Nerve 12 Tablet is not a pain relief medication. It contains vitamin B12 and is primarily used to manage nerve-related conditions such as neuropathy caused by vitamin B12 deficiency or nerve damage. It does not provide direct relief from wrist or joint pain, which may result from causes like strain, inflammation, arthritis, or injury. To ensure appropriate treatment, it is best to consult a doctor who can identify the underlying cause and recommend suitable pain relief or therapy.

Methylcobalamin (vitamin B12) is generally safe and does not usually interact with malaria medications or commonly used diabetes or blood pressure medicines. The usual adult dose is one tablet daily, but the exact dose may vary based on individual needs. Since the person has diabetes and high blood pressure, it is essential to take Methylcobalamin only if advised by a doctor, who can consider current medications, health status, and other factors to ensure it is safe and appropriate.
