Are You Taking Expired Medicines Without Realising It? Here’s Why It’s Risky and What You Can Do

When it comes to medicine, the expiry date isn’t just a suggestion, it’s a health safeguard.

From everyday painkillers to prescribed antibiotics, taking expired medication can do more harm than good. In fact, outdated medicines may not only lose effectiveness, but in some cases, they can even become harmful. Yet many people across England overlook this simple but essential health check.

In this guide, we’ll explain why checking expiry dates is a vital part of your personal healthcare routine, what risks expired medicines can pose, and how platforms like pHarmatonic can help you manage medications safely at home.

Why Do Medicines Have Expiry Dates?

Pharmaceutical companies are required by law to test how long a medicine remains effective and stable. This is known as shelf life, and it determines the expiry date you see on packaging or blister packs.

After this date, the manufacturer no longer guarantees:

• The drug’s strength or effectiveness
• Its ability to treat the intended condition
• Its safety profile

Some medications might degrade slowly, while others break down faster due to moisture, heat, or light exposure. Even a slight change in a medicine’s chemical composition can trigger allergic reactions, gastrointestinal issues, or organ stress.

What Happens If You Take Expired Medicines?

1. Reduced Effectiveness

This is especially dangerous in:

• Antibiotics (can lead to antibiotic resistance)
• Heart or blood pressure medications
• Diabetes management drugs
• Inhalers for asthma or COPD

2. Increased Risk of Side Effects

Chemical breakdown can create new compounds, some of which may be toxic or irritating to the body.

3. Delays in Proper Treatment

By taking a medicine that no longer works, you delay proper treatment and potentially worsen your condition.

Common Mistakes People Make With Medicines

• Keeping leftover antibiotics “just in case”
• Not checking expiry dates before use
• Using eye drops or creams long after opening
• Storing medicines in warm or humid environments (like the bathroom)
  

These habits, although common, can put your health at risk.

3 Rules for Medication Safety at Home

1. Always Read the Label Carefully

• Look for storage instructions, expiry date, and dosage guidelines
• If the label is faded or damaged, do not use the medicine

2. Check the Expiry Date Before Every Use

• Not just once, but every time you take a dose
• Don’t assume it’s safe just because you used it last month

3. Store Your Medicines Properly

• Most medicines require cool, dry conditions (15–25°C)
• Avoid placing them near windows, heaters, or in bathrooms
• Refrigerate only if the label says so

How to Check If a Medicine Is Expired

1. Look for “EXP,” “Use By,” or “Best Before” date
2. Check both outer packaging and blister strips/bottle
3. If date format is unclear (e.g., 01/26 = Jan 2026), assume the medicine expires at the end of the stated month
4. For opened liquids, creams, or eye drops – check if they have a shorter shelf life after opening (e.g., 28 days)

How to Dispose of Expired Medicines in England

• Never throw old medications in household bins or flush them down the toilet
• Take them to your local pharmacy, which will dispose of them safely under NHS protocols
• Use a medicine return scheme available at most high street pharmacies

Real-Life Example: Expired Asthma Inhaler

A 36-year-old woman used her old inhaler during a sudden asthma flare-up, only to find it barely worked. Later, it was discovered that the medication had expired over 10 months ago. The delay in effective treatment led her to the A&E.

Lesson? Always have an up-to-date, safely stored backup, and consult a pharmacist if unsure.
