Carbamazepine is more effective when treating trigeminal neuralgia and glossopharyngeal neuralgia. Carbamazepine is an anticonvulsant and antiepileptic medication that can be used to treat neuralgia due to its ability to block nerve conduction, and is the drug of choice for treating primary trigeminal neuralgia, relieving patients from the symptoms of pain, and as a prophylactic medication. Carbamazepine is effective in relieving pain due to its inhibition of abnormal nerve discharges, but it does not necessarily cure neuralgia. People who are allergic to carbamazepine, patients with bone marrow suppression and liver insufficiency should be prohibited from using it. Neuralgia has many causes, it is recommended that patients with neuralgia consult a doctor in a timely manner to identify the cause of the disease and then take targeted treatment, do not blindly take medication on their own.
