Many families stock up on common medicines for emergencies. However, many families have the consciousness to prepare drugs, but lack the consciousness to regularly clean up these drugs, resulting in some expired and deteriorated drugs endangering health. Drugs, like food, will expire and deteriorate. There is no small harm when taking expired drugs. The efficacy of expired drugs is unstable. After taking them, not only can they not exert their efficacy and treat diseases, but also they can delay the disease, leading to the aggravation of the disease. Some expired drugs will deteriorate, which will not only cause adverse reactions, but even endanger life safety in serious cases. Expired drugs that are not cleaned up in time at home are easily taken by the elderly and children. I remember that when I was at home during the new year, my stomach was uncomfortable, so my grandmother took out the snack tablets she had bought before. I took a look at the shelf life and found that it had expired for more than half a year. Young people generally pay more attention to the shelf-life of drugs, but the elderly often do not have this awareness and ignore the shelf-life of drugs. If they are not careful, they will take expired drugs, causing serious consequences. In order to avoid the adverse reactions caused by expired drugs and avoid the shortage of drugs in urgent need, the family must clean up and update the stored drugs in time. It should be noted that the expired drugs cleaned out cannot be thrown away. Drugs often contain a variety of chemical components. If they are discarded, it is likely to cause environmental pollution and damage the surrounding ecology. In addition, some people will repack the expired drugs and put them on the market again. Therefore, the out of date drugs should be recycled through formal channels. At present, many places regularly recycle expired drugs. Some pharmacies also have recycling boxes all year round. It is suggested to regularly clean and update the drugs stored in the home and put them into the regular recycling site. (outlook new era)
