About the medicine

What it is and how it works

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.

Who it is for

  • Authorised in the EU for an enlarged prostate; hair-loss use is off-label.
  • One 0.5 mg capsule swallowed whole once a day, with or without food.

Safety summary

Sexual side effects are common and may continue after you stop the capsules.

How is dutasteride different from finasteride?
Dutasteride inhibits both 5-alpha-reductase isoforms (I and II), while finasteride only acts on II. DHT blockade is more complete, which can translate into better response in some patients.
It is typically considered when finasteride has not given a sufficient response after 6–12 months, or when the pattern of loss is particularly aggressive. It is off-label for alopecia in some countries, so the doctor weighs it case-by-case.
More questions
Similar to finasteride, with a slightly higher incidence of reduced libido or reduced ejaculatory volume in some studies. The doctor reviews benefits and risks with you before prescribing.
Yes, under medical supervision. The switch is weighed after reviewing prior response, tolerance and your goals. It is paired with a quarterly follow-up plan.
In one 917-man, 24-week trial, dutasteride 0.5 mg increased crown hair count by 89.6 hairs, against 56.5 hairs on finasteride 1 mg and a loss of 4.9 hairs on placebo, a difference the authors reported as statistically significant. That is a single six-month trial measuring one part of the scalp, and it does not make dutasteride the right choice for any particular person. Dutasteride is also off-label for hair loss across the EU, while finasteride 1 mg is authorised for it. Your prescriber weighs both.
Longer than most medicines. At the usual 0.5 mg daily dose the half-life is about three to five weeks, and the FDA label puts the terminal half-life at roughly five weeks at steady state. Serum concentrations can still be detected for four to six months after the last dose. That is why the label says not to donate blood until at least six months have passed since your last capsule, so that dutasteride cannot reach a pregnant woman through a transfusion.
Yes, but only off-label, and only if the prescriber judges it appropriate for you. Across the EU, dutasteride 0.5 mg is authorised for benign prostatic hyperplasia, meaning an enlarged prostate. It is separately approved for androgenetic alopecia in men in South Korea, since 2009, and in Japan, where the regulator approved it in 2015 at a starting dose of 0.1 mg daily. A European doctor prescribing it for hair loss is working outside the licensed indication and should tell you so.
Write to your doctor in the private chat in your account: describe what you notice and when it started. The doctor can adjust the plan, pause it or suggest another option. If you have severe symptoms such as difficulty breathing, swelling of the face or chest pain, call 112 or go to an emergency department straight away.
It depends on what you take. List every medicine, supplement and herbal product in the questionnaire, including ones you use only occasionally. The doctor checks for interactions before prescribing, and your pharmacist checks again when you collect Dutasteride 0.5mg.
The doctor can consider another hair-loss treatment, a different form (tablet or solution) or a combination, depending on your pattern of loss and history. Some cases, such as sudden or patchy hair loss, need an in-person dermatologist, and the doctor tells you so.
You can message your doctor in the private chat at any time. Hair treatments take months to show an effect, so the doctor reviews progress and tolerance at each renewal, often with new scalp photos, and adjusts the plan if needed.
Yes. Hi-Doctor runs 100 % online across the EU, so if you live in Limerick you can fill in the questionnaire and receive the medical review without travelling. The electronic prescription issued by the licensed doctor is valid in any EU pharmacy under Directive 2011/24/EU; outside Spain, the pharmacist dispenses the locally marketed equivalent of the same active ingredient.
Through the pattern of loss, how long it has been progressing, family history and current medication. In some cases we ask for scalp photos. The doctor proposes a tailored treatment plan and adjusts it to your tolerance.
The private electronic prescription (Receta Médica Privada Electrónica) is issued by a licensed doctor in Spain. It is a PDF carrying every field required by EU Directive 2011/24/EU (patient, prescriber with country of registration, active ingredient, dose), which makes it legally recognised across all 27 EU member states. In Spanish pharmacies it is dispensed from the QR; outside Spain, the pharmacist dispenses the locally marketed equivalent of the same active ingredient.

Medicine information and safety

How does Dutasteride 0.5mg work?

DHT shrinks scalp hair follicles. Testosterone is turned into a stronger hormone, dihydrotestosterone or DHT, by an enzyme called 5-alpha-reductase. In men with male pattern hair loss, the balding scalp carries miniaturised follicles and higher amounts of DHT, so each follicle grows a thinner, shorter hair.

Dutasteride blocks both enzyme types. Dutasteride inhibits both the type 1 and the type 2 forms of 5-alpha-reductase. Finasteride inhibits only the type 2 form. Blocking both routes means less testosterone is converted overall, which is why blood DHT falls further on dutasteride than on a type 2 blocker alone.

