The price of each injection of biological agents is 1,000 to 5,000 yuan, and the cost of biological agent treatment for psoriasis ranges from a few thousand to tens of thousands of dollars due to the different courses of treatment. The cost of treatment will be different due to the different specific conditions of patients, different biological agents used, different courses of use, different local health insurance policies and types of health insurance. If the condition is more serious and the area of skin lesions is larger, then the treatment cost is higher. Biologics can control the symptoms of severe, refractory and specific types of psoriasis very quickly, but they can also bring serious adverse effects, such as increasing the risk of infection and malignancy, and increasing the cost of later treatments. If you suffer from psoriasis, it is recommended that you visit a regular hospital for information and treatment as prescribed by your doctor.
