What are the general medication precautions?1. Pay attention to avoid abuse: prevent adverse reactions. The abuse of drugs will not only cause material waste, but more seriously will 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 glaucoma, if the glaucoma history is ignored and the application of atropine treatment will lead to adverse consequences. 3, pay attention to the selection of the most appropriate method of administration: the method of administration should be decided according to the urgency of the disease, the purpose of the drug and the nature of the drug itself, such as for For example, for critical cases, intravenous injection or drip is appropriate; for trichomoniasis, vaginal plug is used; for 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 a certain amount should be used to stop the drug or give a smaller amount (maintenance amount), these drugs, because it is easy to cause accumulation of poisoning, so try to avoid the use of patients with hepatic and renal insufficiency, and provide a certain number of consecutive doses or a certain time As a course of treatment. 5, pay attention to avoid drug interactions and contraindications: contraindications to pay attention to two aspects: (1) avoid pharmacological contraindications (i.e., the efficacy of the drugs in combination cancel each other out or reduce, or increase their toxicity), except for the pharmacological effects of drugs that oppose each other, such as central stimulants and central inhibitors, antihypertensive drugs and antihypertensive drugs, etc. In addition to drugs with opposing pharmacological effects such as central stimulants and central inhibitors, antihypertensive drugs and antihypertensive drugs, etc., some other pharmacological contraindications should be noted. (2) Physicochemical contraindications, mainly attention should be paid to the compatibility of acidic and basic drugs. For example, acetylsalicylic acid and alkali drugs with bulk, when wet, easily caused by decomposition; alkaloid salts (such as morphine hydrochloride) solution, in the presence of alkaline drugs, alkaloids can be precipitated; in the mixed intravenous drip of contraindications, mainly acid-base pairing, for example, penicillin with procaine, promethazine, chlorpromazine, etc., can produce precipitation, etc. 6, the use of new drugs must be cautious: before starting to use The first thing to do is to refer to the relevant information to have 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 be paid to 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.
