Description

Dutasteride 0.05% in Trichosol — Product description

The problem with hair loss

Hair loss is easy to dismiss — until it happens to you. The visible signs are familiar: thinning at the crown, a wider parting, a hairline moving in the wrong direction. The less visible impact is often harder to carry. Confidence drops. Self-consciousness builds. The worry that things are getting worse — and that nothing tried so far has made a real difference — becomes part of daily life.

The problem with standard treatments

For many people, the frustration goes beyond the hair loss itself. It is about the experience of trying to treat it.

Standard topical liquids sting on application. The alcohol hits the scalp before the product has had a chance to absorb. The propylene glycol leaves a tight, uncomfortable residue for hours afterwards. After a few weeks of that, skipping a night starts to feel like a reasonable decision.

Skipping nights is exactly what stops hair loss treatment from working.

Why a single-ingredient approach?

Not every patient needs a multi-ingredient formula from the outset. Some want to start with dutasteride alone — targeting the hormonal driver of hair loss directly, before considering whether to add minoxidil or tretinoin later. Others have been prescribed this formula specifically because clinical assessment or TrichoTest results indicate that dutasteride alone is the most appropriate starting approach for their individual profile.

A single-ingredient compounded solution is not a lesser option. It is a considered one.

Why a gentle base matters

The Trichosol base removes propylene glycol and alcohol from the equation entirely. No stinging. No tight, dry scalp after application. No alcohol smell. Just the active ingredient, delivered in a vehicle the scalp is far more likely to accept comfortably — night after night, for as long as treatment is needed.

Why 0.05% dutasteride?

The dutasteride concentration in this formula is 0.05%. This is the lowest available compounded strength. The prescriber selects it when clinical assessment indicates this is the most appropriate starting or ongoing concentration.

For some patients it is a cautious entry point into dutasteride treatment. For others it reflects a TrichoTest result suggesting a lower anti-androgen requirement. For others still, it is simply the right ongoing concentration based on their individual response and tolerability.

Starting at 0.05% is not starting weak. It is starting right for you.

A medically responsible route

At Courier Pharmacy, treatment starts with a proper assessment. Suitability is checked. The decision to prescribe this compounded solution is a clinical one — based on your scalp, your history, and your goals.

What is the Dutasteride 0.05% in Trichosol (propylene glycol and alcohol FREE) topical hair loss solution?

This compounded topical hair loss solution contains dutasteride 0.05% in a Trichosol base that is completely free from propylene glycol and alcohol. It is designed for adults with pattern hair loss who want a targeted, single-ingredient approach — particularly those who are new to dutasteride, stepping into compounded treatment for the first time, or who need a gentler base because standard topical products have caused irritation. The aim is straightforward: address the hormonal driver behind hair loss at the lowest available dutasteride concentration, in a base the scalp can actually tolerate.

Courierpharmacy.co.uk divider

  • Single active ingredient targeting the root hormonal cause of pattern hair loss
  • Propylene glycol free, alcohol free Trichosol base for a more comfortable daily experience
  • Dutasteride at 0.05% — the lowest available concentration, suitable for those starting compounded dutasteride treatment
  • May suit people with androgenetic alopecia whose scalps have reacted to standard topical bases
  • Safe prescribing still matters — hair loss treatment needs proper screening, review, and follow-up
  • Part of the Gro hair loss range, designed for personalised treatment at less than £1 per day

Pattern hair loss is personal

Pattern hair loss is common, but that does not make it any less personal. Many people first notice extra shedding, reduced density, or a hairline that seems to be quietly moving backwards. Many then try a product that does not match their biology, see little result, and quietly give up — not because treatment cannot work, but because they were never on the right treatment to begin with.

Courierpharmacy.co.uk divider

A formula for people who need a gentler, focused start

This Trichosol solution is aimed at people who want a carefully considered, single-ingredient approach to targeting the hormonal driver of hair loss — in a base their scalp can genuinely tolerate. It is particularly relevant for those starting compounded dutasteride treatment for the first time, those whose prescriber has identified 0.05% as the most appropriate clinical concentration, and those who have previously reacted to alcohol or propylene glycol-based products.

Courierpharmacy.co.uk divider

The goal of treatment

Hair loss affects more than appearance. It chips away at confidence. It makes ordinary moments feel oddly loaded — a harsh bathroom mirror, a photo taken from an unexpected angle, a windy day when you would rather not think about what is visible.

