Pharmacies are now popping up everywhere and there are indeed many online pharmacies, which greatly facilitates patients and may reduce some of their medical costs. Dermatologists often see many patients in the clinic purchasing their own medications from pharmacies, or patients going to pharmacies to pick up their medications after their doctor has prescribed them. Dermatologists are not opposed to patients purchasing their own medications, but strongly recommend that they do so under the guidance of a professional dermatologist. Although the benefits of self-purchase are greater than the costs, it does not stop patients from shopping on their own. Many people think that skin diseases are minor and that it is enough to buy some medicine from the pharmacy. However, there is something to be learned from shopping for your own medication. This is probably what most patients would like to know, but as a dermatologist, we do not recommend that patients buy topical skin medications in pharmacies or online. If that’s the case, why write this article? Because the urge to buy drugs on their own is too strong, and to avoid patients making some unnecessary mistakes when buying drugs on their own, dermatologists should talk about how to buy topical skin medications on their own. The actual dermatologists are going to be able to get a lot more than just a few of the most popular and popular drugs. A qualified drug can be used clinically, generally to be widely used in clinical trials by the ground and human experiments, which there are many drugs are not suitable for clinical or large-scale use, the production had to be discontinued in the middle. Many of these drugs are not suitable for clinical use or are used on a large scale and have to be discontinued. The FDA generally gives these qualified drugs a lot number, indicating approval for clinical application. Therefore a qualified and safe drug, generally has a drug approval number, which is generally the drug approval word plus a bunch of letters and numbers. Generally on the outer packaging of the drug can be found. On the contrary, a lot of drugs in pharmacies are not real drugs, at most cosmetics or disinfectants, these drugs do not have the State Drug Administration number, usually a drug or makeup word, or even the health of the word, national food or health, which is nonsense, disinfectants and even health products can cure? The second look at the efficacy of drugs, if a so-called drug to say the efficacy of the ceiling, what diseases are cured, this drug is simply not credible, the last is what diseases can not be cured. There are many kinds of skin diseases, some are infectious, some are allergic, and many others, you can see the classification of dermatologists. The pathogenesis of many of these diseases is simply the opposite, that is, if the wrong one is used, that does not treat at all, but will aggravate the disease. Therefore, when buying drugs, be sure to look at the efficacy, for the treatment of a single disease the highest credibility of the drug, and vice versa low credibility. In addition do not overly believe in what Miao medicine, Tibetan medicine, Mongolian medicine and other drugs. Dermatologists do not deny the efficacy of traditional minority medicines, but many manufacturers now sell their products with very little real minority medicine in them. The first time you enter a pharmacy, the clerk is so enthusiastic that he or she will introduce and recommend certain drugs to you. Sometimes patients want to buy a drug drug, the clerk will put this drug down to nothing, but will give you a recommendation for another drug. For this situation, listen less to their foolishness. The more they strongly recommend you to buy a drug, the most profitable this drug, the efficacy is not necessarily, but the cheaper drugs may be more effective. Therefore, when buying drugs, do not look at the price, do not think that the higher-priced drugs are more effective, it is not necessarily. You should not listen to the shopkeeper, but have your own opinion and understanding. Lastly, dermatologists recommend that patients purchase medications under the guidance of a professional dermatologist.
