What are the general medication precautions? 1, pay attention to avoid abuse: to prevent adverse reactions. Abuse of drugs not only causes material waste, but more seriously can bring all kinds of pain to the patient. 2, pay attention to the patient’s medical history: for example, for patients with gastrointestinal spasm and suffering from glaucoma, if they ignore their glaucoma history and apply atropine treatment, it will lead to adverse consequences. 3, pay attention to the selection of the most appropriate method of administration: the method of administration should be based on the urgency of the disease, the purpose of the drug and the nature of the drug itself, such as critical cases, it is appropriate to use intravenous injection or static drip; trichomoniasis, more vaginal plug; treatment of intestinal infections, gastritis, gastric ulcers and intestinal worms. It is easy to take orally. 4, pay attention to prevent the accumulation of poisoning: there are some slow excretion and toxicity of drugs (such as digitalis, Stilbene, emetine), in order to prevent the accumulation of poisoning, when used to a certain amount should be stopped or given a smaller amount (maintenance amount), such drugs, because it is easy to cause the accumulation of poisoning, so try to avoid the use of liver, kidney insufficiency of patients, and provide a certain number of consecutive administration or a certain period of time as a course of treatment The number of consecutive doses or a certain period of time is prescribed as a course of treatment. After the completion of a course of treatment, if the drug needs to be repeated, the drug should be stopped for a certain period of time before starting the next course of treatment. 5, pay attention to avoid drug interactions and contraindications: the contraindications should pay attention to two aspects: (1) to avoid pharmacological contraindications (i.e., the efficacy of the drugs together to cancel or reduce each other, or to increase their toxicity), in addition to the pharmacological effects of the drugs against each other, such as central stimulants and central inhibitors, antihypertensive drugs and antihypertensive drugs, etc. ~ generally should not be combined, but also pay attention to some other pharmacological contraindications that may be encountered. (2) physicochemical contraindications, the main attention must be paid to the compatibility of acid and alkaline drugs. Riveting such as: acetylsalicylic acid and alkali drugs with bulk, when wet, easy to cause decomposition; alkali salts (such as morphine hydrochloride) solution, when encountered with alkaline drugs, can make alkali precipitation; in the mixed intravenous drip of contraindications, mainly acid-base pairing, for example, penicillin with procaine, promethazine, chlorpromazine, etc., can produce precipitation and so on. 6, the use of new drugs must be careful: before starting to use should refer to the relevant information, to make a good idea. In the trial, attention should be paid to observe the efficacy and long-term and recent toxic reactions. For some new drugs, attention should also be paid to observe whether they are carcinogenic, teratogenic, addictive, allergic reactions, etc. The dosage should generally start from a small dose of the dosage presented in the data, and then adjust the dosage according to clinical experience, but should not exceed the prescribed extreme amount to ensure patient safety.
