Does infliximab need to be used for life?

Whether Infliximab needs to be used for life depends on the type of disease the patient has, how well the disease is controlled, and the individual's response to the drug. As an anti-TNF-α (tumor necrosis factor α) monoclonal antibody, infliximab is mainly used to treat a variety of chronic inflammatory diseases including Crohn's disease (CD), ulcerative colitis, rheumatoid arthritis (RA), ankylosing spondylitis, psoriatic arthritis and other chronic inflammatory diseases. Most of these diseases are chronic, relapsing, and autoimmune-related, and are often difficult to completely cure through short-term treatment. Therefore, in most cases, the use of infliximab has the characteristics of long-term or even lifelong maintenance.

But not all patients require lifelong use. Clinically, on the premise that the condition is relieved and stable, some patients can gradually extend the medication interval under the guidance of a doctor, or even try to stop medication. However, such attempts to reduce or discontinue medication must be strictly evaluated and monitored, and treatment often needs to be restarted in the event of relapse. Therefore, the medication cycle of infliximab should be highly individualized, and it is not recommended to stop the medication or change the dose on your own. For some patients, continued use of infliximab becomes a necessary treatment option in order to maintain long-term disease remission and prevent recurrence and complications.

In addition, long-term use of biologics also requires weighing efficacy against potential risks, including infection risks, drug resistance, and economic burden. The medical consensus tends to "use the least amount of drugs to control the biggest problems." On the basis of ensuring the efficacy, gradually reducing drugs or switching to other low-risk options is also an important direction of clinical management. In short, there is no unified answer to whether infliximab needs to be used for life. It is recommended that professional doctors evaluate and adjust treatment strategies based on the patient's condition.
