IV infusion of certain pain relief medications have been known to provide substantial pain relief in patients with various chronic pain conditions. Pain medications can be delivered using safe and effective methods.

Certain infusion therapies have been studied extensively, while others have little data to support their use but anecdotally they seem to help.

IV infusions we use for chronic pain management include:  

  • Ketamine infusion
  • Lignocaine infusion
  • Magnesium infusion

These are non-opioid infusions which provide pain relief as well as allow opioid medication reduction.


Ketamine was developed in the 1960s and to this day we are still discovering potential benefits of treatment with ketamine. Ketamine has many clinical uses in chronic pain like neuropathic pain, post herpetic neuralgia, nerve injury, complex regional pain syndrome (CRPS), fibromyalgia and even cancer pain.

In-patient ketamine infusions can be used in selected individuals to support pain management and provide pain relief as well as allow safe and rapid opioid medication reduction or switching.

We only use ketamine infusions for chronic pain in carefully selected patients. We do not use ketamine for depression treatment.

We recognise that your pain affects your ability to do the things that make you who you are. We manage the impact that pain has on your world.
