How long it usually takes for psoriasis to recur with biologics varies widely among individuals and is not yet supported by clear data. Biologics, including alfacalcitab, efalizumab, and etanercept, are currently more effective medications for the relief of psoriasis, and can control the disease in the short term, but there is no research data on whether or not they will relapse and how often they will relapse. Biologics can be considered for patients who are not effective on traditional treatments and who meet the indications for use of the drugs, but biologics usually have a longer course of treatment and need to be maintained after controlling the disease. However, the treatment course of biologics is usually longer, and patients still need to maintain the treatment after controlling the disease. Different physical condition and irregular use of drugs may lead to relapse, so it is recommended that patients communicate with their doctors and fully understand the advantages and disadvantages of biologics before choosing whether to apply them or not. If you want to use biological agents to treat psoriasis, it is recommended to go to regular hospitals, consult with professional doctors, complete the relevant examinations, and apply them in a standardized way under the guidance of doctors, so as to avoid blind treatment.
