The burden of ensuring that lot number and expiry date of drug product are indicated on the invoice covering the sales/transaction of said drug product shall rest on both the drug outlet and the drug distributor/supplier, and drug distributor/supplier and the manufacturer or importer, as the case may be.

The drug outlet, drug distributor/supplier and manufacturer are therefore liable for the failure to indicate the lot number and expiry date on a given invoice covering the drug products delivered, unless the drug distributor or manufacturer can prove by substantial evidence that the invoice subject to question is spurious and/or was not issued by the same distributor/manufacturer.

For the information of all concerned.
