Painkiller warning: Overuse is known to cause serious inflammation of the liver – signs

When you follow the instructions on painkillers and other pill-bottle labels, it’s helpful and safe, and it generally doesn’t upset the stomach or liver. But if you take too much and in extreme cases, it can cause liver failure or toxic hepatitis.

Toxic hepatitis is an inflammation of your liver in reaction to certain substances to which you’re exposed.

The condition can be caused by alcohol, chemicals, drugs or nutritional supplements.

The symptoms of toxic hepatitis often go away when exposed to the toxin stops.

But toxic hepatitis can permanently damage your liver, leading to irreversible scarring of liver tissue (cirrhosis) and in some cases liver failure, which can be life-threatening.

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.

But toxic hepatitis can permanently damage your liver, leading to irreversible scarring of liver tissue (cirrhosis) and in some cases liver failure, which can be life-threatening.

Acetaminophen is the major metabolite of acetanilid and phenacetin, which were once commonly used drugs, and is responsible for their analgesic (pain-relieving) effects.

According to Mayo Clinic, symptoms of toxic hepatitis include:

• Yellowing of the skin and whites of the eyes (jaundice)
• Itching
• Abdominal pain in the upper right portion of the abdomen
• Fatigue
• Loss of appetite
• Nausea and vomiting
• Rash
• Fever
• Weight loss
• Dark or tea-coloured urine.
