Indications 

Euflex is a prescribed medication used alongside luteinizing hormone-releasing hormone (LHRH) agonists to manage advanced prostate cancer in men. 

Categorized as a nonsteroidal antiandrogen (testosterone antagonist), Euflex works by blocking the effects of androgen (a male hormone that fuels prostate cancer growth and spread), thereby impeding the proliferation and dissemination of malignant cells. 

Uses and Dosage 

Before taking Euflex and with each prescription refill, carefully review the accompanying medication guide and patient information leaflet. Seek guidance from your doctor or pharmacist if you have any inquiries or need additional information. 

Euflex dosage may vary per individual based on their medical conditions and treatment response. 

This medication is typically taken thrice daily, either with a meal or on an empty stomach. 

To achieve the best outcome, take Euflex regularly at the same times each day, exactly as prescribed by your doctor. 

Keep taking Euflex alongside the LHRH agonist treatment, even if you are feeling well. Consult your doctor before discontinuing either medication, as abrupt cessation may promote faster cancer spread.
