I have a terrible cough right now. I found some cough syrup in the back of the medicine cabinet labeled "acetominophen and codeine phosphate elixir". The date on the prescription bottle is May 19, 2004. (That's almost nine years ago.) It's working just fine... at least I am falling asleep and staying asleep - not being wakened up by that stupid hacking cough - so it must be okay...
Am I stupid to to do that? You bet! I would never recommend anyone else take medication that's been sitting in their medicine cabinet for 8 years plus. But in this case, and because it's "me", I'm really glad I never got around to throwing it out. Because it's really helping...
to increase shelf life
Pure codeine base is not very soluble in water, and has a short shelf life. When codeine base is mixed with a dilute strong acid, such as Sulfuric Acid, it forms a salt: Codeine sulfate. This salted version is more water soluble and has a longer shelf life. Most medicines are salted in this manner.
The shelf life of simple syrup is about one month when stored in the refrigerator. To extend its shelf life, you can add a small amount of vodka or other high-proof alcohol to inhibit bacterial growth, or heat the syrup to a simmer before storing it in a sterilized container.
Benzonatate is a cough suppressant. The shelf life of benzonatate expires within one or two years in which the drug begins efficiency and shelf life.
3 to 6 months
Tylenol with codeine is a form of medication that is used for pain relief and to reduce fever. The shelf life of Tylenol with codeine will depend upon the conditions in which it was stored and the printed expiration date on the outside packaging.
Yes, it is recommended to refrigerate simple syrup after making it to prolong its shelf life and prevent bacterial growth.
The shelf life of simple syrup is about one month when stored in the refrigerator. It can go bad if stored for longer periods, so it's best to use it within a month for optimal freshness.
Codeine phosphate can be detected in a person's urine for 2-4 days, and in their blood for up to 12 hours. It can be detected in a person's saliva for 1-4 days. Codeine is an ingredient in many types of cough syrup.
Pure codeine base is not very soluble in water, and it doesn't have a very long shelf-life. Such chemicals are often salted with a dilute strong acid to make them more water soluble and increase their stability. So Codeine Sulphate is Codeine base plus a little bit of sulphuric acid.
Not long around dope-heads.. I would guess about 20 seconds!
No, corn syrup is not a preservative. It is a sweetener made from corn starch. Preservatives are substances added to food to prevent spoilage or extend shelf life, while corn syrup is primarily used as a sweetening agent.
