Key takeaways
- Expired amoxicillin isn’t toxic, but it degrades over time and may have lost potency. Taking it can allow bacteria to adapt and become antibiotic resistant, making future treatments less effective.
- Liquid amoxicillin expires in 14 days because it’s more prone to microbial growth and degradation than solid forms. It requires refrigeration to maintain stability.
- Amoxicillin capsules and tablets typically last 2 to 3 years when stored properly, but you should avoid taking any form after its expiration date to ensure effectiveness.
Overview
Amoxicillin is a common antibiotic doctors prescribe to treat bacterial infections, such as tooth infections, strep throat, and urinary tract infections (UTIs).
It comes in various forms, including:
- capsules
- tablets (chewable and regular)
- oral suspension (liquid)
All forms of amoxicillin require a prescription from a healthcare professional. It is not available over the counter. Amoxicillin is a generic drug, but it comes in brand-name versions like Amoxil and Moxatag.
You should typically avoid taking expired medication because it can make your treatment less effective and increase the risk of side effects.

Can expired amoxicillin harm you?
Although expired amoxicillin is not toxic, it can still have harmful effects. So, doctors do not recommend taking expired amoxicillin.
Amoxicillin degrades over time. This means it has likely lost some of its potency and will not provide the therapeutic benefit you need. You won’t be able to tell if amoxicillin has degraded by looking at or smelling it, so it’s best to follow the expiration date that the drug manufacturer provides.
If you take expired amoxicillin, it may not be as effective in treating infection-causing bacteria. It could help these bacteria to adapt and become resistant to antibiotics. According to the Food and Drug Administration (FDA), antibiotic resistance can make future treatments less effective. That means the next time you need amoxicillin, it might have little or no effect.

Liquid amoxicillin is a solution containing powdered amoxicillin mixed with water. It has a short shelf-life of only 14 days, and you will need to keep it in the refrigerator.
Liquid amoxicillin expires more quickly due to several factors, such as:
- Microbial growth: Liquid medications may not contain preservatives. So, they are more susceptible to contamination by bacteria and microbes, which can grow in the solution over time. This can affect the safety and efficacy of the medication.
- Stability: Liquid medications, including amoxicillin, are more prone to degradation compared to solid forms due to the way they’re made up. The active ingredients in liquid medications can break down over time, decreasing the drug’s effectiveness and potency.
- Storage: Liquid medications are often more sensitive to environmental factors such as light, temperature, and humidity. Improper storage conditions can speed up how quickly the drug’s active ingredients degrade, leading to reduced effectiveness.
The 14-day expiration period for liquid amoxicillin is in place to ensure the medication’s effectiveness and safety. It is important to adhere to expiration dates and storage guidelines to ensure you’re getting the intended benefit of the medication.
How long is amoxicillin good for after the expiration date?
How long amoxicillin lasts after its expiration date will depend on its form. According to a 2019 study, solid drug forms, such as tablets and capsules, appear to be most stable past their expiration date.
Drugs that require refrigeration and come as a reconstituted suspension or solution, like liquid amoxicillin, may not have the required potency if you use them past their expiration date.
Loss of potency can be a major health concern, especially when treating an infection with an antibiotic. Also, antibiotic resistance is more likely to occur when you take expired medications.
Amoxicillin capsules and tablets typically last for about 2 to 3 years before expiring when stored properly. However, pharmacists often mark the expiration date as about 1 year, as long as that date falls within the expiration date on their stock bottle of amoxicillin.
Since you won’t be able to know exactly when the drug was manufactured, you should not take amoxicillin capsules and tablets after the expiration date. Liquid amoxicillin typically expires after 14 days. You should avoid taking liquid amoxicillin after its expiration date has passed.
It’s also important to make sure you store your amoxicillin properly. You should keep the amoxicillin capsules and tablets in a light and moisture-resistant container at room temperature. Liquid amoxicillin is best kept in your refrigerator to maintain stability and limit degradation.
Summary
Although expired amoxicillin is not toxic, you should avoid taking it. If you take expired amoxicillin, it may have lost its potency. This means it may not be as effective in treating your condition. There’s also a risk that bacteria may adapt to become resistant to this antibiotic, meaning that amoxicillin may not work the next time you need it.
It’s important to pay attention to the expiration dates labeled on antibiotics and store them properly. Amoxicillin oral capsules and tablets typically last 2 to 3 years, and amoxicillin oral suspension typically lasts for 14 days. After this time period, you should dispose of any leftover amoxicillin.
