Medication questions Finasteride
Can women take finasteride?
Short answer
Finasteride is not licensed for women in the UK. The product information lists women as a contraindication because of the risk to a male baby in pregnancy, and a 12-month study in postmenopausal women found no benefit at 1 mg. Some NHS dermatologists prescribe it off-label in selected cases, but WMG Meds prescribes finasteride to men only.
Key facts
- Propecia (finasteride 1 mg) is contraindicated in women in the UK because of the risk in pregnancy.
- A 12-month placebo-controlled study in 137 postmenopausal women showed no benefit at 1 mg.
- Pregnant women should not handle crushed or broken finasteride tablets or topical finasteride.
- WMG Meds prescribes finasteride to men only.
What the UK licence says
The UK summary of product characteristics (SmPC) for Propecia, finasteride 1 mg, says it is "not indicated for use in women" and lists it as "contra-indicated for use in women due to the risk in pregnancy". The NHS is equally direct: "Women should not use finasteride."
The SmPC also reports a specific study: "Lack of efficacy was demonstrated in post-menopausal women with androgenetic alopecia who were treated with 'Propecia' in a 12 month, placebo-controlled study (n=137)." So at the licensed hair loss dose, finasteride was tested in women and did not help.
The pregnancy risk, and handling tablets
Finasteride lowers DHT, a hormone a male baby needs for his sex organs to develop normally. That is why the product information says crushed or broken tablets "should not be handled by women when they are or may potentially be pregnant". Whole tablets have a coating that prevents contact during normal handling.
This matters even if you are not the one taking it. If your partner uses finasteride, keep his tablets whole and in their packaging. If he uses a topical finasteride solution, a woman who is or may become pregnant should not handle it or apply it for him, because it can be absorbed through the skin.
Specialist off-label use
Some hospital dermatologists do prescribe finasteride to women, off-label, which means outside the terms of its licence. An NHS hospital patient leaflet from Gloucestershire Hospitals, for example, describes consultant prescribing for female pattern hair loss and some scarring hair loss conditions "after careful consideration of other treatment options", usually at 2.5 mg or 5 mg rather than 1 mg.
The same leaflet stresses that finasteride "is not suitable for women who are likely to become pregnant", must not be used in pregnancy or while breastfeeding, and lists mood changes among its side effects. In the UK, the MHRA's Drug Safety Updates of 29 April 2024 and 11 May 2026 warn that finasteride is associated with depression, suicidal thoughts and sexual side effects. Off-label use in women is a specialist decision, made case by case, not something to start from an online questionnaire.
If your hair loss could be a scarring type, such as frontal fibrosing alopecia, see your GP or a dermatologist. Our page on scarring alopecia explains why that needs specialist assessment.
What WMG Meds offers women
We prescribe finasteride and dutasteride to men only. For women with female pattern hair loss, the options a WMG Meds doctor can consider include topical minoxidil and, off-label, low-dose oral minoxidil, which is not suitable in pregnancy or while breastfeeding. Our page on whether women can use minoxidil covers both.
The British Association of Dermatologists' leaflet also lists non-drug options: wigs and hairpieces, camouflage sprays with coloured fibres, and private hair transplant surgery. Choosing no treatment is a valid choice too.
Hair thinning in women often has more than one cause, including iron deficiency, thyroid problems, PCOS and the menopause. WMG Healthcare offers a female hair loss blood test that looks for these. The free online assessment is the place to start if you want a doctor's view.

Can postmenopausal women take finasteride?
Not under the UK licence. A 12-month study of finasteride 1 mg in postmenopausal women found it did not work. Some specialist dermatologists prescribe higher doses off-label after assessing other options, but that is a hospital specialist decision.
Is it dangerous for a woman to touch finasteride tablets?
Whole, coated tablets are not a risk during normal handling. Women who are or may be pregnant should not touch crushed or broken tablets, and should not handle topical finasteride solutions, because the medicine could affect a male baby's development.
Can women take dutasteride for hair loss?
No. The UK Avodart product information lists women as a contraindication, and the leaflet says "This medicine is for men only." Women who are or may be pregnant must not handle leaking dutasteride capsules.
What can women use for hair loss instead?
Minoxidil is the usual medicine. The British Association of Dermatologists says applying minoxidil to the scalp daily "may help to slow down the progression and partially restore hair in some women". Low-dose oral minoxidil is used off-label. Wigs, camouflage products and hair transplant surgery are non-drug options.
Does WMG Meds prescribe finasteride to women?
No. We prescribe finasteride and dutasteride to men only. Women can complete the assessment for other options, such as topical or low-dose oral minoxidil, and a GMC-registered doctor will decide whether treatment is appropriate.
