Eulexin is a prescription medication that contains flutamide as its sole active ingredient. Flutamide belongs to the class of non-steroidal anti-androgens and is used as part of oncology support therapy, most commonly to treat advanced prostate cancer. The medication is supplied as a 250 mg oral pill and is regulated as a prescription-only product by the Hong Kong Department of Health.
Flutamide blocks the actions of testosterone and dihydrotestosterone (DHT) by competitively binding to the androgen receptor in target tissues. By preventing these hormones from activating the receptor, flutamide reduces androgen-driven signaling that promotes the growth of prostate cancer cells.
Eulexin (flutamide) is approved in many jurisdictions, including Hong Kong, for:
The indication is based on clinical trials that demonstrated improved progression-free survival when flutamide is added to androgen-deprivation therapy.
Flutamide has been studied for several off-label indications. When used outside the approved label, it must be prescribed by a clinician who can evaluate the risk-benefit profile.
Disclaimer: Off-label use requires individualized medical supervision and a thorough assessment of potential benefits and risks.
If comprehensive interaction data for Eulexin are unavailable, patients should provide clinicians with a full medication and supplement list before initiation.
Note: Exact dosing must be individualized by the prescribing physician; the above represents a common starting point for flutamide.

Flutamide is often prescribed alongside luteinizing-hormone-releasing hormone (LHRH) agonists or surgical castration. Coordination with the oncology team is essential to avoid overlapping toxicities, especially liver-related effects.
Clinical improvement in PSA levels may be observed after several weeks of combined therapy, but individual response times vary. Continuous monitoring helps assess effectiveness.
There are no strict food bans, but taking the pill with meals reduces stomach upset. Avoid excessive alcohol, which can increase liver strain.
A mild skin rash can be a common side effect. If it spreads, becomes painful, or is accompanied by fever, contact your healthcare provider promptly as it may signal a more serious reaction.
Flutamide is primarily cleared hepatically; mild renal dysfunction generally does not require dose adjustment, but clinicians should evaluate overall organ function.
Yes, flutamide is sometimes used off-label for severe hirsutism in women, but only under close supervision because of its teratogenic potential and liver-related risks.
By blocking androgen receptors, flutamide can reduce androgenic effects such as acne, facial hair growth, and muscle bulk, while potentially increasing estrogenic activity.
Eulexin tablets are typically round, white, and embossed with “250 mg” and a brand identifier. In Hong Kong, tablet markings may vary between manufacturers.
Flutamide is not a prohibited substance by major sporting agencies, but athletes should verify with their specific governing body because anti-androgen agents can be flagged in certain panels.
Do not flush tablets down the toilet. Return unused medication to a pharmacy waste-collection program or follow the Hong Kong Department of Health’s guidelines for safe disposal.
