At present, the cause of psoriasis is not yet known, although new treatment drugs and methods keep emerging, and although clinical cure can be achieved, it still cannot be cured. The contradiction between psoriasis patients’ eagerness to seek a cure and the fact that the disease itself cannot be cured has led to the patients trying all kinds of treatments blindly, resulting in repeated aggravation of the disease, and life-threatening cases such as liver and kidney damage, femoral head necrosis, and even leukemia in serious cases. In our daily clinical work, we often meet silver friends who buy medicines on their own for treatment, which leads to serious consequences, summarized as the following three situations: 1. Patients buy their own medicines from previous hospitals for treatment of psoriasis, which is prone to recurrent episodes: patients have been dealing with medicines for a long time, which has made them form their own experience in psoriasis treatment, and then patients feel that it is too troublesome to go to the hospital, waiting in line for a long time, and the doctor is just The patients also feel that it is too troublesome to go to the hospital, the waiting time is too long, and the doctors are just prescribing these kinds of medicines, so they buy the previous treatment medicines by themselves for their own convenience. Do not know, whether it is systematic use or external therapeutic drugs, have their indications, contraindications and adverse reactions, the choice or adjustment of drug therapy needs to be based on the patient’s condition, adverse drug reactions, physical condition, personal wishes and other circumstances, and is not set in stone. Doctors require patients to regularly review the purpose of this. For example, glucocorticoid topical treatment is fast and effective, but long-term use can lead to local skin atrophy and thinning, hirsutism, capillary dilatation, secondary infection and other adverse reactions. If patients do not use them in a reasonable and orderly manner under the guidance of doctors to minimize or avoid the above adverse reactions, but purchase and use them on their own for a long period of time, it will eventually lead to the occurrence of local and systemic adverse reactions. 2.Patients purchase their own Chinese medicine or proprietary Chinese medicine treatment Chinese medicine treatment, as a treasure of the motherland, is an important means of treating psoriasis. However, patients often wrongly believe that traditional Chinese medicine is natural and non-toxic, used in the treatment of psoriasis, even if it is invalid, it will not have any effect on the body. In fact, it is not true, but the medicine is three times poisonous, no matter the traditional Chinese medicine or western medicine is used inappropriately, it can cause damage to the organism. For example, Guanmutong, a Chinese medicine commonly used in the treatment of psoriasis, has been restricted from use because it contains aristolochic acid, a component that is toxic to the kidneys. Secondly, Chinese medicine emphasizes the importance of diagnosis and treatment, and doctors need to decide on the combination of Chinese medicine ingredients according to the patient’s individual situation. However, some patients often buy their own Chinese medicines or proprietary Chinese medicines for external or internal use based on medical books, Internet information, folk remedies, etc., which can easily bring physical harm and economic loss to patients. 3, patients blindly believe in advertising and propaganda Patients eager to seek medical treatment, expect the good intentions of the root cause is always being used by the wrongdoers, many false propaganda will appear “cure”, “root cause”, “pure natural”, “no natural”, “no natural”, “no natural”, “no natural”, “no natural”, “no natural”, “no natural”, “no natural”, “no natural”, “no natural”, “no natural”. Many false propaganda will appear “cure”, “root cause”, “pure natural”, “no toxic side effects”, “cutting-edge technology”, “biological or gene therapy” and other beautiful lies. Patients more than holding “try once is just a loss of money, maybe can cure” of the fluke, step by step into the trap of unscrupulous elements. Economic losses aside, more serious is part of the so-called “miracle drug” to achieve short-term results, will be added to glucocorticoids, immunosuppressants, anti-tumor drugs and other conventional circumstances need to be used with caution, so that the skin lesions short-term subside, so as to achieve “cure” illusion, inducing patients to long-term treatment. The illusion of a cure, inducing patients to buy long-term use to profiteer. But the patients are in the false image of the root of the health and life of the overdraft Clinical many psoriasis patients to buy their own medication of the painful experience, all reminding the silver friends remember psoriasis can not be treated indiscriminately, do not treat is also better than indiscriminate treatment, self-purchase of medication treatment is more unreliable. In the process of psoriasis treatment, psoriasis patients must go to regular hospitals and regular follow-up, not blindly pursuing near-term efficacy and ignoring the long-term harm.
