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 either its oral or topical form. 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’s the Difference Between Oral & 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 as treatment is maintained. 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 Do You Get a Spironolactone Prescription in the UK?
Spironolactone is a prescription-only medicine. Because it is not licensed for acne, you need a doctor willing to prescribe it off-label. In practice that means a private GP, a dermatologist or a regulated online clinic. Most NHS GPs and the big telehealth subscription services do not offer it for acne. The process involves a thorough consultation about your skin, medical history and any medications. Your prescriber may also arrange blood tests to check kidney function and potassium. If spironolactone is suitable, your prescriber arranges the medication (oral tablets or a compounded topical) and posts it to you. The sections below cover where to get it, in person and online.
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.
