Acne is one of the most common skin conditions in the UK affecting teenagers and adults alike. For adult women in particular, sensitivity to androgens is often a key acne driver. These “male hormones” can cause deep, painful spots along the jawline, chin and neck that flare with the menstrual cycle. Standard topical treatments and antibiotics don’t always work in these cases. This is why Spironolactone has gained popularity as a hormonal treatment for adult female acne. Thanks in part to the landmark SAFA trial published in the BMJ in 2023, there is now robust UK clinical evidence that Spironolactone can be effective for persistent acne in women. Despite this, Spironolactone is still not widely available for treating acne in the UK. In this post we review where it is possible to get oral and topical Spironolactone online and in person in the UK for acne treatment.
Why is Spironolactone for Acne Treatment Not Readily Available in the UK?
Spironolactone is strictly available by prescription only in the UK. This is because Spironolactone is a potassium-sparing diuretic that was originally developed to treat blood pressure and heart problems. It also has anti-androgen properties which means it blocks the effects of hormones like testosterone on the skin. This is what makes it useful for treating hormonal acne. By reducing the action of androgens on the sebaceous glands, Spironolactone decreases oil production. This in turn reduces clogged pores, inflammation and breakouts.
In the UK, oral Spironolactone is licensed by the MHRA to treat conditions like high blood pressure, heart failure, oedema and primary hyperaldosteronism. It is not licensed for acne treatment in neither oral or topical forms. However, doctors and certain health providers can prescribe it for this purpose as an unlicensed treatment for suitable patients. In fact, Spironolactone has been in use for treating hormonal acne in women for over 30 years. Following the publication of the SAFA trial, the NICE Clinical Knowledge Summary now also acknowledges Spironolactone as an option for women with persistent acne. The corresponding American and European acne guidelines also recommend this.
Is Spironolactone Safe?
The majority of adult women generally tolerate oral Spironolactone quite well. In the SAFA trial, over 95% of women were able to continue taking it for the full 24 weeks. For the majority, side effects were mostly minor. Common side effects include headaches, dizziness, breast tenderness, increased urination and menstrual cycle changes. However, more serious but rarer side effects can occur. This includes high potassium levels (hyperkalaemia), low blood pressure and kidney problems. For this reason most prescribers request blood tests to check your kidney function and potassium levels. These may be necessary both before starting and during treatment particularly at higher doses.
Oral Spironolactone is not safe for use in men as an acne treatment. This is because it can cause feminising side effects like breast tenderness and gynaecomastia. It is also not safe in pregnancy or in women trying to conceive, as it has potential anti-androgen effects on a developing foetus. There are also a number of important drug interactions to be aware of including certain heart and blood pressure medicines, NSAIDs and trimethoprim. All of these risks require careful discussion with a medical provider who is familiar with prescribing Spironolactone off-label before starting treatment.
What About Oral vs Topical Spironolactone for Acne?
Oral Spironolactone is currently in use off-label for treating women with hormonal acne in the UK mainly in tablet form. Typical doses for acne range from 50mg to 100mg daily with dose usually titrated up over several weeks. Most women see meaningful improvement in 3 to 6 months. Benefits usually continue as long with maintenance of treatment. However, whilst oral Spironolactone has the largest evidence base for acne, it also carries the greatest risk of systemic side effects. That’s why additional blood tests and monitoring are often necessary throughout treatment.
Topical Spironolactone is available by prescription in unlicensed compounded cream, gel or serum forms at concentrations between 1% and 5%. You usually apply it directly to acne-prone areas of the skin. Theoretically, delivering the drug directly to the skin may reduce systemic absorption and therefore the risk of systemic side effects like menstrual irregularities and changes in potassium levels. Studies suggest topical Spironolactone can be effective in acne with fewer side effects than oral treatment.
How to Get Spironolactone for Acne in Person in the UK
Since Spironolactone is not licensed for acne, it is generally not prescribed on the NHS specifically for this indication. That said, following the SAFA trial some NHS GPs and dermatologists are prescribing oral Spironolactone on a case-by-case basis for women with persistent acne. Most commonly, people need to see a private GP, dermatologist or other acne medical provider who is happy to prescribe oral Spironolactone off-label. They will need to counsel you thoroughly about the risks, check whether any blood tests are necessary and monitor you regularly. Depending on the clinic, they will either issue the prescription directly or send it to their partner pharmacy who will then post it to you. Topical Spironolactone is harder to get as it is only available through specialist clinics and dermatologists who prescribe compounded formulas. These are then formulated by a specialist compounding pharmacy then delivered to patients.
