What is Acute pain?

Published November 19, 2019

Acute pain is a normal response to tissue injury, which starts suddenly and is usually short-lived1

Why do we experience Acute pain?

Pain is your body’s way of letting you know something is wrong. Sensory nerve cells, called ‘nociceptors’ respond to noxious stimuli, such as painful pressure, cuts, or extreme heat or cold, by sending messages to the brain in the form of electrical impulses2.

The brain evaluates these messages and responds with appropriate action to help protect us from further harm. This might come in the form of a reflexive movement, such as quickly pulling your hand away after touching a hot surface. The brain may also respond by signaling the release of chemicals that suppress pain and promote the process of healing2.

Acute pain management: How can I treat acute pain?

Acute pain may be managed with pain-relieving medicines. Paracetamol and ibuprofen are medicines available for pain management that can be purchased without a prescription and are available on their own or in combination

  • Paracetamol is primarily thought to relieve pain by blocking the ‘pain signals ’ in the central nervous system from reaching the brain. However its mechanism of action yet has to be fully determined. Paracetamol can be used to relieve fever and pain such as headache and backache3.
  • Ibuprofen is a non-steroidal anti-inflammatory drug (NSAID) which can reduce pain and swelling by blocking the release of chemicals that cause inflammation in the body.It can be used to manage pain and inflammation associated with musculoskeletal disorders2.

Mersynofen combines the strength of paracetamol and ibuprofen to provide dual-action pain relief in a single tablet. Each tablet contains 500mg of paracetamol and 200mg of ibuprofen4.

Mersynofen can be used for the temporary relief of acute pain and/or inflammation associated with:

  • Backache
  • Muscular Aches
  • Period Pain
  • Headache
  • Sore throat
  • Tennis Elbow
  • Tension headache
  • Mild osteoarthritis
  • Sinus pain
  • Toothache
  • Aches and pain associated with cold

Just one Mersynofen tablet can provide stronger pain relief than two 500mg tablets of regular Paracetamol5 and can last up to 8 hours. It’s also non-drowsy, making it suitable for any time of the day. Mersynofen is only available in pharmacies.

The recommended Mersynofen dosage for adults under 65 and children from 12 years is one tablet every 8 hours with water when necessary. Mersynofen is not recommended for adults 65 years of age and over or children under 12 years of age. Do not take more than 3 tablets in 24 hours.

For more information about Mersynofen, speak with your local pharmacist or call 1800 818 806.
