2. Description:

No one knows exactly how paracetamol (4-acetamidophenol) works, but scientists think that it works mainly in the central nervous system (the brain and the spine). Paracetamol is thought to reduce the intensity of pain signals to the brain. It may also prevent the release of substances that increase pain and body temperature called prostaglandins.

Paracetamol is well tolerated at low doses, and is a common over-the-counter pain reliever.

3. What Is Paracetamol Used for?

At over-the-counter doses, paracetamol is commonly used to provide temporary relief of pain and discomfort associated with:

  • Headaches (e.g. migraines, tension headaches)
  • Muscle pain (e.g. strains and sprains, sport injuries)
  • Backache
  • Toothache
  • Muscle ache
  • Arthritis (including osteoarthritis)
  • Cold and flu symptoms
  • Fever

5. What Happens If I Miss A Dose?

Since paracetamol is often used only when needed, you may not be on a dosing schedule. If you are using the medication regularly, use the missed dose as soon as you remember. If it is almost time for your next regularly scheduled dose, skip the missed dose and use your next dose as directed. Do not use extra medicine to make up for a missed dose.

6. What Happens If I overdose?

Seek emergency medical attention if you think you have used too much of this medicine.

The first signs of an paracetamol overdose include loss of appetite, nausea, vomiting, stomach pain, sweating, and confusion or weakness. Later symptoms may include pain in your upper stomach, dark urine, and yellowing of your skin or the whites of your eyes.
