hepatotoxicity from acetaminophen is due to the toxic metabolite NAPQI. Alcohol and other drugs induce cytochrome P-450-2E1 and may result in enhanced toxicity. They involve conjugation with a moiety (ie, acetate, amino acid, sulfate, glutathione, glucuronic acid) that further increases solubility. Subsequently, drugs with high molecular weight may be excreted in bile, while the kidneys excrete the smaller molecules.
What Causes Hepatotoxicity?
It includes some of the most common prescription and over-the-counter (OTC) drugs that can cause liver damage. If you’re not sure if a medication or supplement is safe to use or use with other medications you’re taking, talk to your healthcare provider. Work closely with your healthcare provider to find the right balance between therapeutic benefit and liver safety. Don’t discontinue medications without medical guidance, as abrupt cessation can sometimes be more dangerous than continued use. Instead, focus on regular monitoring, supporting your liver through healthy lifestyle choices, and maintaining open communication about any concerns or symptoms you experience. With the right approach, you can protect your liver health while still receiving the medications you need for optimal wellness.
Individual Factors That Increase Liver Sensitivity
Lock up all drugs or chemicals in your home so children don’t eat them. They are more at risk of liver toxicity because of their small size. The exact amounts of alcohol and acetaminophen that can lead to liver damage aren’t known. High PT levels could mean liver damage, but certain blood thinners can also cause it to be elevated. If you notice any of the symptoms and have any of the things that can raise your odds of having toxic liver disease, see your doctor right away.
For those taking potentially hepatotoxic medications long-term, establishing baseline liver values before starting treatment and monitoring regularly helps detect problems early. If you’re interested in comprehensive liver health monitoring, regular testing can provide peace of mind and early detection of any issues. Taking proactive steps to support your liver health can minimize medication-related stress and reduce your risk of drug-induced liver injury.

Drugs that lead to a pure cholestatic reaction include anabolic steroids (eg, methyl testosterone, oxymetholone, fluoxymesterone) and contraceptive steroids. Drugs that can cause cholestatic hepatitis include erythromycin, azithromycin, ciprofloxacin, ofloxacin, ranitidine, cimetidine, phenytoin, gold salts, and terbinafine. Intrahepatic cholestasis may be accompanied by acute cholangitis and is observed in patients taking chlorpromazine, allopurinol, chlorpropamide, and hydralazine.
Maintaining a healthy weight reduces fatty liver disease risk, which can compromise drug metabolism. Regular exercise improves liver blood flow and helps maintain healthy enzyme levels. Amiodarone 20, 21, 22, 23, 24 causes abnormal liver function test results in 15-50% of patients. The spectrum of liver injury is wide, ranging from isolated asymptomatic aminotransferase elevations to a fulminant disorder. Hepatotoxicity usually develops more than 1 year after starting therapy, but it can occur in 1 month.
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. People with known liver disease may be at increased risk of liver injury when certain medications are used. That means that your provider has to rule out other causes of liver disease before diagnosing you with drug-induced liver damage. Remember that medication-induced liver effects vary greatly among individuals due to genetics, existing health conditions, and lifestyle factors. What causes significant liver enzyme elevation in one person might have minimal impact on another.
13 Alkaline phosphatase and bilirubin levels were rarely elevated, and severe injury was rare. Indications were that rechallenging a patient with this medication could be appropriate, and in more than 80% of cases, the alanine aminotransferase (ALT) abnormalities resolved or did not reoccur. Hepatotoxicity is a known characteristic of over 1000 medications and herbal compounds, 1, 2 with drugs accounting for 20-40% of all instances of fulminant hepatic failure.
Ultrasonography is effective to evaluate the gall bladder, bile ducts, and hepatic tumors. Imaging studies are used to exclude causes of liver pathology, after which a diagnosis can be made. Performing laboratory tests to assess and diagnose the effects of the suspected medication is essential. Massive necrosis is an extension of submassive necrosis and manifests as fulminant failure. If the clinician is not familiar with the drug or if any question remains about the safety of continuing a drug, consultation with a hepatologist should be considered.

Learn why kidney issues cause excessive thirst, including causes like chronic kidney disease, diabetes insipidus, and electrolyte imbalances, plus treatment options. Currently, no specific tests are available for diagnosing DILI, so doctors may use different diagnostic criteria when confirming the condition. The primary cause of DILI is whichever drug has injured the liver, but the process varies depending on whether the condition is intrinsic or idiosyncratic. As a result, it is the area that the toxins within drugs most affect.
Not everyone experiences the same liver effects from medications. Several individual factors can make your liver more sensitive to drug-induced stress or damage.
