Neuropathic Pain & Compounding
Burning, shooting, tingling – why standard painkillers often fail and what options exist.
What Is Neuropathic Pain?
Pain caused by damage or dysfunction of the nervous system itself. Descriptors: burning, electric shocks, tingling, numbness, or stabbing. Unlike inflammatory or mechanical pain, it often persists after the initial injury heals.
Common Causes
- Diabetic peripheral neuropathy
- Post‑herpetic neuralgia (after shingles)
- Chemotherapy‑induced peripheral neuropathy
- Post‑surgical nerve damage
- Spinal radiculopathy (sciatica)
- Trigeminal neuralgia
- Complex regional pain syndrome (CRPS)
Standard First‑Line Treatments
- Gabapentinoids (gabapentin, pregabalin)
- SNRIs (duloxetine, venlafaxine)
- Tricyclic antidepressants (nortriptyline, amitriptyline)
- Topical lidocaine (patch or cream) for localised neuropathy
Many patients achieve meaningful relief. However, side effects (sedation, dizziness, weight gain) or incomplete response are common.
Where Compounded Medications Fit
1. Multimodal Topical Creams
For localised neuropathic pain (e.g., feet, hands, a single dermatome), compounded creams may combine a local anaesthetic (lidocaine), an NMDA antagonist (ketamine), a calcium channel modulator (gabapentin), and a tricyclic (amitriptyline). These target several neuropathic mechanisms simultaneously.
2. Low‑Dose Naltrexone (LDN)
LDN has shown benefit in fibromyalgia (which has a central neuropathic component) and some peripheral neuropathies. It is off‑label; discuss with your prescriber.
3. Custom‑Strength Oral Medications
For patients who need very low starting doses (e.g., 25 mg pregabalin when 75 mg capsules are the smallest commercial size) or slow tapering, compounding provides flexibility.
Realistic outcome: Even with optimal treatment, complete relief is rare. A 30–50% reduction in pain intensity is considered a good response. Combination approaches (oral + topical + physical therapy) often work better than any single therapy.
If you have neuropathic pain that isn't well‑controlled, ask your prescriber: "Could a compounded topical cream or LDN be appropriate for me? What evidence supports it for my specific condition?"
