“It expired last month… can I still take it?”
This is one of the most common questions heard in pharmacies and homes alike. Many people assume that medicines become instantly dangerous the moment they cross the expiry date. Others believe expiry dates don’t matter at all.
The truth lies somewhere in between.
What Does the Expiry Date Actually Mean?
The expiry date is the last day the manufacturer guarantees that the medicine will:
•Maintain full potency
•Remain chemically stable
•Be safe when stored as recommended
After this date, the company no longer assures the drug’s effectiveness or safety.
Important: It does not always mean the medicine becomes toxic the next day.
What Changes After Expiry?
Over time, medicines may undergo:
Loss of potency – the most common issue
Chemical degradation
Reduced therapeutic effect
Physical changes (color, odor, texture)
Risk of contamination (especially liquids)
In many cases, the medicine simply becomes weaker — but that can still be risky.Certain medicines should never be used after expiry:
Liquid antibiotics
Insulin
Eye drops
Nitroglycerin tablets
Reconstituted syrups
Biologics and vaccines
These products are more sensitive to degradation or contamination.
Real-World Risks of Using Expired Medicines
Using expired drugs may lead to:
•Treatment failure
•Worsening infection
•Poor chronic disease control
•Unexpected side effects
•Delayed proper treatment
For critical conditions, even small potency loss can matter.
