Liquid medicine cannot be used after its expiration date. First of all, after the drug expired, the content of the active ingredients would decrease, and it would not be able to play its original effect. Secondly, its chemical composition may undergo reactions such as oxidization and decomposition, which may increase toxic side effects and allergic reactions. The country's regulations on the shelf life of drugs were determined by the potency of the drugs. The potency of expired drugs would not only reduce the treatment effect, but also produce unknown unsafe substances that might cause adverse effects on the human body. In addition, due to the long-term storage of liquid medicine, it would react with certain substances in the air and may also cause harm to the human body. Therefore, for safety reasons, expired liquid medicine should not be used. Read more exciting novels for free

Can expired drugs still be eaten? Is it poisonous?

Medicines that have just expired are not recommended. On the one hand, after the drug expired, the stability of its chemical composition would decrease, and the content of the active ingredient might be significantly reduced, which would lead to the failure of the drug and delay the disease. For example, the efficacy of cephem and penicillins weakened after they expired, and the expected efficacy could not be achieved after taking them. It might cause a long-term infection, or even delay the treatment time and cause infectious shock. On the other hand, some drugs may decompose and produce toxic substances after they expire, increasing toxic side effects and allergic reactions. For example, long-term storage of Aspirin will decompose into compounds of sulfuric acid and sulfuric acid that are irritating to the digestive tract. After taking it, it will cause discomfort in the digestive tract, and may even lead to gastric ulcers, gastric bleeding, and gastric Perforation. When drugs such as Natroprusside expire, they may decompose into cyanides, which may endanger life after taking them. Although there were no public reports confirming that the use of existing expired drugs would cause obvious side effects in the human body, it was not recommended to take expired drugs from a safety perspective. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

If applied to the plant, it might destroy the plant's physiological balance, resulting in growth obstruction or withering. Moreover, the expired medicinal liquid might be affected by the polluting substances in the environment. These polluting substances were toxic to plants and might also affect human health. They might also seep into the soil and water sources, causing pollution to the environment. From the perspective of composition, heavy metals such as lead and mercury contained in some expired drugs may accumulate in the soil and be absorbed by plants. Not only is it detrimental to plant growth, but the accumulation of these heavy metals may also have a negative impact on human health. Moreover, the efficacy of the expired medicinal liquid would be greatly weakened or ineffective, and it would not be able to promote the growth of plants as expected.
