Dog Yeast Infection Treatment UK: Prescriptions, Prices & Where to Buy

Dog yeast infection treatment in the UK follows a set route: your vet confirms the yeast (Malassezia pachydermatis) with a quick cytology test, then prescribes a POM-V medicine — usually Malaseb, the 2% miconazole / 2% chlorhexidine shampoo, for skin, or a combination ear drop such as Surolan, Easotic or Osurnia for ears. Oral antifungals are kept for stubborn or widespread cases and are often prescribed under the VMD's "cascade". You do not have to buy the medicine at the practice: you can ask for a written prescription and fill it at an online vet pharmacy, and the Competition and Markets Authority is capping the fee for that prescription at £21 from 2027.

Between and after courses, over-the-counter chlorhexidine washes and a daily supplement do the maintenance work. For that daily layer, our pick for UK owners is Pure Majesty Pets yeast support drops at £25 — 19 named actives at about 292 mg per mL, with free delivery to the UK and duties and VAT prepaid, so there is nothing to pay the courier on the doorstep.

Quick answer: In the UK, the best-evidenced yeast shampoo (Malaseb, about £23.75 for 250 mL online when we checked) needs a vet prescription; chlorhexidine-only washes such as Douxo S3 PYO (from £16.75 for 200 mL) do not. Licensed yeast ear drops are POM-V too. Oral ketoconazole or itraconazole is a vet decision, usually under the cascade. Supplements are sold as complementary feed, need no prescription and support skin, gut and yeast balance — they do not replace the medicine.

How UK medicine rules shape your options

Before comparing products, it helps to know why some are behind the counter and others are in the pet shop aisle. The Veterinary Medicines Directorate (VMD) puts every authorised animal medicine into a legal category under the Veterinary Medicines Regulations 2013, and that category decides who can prescribe or sell it.

The practical upshot: anything that is actually licensed to treat Malassezia in dogs is POM-V, so the vet visit is not optional for a first episode. Supplements and cosmetic washes can be bought freely, but under UK feed law a supplement may not claim to treat or prevent disease — it can only support normal function. If a website promises a powder that makes yeast "go away for good", that is your cue to keep scrolling.

Step 1: the vet visit — what to expect

Expect a skin and ear examination and, for suspected yeast, cytology: tape or a swab pressed onto the greasy skin or ear discharge, stained and looked at under the microscope for the yeast's peanut-shaped cells. It is quick, it is one of the cheaper tests on a vet bill, and it separates yeast from bacteria, mites or plain allergy — each of which needs a different plan. For ears, your vet will also check the eardrum with an otoscope, because a ruptured drum rules out some drops.

Consultation fees vary a great deal across the UK. Following the Competition and Markets Authority (CMA) investigation into vet prices, practices are being required to publish prices for a standard list of common services and to say whether they belong to a large group — clear price lists are due from December 2026 at larger vet groups and March 2027 at smaller practices. If you are insured (Petplan, ManyPets and similar), check before the appointment whether a recurring skin or ear problem will be treated as a pre-existing condition at renewal. You can find practices near you through the RCVS Find a Vet directory.

Bring notes: when the smell or licking started, whether it flares in summer (grass pollen, roughly May to July) or late summer and autumn (harvest mites, most active July to November according to the PDSA), what shampoos or wipes you have already tried, and any recent antibiotics. Our guide to what you can give a dog with a yeast infection covers the questions worth asking.

What UK vets prescribe for dog yeast infections

Skin: Malaseb (2% miconazole / 2% chlorhexidine)

The World Association for Veterinary Dermatology consensus guidelines — whose lead author is Professor Ross Bond of the Royal Veterinary College — rate twice-weekly bathing with a 2% miconazole / 2% chlorhexidine shampoo as the topical treatment with the strongest evidence for Malassezia dermatitis in dogs. In the UK that product is Malaseb (Dechra), a POM-V medicine. The usual pattern is a bath twice a week with about ten minutes of lather contact before rinsing, for at least three weeks, then a recheck. Thick-coated breeds such as Springer Spaniels and Golden Retrievers need the lather worked down to skin level, and the coat dried fully afterwards. Our dog yeast infection shampoo guide explains technique and label reading.

Ears: combination POM-V ear drops

Yeast otitis is treated with prescription ear preparations that combine an antifungal with an anti-inflammatory and usually an antibiotic. Examples authorised in the UK include Surolan (Elanco; miconazole, polymyxin B and prednisolone), Easotic (Virbac; miconazole, gentamicin and hydrocortisone aceponate) and Osurnia (terbinafine, florfenicol and betamethasone, indicated for otitis externa associated with Staphylococcus pseudintermedius and Malassezia pachydermatis). Which one your vet chooses depends on what cytology shows and whether the eardrum is intact. Ear disease is one of the most common reasons British dogs see a vet: a Royal Veterinary College VetCompass study of 22,333 dogs under UK primary care found a one-year prevalence of otitis externa of 7.3%. Our guide to dog ear yeast infection treatment goes deeper.

