In short, yes, expired medicines can be dangerous. This is because over time, medications can degrade and have a higher risk of being contaminated. A key thing we might be worried about is that you are not getting the treatment that you need, this could mean your condition isn’t being controlled properly which increases the risk of more serious complications. In this article we explore some frequently asked questions about using expired medicines such as “is it dangerous to take expired medicine?” and explain why this is not recommended.
What Does an Expiration Date Really Mean?
Despite how artificial medication might look, actually much like food, medicines can also expire. In fact it is just as important to be aware of the expiration date of medicines in the same way you wouldn’t want to drink spoiled milk and get nasty side effects (e.g upset stomach). However, unlike spoiled milk or rotting vegetables, it is very difficult to tell whether medication has degraded or expired such as by smelling or looking.
To save you from assessing the question of “is it safe to take expired medicine?”, the manufacturer of the medication will put an expiration date on the package to alert you to the point at which it is no longer certain that the medication is of the intended quality, safety, and specified strength. To identify this expiration date, the company would have done a lot of testing to check how quickly the active ingredient in the medication breaks down or at what point the medication can be contaminated. Thus, the expiration date, ‘use by’, or ‘best before’ date is the final day you can use the medication; it is advised that you dispose of the expired meds afterwards.
How Long Can You Use Medicine After the Expiration Date?
So how long can you use medicine after expiration date? Unlike with fruits and vegetables where you could eat them after the expiration date if they still look ok and not moldy, it is very difficult to judge medication as they can degrade at different rates. Generally, it is advised that you should not use medication after the expiration date. Additionally, some products may specify in the instructions that ‘once opened’ the duration of safe usage is much shorter than the expiration date. This is often the case in ointments, creams, or liquids. If you have not used up your medication and it has expired today, this does not mean you should rush to use it up all at once. Speak to your local pharmacist about disposing your current expired medication and replacing them with new ones as appropriate.
What Happens When You Take Expired Medicine?
Often, the risk of taking expired drugs is that it is a lower dose than what it is meant to be due to breakdown of the active ingredient over time. As a result you might experience:
- A weaker effect of the medicine: The lower dose may not be enough to control or improve the symptoms of your condition. For example, expired inhaler medication may mean your asthma is not well controlled. This might put you at a higher risk of asthma attacks.
- The medicine getting contaminated: This is more common with creams, ointments, liquids, and eye drops. Any type of medication that gets opened and used again and again can carry a risk of being contaminated with organisms like bacteria or fungi. Using out of date medicine could increase your risk of irritation or infection from using contaminated medication.
Is It Dangerous to Take Expired Medicine?
So what happens when you take expired medicine? It can be dangerous to take expired medicine. This is mainly because certain conditions rely on controlling symptoms with medication. If you are taking expired medication, the active ingredient may have degraded over time and may not be at the dose needed to control your symptoms. This can be worrying because the condition might get worse or there might be an increased risk of complications. For example, if you are taking expired antibiotics, your infection might not heal and also might get worse. Additionally, taking expired antibiotics might contribute to bacteria developing resistance to common antibiotics.
Also, some medications can be unsafe to use if they have been open for too long or are out of date. This is because they can become contaminated. A common example of this is eye drops that have been open or exposed for too long, it can be contaminated and cause an eye infection when used. If you are unsure about when your medication expires or if you have run out, please speak to a pharmacist or your healthcare provider for more information.
Are Expired Drugs Less Effective or Actually Harmful?
Let’s discuss what happens if you take expired pills in terms of two broad categories. You are advised not to take expired drugs because they can be both less effective or potentially harmful. It is recommended that you replace any expired medication.
| Less effective | Harmful |
| The active ingredient in medication can break down over time. When this happens, you might be getting a lower dose each time you take your medication. This can mean that you are not getting the right amount or strength of medication needed to control your condition. | Over time medication that is opened and used repeatedly such as creams, ointments, or liquids can risk being contaminated. Using contaminated medication can be uncomfortable or unsafe. Notably due to the risk of getting an infection. |
Regardless of whether it is a general health medicine or a more specific Men’s Health Medicine, it is important to respect the expiration date specified on the package.
Which Expired Meds Are the Riskiest?
While the general advice is not to use any out of date medication, it may be helpful to highlight some examples of medications where using them after the expiry date is particularly risky:
- medications that you inject (e.g insulin) can become contaminated or degrade past the expiry date
- eye drops or eye ointments can become contaminated when exposed which can lead to eye infections
- medications where a small change in dose can bring about big effects e.g medications for heart conditions
