Medication questions Safety and side effects
Can you buy finasteride without a prescription?
Short answer
No. Finasteride is a prescription-only medicine in the UK. It must be prescribed after a proper consultation and supplied by a registered pharmacy, and the MHRA says it is a criminal offence to supply prescription-only medicines without a valid prescription. Websites selling it without one are acting illegally and may supply fake, contaminated or incorrectly dosed products.

Key facts
- Finasteride is a prescription-only medicine in the UK.
- The MHRA says supplying prescription-only medicines without a valid prescription is a criminal offence.
- Check the pharmacy on the GPhC register and the doctor on the GMC register.
- Report suspicious websites or products to the MHRA Yellow Card scheme.
Finasteride is prescription-only
The NHS says "Finasteride is available on prescription only", and that for hair loss "you can only get finasteride on a private prescription". It is a prescription-only medicine (POM), so a pharmacist cannot sell it to you over the counter.
The MHRA, the UK medicines regulator, puts it plainly: "It's a criminal offence to supply prescription only medicines without a valid prescription - websites offering them are acting illegally." The legal route is a consultation with a prescriber, who decides whether it is appropriate, followed by supply from a registered pharmacy.
Why a prescription matters for finasteride
Finasteride can cause side effects that need a conversation before you start. The MHRA issued Drug Safety Updates on 29 April 2024 and 11 May 2026. The 2026 update says finasteride "is associated with low mood, depression, suicidal thoughts and sexual dysfunction (decreased sex drive, erectile dysfunction and ejaculation disorders)", and that sexual dysfunction may persist after treatment is stopped. Patients taking finasteride 1 mg are told to stop immediately and contact their doctor if they develop depression or suicidal thoughts. Packs now include a patient alert card.
A prescriber should also check things like your age, other medicines and whether you have a partner who is or may become pregnant (women who are or may become pregnant must not handle crushed or broken tablets). See our MHRA safety updates page and finasteride and depression for more.
The risks of unregulated sellers
The MHRA warns that medicines from unregulated sources may be "fake, contaminated, incorrectly dosed, or contain powerful ingredients not listed on the packaging". Its #FakeMeds campaign adds that buying from dodgy websites can also expose you to card fraud and identity theft.
Its advice is simple: "Do not buy prescription-only medicines without a prescription", and "Only buy medicines from registered UK pharmacies or legitimate retailers." A site that offers finasteride with no consultation needed is a red flag.
How to check an online pharmacy or doctor
These checks apply to any service, including ours:
The pharmacy: in Great Britain, search the GPhC register to confirm the pharmacy that dispenses your medicine is registered. In Northern Ireland, the Pharmaceutical Society of Northern Ireland keeps the register.
The doctor: if the prescriber is UK-based, check they are on the GMC register. The CQC says doctors who are not GMC-registered "may not work to the same clinical standards".
The service: online doctor services based in England that employ GMC-registered doctors must be registered with the CQC. Services elsewhere in the UK may be regulated by Healthcare Improvement Scotland, Healthcare Inspectorate Wales or the RQIA in Northern Ireland.
What a legitimate consultation looks like
The GPhC says that to get a POM online you "would need to have an appropriate consultation with a prescriber", which may be an online questionnaire, chat, video or phone call, as long as it gives the prescriber enough information to decide safely. The CQC says the doctor should ask for a detailed medical history, current medicines and allergies, and "fully explain the risks and range of treatment options available so you can give informed consent".
At WMG Meds, part of CQC-registered Westminster Medical Group, a GMC-registered doctor reviews your health questionnaire, the MHRA advice is explained before any finasteride is prescribed, and medicines are dispensed by a GPhC-registered UK pharmacy partner. Our guide to what happens in an online consultation walks through it, or you can start the free online assessment.
Want an answer for your own situation?
A GMC-registered doctor can review your history and medicines and tell you what would suit you, including whether treatment is right for you at all. The assessment and review are free.

Is it legal to buy finasteride online?
Yes, if you have a valid prescription from a prescriber after an appropriate consultation, and the medicine is supplied by a registered pharmacy. Buying it without a prescription is not a legal route.
Can a pharmacist sell me finasteride over the counter?
No. It is prescription-only, so a pharmacy can only supply it against a valid prescription.
Is topical finasteride also prescription-only?
Finasteride-containing products for hair loss need a prescription. The combination topical WMG Meds can prescribe is an unlicensed special, prescribed only after assessment, and the MHRA finasteride warnings still apply in principle.
How do I report a fake or suspicious medicine?
The MHRA asks people to report suspicious websites or products through the Yellow Card scheme.
Do I have to have a video call for a legitimate consultation?
Not necessarily. The GPhC says consultations can take the form of online questionnaires, chats, video or phone, as long as the prescriber gets enough information to make a safe decision.