Tablets and liquids: oral antifungals under the cascade

For widespread, severe or shampoo-resistant cases — or a dog who simply cannot be bathed twice a week — vets add an oral azole antifungal, most often ketoconazole or itraconazole. The WAVD guidelines rate their supporting evidence in dogs as moderate. Here is the UK detail most articles miss: the ketoconazole tablets authorised for dogs (Fungiconazol) are licensed for ringworm caused by Microsporum and Trichophyton species, not for Malassezia, and the authorised itraconazole oral solution (Itrafungol) is licensed for cats. So when a UK vet uses either for yeast dermatitis, they do so under the prescribing cascade.

Your vet will discuss liver monitoring on longer courses and check for interactions — azole antifungals can raise blood levels of some other drugs, including ciclosporin, which some allergic dogs also take. Dosing is individual, which is why you will not find dose figures here. More detail is in our guide to dog yeast infection medicine.

The cascade, explained for owners

The cascade is the part of the Veterinary Medicines Regulations that lets a vet prescribe outside a medicine's licence when, in the VMD's words, there is no available veterinary medicine authorised for the specific indication or condition in the animal being treated. In Great Britain the steps run in order: a UK veterinary medicine authorised for a different species or condition; then a UK-authorised human medicine or a veterinary medicine authorised outside the UK; then a medicine specially prepared (extemporaneous) by a vet, pharmacist or authorised manufacturer.

For yeast, this is routine rather than exotic. It does mean your vet carries the responsibility for the choice, may ask you to sign a consent form, and will set monitoring. It also means you should never source an antifungal yourself from an overseas website or use a human cream or tablet at home "because it's the same drug" — doses, carriers and safety in dogs differ, and the cascade decision belongs to the vet.

Written prescriptions and where to buy in the UK

For any POM-V medicine you have two choices: buy it from your practice, or ask for a written prescription and buy it elsewhere. You can ask for one today. The CMA's final decision on the vet market goes further: the fee for issuing a written prescription is capped at £21, with £12.50 for each additional prescription written at the same consultation — from March 2027 at larger vet groups (15 or more practices) and September 2027 at smaller ones — and practices will have to explain that you may be able to buy the medicine more cheaply online. Until the cap applies, each practice sets its own fee, so ask at the desk.

• Online vet pharmacies such as VetUK, Animed Direct, VioVet and Pet Drugs Online dispense POM-V products against a valid written prescription that you post or upload. Before ordering, check the seller on the VMD's Accredited Internet Retailer Scheme (AIRS) checker; accreditation is voluntary, but it is a useful sign the retailer follows the rules.
• Over the counter (no prescription): chlorhexidine washes and wipes, ear cleaners and supplements are sold by Pets at Home, Zooplus UK, Boots, Amazon UK, vet practices and online pharmacies. These support hygiene between medicated baths; none of them replaces Malaseb or prescription ear drops for an active infection.
• Direct from the maker: supplements such as ours ship straight to your door — with Pure Majesty Pets, delivery to the UK is free and duties and VAT are prepaid, so there is no customs charge to settle on arrival.

UK prices: what dog yeast products cost (checked October 2026)

Prices change and practices set their own, so treat these as a snapshot of live UK web pages we checked, not a quote. POM-V items need a valid prescription.

Two things stand out. First, the prescription medicines themselves are not wildly expensive online; the consultation and diagnostics are the larger part of most bills, which is why getting the diagnosis right first time matters. Second, most of what is sold for "itchy dogs" in the UK is a single-axis omega oil. That is useful for the coat, but it does nothing specific for the gut–skin axis or yeast balance — the gap our drops are built to fill.

Where a supplement fits — and why UK owners choose ours

Malassezia overgrowth is almost always secondary — to atopic dermatitis (house dust mites, grass and tree pollens), food allergy, hormonal disease such as hypothyroidism, or skin folds and ears that stay damp. The prescription clears the flare; the long game is managing that driver and keeping the skin and gut in good order so the next flare is smaller or does not come. That is where daily support earns its place.

The Pure Majesty Pets dog yeast infection treatment drops publish every amount per 1 mL: caprylic acid (MCT C8, 45 mg), MSM (45 mg), wild Pacific salmon oil (35 mg), L-glutamine (25 mg), a Saccharomyces boulardii postbiotic (20 mg), apple cider vinegar and NAC (18 mg each), berberine from Berberis aristata (15 mg), quercetin (15 mg), Pau d'Arco and calendula (8 mg each), oregano standardised to 70% carvacrol (4 mg, ~2.8 mg carvacrol) and zinc (2 mg), on a base of pumpkin, slippery elm, marshmallow root, DGL liquorice, aloe and ginger — roughly 292 mg of active support per mL. Several ingredients, notably caprylic acid and carvacrol-rich oregano, have laboratory antifungal data; evidence in live dogs is limited, and we say so, which is why we position the drops as support alongside your vet's plan rather than instead of it.

