Zongertinib is a targeted therapeutic agent 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 medication.

How to Purchase Zongertinib

Overseas Purchase

Patients may choose to consult and purchase Zongertinib at hospital pharmacies or licensed drugstores in countries/regions where the medication has been approved for marketing.

Since drug prices may be affected by factors such as regional differences and exchange rate fluctuations, patients need to make a budget and plan 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 typically 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) (confirmation via an FDA-approved test is required).

Before purchasing, ensure the patient meets the medication eligibility criteria to avoid ineffective or incorrect medication use.

Inspect the Drug Packaging

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

Package Insert: Licensed medications are accompanied by a detailed package insert containing information such as indication, dosage and administration, and adverse reactions.

Verify Drug Information

Zongertinib tablets are yellow, oval-shaped, film-coated tablets; one side is imprinted with "L6", and the other side bears the Boehringer Ingelheim company logo.

If the color, shape, or imprint of the tablets does not match the above description, be alert to the possibility of counterfeit drugs.

Pay Attention to the Drug Source

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

Avoid purchasing through unregulated channels (e.g., unqualified websites, individual sellers) to prevent buying counterfeit or expired medications.

How to Verify the Authenticity of Zongertinib

Examine the Drug Appearance

Color and Shape: Genuine 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 Imprints: The "L6" imprint and company logo on genuine tablets should be clear and legible, with no blurring or peeling.

Verify Manufacturing Information

Manufacturer: Zongertinib is manufactured by Boehringer Ingelheim Pharmaceuticals, Inc. If the packaging indicates a different manufacturer, exercise caution.

Approval Number: Check databases of the FDA or national drug regulatory authorities (e.g., China’s National Medical Products Administration if marketed in China) to confirm whether the drug is legally registered.

Monitor Therapeutic Efficacy

When used correctly, genuine Zongertinib should produce observable therapeutic effects (e.g., tumor shrinkage or symptom relief).

If no response is observed after medication use, or if severe adverse reactions occur, seek medical attention promptly and verify the drug source.
