The main drugs that nourish the peripheral nerves are the B vitamins, for example, vitamin B11 tablets/dose, taken orally 3 times/day. Methylcobalamin is also known as vitamin B121 tablets/dose, taken orally 3 times/day. In addition, if the peripheral neuropathy is caused by diabetes, zinc sulfate can also be given as a sedative, and the rest is mainly based on the cause of peripheral neuropathy. For example, we need to know if the patient has diabetes, and if the patient is diabetic, we need to actively control blood sugar. If the patient has a history of peripheral nerve exposure to poisons and medications, advise the patient to stop using the poisons or medications.