Why it is our top pick for UK owners at £25:

• Full disclosure — no proprietary blend, so you and your vet can see exactly what your dog is getting.
• Three systems in one bottle — yeast balance, skin comfort and the gut–skin axis, rather than an omega oil alone.
• Easy for fussy eaters — a liquid mixed into food, dosed by body weight per the label.
• No customs surprises — free delivery to the UK, with duties and VAT prepaid.
• Quality you can check — made in North America under GMP, with a certificate of analysis on every batch.

Useful companions: our Dog Ear Cleaner (£23, 120 mL, chlorhexidine-free, pH 5.0–5.5) for routine cleaning of yeast-prone ears once your vet confirms the eardrum is intact; our Liquid Probiotic for Dogs (£27, 60 mL) after antibiotics or when soft stools accompany skin flares; and our Allergy & Itchy Skin Chews (£39), with salmon and sardine oils, borage oil, quercetin and phytoceramides, for dogs whose yeast rides on seasonal allergy.

UK dogs that usually need a longer plan

Some dogs are simply more likely to need repeat prescriptions, so it is worth budgeting for maintenance from the start:

• Floppy-eared breeds. In the VetCompass otitis study, Basset Hounds had 5.87 times the odds of otitis externa compared with crossbreeds, followed by Chinese Shar Pei (3.44), Labradoodles (2.95), Beagles (2.54) and Golden Retrievers (2.23); dogs with pendulous ears had 1.76 times the odds of prick-eared dogs. Cocker Spaniels and Cockapoos with heavy, hairy ears fit the same pattern in practice.
• Classic yeast and allergy breeds — West Highland White Terriers, Shih Tzus, Basset Hounds and Cocker Spaniels are repeatedly reported at higher risk of Malassezia dermatitis.
• Fold breeds — French Bulldogs, Pugs and English Bulldogs, whose facial and tail folds hold moisture.
• Water-loving and muddy-walk dogs — Labradors and Spaniels that come home wet several days a week; drying routines matter as much as any bottle. Our at-home yeast care plan for wet British weather sets out a week-by-week routine.

When to go back to the vet

• Promptly: any ear pain, head tilt or loss of balance; skin that is raw, bleeding or spreading; or a dog who is off food or lethargic. Out of hours, ring your practice's emergency number or an out-of-hours vet service such as Vets Now.
• Within a week or so: no clear improvement after about three weeks of correctly done treatment, or a relapse soon after finishing a course.
• At your next routine visit: more than two flare-ups in a year — ask for an allergy or endocrine workup rather than another repeat of the same prescription. Our main dog yeast infection treatment guide grades every option by evidence and explains the underlying causes.

Frequently asked questions

Can I buy dog yeast infection treatment without a prescription in the UK?

You can buy chlorhexidine washes and wipes (such as Douxo S3 PYO), ear cleaners and supplements without a prescription. Medicines licensed to treat Malassezia — Malaseb shampoo, yeast ear drops and oral antifungals — are POM-V, so a vet must examine your dog and prescribe them.

How much does a written prescription cost in the UK?

Under the CMA's final decision on the vet market, the fee for a written prescription is capped at £21, with £12.50 for each additional prescription at the same consultation, from March 2027 at larger vet groups and September 2027 at smaller practices. Until then each practice sets its own fee, so ask before you book.

Is Malaseb a prescription-only medicine?

Yes. Malaseb (2% miconazole nitrate and 2% chlorhexidine digluconate) is POM-V in the UK. With a written prescription you can buy it from an online vet pharmacy; we saw it at £23.75 for 250 mL in October 2026.

Is ketoconazole licensed for dog yeast infections in the UK?

The ketoconazole tablets authorised for dogs in the UK are licensed for ringworm (dermatophytes), not Malassezia. Vets can still prescribe ketoconazole or itraconazole for yeast under the cascade, and will set the dose and any liver monitoring.

Where can I buy dog yeast products in the UK?

Prescription medicines come from your vet or, with a written prescription, from online vet pharmacies such as VetUK, Animed Direct, VioVet or Pet Drugs Online — check them on the VMD's AIRS list. Over-the-counter washes and supplements are sold by Pets at Home, Zooplus UK, Boots and Amazon UK, and our yeast drops ship direct with free UK delivery.

Can my vet prescribe a human antifungal for my dog?

Yes, under the cascade, if no suitable authorised veterinary medicine exists for the condition. It is the vet's clinical decision; do not give your dog human antifungal creams or tablets on your own.

Will I pay customs or VAT on Pure Majesty Pets orders to the UK?

No. Delivery to the UK is free, and duties and VAT are prepaid, so there is nothing to pay the courier or Royal Mail on delivery.
