Ivermectin
Ivermectin is a prescription-only antiparasitic used to treat the inflamed spots and pustules of rosacea by killing Demodex mites and calming inflammation.
Ivermectin works by killing Demodex, the microscopic mites found in greater numbers on skin affected by rosacea, and by calming the inflammation around them. This settles the papules and pustules of papulopustular rosacea, and the redness that sits around them fades as they clear. In the UK, topical Ivermectin is available by prescription only. At City Skin Clinic, your doctor may prescribe Ivermectin alone or alongside other actives, in a cream or gel rosacea treatment, at a strength and protocol to suit your skin.
What Is Ivermectin and How Does It Work?
Ivermectin is a medicine that was initially developed to treat internal parasitic infections in human and veterinary medicine. It works by binding to the parasites’ nerve and muscle cells, which paralyses and eventually kills them. On the skin, it is also used to target Demodex. These are microscopic mites that live in the hair follicles and oil glands of most adult skin. They usually do not cause any problems but are thought to trigger inflammation in rosacea skin. Ivermectin also damps down the inflammatory signals the skin releases. As such, topical Ivermectin is thought to be beneficial in rosacea due to its antiparasitic and anti-inflammatory actions. This may help with:
- Papules and pustules: the raised, inflamed spots of rosacea, which clear as both the mites and the inflammation come down.
- The redness around active spots: as lesions settle, so does the inflammation surrounding them.
- Rosacea that keeps returning: it is used over a course rather than as a short burst, and your doctor reviews how your skin has responded before the next one.
Topical Ivermectin does not treat ocular rosacea, which is the eye involvement some people get alongside skin symptoms. Tell your doctor if your eyes are affected, because that needs looking after separately.

How City Skin Clinic Uses Ivermectin
We use Ivermectin in our rosacea treatments for suitable patients as part of a custom cream or a gel formula. Your doctor will select the strength and any additional actives to suit your skin and type of rosacea. They can also design the rosacea formula to address any additional skin concerns like hyperpigmentation, melasma, early signs of skin ageing or acne. Your doctor may pair Ivermectin with one or more of the following based on your needs:
- Metronidazole: the other prescription rosacea active we may use. It is an antibiotic which can also reduce inflammation.
- Azelaic acid: calms the inflammation behind rosacea and clears spots.
- Niacinamide: supports the skin barrier and reduces redness.
- Tretinoin: added where there are lines, texture or pigmentation to treat alongside rosacea.
When each course finishes, the same doctor reviews how your skin has responded and adjusts your next formula accordingly.
How Do You Get Ivermectin for Rosacea in the UK?
In the UK, topical Ivermectin is available by prescription only, so you will not find it over the counter. That leaves two routes, and which one suits you depends on whether a fixed formula with a single active is enough for your skin. The only licensed topical Ivermectin in the UK is Soolantra 10 mg/g cream, from Galderma. It is licensed for treating the inflammatory lesions of rosacea in adults. It comes in one strength (1%) and one cream base with Ivermectin as the only active in it. A compounded formula is the second route. These are unlicensed prescription treatments made individually for each patient by a specialist pharmacy. Your doctor can select the strength, combine it with other actives and formulate it in a cream or gel. This allows customisation of a treatment that can cover more than one concern.
For completion, Ivermectin is also licensed as 3 mg tablets for treating intestinal and other parasitic infections rather than for the skin. We treat skin with topical formulas only, so we do not use oral Ivermectin.
To access our custom skin treatments, you will need to complete the online consultation form or book a virtual video consultation with one of our doctors first. Your doctor will assess your skin, design a formula around what it needs and look after you afterwards. The same doctor stays with you, adjusts the treatment course by course and answers your questions by email.

