From the aspect of adverse reactions: the drug should be “divided into two,†both to see that it has a side to treat the disease, and to see that it has an adverse reaction. Most drugs have more or less adverse reactions (such as allergic reactions, drug resistance, addiction, etc.). Some drugs have good curative effect, because they can cause adverse reactions, they have to give up when choosing drugs, and switch to drugs with lesser efficacy but less adverse reactions, such as coughing, unless necessary, more than codeine (slightly It is addictive) and uses cloperastine or pentomeline; it is generally not necessary to use morphine (easy addiction) and pethidine unless it is necessary for analgesia; And with berberine, and so on.
Some patients are slightly uncomfortable to take medicines themselves, which are blind, and do not consider the purpose of medication, nor the effect of medication. After a long time, it is easy to form drug dependence. Although most of the current drug manuals are easy to understand, it is impossible to elaborate all the adverse reactions. Be sure to prepare them before use. If you feel unwell, you should see them in time. Be wary of contraindications to drugs, and do not use them when there is an unsuitable application. For example, sulfa drugs are banned for patients with kidney disease. When patients have renal dysfunction, sulfa drugs should not be used.
If a single drug is used, it is more complicated. If multiple drugs are used together, the problem is more complicated. In general, the drugs used should not be abused unless necessary. Many patients are more eager to ask for more medicines. This is not good for treating patients. Because of the combination of multiple drugs, adverse reactions will occur frequently. Therefore, whether it is necessary to use multiple drugs, it is up to the doctor to decide according to the condition, in order to obtain good results.
A drug may have multiple dosage forms, so after selecting a drug, which dosage form should be considered. Because the injection works quickly, many people do not refuse to "hang the bottle", this is a very bad habit, but also a misunderstanding of the injection. To treat a disease, there are often several drugs that can be used. Which one should be used? It is mainly decided according to two aspects. From the perspective of efficacy: First, we must look at the efficacy of drugs on this disease. In order to cure as soon as possible, you should choose a good drug.
