Can Demerol be used after it expires?

It is important to note that pethidine cannot be used after it expires. This is mainly because the chemical structure stability of this drug has been lost after it expires. Once expired pethidine is found, it should be scrapped. The hazards of expired pethidine are still unclear, but even so, setting a shelf life means that it will lose its efficacy after the expiration date and will have no effect if used again.

Generally, the drugs in ampoules do not have obvious color changes or precipitation. Most of them can still be used after expiration, and the efficacy will not be reduced. Before the 1980s, many drugs did not have expiration dates. However, all drugs currently have a clear expiration date. If adverse reactions occur after their use, the doctor will bear 100% responsibility!

Any expired medicine should not and is not allowed to be used on patients, because expired medicine may undergo qualitative changes, such as the growth of microorganisms and changes in the original chemical structure, which may cause unpredictable consequences. Of course, it is also possible that it may expire without any change.

No medicines can be used. Unlike expired food, eating it will at most cause diarrhea. If medicines are expired, the problem won’t be as simple as diarrhea. If you are lucky, you will be fine. If you are unlucky, you may die in a few seconds if rescue is not timely. Expired drugs cannot be used because their chemical properties have long since changed. Although there may be no changes in appearance, the actual chemical properties have long since changed. In addition, these are narcotic drugs with analgesic effects and cannot be used for a long time. Long-term use can be addictive.

Demerol is also called pethidine hydrochloride. This drug is an opioid receptor agonist and is mainly used for analgesia in clinical practice. The drug itself is a white crystalline powder with a bitter taste, but it is not processed in any way. The analgesic effect of pethidine is very similar to that of morphine. If it is found that pethidine has expired, it is prohibited to use it.
