Paracetamol: Uses, Dosage, Side Effects, and FAQs

 

Paracetamol, also known as acetaminophen, is one of the most widely used over-the-counter (OTC) medications for pain relief and fever reduction. It is popular due to its effectiveness, availability, and relatively mild side effect profile when used appropriately.

What Is Paracetamol?

Paracetamol belongs to the class of analgesics (painkillers) and antipyretics (fever reducers). It is often used to treat mild to moderate pain, such as headaches, muscle aches, menstrual cramps, toothaches, and joint pain. Unlike nonsteroidal anti-inflammatory drugs (NSAIDs) like ibuprofen, paracetamol has minimal anti-inflammatory effects, making it suitable for people who cannot tolerate NSAIDs.

How Paracetamol Works

Paracetamol works by inhibiting the production of certain chemicals in the brain and spinal cord called prostaglandins. These chemicals are involved in transmitting pain signals and regulating body temperature. By reducing prostaglandin levels, paracetamol alleviates pain and lowers fever.
