Zongertinib is a targeted therapeutic drug for non-small cell lung cancer (NSCLC) harboring activating mutations in the tyrosine kinase domain of HER2 (ERBB2). Due to its specificity and potential efficacy, extra caution is required when purchasing this drug.

How to Purchase Zongertinib

Overseas Purchase

Patients may choose to consult and purchase Zongertinib at hospital pharmacies or licensed pharmacies in countries/regions where the drug has been launched.

Since drug prices may be affected by factors such as regional differences and exchange rate fluctuations, patients need to make budgetary plans in advance before purchasing.

Purchase via Medical Service Institutions

Patients may consult domestic overseas medical service institutions that cooperate with international pharmacies or pharmaceutical companies.

These institutions can usually provide legal import channels and offer professional consultation and guidance.

Precautions for Purchasing Zongertinib

Confirm the Indication

Zongertinib is indicated for adult patients with non-squamous non-small cell lung cancer (NSCLC) whose tumors harbor activating mutations in the tyrosine kinase domain of HER2 (ERBB2) (confirmed by an FDA-approved test).

Before purchase, it is necessary to ensure that the patient meets the medication eligibility criteria to avoid ineffective or incorrect medication use.

Inspect the Drug Packaging

Outer Packaging: The packaging of authentic Zongertinib should be intact, with no signs of damage or tampering. It should clearly indicate the drug name, dosage (e.g., 60mg), production batch number, expiration date, and other relevant information.

Drug Instruction Leaflet: Legitimate drugs are accompanied by a detailed instruction leaflet containing information such as indications, dosage and administration, and adverse reactions.

Verify Drug Information

Zongertinib tablets are yellow, oval, film-coated tablets, with "L6" printed on one side and the Boehringer Ingelheim company logo on the other side.

If the color, shape, or markings of the tablets do not match the above description, the possibility of counterfeit drugs should be suspected.

Pay Attention to the Drug Source

When purchasing, patients should request the seller to provide the drug’s import approval certificate or legal sales certificate.

Avoid purchasing through unregulated channels (such as unqualified websites or individual sellers) to prevent buying counterfeit or expired drugs.

How to Identify Authentic Zongertinib

Observe the Drug Appearance

Color and Shape: Authentic Zongertinib tablets are yellow and oval. If the tablets show abnormal colors (e.g., white, brown) or irregular shapes, they may be counterfeit.

Clarity of Markings: The "L6" and company logo on authentic tablets should be clearly visible, with no blurring or peeling.

Verify Production Information

Manufacturer: Zongertinib is manufactured by Boehringer Ingelheim Pharmaceuticals, Inc. If the packaging indicates another manufacturer, vigilance is required.

Approval Number: The drug’s legal registration status can be verified by checking databases of the FDA or national drug regulatory authorities (e.g., if launched in China).

Observe Therapeutic Efficacy

After proper administration of authentic Zongertinib, certain therapeutic effects (such as tumor shrinkage or symptom relief) should be observable.

If there is no response to the medication or severe adverse reactions occur after use, patients should seek medical attention promptly and verify the drug source.
