Do not blur the difference between prohibition, caution, and discretion
The instructions for medications often contain words such as "prohibition," "caution," or "discretion." Although these three words differ by only one letter, their requirements are completely different. It is important not to overlook the differences between them.
1. Prohibition
This means that the use of this medication is prohibited because some patients may experience adverse reactions. For example, morphine has the effect of suppressing the respiratory center, so it is prohibited for patients with bronchial asthma or pulmonary heart disease. Similarly, some people are allergic to penicillin, so it is a prohibited drug for them.
2. Caution
This refers to the possibility of adverse reactions in certain patients after taking the medication. For example, isopropylantipyrine (Remifentanil) has a harmful effect on liver cells and may increase alanine aminotransferase levels, so it is cautioned against use in patients with liver dysfunction. Pregnant women within the first three months should avoid the use of mifepristone (Mifegyne) as it may cause fetal malformation.
3. Discretion
This means that the medication can be used with caution, and any adverse reactions should be closely monitored. If any occur, the medication should be discontinued immediately. For example, aspirin can cause excessive gastric stimulation, so it should be used with discretion in patients with gastric ulcers. Discretionary medications can be used cautiously under the guidance of a doctor if necessary.
