During the process of obtaining the medication, patients face important issues such as selecting legitimate channels, mitigating risks, and verifying authenticity.

What are the purchasing channels for Ceritinib (Zykadia)?

Overseas Purchase

Patients may consult and purchase Ceritinib from hospital pharmacies or licensed pharmacies in countries/regions where the medication is approved for marketing.

Since drug prices may be affected by factors such as regional differences and exchange rate fluctuations, patients should make adequate budgeting and planning before purchase.

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

Key Precautions for Ceritinib (Zykadia)

Strictly Adhere to Medication Guidelines

According to the package insert, patients must undergo ALK mutation testing using a fully validated detection method prior to ceritinib administration. Only patients confirmed as ALK-positive are eligible for treatment.

The recommended dosage is 450 mg orally once daily, taken with food.

Closely Monitor Adverse Reactions

Gastrointestinal Reactions: Diarrhea, nausea, vomiting, or abdominal pain occur frequently. Antiemetic and antidiarrheal medications should be administered promptly for symptomatic management.

Hepatotoxicity: Monitor liver function laboratory parameters monthly. Dose adjustment or discontinuation may be necessary if abnormalities occur.

Cardiac Issues: Monitor electrocardiograms (ECG) and electrolytes, especially in patients with heart failure or bradycardia.

Hyperglycemia: Monitor fasting blood glucose regularly before and during treatment.

Attention to Drug Interactions

Avoid concurrent use with strong CYP3A inhibitors or inducers.

If concurrent use of a strong CYP3A inhibitor is unavoidable, the ceritinib dosage should be appropriately reduced.
