Drug-induced liver injury
Toxic hepatitis; Drug-induced hepatitis
Drug-induced liver injury is an injury of the liver that may occur when you take certain medicines.
Other types of liver injury include:
- Viral hepatitis
- Alcoholic hepatitis
- Autoimmune hepatitis
- Iron overload
- Fatty liver
Causes
The liver helps the body break down certain medicines. These include some drugs that you buy over-the-counter or your health care provider prescribes for you. However, the process is slower in some people. This can make you more likely to get liver damage.
Some drugs can cause hepatitis with small doses, even if the liver breakdown system is normal. Large doses of many medicines can damage a normal liver.
Many different drugs can cause drug-induced hepatitis.
Painkillers and fever reducers that contain acetaminophen are a common cause of liver injury, particularly when taken in doses greater than those recommended. People who drink alcohol to excess are more likely to have this problem.
Nonsteroidal anti-inflammatory drugs (NSAIDs), such as ibuprofen, diclofenac, and naproxen, may also cause drug-induced hepatitis.
Other drugs that can lead to liver injury include:
- Amiodarone
- Anabolic steroids
- Birth control pills
- Chlorpromazine
- Erythromycin
- Halothane (a type of anesthesia)
- Methyldopa
- Isoniazid
- Methotrexate
- Statins
- Sulfa drugs
- Tetracyclines
- Amoxicillin-clavulanate
- Some anti-seizure medicines

Your provider will do a physical exam to check for an enlarged liver and abdominal tenderness in the right upper part of the belly area. A rash or fever may be part of some drug reactions that affect the liver.
Enlarged liver
Hepatomegaly is swelling of the liver beyond its normal size. If both the liver and spleen are enlarged, it is called hepatosplenomegaly.
Abdominal tenderness
Abdominal pain is pain that you feel anywhere between your chest and groin. This is often referred to as the stomach region or belly.
Treatment
The only specific treatment for most cases of liver damage caused by taking a drug is to stop the drug that caused the problem.
However, if you took high doses of acetaminophen , treatment should be started as soon as possible after you develop liver injury.
High doses of acetaminophen
Acetaminophen (Tylenol) is a pain medicine. Acetaminophen overdose occurs when someone accidentally or intentionally takes more than the normal or r...
If symptoms are severe, you should rest and avoid heavy exercise, alcohol, acetaminophen, and any other substances that might harm the liver. You may need to get fluids through a vein if nausea and vomiting are very bad.
Outlook (Prognosis)
Drug-induced liver injury most often goes away within days or weeks after you stop taking the drug that caused it.
Possible Complications
Rarely, drug-induced liver injury can lead to liver failure.
When to Contact a Medical Professional
Call your provider if:
- You develop symptoms of liver injury after you start taking a new medicine.
- You have been diagnosed with drug-induced liver injury and your symptoms do not get better after you stop taking the medicine.
- You develop any new symptoms.
Prevention
Never use more than the recommended dose of over-the-counter medicines containing acetaminophen (Tylenol).
DO NOT take these medicines if you drink heavily or regularly; talk to your provider about safe doses.
Always tell your provider about all the medicines you take, including over-the-counter drugs and herbal or supplemental preparations. This is very important if you have liver disease.
Talk to your provider about other medicines you may need to avoid. Your provider can tell you which medicines are safe for you.
