Can I get it?
Not for this use. Dutasteride 0.5mg has no EU authorisation for it, so it cannot be prescribed or dispensed here for that purpose.

IN PLAIN TERMS
What Dutasteride 0.5mg is, and how to get treatment
Dutasteride is a daily capsule that lowers DHT, the hormone involved in male pattern hair loss, and it blocks both forms of the enzyme that makes it. In the EU it is authorised only for an enlarged prostate, not for hair loss: using it for hair loss in Europe is off-label, meaning a doctor prescribes it outside the use the medicine was licensed for. It has been approved specifically for male pattern hair loss in South Korea and Japan, but no European regulator has assessed it for that purpose. Its known side effects, measured in prostate studies in older men, include reduced erections in about 6 in 100 men in the first year, lower sex drive in about 4 in 100, and breast tenderness or swelling in about 1 in 100, and the EU product information notes these sexual effects can persist after stopping.
Dutasteride 0.5mg has no EU marketing authorisation for this use. It may be an approved medicine for something else, or approved in another country — but not something a doctor here can prescribe for this.
What can I take instead?
Finasteride is approved in the EU, has published peer-reviewed trial results, and can be prescribed today if a doctor decides it suits you.

Peer-reviewed
Gubelin Harcha W, Barboza Martinez J, Tsai TF, et al. A randomized, active- and placebo-controlled study of the efficacy and safety of different doses of dutasteride versus placebo and finasteride in the treatment of male subjects with androgenetic alopecia. J Am Acad Dermatol. 2014;70(3):489-498.e3. doi:10.1016/j.jaad.2013.10.049 (PMID 24411083)| DOSE OR GROUP | MEAN WEIGHT CHANGE | WEEKS |

| dutasteride 0.1 mg daily | +63.0 hairs (same measure) | 24 |
| dutasteride 0.02 mg daily | +17.1 hairs (same measure) | 24 |
| finasteride 1 mg daily (active comparator arm) | +56.5 hairs (same measure) | 24 |
| placebo | -4.9 hairs (same measure) | 24 |
This 24-week study was run entirely outside the EU and was never submitted to support an EU marketing authorisation for hair loss, so no EU regulator has assessed dutasteride for this indication and no long-term hair-loss outcome data exist.

NAMED SAFETY SIGNALS
What has been reported with Dutasteride 0.5mg.
Impotence
Reported in 6.0% of men in year 1 (n=2,167) and 1.7% in year 2 (n=1,744) of the placebo-controlled phase III programme. These figures come from prostate trials in older men taking dutasteride 0.5 mg, not from hair-loss trials.
Decreased libido
Reported in 3.7% of men in year 1 and 0.6% in year 2 of the same prostate trials.
Ejaculation disorders, including reduced semen volume
Reported in 1.8% of men in year 1 and 0.5% in year 2 of the same prostate trials.
Breast disorders (tenderness and enlargement)
Reported in 1.3% of men in year 1 and 1.3% in year 2 of the same prostate trials.
Sexual effects that persist after stopping
The EU product information states that these sexual adverse events are associated with dutasteride treatment, that they may persist after treatment is stopped, and that the role of dutasteride in that persistence is not known.
Depression and mood changes
Depression is listed with frequency not known. Following the EU Article 31 review concluded in 2025, information about the mood changes seen with finasteride is being added to dutasteride product information as a precaution, because dutasteride works in the same way; a direct link between dutasteride and suicidal ideation was not established.
Body hair loss and hypertrichosis
Alopecia (mainly loss of body hair) and hypertrichosis are listed as uncommon in the EU product information.

About
What is Dutasteride 0.5mg?
Active ingredient: Dutasteride · Dosages: 0.5 mg / day
Dutasteride inhibits both isoforms of 5-alpha-reductase (I and II), while finasteride only acts on type II. The DHT blockade is more complete, which can translate into a better response in some patients.
It's typically considered when finasteride hasn't given a sufficient response after 6–12 months, or when the pattern of loss is particularly aggressive. It's off-label for alopecia in some countries, so the doctor weighs it case by case.
How it works in the body
By inhibiting both 5-alpha-reductase isoforms, dutasteride lowers scalp DHT more completely than finasteride — slowing follicle miniaturisation where a single-isoform block wasn't enough.
How it helps
How it protects your hair.
More complete DHT block
Acts on both enzyme isoforms, not just one.
A step-up option
Considered after 6–12 months of insufficient response to finasteride.
Case-by-case decision
Off-label for alopecia in some countries — the doctor weighs benefits and risks with you.
What to expect
A steady, monitored routine.
One 0.5 mg capsule daily, assessed over months. Switching from finasteride is done under medical supervision with a quarterly follow-up plan.
- Months 1–3 · Daily 0.5 mg; changes build silently
- Months 3–6 · Shedding stabilises
- Months 6–12 · Visible improvement is assessed
- Ongoing · Quarterly follow-up reviews
Doses your doctor can prescribe
- Standard dose0.5 mg / day
Your schedule is personal
These are typical steps only. Your doctor adjusts the plan to how you respond and tolerate it — and you can message them at any point.
Safety first
Safety, in full.
Dutasteride 0.5mg is an effective medicine — and like any medicine it carries risks. Your doctor screens for all of this before prescribing. Here's the honest picture, not just reassurance.
Adult men with androgenetic alopecia, often after an inadequate finasteride response, or for benign prostatic hyperplasia.
- 0.5 mg orally once a day, with or without food.
- Half-life is long (3–5 weeks): plasma levels persist after stopping, side effects can take time to resolve.
- Stopping treatment reverses hair-loss gains over 6–12 months.
Who should not take it
- Women, especially during pregnancy or planning pregnancy — dutasteride causes feminisation of male foetuses and is absorbed through the skin.
- Children and adolescents under 18.
- Known hypersensitivity to dutasteride or other 5α-reductase inhibitors.
- Severe liver impairment.
