Carbotriol is generally hormone-free, it belongs to the vitamin D derivatives and is commonly used clinically for the treatment of common psoriasis. It can correct the abnormalities in the proliferation and differentiation of the lesions, and is more effective in those with localized thickening of the skin or with larger and thicker plaques. Compared to hormones, the onset of action of carbofuran is slower, usually taking several weeks to achieve a stable effect, but the therapeutic effect can be maintained for a period of time after the effect is achieved, while other hormonal drugs may be more prone to relapse. At the same time, carbofurantrinol has fewer side effects, while hormonal drugs may cause side effects such as skin atrophy and hyperpigmentation. Capotriol is usually not dependent and can be used for a long time. If necessary, alternating carbotriol with hormonal drugs can also be used to enhance safety and control psoriasis effectively. Consult your doctor before using carbotriol, do not use it on your own. It is prohibited to use if you are allergic to any of the ingredients in the drug or if you have a calcium metabolism disorder, and it should be used with caution in women and children during pregnancy. Sunburn may occur after the use of the drug, so you need to take protective measures during the use of the drug. Do not let the drug touch your mouth, nose or eyes to avoid burns. In addition, carbofuran may irritate the skin of the face. If you experience discomfort after using the drug, you should seek medical advice and let the doctor decide whether to stop the drug or take necessary measures according to the severity of the adverse reaction.
