First of all, we should know what kind of drugs are defined as expired drugs: those whose active ingredients are less than 90% of the original drugs are regarded as expired. In fact, 90% of the ingredients are effective after expiration, but 10% of the ingredients have changed and lost their functions. I work in a western pharmacy. Of course, expired drugs can't be distributed to patients and can't be used any more. We have to get rid of it, but sometimes we still eat it ourselves, and the effect is still very good. That's for sure. But we advise you not to take it, because after all, 10% of the ingredients have deteriorated, and the consequences are unpredictable. Xiaoyao pill is a Chinese patent medicine, which is much safer than western medicine chemicals. I think you can take it if the expiration time is not long, after all, 9 1% of the active ingredients (the drug has not expired at this time) and 89% of the active ingredients (the drug has expired at this time).
