Is Tylenol Bad for the Kidneys?

Tylenol is an analgesic (pain reliever) commonly used by people who cannot use aspirin or ibuprofen. The generic name for Tylenol is acetaminophen. Other analgesics include ibuprofen and aspirin. When used properly, there is no evidence that Tylenol harms the kidneys.

  1. Significance

    • Continuously taking analgesics such as Tylenol and ibuprofen every day may result in kidney damage. The estimated risk for kidney damage from Tylenol and other analgesics is low--about four out of 100,000 people, according to the National Kidney and Urologic Diseases Clearinghouse.

    Risk Factors

    • People with kidney or liver disorders are at higher risk for kidney damage from Tylenol and should not take Tylenol without their doctor's approval. Overdose is also a risk factor. Symptoms of overdose can include jaundice (yellowing of eyes and skin), vomiting, kidney failure, loss of appetite, nausea, sweating, low blood pressure and changes in heart rhythms.

    Considerations

    • Other medications (both prescription and over-the-counter) may contain acetaminophen, check for the active ingredients on the label. Pay attention to labels that state "children's pain reliever," infants' pain reliever," or "aspirin-free."

    Long-Term Use

    • Some people must take Tylenol every day. They should have their doctors perform tests to ensure that their kidneys and liver are not harmed. The frequency of these tests should be determined by a doctor.

    Dosage

    • Unless your doctor directs you, do not take acetaminophen for more than 10 days in a row (five days for children). Do not take more than 4 grams of acetaminophen in a 24-hour period.
