Why Ignoring Expiry Dates Can Be Dangerous

What Does "Expiry Date" Mean?

The expiry date is the time until which a medicine is guaranteed to be safe and effective when stored properly.

After this date:

• The drug may lose potency

• Chemical composition may change

• Safety cannot be guaranteed

This is especially important for sensitive formulations.

What Happens If You Use Expired Medicines?

1. Reduced Effectiveness

Over time, active ingredients break down.

2. Risk of Unsafe Degradation

Some medicines may chemically degrade into harmful compounds.

While not all expired drugs become toxic, the risk becomes unpredictable.

3. Treatment Failure

If a medicine doesn’t work as expected, it can delay proper treatment.

This is especially dangerous in:

• Infections

• Diabetes

• Emergency conditions

Medicines Where Expiry Is Very Important

Some medicines should never be used after expiry, including:

• Eye Drops

Once opened, eye drops can get contaminated. Most should be discarded within 4 weeks of opening, even if not expired.

• Syrups and Suspensions

Liquid medicines degrade faster than tablets. Antibiotic suspensions are especially unstable.

• Insulin

Insulin is temperature-sensitive and loses potency easily. Expired insulin may fail to control blood sugar.

• Reconstituted Medicines

Any medicine mixed with water (like dry syrups) has a shorter shelf life.
