After middle age, with the deterioration of body functions and resistance, more and more diseases come to the door, so middle-aged and elderly people become more “regular” hospital visitors. After seeing various diseases, it is natural to take a large number of drugs, but how to take the specific drugs has become a big headache for many patients. According to years of clinical observation, there are at least two major misconceptions about reading medication instructions, one is that some patients blindly pursue the therapeutic effects of drugs, without looking carefully at the characteristics of the drug, regardless of the adverse effects of drugs, often overdose, a variety of drugs together, in order to achieve a rapid “drug to get rid of the disease” effect; another misconception On the contrary, too much concern about the adverse drug reactions, repeatedly entangled in the description of adverse drug reactions, ignoring the “cure” properties of the drug itself. These two misconceptions represent the thoughts and behaviors of many patients, and they are both irrational and unscientific ways to use drugs, which will have a significant impact on the treatment effect of diseases. How to read drug instructions scientifically and correctly may be confusing for patients who are starting out, but if you find its rules, reading it will be effortless. In short, a drug instruction manual that arrives is generally divided into 4 to 5 parts. If read completely, it must be an overwhelming task for the majority of patients. If we first follow the author’s thoughts to dissect, I believe we can all grasp useful information quickly. The first part of the description of the instruction is general information, including the chemical name and trade name of the drug, manufacturer, production and implementation standards, approval number and production lot number and expiration date, whether OTC drugs, etc. This part can be understood by simply browsing, because it is mainly useful for management and hospital drug procurement departments. The second part describes the pharmacological properties of the drug, including the chemical structure of the drug molecular formula (Western drugs) or formula (proprietary Chinese medicines), the pharmacological toxicology of the drug, the absorption and metabolic properties of the drug, half-life, and excretion mode, etc. Many pharmaceutical companies will provide a large number of clinical research data and evidence-based reports in this part. Generally, the readers of this part are mainly clinical doctors and pharmacists, and patients can ignore it. The third part is the main body of the instruction manual, describing the indications and contraindications of the drug, dosage and administration, which needs to be read carefully by patients. When reading it, you need to pay attention to the dose size, the way to take, the time to take and the interval. The indications and contraindications are generally understood, because the doctor has taken into account the specificity and applicability of the drug when prescribing. The fourth part is the adverse drug reactions, for this part of the content must be read with a rational point of view. Because now responsible pharmaceutical companies are very important to adverse reactions, and strive to be as detailed as possible in the instructions (especially foreign pharmaceutical companies), so it is easy to create the illusion that the side effects of drugs are particularly many, so that some patients dare not use. In fact, adverse reactions are listed for a large group of patients, specific to the individual these adverse reactions may not all appear, otherwise the drug is likely to be “shot” in the development process, it is not possible to market. In short, drug instructions are not a book of heaven, the general public can master, as long as the above approach to read, you can make it for my use, better complement the information received from the doctor, so that the drug to play a positive effect of treatment of disease, health protection, while minimizing the appearance of adverse reactions.
