Meta-analysis confirms B12 reduces shingles nerve pain
Researchers analyzed four randomized controlled trials involving 383 participants to determine whether vitamin B12 could help relieve postherpetic neuralgia (PHN)—the painful nerve condition that sometimes follows shingles. The results were encouraging: patients receiving B12 experienced significantly greater pain reduction compared to those taking placebo, with improvements also seen in quality of life and reduced need for pain medications.

While these findings suggest B12 could serve as a valuable complementary treatment for PHN, the researchers emphasized that more research is needed before making definitive clinical recommendations.

Local B12 injections reduce shingles pain
We conducted a clinical trial to determine how effective local injections of vitamin B12, specifically methylcobalamin, combined with lidocaine, are in treating pain caused by shingles, known as subacute ophthalmic herpetic neuralgia (SOHN). One hundred and five patients participated, each experiencing moderate to severe pain. They were divided into three groups to receive different treatments: a local injection of methylcobalamin and lidocaine, an intramuscular injection of methylcobalamin with local lidocaine, or oral methylcobalamin alongside local lidocaine.

Throughout the four-week trial, we observed significant pain relief among all groups, but the local injection group reported the most substantial reduction in pain. For example, their pain scores dropped from an average of 6.7 to 2.8, while the other groups showed less improvement. Additionally, most people receiving local injections experienced a clinically meaningful reduction in pain, which wasn't as pronounced in the other treatment groups.

Those in the local injection group also reported significantly less need for pain relief medication by the end of the study, signaling a potential improvement in their overall quality of life while undergoing treatment. Overall, our findings suggest that local methylcobalamin injections, when used with lidocaine, might provide superior pain relief compared to systemic or oral options in patients suffering from shingles-related pain.

Methylcobalamin injections relieve shingles pain
We conducted a study to see how effective local injections of methylcobalamin, a form of vitamin B12, could be in easing pain and enhancing quality of life for people suffering from subacute herpetic neuralgia, a painful condition related to shingles.

Ninety-eight participants over the age of 50, all experiencing significant pain after a shingles rash, were involved in this randomized controlled trial. They received either local methylcobalamin injections, oral methylcobalamin, or lidocaine injections over a four-week period, and we measured various pain levels and quality of life indicators pre- and post-treatment.

The results showed that local methylcobalamin injections significantly reduced overall pain and other pain-related symptoms compared to the other groups. Notably, many participants reported a marked improvement in their daily living activities and overall quality of life. However, it is important to note that oral methylcobalamin did not lead to significant pain relief, which highlights the advantage of local injections over oral treatments in this case.

Overall, we observed that local methylcobalamin injections appear to be an effective and well-tolerated option for treating pain associated with shingles.

Vitamin B12 reduces shingles pain
We investigated the effects of a combination of vitamin B12 (methylcobalamin) and lidocaine on acute ophthalmic herpetic neuralgia, commonly known as shingles. The study involved 98 patients who were divided into two groups based on when their shingles symptoms began—those with symptoms for three days or less and those between four to seven days. Each group was further split into a control group receiving standard treatments and a treatment group receiving the combination therapy locally for a duration of 14 days.

Our findings revealed that the combination treatment significantly reduced pain and improved healing compared to the control group. Specifically, patients who received the methylcobalamin and lidocaine mixture experienced faster healing of skin rashes and marked reductions in pain levels. Notably, the incidence of postherpetic neuralgia (PHN), a common complication after shingles, was also much lower in those receiving the combination treatment, reaching just 2.04% at three months.

This suggests that using vitamin B12 along with lidocaine could be a promising therapeutic option for people suffering from shingles, particularly if applied within the first week of symptom onset. The results highlight not just the treatment’s efficacy in relieving pain but also its potential to enhance overall recovery from this challenging condition.

B vitamins effectively treat shingles symptoms locally
Eighty patients with severe shingles-related itching received four weeks of locally injected treatments in a controlled trial comparing thiamine (B1), cobalamin (B12), lidocaine, or a B1-B12 combination. Thiamine significantly relieved itching, while cobalamin effectively reduced pain, with the combination delivering both benefits.

Within just seven days, all three vitamin treatments showed meaningful relief—thiamine helped 16 patients achieve 30% or greater itch reduction, cobalamin helped 18 patients with pain relief, and the combination benefited 18 with itch reduction and 19 with pain reduction. Importantly, the treatments also improved daily functioning and quality of life. The approach proved tolerable and safe, offering a promising alternative to traditional pain-relieving drugs like lidocaine.
