Can Paracetamol Cause Kidney Damage?


When taken at recommended doses, paracetamol (also known as acetaminophen) is generally considered safe for most people and is one of the most commonly used pain relievers worldwide. However, excessive or prolonged use of paracetamol can potentially lead to adverse effects, including kidney damage.

The primary concern with paracetamol and kidney damage arises from overdose situations or chronic, long-term use of high doses beyond the recommended limits. Overdosing on paracetamol can result in liver damage, which, in severe cases, might lead to kidney problems as well. The liver metabolizes paracetamol, and if an overdose overwhelms the liver’s ability to process it, toxic byproducts can build up and cause harm to both the liver and potentially the kidneys.

Chronic use of high doses of paracetamol over a prolonged period may also have an impact on kidney function. Studies have suggested that long-term, high-dose usage of paracetamol might contribute to kidney damage, especially in individuals with pre-existing kidney conditions or risk factors such as dehydration.

For most people using paracetamol at recommended doses for short-term pain relief or fever reduction, the risk of kidney damage is extremely low. However, it’s crucial to adhere to recommended dosage guidelines and avoid exceeding the maximum daily limit (usually around 4,000 milligrams per day for adults) to minimize the risk of adverse effects.

Individuals with pre-existing kidney conditions, liver disease, or those taking medications that can affect the kidneys should consult a healthcare professional before using paracetamol or any other over-the-counter medications to ensure safety and appropriate dosing.

If you suspect an overdose or experience symptoms such as severe abdominal pain, yellowing of the skin or eyes, dark urine, or decreased urination after taking paracetamol, seek immediate medical attention or contact a poison control center. Prompt treatment is crucial in case of an overdose to prevent potential organ damage.