The goal of treatment is not perfection. It is to slow loss, support healthier growth, and help you feel more in control — with a plan that makes clinical sense and a base that makes daily use something you can actually stick to.

Courierpharmacy.co.uk divider

Why compounding?

What compounding means

Compounding means a medicine is prepared to order by a licensed pharmacy for an individual patient. It is not a mass-produced one-size-fits-all product. In the UK, this sits within a regulated framework and should only be supplied when clinically appropriate.

Courierpharmacy.co.uk divider

Why compounding matters for this formula

Some people choose a compounded solution because the concentration they need — such as 0.05% dutasteride — does not exist in any standard licensed product. Others come to compounding because standard topical bases have caused irritation and they need the active ingredient delivered in a gentler vehicle. Others want the clinical flexibility to start with a single ingredient and build their formula over time as their treatment plan evolves.

The Trichosol base addresses the tolerability concern directly. It removes both propylene glycol and alcohol — the two most common causes of topical scalp irritation — without reducing the effectiveness of the active ingredient.

Courierpharmacy.co.uk divider

Personalised medicine in practice

Hair loss is not identical from one person to the next. The right dutasteride concentration for one patient is not the right concentration for another, and the right number of ingredients at one stage of treatment may not be right at another. Compounding makes it possible to prescribe 0.05% dutasteride alone — a strength and formulation that simply does not exist in any standard licensed product — when clinical assessment indicates that this is the most appropriate approach. The medicine is shaped around the patient, not the other way around.

Courierpharmacy.co.uk divider

The Trichosol advantage

When the vehicle is the problem

For patients who have reacted badly to standard topical solutions, the problem is not always the active ingredients. Often it is the vehicle carrying them. Alcohol causes stinging on application and dries the scalp significantly over time. Propylene glycol is a common cause of contact irritation, particularly in patients with already sensitive or reactive scalps.

Courierpharmacy.co.uk divider

What Trichosol removes

The Trichosol base removes both of these excipients entirely. The result is a solution that absorbs without stinging, does not dry the scalp, and does not leave the tight or uncomfortable residue that causes so many people to abandon their routine. The active ingredient is unchanged. Only the vehicle is different — and sometimes that difference is everything.

Courierpharmacy.co.uk divider

Why tolerability drives outcomes

A treatment only works if you use it consistently. If the daily experience of applying it is uncomfortable, consistency breaks down. The Trichosol base exists to remove that barrier — making it possible to maintain the kind of steady, sustained daily routine that hair loss treatment requires.

Courierpharmacy.co.uk divider

TrichoTest: personalising the approach

TrichoTest reduces guesswork. It is a pharmacogenetic test that analyses 26 genetic polymorphisms linked to nine key treatment pathways relevant to hair loss. Rather than prescribing from standard protocols alone, TrichoTest combines your genetic profile with your medical history to predict which ingredients, dosages, and delivery methods are most likely to work for your biology.

Courierpharmacy.co.uk divider

How the TrichoTest informs the 0.05% dutasteride concentration

The 0.05% dutasteride concentration is one area where TrichoTest is particularly valuable. Some patients have genetic profiles that suggest a lower anti-androgen requirement — meaning 0.05% may be as effective for them as a higher concentration would be for someone else. TrichoTest can identify this before treatment begins, helping the prescriber choose the right starting strength from the outset rather than adjusting after months of treatment.

Courierpharmacy.co.uk divider

How the TrichoTest informs this formula

If TrichoTest identifies a moderate or lower response to anti-androgens, the prescriber may determine that dutasteride 0.05% alone is the most clinically appropriate starting combination — before deciding whether additional ingredients are indicated.

If the test reveals factors that would make a combination formula more beneficial from the outset — such as poor minoxidil response or low collagen synthesis capacity — the prescriber may recommend a multi-ingredient formula instead, or plan to expand this one over time.

