A Medicinal Product shall not be used beyond its expiry date why?
 
 

 


The expiration date is the final day that the manufacturer guarantees the full potency and safety of a medication. The expiration date of a drug is determined by stability testing. An expired medicine is not safe for human consumption because of the following reasons.

v Some drugs losses potency over time due to degradation, and become less effective at treating the intended condition (i.e in an expired medication, the drug has limited or no therapeutic effect).

vOn expiration, the active pharmaceutical ingredient of the medicinal product starts degrading and the degradation product (impurity) may be more toxic than parent product, which can create harmful effects in patients.
