In our recent question and also answer, the pharmacist discusses even if it is or not it is for sure to usage expired NyQuil.
You are watching: What happens if you drink expired nyquil
I was looking roughly in my medication cabinet critical night because that something to help with mine cough and also I uncovered an old party of NyQuil. The is expired, however not through much. Is that still okay to take?
Key pointsIn general, utilizing expired medications should be avoided as they might not be as potent or efficient as they when were Expired NyQuil has actually not been shown to degrade into harmful components, but expired products may have actually lost potency in time As NyQuil is relatively inexpensive, the is encourage to replace any type of expired product through an in-date one
In a basic sense, the is no recommended to take it any medication past the noted manufacturer expiration date, and this has NyQuil.
Now, it"s very uncommon the an expired medication will certainly "go bad" and cause physical harm and also there are no reports (at least that I could find) that expired NyQuil leading to harm. However, there definitely is a opportunity that that will have lost potency over time, do it much less effective.
Taking a medication that has actually lost potency could, that course, have serious consequences. Let"s say you take it blood push medication. If the doesn"t work as well as it should, you"re placing yourself at danger for an adverse outcomes (i.e high blood pressure).
because that a medication choose NyQuil, if it has actually lost potency over time, friend may find that it doesn"t relieve your symptom (e.g. Coughing, runny nose) and also an in-date product. Certainly not together dangerous together expired blood push medication, but it still isn"t ideal.
In many cases, if you room able to replace your expired medication, girlfriend should. This is definitely the situation for a drug prefer NyQuil, i beg your pardon is readily available.
With many expired medications, consisting of NyQuil, that is almost impossible come tell if they havelost potency in time without some sort of experimentation or analysis. Many drugs present no outward signs (with part exceptions, like aspirin).
How are Expiration days Determined?
This all leads to the question of exactly how expiration dates are actually identified in the an initial place.
A manufacturer for a provided drug will carry out stability test on their assets so have the right to determine the proper expiration date.
These stability tests will certainly be performed for a limited time period, usually two to three years. After ~ this duration of time, there isn"t any kind of data to show whether or no the medicine is stable. In various other words, the expiration is significant for yet long the manufacturer has data for.
While manufacturers could theoretically perform stability exam for longer periods the time, castle don"t yes, really have any type of financial impetus to perform so.
In addition, many medication is consumed in ~ a few years" time anyway, so longer tests are unnecessary.
Aside native the truth that medication deserve to degrade and lose potency with time (making them much less effective), it is necessary to keep in mind that some expired medication might be bald dangerous to take. Now, it is uncommon that a drug would certainly degrade right into harmful components, as mentioned earlier. However, some drugs execute undergo remarkable changes.
If friend have ever before opened a bottle of aspirin long past its expiration date, you may notification it smells prefer vinegar. This is due to the aspirin (salicylic acid) breaking down and producing acetic acid (vinegar). All at once though, it would certainly be extremely rare because that an expired medication to degrade into contents that room actually harmful come you.
The bigger worry is a ns in all at once effectiveness and also contamination. While a slim loss in effectiveness may no be a large deal for a drug favor NyQuil, there may be significant consequences with other drugs.
I used the example of a blood pressure medication above, with one more example gift antibiotics. If you space taking one for an infection and it is not as potent together it when was...there is a danger that it may not totally eradicate her infection, placing you at danger for complications.
As secondary point, some drugs (generally liquid-based) room at threat of ending up being contaminated with bacterial growth as preventive (used to limit bacterial growth) space only efficient for therefore long.
The takeaway allude here is that once your medicine is previous the listed expiration date, friend don"t know if it will certainly be for sure to take, or as effective as it once was.
Having said every one of the above, that is important to allude out that data from a variety of studies indicate that it takes a significant lot of time because that a drug to in reality degrade to the point where it has lost a huge percentage the its initial potency.
One of the biggest studies commissioned about medication expiration dates was excellent in the 1980s and also concerned the trial and error of medication stockpiles offered by the military. They found that the vast majority of drugs still had approximately 70-80% potential after 10 year if stored in the initial container! This led to the creation of the FDA Shelf Life expansion Program (SLEP).
Going earlier to expired Nyquil, that most most likely is for sure in regard to it not leading to harmful side effects.

It will likewise probably carry out a comparable level of efficiency to non-expired products due to the fact that it is unlikely to be substantially degraded but, as disputed in the sections above, there is simply no means to definitively know. Since Nyquil is easily accessible over the counter and is fairly inexpensive, it makes more sense to buy a non-expired replacement.