Courierpharmacy.co.uk divider

The nine pathways TrichoTest analyses

  • Prostaglandins and sulphotransferase — how you process minoxidil and latanoprost
  • Anti-inflammatory response — your reaction to glucocorticoids and immunomodulators
  • Anti-androgen metabolism — how effectively you respond to dutasteride, finasteride, and 17?-oestradiol
  • Circulation stimulation — response to vasodilators
  • Collagen synthesis capacity
  • Insulin-like Growth Factor (IGF-1) response
  • Vitamin absorption — A, B7, B9, B12, C, D, E
  • Mineral absorption — zinc, magnesium, iron, selenium
  • Antioxidant needs and oxidative stress profile

Courierpharmacy.co.uk divider

Beyond ingredient selection

TrichoTest also identifies nutritional gaps and metabolic factors that affect hair health independently of topical treatment. If genetic variants reduce zinc or iron absorption, the prescriber can recommend targeted supplementation alongside this Trichosol formula — moving treatment from guesswork towards something shaped by your actual biology.

TrichoTest does not guarantee results, but it gives the prescriber better information to decide whether this specific formula — at this specific dutasteride concentration, in this specific base — is right for you, or whether something different would serve you better.

The Gro hair loss range

What is the Gro brand?

Gro is the compounded hair loss range created by Courier Pharmacy and Medical Mojo. It exists because hair loss treatment should not feel one-size-fits-all.

Some people want a traditional liquid spray — direct, efficient, and familiar. Some prefer a foam. Others need an alcohol-free and propylene glycol-free base because their scalp reacts to standard excipients. Gro brings those options together under one brand, matching treatment to the person using it, not the other way around.

Each Gro product comes in a 30ml bottle designed to last one month. Every option costs £29.99 for up to three active ingredients — less than £1 a day.

Courierpharmacy.co.uk divider

Why Gro is different

Gro was built around three practical goals:

  • Choice of formulation: topical liquid, topical foam, or Trichosol solution (propylene glycol free and alcohol free)
  • Personalisation: single, dual, and triple-ingredient combinations across multiple concentrations
  • Better tolerability: every format is designed to reduce the friction that stops people from maintaining their routine

The three formulation types

  1. Topical hair loss liquid — a traditional spray solution containing alcohol and propylene glycol. Well-established, with efficient scalp penetration. Chosen by patients who want a direct, familiar format.
  2. Hair loss foam — lighter, faster-drying, and easier to apply without dripping. Chosen by patients who want clinical results without the mess or residue of a liquid.
  3. Trichosol topical solution — propylene glycol free and alcohol free. Designed for patients with sensitive or reactive scalps who need a gentler base. This is the formulation described on this page.

Courierpharmacy.co.uk divider

Ingredients used across the Gro range

Depending on the product selected, Gro formulations may include:

  • Dutasteride
  • Finasteride
  • Minoxidil 5%
  • Tretinoin 0.01%

These can be prescribed alone or in combination, and at varying concentrations, depending on the individual treatment plan.

Dutasteride 0.05% in Trichosol — Active ingredient

Dutasteride 0.05%

Dutasteride is a 5-alpha reductase inhibitor. It reduces the conversion of testosterone to dihydrotestosterone, or DHT — the key hormonal driver of androgenetic alopecia in susceptible hair follicles. At 0.05%, this is the lowest available compounded concentration. It reflects a clinical decision that this is the most appropriate starting strength for the individual — not a compromise, but a considered choice based on their profile, history, and treatment goals.

Courierpharmacy.co.uk divider

Why the Trichosol vehicle matters

The Trichosol base is clinically relevant in its own right. It removes the excipients most likely to cause scalp irritation — making it possible for patients to apply their treatment comfortably and consistently, which is one of the most important factors in whether any hair loss treatment works over time.

Courierpharmacy.co.uk divider

Why single-ingredient treatment can be the right choice

Not every patient needs to start with a combination formula. For some, a single-ingredient approach at the lowest available concentration is the most clinically appropriate way to begin. It allows the prescriber to assess individual response before expanding the formula. It may also reflect TrichoTest findings that indicate dutasteride alone — at this specific concentration — is the best-matched approach for the individual's genetic profile and treatment history.

If response is good, the formula can be built upon over time. If additional ingredients are indicated from the outset, TrichoTest and clinical assessment will guide that decision. Compounding makes either path possible.

Courierpharmacy.co.uk divider

What is the Dutasteride 0.05% in Trichosol solution used for?

Pattern hair loss in men and women

This product treats pattern hair loss, also called androgenetic alopecia. In men, this often appears as a receding hairline or thinning at the crown. In women, it may present as diffuse thinning or a widening parting. The aim is to support hair retention and encourage healthier growth where clinically appropriate.

