What should I do if I become drug-resistant after taking Natalizumab?

Any treatment choices and changes must be made under the guidance of a doctor and maintain good communication with the doctor in order to obtain the best treatment results. When patients are resistant to natalizumab (Natalizumab), the following steps are recommended:

Since everyone's constitution is different and their response to drug resistance is also different, doctors will confirm whether the patient actually has drug resistance. This can be determined by assessing the patient's clinical symptoms and disease activity, as well as performing relevant blood tests. If resistance develops, it is important to discuss it in detail with your doctor. Doctors can assess a patient's condition and provide targeted recommendations and treatment options. If natalizumab has failed, your doctor may recommend trying other treatments. For example, other immunomodulatory drugs, biological agents or oral drugs, etc. Based on the patient's specific situation, the doctor will develop a suitable treatment plan.

In addition to drug treatment, other treatment methods can also be considered, such as surgery, radiotherapy, immunotherapy, etc. It is important to closely monitor changes in the patient's condition after changing treatment regimens. This can be achieved through regular review and clinical evaluation, so that treatment plans can be adjusted in a timely manner to ensure that patients receive the best treatment results. At the same time, pay attention to the rational use of drugs and monitoring of side effects.

Natalizumab's original patent drug is not marketed in the country and cannot be included in medical insurance. Currently, the generic drug natalizumab on the market overseas may cost more than 8,000 US dollars per box (the price may fluctuate due to exchange rates), which is very expensive.
