What is PACT?

PACT is an abbreviation and a scientific term that stands for Photodynamic Antimicrobial Therapy. With this method, bacteria, viruses and fungi can be killed off effectively and without pain on skin surfaces and nails.

How does it work?

Microorganisms including fungus, bacteria and viruses all possess a cell wall, whereas typical human cells only have a cell membrane. Upon application of the PACT Fungal Nail Gel, the dye selectively targets the fungal cell walls making them sensitive to light.

The fungal cells can then be destroyed upon exposure to light, of a specific wavelength. This results in a chemical reaction that kills the required cells without harming the good healthy tissue.

How many treatments?

This is ultimately determined by your Podiatrist, taking into account the length of time that you have had the infection as well as the severity.

A typical treatment plan is

  • Mechanical debridement of the affected nail
  • Application of photosensitising gel
  • Application of the light source for 9.5 mins
  • The treatment should take approximately 30 mins
  • Repeated applications 3 x in one week
  • Review after 3 months

Tips to prevent reinfection include

  • Thoroughly dry feet after bathing
  • Apply a topical antifungal solution daily
  • Rotate shoes regularly to allow them to air and dry
  • Apply an antifungal powder or spray to rid shoes of fungus
  • Wash hosiery in hot water and even apply an antifungal solution to the washing cycle
  • Wear thongs in public showers and swimming centres
  • Wear socks that contain silver
  • Disinfect shower
  • Minimise micro trauma to the nails (which makes you more susceptible to infection) by ensuring correct shoe fit
  • Don’t share nail clippers
