Dutasteride 0.5mg Capsules

What Are Dutasteride 0.5mg Capsules for Dutasteride Hair Loss?

Losing your hair can feel deeply unsettling — and if you've been researching your options, you've probably come across dutasteride. Dutasteride hair loss treatment works by targeting the hormonal root cause of male pattern baldness, rather than simply masking the problem. Dutasteride 0.5mg Capsules are a prescription-only medicine available from Cured Pharmacy following a clinical consultation. Each capsule contains 0.5mg of dutasteride as the active ingredient. If you're exploring hair loss treatments, you may also find it helpful to browse our hair care collection for complementary options.

Male pattern hair loss — medically known as androgenetic alopecia — affects a significant proportion of men in the UK, with prevalence increasing with age. Dutasteride is used off-label for this indication in the UK, though it is licensed by the MHRA for the treatment of benign prostatic hyperplasia (BPH). Its use in hair loss is supported by clinical evidence and is prescribed by healthcare professionals experienced in this area.

How Do Dutasteride 0.5mg Capsules Work for Hair Loss?

The mechanism behind dutasteride is well understood. Dihydrotestosterone (DHT) is the androgen primarily responsible for shrinking hair follicles in genetically susceptible men — a process called follicular miniaturisation. Dutasteride interrupts this process by inhibiting the enzymes that produce DHT.

• Dutasteride inhibits both type 1 and type 2 5-alpha reductase enzymes.
• These enzymes convert testosterone into DHT in the scalp, skin, and liver.
• By blocking both isoforms, dutasteride reduces serum DHT levels by approximately 90–95%.
• Lower DHT levels slow follicle miniaturisation and can allow dormant follicles to re-enter the growth (anagen) phase.
• Over time, this can result in reduced shedding and, in many men, visible improvements in hair density.

Who Should Consider Using Dutasteride 0.5mg Capsules?

Dutasteride 0.5mg Capsules are intended for adult men only. They are not suitable for women or children under any circumstances. The following groups may be considered suitable candidates, subject to a prescriber's assessment:

• Adult men experiencing androgenetic alopecia (male pattern baldness) at the crown or hairline.
• Men who have not responded adequately to finasteride 1mg after a sufficient trial period.
• Men without contraindications to 5-alpha reductase inhibitor therapy.
• Men who understand that treatment must be continued long-term to maintain results.

This is a prescription-only medicine. You must complete a clinical consultation before it can be dispensed. Men with a history of prostate cancer, liver disease, or hypersensitivity to dutasteride or other 5-alpha reductase inhibitors should not use this medicine without specialist advice.

What Is Dutasteride 0.5mg and What Is It Used For?

Dutasteride 0.5mg Capsules contain the active ingredient dutasteride, a dual 5-alpha reductase inhibitor. In the UK, dutasteride is licensed by the MHRA for the treatment of benign prostatic hyperplasia (BPH) in adult men. It is also used off-label by prescribers for the treatment of androgenetic alopecia — commonly known as male pattern hair loss. It works by reducing levels of dihydrotestosterone (DHT), the androgen responsible for progressive hair follicle miniaturisation in genetically predisposed men.

What Do You Need to Know Before Using Dutasteride 0.5mg Capsules?

Before starting dutasteride, it's essential that your prescriber is aware of your full medical history. Do not take this medicine if any of the following apply to you:

• You are a woman or a child — dutasteride is for adult men only.
• You are allergic to dutasteride, other 5-alpha reductase inhibitors, or any of the capsule excipients.
• You have severe liver impairment.
• You have a history of prostate cancer (discuss with your specialist before use).

The following medicines may interact with dutasteride. Always tell your prescriber or pharmacist about everything you are taking:

• CYP3A4 inhibitors — including ketoconazole, ritonavir, verapamil, diltiazem, cimetidine, and ciprofloxacin — may increase dutasteride plasma concentrations.
• Other medicines that affect liver enzyme activity may alter how dutasteride is metabolised.
• No clinically significant interactions have been identified with most common medicines, but always disclose your full medication list.

Important: Dutasteride is absorbed through the skin. Women who are pregnant or may become pregnant must not handle broken or crushed capsules, as dutasteride can cause abnormalities in the genitalia of a male foetus.

How Should You Use Dutasteride 0.5mg Capsules?

Always use this medicine exactly as your prescriber has told you. Do not adjust your dose without speaking to a healthcare professional first. Follow these steps each day:

1. Take one 0.5mg capsule by mouth once daily.
2. Swallow the capsule whole with a glass of water — do not chew, crush, or open it.
3. You may take it with or without food.
4. Take it at the same time each day to help you remember.
5. Continue taking it even if you do not notice immediate results — hair loss treatment requires consistent, long-term use.

What Are the Possible Side Effects of Dutasteride 0.5mg Capsules?

Like all medicines, dutasteride can cause side effects, although not everyone experiences them. Sexual side effects are the most frequently reported and are generally reversible when treatment is stopped. If you're concerned about any effects you notice, speak to your pharmacist or GP promptly. You can also explore our hair care collection for supportive products used alongside treatment.

Common side effects (may affect up to 1 in 10 people):

• Decreased libido (reduced sex drive)
• Erectile dysfunction
• Ejaculation disorders (including reduced semen volume)
• Breast tenderness or enlargement (gynaecomastia)

Less common side effects (may affect up to 1 in 100 people):

• Skin rash, itching, or urticaria
• Localised swelling (oedema)
• Testicular pain or swelling
• Mood changes, including depressed mood (reported rarely)

Dutasteride lowers PSA (prostate-specific antigen) levels by approximately 50% after 3–6 months of use. If you have a PSA test, inform your doctor that you are taking dutasteride, as this affects interpretation of results.

How Should You Store Dutasteride 0.5mg Capsules?

• Store below 30°C in a dry place, away from direct heat and sunlight.
• Keep in the original blister pack or container until use.
• Keep out of the reach and sight of children at all times.