Courierpharmacy.co.uk divider

The problems of hair loss

The practical problem is visible thinning. The internal problem is the loss of confidence that builds quietly alongside it. The deeper issue is that people should not have to feel dismissed or left to navigate treatment alone for something that so clearly affects daily life.

Courierpharmacy.co.uk divider

Who this formula is for

Some patients come to this formula because they are new to compounded dutasteride and want to start with a single ingredient at the lowest available strength. Others arrive because their TrichoTest results suggest a lower anti-androgen concentration is the most clinically appropriate choice, or because a single-ingredient approach is the most appropriate starting point for their profile. Others come because previous standard topical products caused irritation that made consistent treatment impossible — and the Trichosol base removes that obstacle. In all cases, a compounded single-ingredient Trichosol solution offers a more considered, personalised path than anything available off the shelf.

Courierpharmacy.co.uk divider

How does the Dutasteride 0.05% in Trichosol solution work?

Pattern hair loss is driven by a hormonal process. Dutasteride addresses that process directly.

Courierpharmacy.co.uk divider

Dutasteride: blocking the hormonal signal

In pattern hair loss, follicles gradually shrink under the influence of DHT. Hairs become finer, shorter, and less visible over time. Left unaddressed, follicles eventually stop producing visible hair altogether.

Dutasteride blocks two forms of 5-alpha reductase — types 1 and 2 — reducing the conversion of testosterone into DHT. Finasteride only blocks type 2. This makes dutasteride more comprehensive and potentially more effective for people who have not responded well to finasteride.

At 0.05%, the concentration is deliberately cautious. It is the lowest available compounded strength and reflects a clinical judgment that this is the right place to begin — or in some cases, the right ongoing concentration. Starting at the lowest available dose is not a lesser approach. It is a considered one.

Think of dutasteride as taking the foot off the brake — reducing the hormonal pressure that shrinks follicles in the background.

Courierpharmacy.co.uk divider

Dutasteride 0.05% in Trichosol — Treatment dosage

This formulation is a topical solution and should only be used exactly as prescribed. The usual direction is: Apply 1ml at night to the scalp using the dropper bottle and wash off in the morning. Courierpharmacy.co.uk divider

A dose you can place precisely

The dropper bottle gives you direct control over where the solution goes. You direct it to the areas of thinning, not across the entire scalp. No spray drift. No product landing where it is not needed. In a Trichosol base, the solution sits comfortably without the sting of alcohol or the heaviness of propylene glycol. Courierpharmacy.co.uk divider

The right concentration for you

Because this is a compounded medicine, the prescriber selects the dutasteride concentration based on your individual clinical profile. At 0.05%, this formula uses the lowest available compounded dutasteride strength. It may be the right starting point for patients new to dutasteride, the right cautious approach for those with a sensitive response profile, or the right ongoing concentration for those whose TrichoTest results suggest a lower anti-androgen requirement. Courierpharmacy.co.uk divider

Building a routine that works

Many people find it easiest to apply as part of their evening routine — after a shower, before bed. The Trichosol base makes the application experience far more comfortable than a standard alcohol or propylene glycol-based product. Applied consistently at the same time each night and washed off in the morning, treatment has the best possible conditions to work. Courierpharmacy.co.uk divider

What to do if you miss a dose

Resume at the next usual time. Do not apply extra to make up for it. Consistent daily use over months matters far more than compensating for a missed night. Courierpharmacy.co.uk divider

Dutasteride 0.05% in Trichosol — Warnings and precautions

Who should not use this product

This product is not suitable for everyone. Extra care is needed if you are pregnant, trying to become pregnant, breastfeeding, have a scalp condition affecting absorption, or have a history of allergy to any ingredient in the formulation. Courierpharmacy.co.uk divider

Dutasteride warnings

Dutasteride affects hormone pathways. Women who are pregnant or may become pregnant must not use this product — it can affect male foetal development. Men with a history of prostate cancer, BPH, or elevated PSA levels need careful assessment before starting. Dutasteride lowers PSA levels, which may mask early prostate cancer. Baseline PSA screening may be required. Men with a family history of prostate cancer should discuss this with the prescriber. Courierpharmacy.co.uk divider

