Is Finasteride Safe? What Singaporean Men Need to Know

For many Singaporean men, balding is not just a cosmetic issue; it affects self-confidence, social life, and even career opportunities. That’s the reason treatments like finasteride became so popular. But with all prescription drugs comes the same question: Is finasteride safe?

In this article, we’ll break down what the science says about finasteride, how safe it is for long-term use, and why choosing a licensed provider like Sire is the smartest way to start treatment in Singapore.

What is Finasteride?

Finasteride (also known as the branded product Propecia) is a prescription pill that blocks DHT, the hormone responsible for male pattern baldness. By blocking DHT, finasteride stops loss of hair and induces regrowth.  

Finasteride has been regulated in Singapore since the late 1990s by the Health Sciences Authority (HSA). It is lawful, safe, but only available from registered doctors by prescription. You are not able to purchase it over the counter from.

At Sire, you can consult privately online with an MOH-licensed doctor and, if prescribed, have finasteride delivered to your doorstep.

How Effective Is Finasteride?

When considering safety, it helps to weigh it against results. Research shows:

90% of men lose no additional hair with daily treatment.

60–65% of men notice visible regrowth within 6–12 months.

Results become noticeable within 3–6 months, with best results at the 12-month mark.

As opposed to herbal shampoos or so-called “natural” tonics, finasteride is evidence-based. It’s one of only two FDA- and HSA-approved treatments for male pattern baldness, minoxidil being the other.

Typical Side Effects (and What the Numbers Really Are)

Most men avoid finasteride  because of side effects. Here’s what actually happens:

Sexual side effects (reduced libido, softer erections, or reduced semen volume): happen in 1–2% of men.

Other minor effects: headache, dizziness, or rash.

Rare effects: testicular pain (fewer than 1 in 1,000 cases).

The reality? Over 98% of men have no significant issues. And for those who do, side effects usually go away after stopping the medication.

At Sire, your doctor will discuss these openly and monitor your progress so you’re never left guessing.

Is Finasteride Safe for Long-Term Use?

Yes. Global research shows that men have taken finasteride daily for more than 10 years with no new safety concerns.

No indication of organ damage or faint long-term hazards.

Reversible effects when treatment stops (hair loss gradually returns).

Fertility and Finasteride: Should You Be Concerned?

Many Singaporean men question whether finasteride affects sperm. 

The evidence is as follows:

Studies, including research by Samplaski and colleagues (2013) and NHS guidance (2024), suggest that finasteride may temporarily reduce sperm count or motility in some men.

These changes are typically short-term and return to normal once the medication is discontinued.

For most healthy men, the overall risk to fertility is considered very low.

Doctor’s’ advice:

Avoid donating blood during finasteride.

Use protection if pregnant

Mental Health Considerations

Finasteride has also been studied for possible mood effects:

Some men get depressed or in a low mood.

In 2022, product labels were revised by the HSA to include warnings for unusual mood change (see HSA Safety Alert: Finasteride and potential risk of suicidal ideation)

Most men have no psychological effect.

What About Post-Finasteride Syndrome?

A controversial condition called Post-Finasteride Syndrome (PFS) suggests some men may have ongoing side effects after stopping.

Regulators, including the HSA, have acknowledged reports but stress it is very rare – see HSA Safety Alert: Finasteride and Suicidality and Psychological Adverse Events

More research is needed to confirm whether PFS is a true condition.

The takeaway: rare risks exist, but finasteride is safely taken by most men under physicians’ care.

Myths About Finasteride in Singapore

“It makes you impotent forever.” → False. Side effects, if any, usually resolve after stopping.

“Natural remedies are safer.” → Herbal shampoos are not tested clinically. Finasteride is.

“Once you start, you can never stop.” → Misleading. Stopping only reverses balding to baseline no “worse rebound.”

Who Should Not Use Finasteride?

Finasteride is suitable for most men in Singapore, but it is not suitable for all. Doctors usually do not prescribe finasteride if you are in the following groups:

Under the age of 18 years: Male pattern hair loss treatment is not indicated at this age, since hair loss may be due to other reasons as well.

Men with liver disease: As finasteride is metabolised in the liver, men with liver disease may need to undergo extra testing or monitoring.

Those taking certain prostate medicines: If you are already taking medication for enlarged prostate, your doctor will have to monitor for possible interactions.

This is the reason why it is risky to self-medicate from unregulated internet sites. You cannot be sure that finasteride is the right treatment for you without being assessed by a doctor. At Sire, all prescriptions are only issued after a discreet online consultation with an MOH-licensed doctor. That way, you can be confident finasteride is right for your unique health profile,  giving you effective results and peace of mind.