Less DHT reaches the follicle. With less DHT circulating, the shrinking process slows and some follicles can go back to producing thicker hair. In men treated for an enlarged prostate, which is the EU-authorised use, median blood DHT fell by 94 percent at one year. Any scalp effect builds over months.

How to use Dutasteride 0.5mg

Get a prescriber's decision first. Dutasteride is prescription-only everywhere in the EU. Because using it for hair loss is off-label here, a doctor has to weigh the benefits and risks with you, and can decide it is not appropriate.

Swallow one capsule whole daily. The dose is one 0.5 mg soft capsule by mouth once a day. Swallow it whole. Do not chew it or open it, because contact with the contents can irritate the mouth and throat.

Take it with or without food. Food does not change how much dutasteride your body absorbs, so choose a time you will remember and keep to it. Blood levels reach about 90 percent of steady state after three months.

Keep capsules away from others. Dutasteride passes through skin. Women who are or could become pregnant, children and adolescents must not handle leaking capsules. If contact happens, wash the area straight away with soap and water.

Use a condom if needed. Small amounts of dutasteride reach semen. If your partner is pregnant or might become pregnant, the label advises using a condom, because the medicine can affect how a male foetus develops.

Do not donate blood. Do not give blood until at least six months have passed since your last dose. The wait exists so that dutasteride in donated blood cannot reach a pregnant woman receiving a transfusion.

Flag it before a PSA test. Dutasteride roughly halves the PSA blood test used to look for prostate cancer, within three to six months. Tell any doctor who orders a PSA that you take it, so the result is read correctly.

Give it several months. For the licensed prostate use the label says a response can take up to six months. In the hair-loss trial the main result was measured at week 24, so judge it slowly and with your prescriber.

Common side effects

Stop and get urgent medical help if (seek medical help immediately): Swelling of the face, lips, tongue or throat, or difficulty breathing, Sudden widespread rash, hives or intense itching after a dose, A new breast lump, breast pain, or discharge from a nipple, Breathlessness, unusual tiredness, or swelling of the ankles and legs, Thoughts of harming yourself, or a low mood that will not lift, Pain and swelling in a testicle that does not settle

Most people who get side effects get these (common (≥1/100 to <1/10)): Trouble getting or keeping an erection, reported by 6.0 percent in year one, Lower sex drive, reported by 3.7 percent in year one, Difficulty ejaculating, including less semen, reported by 1.8 percent in year one, Breast enlargement or tenderness, reported by 1.3 percent in both years, Sexual side effects that may continue after you stop the medicine, Dizziness, mainly when dutasteride is taken together with tamsulosin

Less common, or frequency not known (uncommon (≥1/1,000 to <1/100)): Loss of body hair, or unwanted extra hair growth elsewhere, Heart failure, reported mainly when dutasteride is combined with tamsulosin, Depression and low mood, reported after marketing, frequency not known, Pain and swelling in the testicles, frequency not known, Allergic reactions with rash, itching, hives or swelling, frequency not known, Reduced sperm count, semen volume and sperm motility in healthy men, Male breast cancer, reported rarely in trials and after marketing

Do not use Dutasteride 0.5mg if

  • You are a woman, a child or an adolescent
  • You are pregnant, could become pregnant, or are breastfeeding
  • You have ever reacted badly to dutasteride or another 5-alpha-reductase inhibitor such as finasteride
  • You are allergic to soya or peanut, because the capsule contains lecithin that may contain soya oil
  • You have severe liver impairment
  • You plan to donate blood within the next six months
  • You and your partner are trying to conceive, since dutasteride can reduce sperm count and motility
  • You have not had the prostate examination and PSA test the label requires before starting
  • You cannot swallow a capsule whole, because it must never be chewed or opened

Medicines and substances that interact

  • Strong CYP3A4 blockers (ritonavir, indinavir, nefazodone, itraconazole, oral ketoconazole): Can raise dutasteride blood levels, and the already long half-life may be prolonged further. Prescriber may reduce how often you take dutasteride if side effects appear.
  • Verapamil or diltiazem (heart and blood-pressure medicines): Dutasteride levels averaged 1.6 to 1.8 times higher in patients also taking these. Prescriber notes the higher exposure and reviews you if side effects appear.
  • Alpha-blockers such as tamsulosin: The combination raised ejaculation problems and dizziness, and cardiac failure was marginally higher. Prescriber combines them only after a careful benefit and risk assessment.
  • PSA blood test for prostate cancer: Dutasteride lowers mean PSA by about 50 percent, so older results no longer compare. Prescriber sets a new PSA baseline at six months and tracks changes from it.
  • Warfarin and digoxin: Dutasteride had no effect on how the body handles either medicine in studies. No dose change needed, though the prescriber still reviews your full medicine list.
  • Colestyramine (cholesterol-lowering powder): 12 g taken one hour after a dutasteride dose did not change its levels. No change to dose or timing is needed on the basis of this study.
