Vyleesi Injection in Hong Kong: What Women and Men Should Know

Imagine a discreet self-injection that could help restore sexual desire — when you choose. That’s the promise of Vyleesi (bremelanotide), a medication officially approved in the U.S. for women with low libido. But what about men? Let’s explore its potential, availability, and cautions in Hong Kong.

For Women: Official Use

Vyleesi is approved for premenopausal women diagnosed with Hypoactive Sexual Desire Disorder (HSDD) — persistent low sexual desire that causes distress.

Mechanism: Vyleesi is a melanocortin receptor agonist, acting on brain receptors that influence sexual desire rather than directly altering hormones or blood flow.
Administration: Self-injected under the skin in the abdomen or thigh about 45 minutes before sexual activity.
Frequency: Maximum of 8 doses per month, with at least 24 hours between doses.
Reported effects: Many women experience increased sexual interest and reduced distress related to low desire.
Common side effects: Nausea, flushing, headache, dizziness, injection-site reactions, temporary increases in blood pressure, and potential skin darkening (hyperpigmentation). Women with uncontrolled hypertension or cardiovascular disease should avoid Vyleesi.
Availability in Hong Kong: As of 2025, Vyleesi is not registered in Hong Kong, so it cannot be legally obtained through local clinics or pharmacies. Attempting to import it independently carries legal and safety risks.

For Men: Experimental, Off-Label Use

Although Vyleesi is not approved for men, some researchers and clinicians have explored its potential for men with:

Erectile dysfunction
Low sexual desire
Performance anxiety

Preliminary findings: Small studies and anecdotal reports suggest some men may notice:

Improved erectile function
Increased sexual interest and satisfaction
Ability to achieve additional erections up to 18–24 hours after injection

Important caveats:

Use in men is off-label and experimental.
Safety and effectiveness for male sexual dysfunction are not fully established.
Official guidance warns against using Vyleesi to enhance sexual performance in men.

Men in Hong Kong should only consider experimental use under strict medical supervision, understanding the uncertain benefits and potential risks.

Alternatives in Hong Kong

Since Vyleesi is not legally available for women — and experimental for men — safer, legal alternatives include:

Lifestyle improvements: Exercise, stress reduction, adequate sleep, emotional well-being.
Therapy and counseling: For relationship issues, sexual anxiety, or emotional barriers to intimacy.
Medical consultation: Hormone evaluation, reviewing medications, or other approved treatments.

These approaches are safe, legally accessible, and often effective at improving sexual desire and satisfaction.

Takeaway

For women: Vyleesi is a novel, on-demand option for restoring sexual desire, but it is not yet accessible in Hong Kong.

For men: Preliminary evidence suggests potential benefits, but it is off-label and unapproved, so caution is essential.

In both cases, the safest and most effective path is professional guidance combined with lifestyle or therapeutic support. Awareness, education, and safe, evidence-based practices remain key to sexual wellness in Hong Kong.
