Paracetamol Overdose
Paracetamol is like a staple medicine in many households. The cost of treatment is high for an average family so they rely on affordable care that can relieve their symptoms and help them carry on with their routine lifes.
Usually they don’t consider the side effects of the medicine but focus on the immediate issue. Sometimes when the symptoms are not reducing they increase the dosages voluntarily.
This is the major cause of the intentional paracetamol overdose.
Sometimes the medications people use are combinations of acetaminophen. When people use paracetamol over these medications, sometimes it may cause unintentional paracetamol overdoses.
Intentionally or unintentionally paracetamol overdoses can lead to liver damage or death.
Next time before you take your paracetamol, think about having a liver disease and liver damage due to an unnoticed problem.
