Neuropathic Pain Medications (gabapentinoids, SNRIs, TCAs)

Neuropathic pain medications are used to help manage pain caused by nerve damage or irritation. Unlike typical painkillers, these medicines act on the nervous system to calm overactive or sensitised nerves. They are often used for conditions such as nerve injury, post-surgical pain, or chronic pain syndromes. At Wessex Pain Clinic, your consultant will assess your symptoms carefully to select the most appropriate medication and dosage for your individual needs. We will also support you in medication rationalisation, looking for alternatives to long term medications. Many of these medications have significant side effects. We can help you make an informed decision as to what medications, if any, are right for you.

How the Procedure Works

Neuropathic pain arises when nerves themselves become damaged or dysfunctional, leading to abnormal pain signals. This can cause sensations such as burning, tingling, shooting, or electric-shock–like pain. Standard anti-inflammatory or opioid painkillers are often less effective in this type of pain, so specific nerve-targeting medicines are used instead.
There are three main groups of medications commonly prescribed:

Gabapentinoids (Gabapentin, Pregabalin):
These medicines reduce the excitability of nerve cells, helping to calm abnormal firing and decrease pain signalling. They are usually started at a low dose and gradually increased to achieve benefit while minimising side effects.

Serotonin and Noradrenaline Reuptake Inhibitors (SNRIs – Duloxetine, Venlafaxine):
These antidepressant-type medicines increase the levels of natural neurotransmitters that help regulate pain pathways in the brain and spinal cord. They can also improve sleep and mood, which often enhances overall pain control.

Tricyclic Antidepressants (TCAs – Amitriptyline, Nortriptyline):
TCAs have been used for many years in pain management. In low doses, they can help reduce pain transmission and improve sleep without acting primarily as antidepressants.

Your consultant will explain which option (or combination) is most suitable, considering your general health, other medications, and potential side effects. We may suggest a reduction on what you are currently taking if you are not seeing benefit, or are experiencing side effects. We will contact your GP (with your consent) to enable coordinated care.

What Conditions It Can Help With

Neuropathic pain medications may be used for:
Nerve injury or nerve entrapment

Post-surgical or post-traumatic nerve pain
Complex Regional Pain Syndrome (CRPS)
Post-herpetic neuralgia (after shingles)

Aimed Benefits

The aim of treatment is to reduce nerve-related pain, burning, and sensitivity, and to improve function, sleep, and overall quality of life. However many people experience side effects with little benefit. We will work closely with you to rationalise the medications that you are taking, ensuring that your quality of life remains the overall indicator as to how effective a treatment is.

Risks and Considerations

All medications can cause side effects or interact with other drugs. Your consultant will discuss the options in detail and tailor the plan to your individual circumstances. You will always have the opportunity to ask questions before starting treatment or reducing treatment.

Combined Approach / Multidisciplinary Care

At Wessex Pain Clinic we find that the best results come from combining medical treatments with active rehabilitation. Medications are often most effective when paired with physiotherapy, movement-based exercise, and — where appropriate — psychological support. This comprehensive approach addresses both the physical and emotional aspects of pain and supports longer-term improvement.