Minoxidil warnings

This formula does not contain minoxidil. However, if you are using minoxidil separately alongside this solution, it is important to note that minoxidil is a vasodilator and may not be appropriate for people with uncontrolled blood pressure, a history of heart attack, stroke, or other cardiovascular events, or those taking multiple blood pressure medications. Discuss any concurrent treatments with the prescriber. Courierpharmacy.co.uk divider

Post-finasteride syndrome

Post-finasteride syndrome (PFS) is a rare but recognised concern linked to 5-alpha reductase inhibitors, including dutasteride. It refers to persistent sexual dysfunction, mood changes, or other symptoms that may continue after stopping the medication. Topical dutasteride at 0.05% carries lower systemic exposure than oral forms, but the prescriber will discuss this risk during consultation. Any previous adverse effects from finasteride or related compounds must be disclosed. Courierpharmacy.co.uk divider

Tretinoin warnings

This formula does not contain tretinoin. If tretinoin is being used alongside this solution as part of a broader treatment plan, discuss concurrent use with the prescriber. Courierpharmacy.co.uk divider

Compounded does not mean casual

The Trichosol base and lowest available dutasteride concentration do not reduce the need for proper prescribing review. The same thorough safety and suitability checks apply here as with any other prescription treatment. A full medical history — including cardiovascular status, prostate health, previous medication reactions, and mood or sexual function concerns — will be reviewed during consultation. If you have had TrichoTest, those results will also be considered to ensure the formula and concentration match your predicted response profile. Courierpharmacy.co.uk divider

Dutasteride 0.05% in Trichosol — Side effects

Common side effects

Common side effects may include scalp irritation, dryness, redness, itching, flaking, or temporary shedding early in treatment. The Trichosol base reduces the likelihood of alcohol and propylene glycol-related dryness and stinging, but it does not eliminate the possibility of local reactions entirely. Early shedding can be unsettling, but it occurs as follicles shift through the hair cycle in response to treatment and usually settles with time.

Courierpharmacy.co.uk divider

Dutasteride-related effects

Dutasteride at 0.05% topical strength may cause sexual dysfunction in some patients — including reduced libido, erectile dysfunction, or ejaculation disorders. These effects are uncommon with topical application but have been reported. Mood changes, depression, or anxiety have also been documented with 5-alpha reductase inhibitors, though causality remains debated.

Report mood changes, persistent sexual dysfunction, or any other concerning symptoms promptly.

Courierpharmacy.co.uk divider

When to seek advice

Seek advice if you develop marked irritation, swelling, chest symptoms, dizziness, palpitations, signs of allergy, severe mood changes, or persistent sexual dysfunction.

Courierpharmacy.co.uk divider

Dutasteride 0.05% in Trichosol — Drug interactions

Why interactions still matter with topical treatment

Even as a single-ingredient formula, dutasteride carries interaction considerations. Thorough review before starting remains important.

Courierpharmacy.co.uk divider

Dutasteride interactions

Dutasteride may interact with CYP3A4 inhibitors and inducers. Strong CYP3A4 inhibitors such as ketoconazole or ritonavir may increase dutasteride levels. Enzyme inducers may reduce them. Topical absorption is lower than oral dutasteride, but relevant medicines will be reviewed.

Courierpharmacy.co.uk divider

Other scalp products

Other scalp treatments, harsh exfoliants, or irritating cosmetic products may increase the risk of local reactions. Concurrent use of multiple topical hair loss agents is not usually recommended without prescriber guidance. All current products should be disclosed during consultation.

Courierpharmacy.co.uk divider

Previous finasteride reactions

If you have a history of post-finasteride syndrome or adverse effects from finasteride, disclose this before starting. Dutasteride is a related compound. The prescriber will factor this into the clinical assessment.

Dutasteride 0.05% in Trichosol — FAQs

How long does it take to see results?

Hair loss treatment needs patience. Most people need several months of regular use before they can judge whether a treatment is helping. The Trichosol base makes consistent nightly application more comfortable — and comfort supports the consistency that treatment outcomes depend on.

Is this suitable for both men and women?

It may suit some adults, but the prescriber will assess this carefully. Hormonal considerations and pregnancy risk are especially important. Women who are pregnant or may become pregnant must not use this product.

Why is this a single-ingredient formula?

Not every patient needs a multi-ingredient formula from the outset. For some, dutasteride alone at the lowest available concentration is the most clinically appropriate starting point — whether because of their treatment history, their TrichoTest profile, or a clinical decision to assess response to a single ingredient before expanding the formula. A single-ingredient formula is not a lesser option. It is a considered one.

