Postherpetic neuralgia
Supplements studied for postherpetic neuralgia.
Overview
Vitamin B12 (DEX Score 64; medium effect size, medium evidence, high trust) has medium-strength evidence for postherpetic neuralgia across three studies. Subcutaneous B12 injections about six times weekly for one month reduced shingles-related nerve pain better than oral B12 or lidocaine alone; combined with lidocaine, injections reduced pain by more than half when started early and improved rash, itching, and numbness.
Oral B12 alone was less effective than injections. See the heatmap and evidence reviews below.
