Trigeminal neuralgia can be divided into two types: primary and secondary. Trigeminal neuralgia attacks are so painful and intense that it is difficult to control them by taking ordinary painkillers. Patients are like normal people in between attacks, but the slightest daily actions such as talking, eating, washing face, brushing teeth, etc. can cause trigeminal neuralgia. The first-line drugs for primary trigeminal neuralgia are carbamazepine and oxcarbazepine, which are typical drugs. I believe the vast majority of patients with primary trigeminal neuralgia are aware of these medications. We often say that drugs are toxic in three ways, referring to the fact that they have side effects. The obvious side effects of these drugs are: liver damage, gastrointestinal reactions, cardiac toxicity, and white blood cell effects. Nearly 27% of patients treated with carbamazepine relapsed due to dose reductions and 18% of patients treated with oxcarbazepine relapsed due to dose reductions. Only a minority of patients developed drug tolerance during treatment, and 3% of patients worsened after drug treatment. In addition to drug side effects that necessitate discontinuation of the drug in some patients, there are also perceived factors that lead to unsatisfactory results of drug therapy. A common phenomenon is not to use medication for a long time as prescribed by the doctor, often “forgetting the pain after getting well”. Do not follow the course of treatment, see the good and then close. When you see signs of improvement, you take your own medication at home, not according to the course of treatment, and the amount of medication is arbitrary, which has laid a hidden problem for later treatment. As a result of incomplete treatment, trigeminal neuralgia relapses and the condition becomes more and more serious. Some patients with trigeminal neuralgia may feel that it is troublesome and time-consuming to go to a big hospital, so they blindly take medicine by themselves and believe in the so-called “prescriptions”, without detailed diagnosis of their condition and receiving targeted treatment, delaying the best treatment period for trigeminal neuralgia. The best time to treat trigeminal neuralgia is delayed because you do not go to a regular hospital. The biggest advantage of medication is that it is easy to take, but the biggest problem is that it cannot cure trigeminal neuralgia. It can only control the pain in the early stage of the disease, as the medication time is getting longer, usually in about one or two years the effectiveness of the medication will also get worse. And with the increasing amount of medication, there are more and more side effects. There are also some patients who do not take the medication regularly, which may affect the effectiveness of the medication. Although medication is the preferred treatment for trigeminal neuralgia, if there are recurrent attacks or significant side effects, it is time to consider changing the treatment method. You can choose surgical treatment, or choose gamma knife treatment is also more efficient. At present, the best treatment effect of imported head gamma knife.
