How long can Cetirizine be used after expiry date?

Cetirizine, like many medications, can lose potency after its expiration date, which is typically about 1-2 years after manufacturing. While some medications may still be effective for a short period beyond the expiry date, it's generally not recommended to use them past that date due to potential decreased efficacy and safety concerns. Always consult a healthcare professional for advice on medication use, especially regarding expired products.
