Osimertinib 80 mg Verification Steps
- Inspect the packaging: Check that the carton and blister packaging are intact and free from signs of tampering. Confirm the product name, strength, batch/lot number, and expiry date. Official product information identifies the batch number and expiry date as important pack details.
- Match batch and expiry details: Make sure the batch/lot number and expiry information on the outer carton correspond with the information on the inner packaging. Do not use the medicine if the packaging is damaged or appears tampered with.
- Verify with the manufacturer: Contact the pharmaceutical manufacturer or its authorized local representative using contact information from the manufacturer’s official website or product packaging. Provide the brand name, strength, batch/lot number, expiry date, and distributor information and ask whether they can authenticate the product.
- Buy from a licensed pharmacy: Obtain osimertinib only from a legitimate, licensed pharmacy or authorized medicine supplier. Osimertinib 80 mg is a prescription oncology medicine, so authentication should be treated separately from determining whether the medicine is appropriate for a particular patient.
- Ask a pharmacist or treating oncologist: If the packaging, batch information, or source seems unusual, do not rely on appearance alone. Ask a qualified pharmacist or your treating oncology team to help verify it before use.
Important: A batch number by itself does not establish that a medicine is genuine. If you suspect counterfeit or tampered osimertinib, avoid taking it until the product has been verified by an appropriate pharmaceutical professional or manufacturer.
What a batch number can and cannot prove
A printed batch number alone does not establish authenticity. Authentication should use the manufacturer’s or regulator’s documented verification system where one exists.
Suspicious products
Do not use a product if its identity, packaging integrity or supply chain is seriously in doubt. A pharmacist, healthcare professional, manufacturer or relevant medicines regulator can provide appropriate guidance.
