Does Aspirin Expire? And Why?

Aspirin, also called acetylsalicylic acid is an over-the-counter medication used for reducing pain and inflammation.

What is Aspirin Used For?

  • Aspirin reduces fever
  • It is used to moderate mild-moderate pain
  • Aspirin reduces swelling (anti-inflammatory)
  • Low dose of aspirin is used to thin blood to prevent blood clots

You will often determine the shelf life of aspirin by checking the best-by date displayed on the packaging, as well as the manner in which the product is stored.

So, how long is the shelf life of aspirin? When stored properly, aspirin has a shelf life of roughly two years after its best-before date…

It goes without saying that if aspirin is not stored properly, its shelf life will be significantly reduced, therefore be sure to read the section on proper storage. We have included a “+” next to the number of years since this product will last for many years after the best-buy date has passed, but the effectiveness of the active ingredient will begin to decline below widely recognized levels as the number of years on the shelf increases.

Does Aspirin Expire?

Aspirin expires 2-3 years after the date of manufacture. It is usually effective for another 12 months after expiration date stamped on the package. Bayer AG recommends that you should discard Aspirin that has passed its shelf life.

Aspirin that has expired begins to smell like vinegar. Taking expired aspirin, on that same note, is unlikely to accomplish much other putting you at risk.

The risk of taking expired aspirin will be dependent on its chirality changes, the circumstances under which it was stored, and any contamination it was exposed to.

Here’s the real deal on Aspirin’s expiration date

Take, for example, aspirin. According to Bayer AG, aspirin has a shelf life of two or three years and should be thrown out after that time period. Chris Allen, a vice president at the Bayer department that manufactures aspirin, however, believes that the date indicated is “quite conservative.”

When Bayer tested four-year-old aspirin, the results showed that it was still 100 percent effective.

So why hasn’t Bayer imposed a four-year expiration date for its products? This is due to the fact that the corporation frequently changes its packaging and engages in continual development efforts. Each change necessitates the requirement for additional expiration-date testing, which would be impracticable if the product had a four-year shelf life and was tested each time.

Bayer has never conducted a study on aspirin that lasted more than four years.

What Happens As Aspirin Expires?

Aspirin, in particular, has a subtle ‘vinegary’ odor to it, which you may notice if you take a sniff of it. Acetic acid is what you’re smelling if you’re taking expired aspirin, which is chemically degrading over time and causing the odor. Despite how terrible it may smell, most studies have found that if the medication is within a few years of expiration, it will likely retain more than 95 percent of its original efficacy and will not be harmful to consume.

Should You Used Expired Aspirin?

You should not use expired aspirin because it breaks down into acetic acid and other chemicals that may be unsafe. Therefore, if the aspirin bottle smells like vinegar, you should avoid using it since it will quickly decompose into acetic acid and other harmful compounds.

Those who take medicine in an unstable form, such as fizzy pills or tablets meant to melt in the mouth, will be considerably more susceptible to the medication.

If medicine is stored in an environment with excessive humidity or at a temperature that is higher than normal, it can go bad even before the expiration date on the package.

Because aspirin is available over-the-counter and is relatively affordable, it is usually more economically feasible to just order a replacement dose.

The fact that there are generally too many unknowns means that you will rarely hear a doctor or other health-care expert advocate that it is OK to use expired medications like aspirin.

Using good hygiene and drug safety measures will assist to reduce any health risks.

How to tell if Aspirin is bad, rotten or spoiled?

Expired aspirin pills will typically have a chalky texture rather than a hard and smooth consistency, which is a common characteristic of bad aspirin tablets. Tablets that have passed their expiration date will easily crumble into a powder when squeezed. Earlier versions of the drug are white, and as they go stale, they will typically turn yellow in hue. Gel pills will become flexible and sticky as a result of this. The coating on the tablets will make it more difficult to discern any signs of age.

When it comes to spoiled aspirin tablets, moisture or heat are frequently to blame. However, the effects of age alone on any sort of prescription might be detrimental because the molecules in the medication can alter over time. If you use aspirin after its best before date, it may fail to perform the function for which it was meant and may merely provide false hope for your headache.

If the aspirin is producing a vinegar smell to, it has outlived its shelf life and should be thrown away immediately.

The active ingredient or component in aspirin is created through a chemical interaction between acids, and when heated or aged to severe temperatures, a reverse chemical reaction happens, separating the active ingredient and the inactive ingredient once more. One of the acids is also the active element in vinegar, which explains why ruined aspirin will smell like vinegar, and the other acid is known to upset stomachs, which is what would happen if the aspirin was ingested whole.

Although aspiring may last many years before going bad, the effectiveness of its active ingredient diminishes over time as the drug becomes less effective. This is an extremely long and drawn-out process that will take several years.

As a result, an aspirin that is several years old but has not gone bad might still be effective in relieving a headache.

However, if you suspect that they are older, you should not increase the amount of aspirin you are taking because an overdose of any drug can be harmful to you.

When it comes to liquid aspirin, I recommend that you follow the expiration date more closely as indicated by the manufacturer. Toss the bottle after its expiry.  This is due to the fact that liquids are considerably more likely than tablets to develop bacteria.

As with any meal, there are potential health concerns linked with it. Always remember to maintain drug safety and to consume the medicine before its shelf life has ended.

Do Baby Aspirin Expire?

Every medication, including baby aspirin and other over-the-counter medications, have an expiration date. This is set to make sure the medicine is safe to use and will function as intended. To summarize, baby aspirin (81 mg) is a medication that has an expiration date.

How to store Aspirin to extend its shelf life?

As with any medication, aspirin must be stored and handled carefully in order to maximize its shelf life.

Aspirin should be stored in a cool, dry location where the temperature remains as consistent as possible.

In order to maintain airtightness, ensure that the container’s lid is properly re-sealed after use. The cotton ball should be kept within the aspirin container not only to absorb any possible moisture from the environment, but also to avoid breakage of the pills and to reduce excess air trapped inside the container. Keep your fingers away from the aspirin bottle, but if you really must reach in, make sure to wash your hands thoroughly before doing so.

Some of the advantages of efficient food storage include eating healthier, saving money on food, and helping the environment by reducing food waste.