Where to Get Spironolactone for Acne Online in the UK
Spironolactone is significantly less widely available online in the UK than other acne treatments like topical retinoids or oral antibiotics. In fact, most of the well-known telehealth acne treatment services including Skin + Me and Dermatica do not currently offer Spironolactone at all. The large pharmacy online doctor acne services like Boots Online Doctor, Superdrug Online Doctor, LloydsPharmacy Online Doctor and Zava also do not generally prescribe Spironolactone for acne. Getting Spironolactone online therefore requires a medical provider that is specifically able to prescribe off-label or compound medicines. As with any prescription treatment, your provider should carry out a thorough medical review of your acne and overall health. They should also counsel you properly about the risks and only provide treatment if appropriate. Below are the main medical platforms where it is possible to get Spironolactone online for acne in the UK.
#1 City Skin Clinic
City Skin Clinic is an online medical clinic providing personalised prescription skin and hair loss treatments. We offer custom topical acne treatments following an online consultation by a UK registered doctor. Formulas can contain agents like Spironolactone, Tretinoin, Azelaic Acid, Clindamycin, Niacinamide and Hydroquinone where appropriate and safe. We provide topical Spironolactone acne treatments for adults if the doctor deems it safe and appropriate. Your doctor will advise the best strength and whether to include any other active ingredients in your formula. Treatments cost a flat fee regardless of strength or composition. A specialist compounding pharmacy formulates all treatments then delivers them directly to you. The same doctor will provide care throughout your treatment journey. They will monitor your progress and adjust the next formula as needed. You can either schedule a virtual video appointment or complete the online consultation form to access treatment.
#2 SkinDoc
SkinDoc is a UK online dermatology service led by consultant dermatologists. They have developed a dedicated Spironolactone service for women with persistent hormonal acne which combines a detailed questionnaire with photographs of your skin. They charge a flat fee for the consultation and written prescription but not the medication itself or any required blood tests. If approved, they partner with a pharmacy who dispense oral Spironolactone and deliver directly to you. Follow-up bookings are necessary for repeat prescriptions. This service mainly provides oral Spironolactone and Isotretinoin for acne.
#3 Medical Specialists
Medical Specialists is a UK online pharmacy with an in-house prescribing service. They offer oral Spironolactone (25mg, 50mg and 100mg tablets) for suitable women with hormonal acne, female pattern hair loss and hirsutism. After completing an online consultation, one of their prescribers reviews your suitability. They require that you have first spoken with your own GP or dermatologist about this off-label use and have had relevant blood tests. They will notify your GP with every prescription request. This model mainly serves to support continuity of your acne care by your GP rather than replace it. Once approved, the medication is dispatched by post.
#4 The Independent Pharmacy
The Independent Pharmacy is a GPhC and CQC regulated UK online pharmacy and doctor service which offers a range of prescription acne treatments. They do not offer Spironolactone but provide Winlevi cream which is another androgen blocking medication that is licensed for use in hormonal acne. You will need to complete an online consultation form and they will prescribe the treatment if appropriate following a clinical review. If approved, your prescription is dispensed by their pharmacy team and delivered to your door.
Spironolactone can be an effective treatment for adult women with persistent hormonal acne. Thanks to the SAFA trial, the UK evidence base is now stronger than ever and more clinicians are willing to consider prescribing it. However, it remains an unlicensed treatment for acne and hair loss in the UK and is only suitable for select group of patients. The number of online providers offering Spironolactone for acne in the UK is still relatively small and most big telehealth subscription services don’t offer it at all. Of those that do, most prescribe oral tablets only. Whichever service you choose, make sure it is a medical provider that offers a range of treatment options. They should undertake a thorough medical assessment, prescribe the best and safest treatment for you and counsel you honestly about the risks. Also ensure that they provide aftercare.