Why is the dutasteride concentration 0.05%?

0.05% is the lowest available compounded dutasteride concentration. The prescriber selects it when clinical assessment indicates this is the most appropriate starting or ongoing strength — whether because the patient is new to dutasteride, has a lower anti-androgen requirement suggested by TrichoTest, or has a cautious treatment profile. It is not a lesser option. It is the right option for the right patient.

Why is this formula in Trichosol?

Trichosol removes propylene glycol and alcohol from the base entirely. For patients who have experienced irritation, stinging, or dryness with standard topical solutions, it can make daily treatment significantly more comfortable — and comfort is what drives the consistency that good outcomes depend on.

What is compounding and why does it matter?

Compounding is the preparation of a medicine to order for an individual patient by a licensed pharmacy. It allows the ingredients, concentrations, and base to be tailored specifically to the person being treated. The 0.05% dutasteride concentration in this formula does not exist in any standard licensed product — compounding is what makes it possible.

Can I add more ingredients to this formula later?

Yes. One of the advantages of compounded treatment is that the formula can evolve over time. If clinical assessment or TrichoTest results indicate that minoxidil, tretinoin, or other ingredients would be beneficial, the prescriber can adjust the formula accordingly. Discuss this during your consultation or at review.

What makes this different from standard hair loss treatment?

It delivers dutasteride at the lowest available compounded concentration in a propylene glycol free and alcohol free Trichosol base — a combination that does not exist in any standard licensed product. It targets the hormonal driver of hair loss directly, in a vehicle the scalp is far more likely to tolerate comfortably. It is a more considered approach than anything available off the shelf.

Can I use it if standard hair loss products have irritated my scalp?

Quite possibly. The absence of propylene glycol and alcohol removes two of the most common causes of scalp irritation in standard topical solutions. Suitability still needs to be assessed by a prescriber, but for patients with reactive scalps this formulation is often a more comfortable and sustainable option.

How can TrichoTest help with this treatment?

TrichoTest analyses 26 genetic markers linked to hair loss susceptibility and treatment response across nine key pathways. It helps the prescriber decide whether this single-ingredient Trichosol formula is right for you — and whether 0.05% is the appropriate dutasteride concentration — based on your unique genetics rather than a standard protocol. It can also identify whether additional ingredients are likely to be beneficial, and which nutritional gaps or metabolic factors may be affecting your hair health.

Does TrichoTest guarantee the right treatment?

No. It reduces guesswork and supports more informed prescribing, but it does not guarantee results. Genetic testing works best alongside clinical assessment and your personal treatment history.

Will I need a prescription?

Yes. This is a Prescription Only Medicine. A UK-qualified prescriber must review suitability before supply. The consultation can be completed online at courierstaging.mystagingwebsite.com.

Can I stop if I see improvement?

Do not stop or change treatment without advice. Hair loss often returns to its previous pattern if treatment stops, even when results have been encouraging.

What is the Gro hair loss range?

Gro is the compounded hair loss brand from Courier Pharmacy and Medical Mojo. It offers liquid, foam, and Trichosol formulations, all priced at £29.99 for up to three active ingredients — less than £1 per day.

How much does this cost?

£29.99 for a 30ml bottle, designed to last around one month. Less than £1 per day.

How long does a 30ml bottle last?

Around one month when applied as directed — 1ml applied to the scalp at night using the dropper bottle.

What is the difference between liquid, foam, and Trichosol?

Liquid is a traditional spray solution containing alcohol and propylene glycol. Foam is lighter, faster-drying, and easier to apply without dripping. Trichosol is a propylene glycol free and alcohol free option for patients with sensitive or reactive scalps. All are available across the Gro range.

Is Trichosol better than liquid or foam?

It depends on your scalp and your previous experience with topical treatments. Trichosol is often the most appropriate choice for patients who have reacted to standard bases or who want a more comfortable daily experience. The prescriber can help you decide.

Can I use other hair loss products at the same time?

Concurrent use of multiple topical hair loss agents is not usually recommended without prescriber guidance. Disclose all current treatments during consultation.

What if I have had problems with finasteride before?

Disclose this during consultation. Dutasteride is a related compound and the prescriber needs this information to assess suitability safely.