Soolantra or Compounded Ivermectin
If you are considering Ivermectin, you have two routes in front of you. You can be prescribed the licensed cream Soolantra or have a formula compounded and made for you. Which one suits you depends on your skin, what else you are treating and whether a single active is enough.
| Soolantra | Compounded formula | |
|---|---|---|
| Strength | Fixed at 1% | Usually 1% but set by your doctor for you |
| What it is for | Inflammatory lesions of rosacea in adults | Rosacea, alongside the other concerns your skin has |
| Other actives | Ivermectin alone | Combined with other prescription actives where useful |
| Base | One cream | Cream or gel |
| Medical input | Prescriber decides suitability | Doctor designs and reviews each course |
| Adjusted over time | Same product each time | Adjusted course by course as your skin responds |
| Licensing | Licensed for rosacea in adults | Unlicensed, made for each patient by a specialist pharmacy |
| Shelf life once dispensed | Longer, as a batch-made product | Around three months, because it is freshly made |

How Effective Is Ivermectin?
Ivermectin is licensed in the UK to treat the inflammatory lesions of rosacea, and it is one of the better-evidenced topical treatments for them. This is what the evidence shows:
- Papules and pustules: this is where Ivermectin performs best. In a network meta-analysis of 32 trials and 11,399 adults, it reduced lesion counts further than Metronidazole and left more people with skin rated clear or almost clear. However, another analysis found Ivermectin, Azelaic acid and Metronidazole produced comparable effects. It may suggest that different people respond differently to these actives.
- Redness: the evidence does not really support its value alone for generalised flushing and redness. However, it can help reduce redness caused by inflamed pustules and papules.
- Rosacea maintenance: it is sometimes used as an ongoing treatment to help reduce flare-ups.
Most people see a first change at about four weeks, with the effect building over months, although this varies from person to person. Spots and pustules usually settle before the background redness, which is the slowest to shift.
What Strengths Does Ivermectin Come In?
The licensed cream contains 10 mg of Ivermectin per gram, which is 1%. The published rosacea trials used the same strength, so there is no higher-strength version with better evidence behind it.
We also mainly use 1% Ivermectin where appropriate in custom rosacea creams or gels. A compounded formula may also contain other actives, like Azelaic acid to further tackle rosacea symptoms or Tretinoin to combat photo-ageing.
What Are the Side Effects of Ivermectin?
Most people tolerate Ivermectin well. The most common side effects are local and usually settle as your skin adjusts. They include:
- Burning or stinging on application: most often during the first few weeks.
- Dryness, itching or irritation: where you apply it and usually mild.
Some people may find their rosacea briefly worsens during the first week or so before it settles. This is thought to be due to the skin reacting to the dying mites. There are also some more severe but less common side effects such as:
- An early flare that does not settle: if the worsening carries on past the first couple of weeks, or is severe, your doctor needs to know.
- Allergic reactions: rare, but stop and seek advice if you get swelling of the face or eyes, a rash beyond the application site or any difficulty breathing.
Regardless of severity, if you experience side effects when starting any treatment, always let your prescriber know straight away. If you’re a City Skin Clinic patient, just contact your dedicated doctor as all follow-up is free. For severe reactions like an allergy, it may be necessary to seek emergency medical assistance if you cannot immediately reach your provider.
Who Should Not Use Ivermectin?
Ivermectin suits most people with inflammatory rosacea. There are, however, a few situations that need extra care and some that rule it out:
- Allergy to Ivermectin or any ingredient in the formula: an outright reason not to use it.
- Pregnancy and breastfeeding: we do not prescribe Ivermectin during pregnancy or breastfeeding. The licensed product is not recommended in pregnancy, and whether it passes into breast milk after use on the skin has not been studied. Rosacea often changes during pregnancy, so your doctor will build a formula around actives that are suitable at that time.
- Under 18: the licensed cream has not been established as safe or effective in children, so we do not use it in that age group.
- Broken or inflamed skin: wait until it has settled, and keep it away from the eyes, lips and nostrils.
- Ocular rosacea: a cream on the face does not treat eye involvement. Tell your doctor if your eyes are affected so that can be looked after separately.
