Clioquinol
Is It Right for You?
A complete guide to Clioquinol — what it treats, how it works, dosages, side effects, and when a clinician may prescribe it following an online consultation.
What Is Clioquinol?
Clioquinol is an antibacterial and antifungal agent used on the skin, usually combined with a corticosteroid such as betamethasone or hydrocortisone. It helps treat inflamed skin conditions where infection may also be present.
It is applied as a cream or ointment to the affected area. Clioquinol is most often found in combination products that pair its anti-infective action with a steroid's anti-inflammatory effect.
Clioquinol-containing preparations are prescription-only medications in the UK. A licensed clinician must review your skin condition and medical history before they can be prescribed - which can now be done conveniently through a telehealth consultation.
What Conditions Is Clioquinol Used For?
Clioquinol (usually with a steroid) is prescribed for:
treating inflamed skin where bacterial or fungal infection may be contributing.
managing inflammation and infection in skin folds.
where both inflammation and minor infection need addressing together.
Clioquinol can stain skin, hair, fabrics, and some materials yellow. Take care when applying it, protect clothing and bedding, and be aware that staining can be difficult to remove.
How Does Clioquinol Work?
Clioquinol has antibacterial and antifungal properties. It interferes with the growth and survival of a range of bacteria and fungi on the skin, helping to control minor skin infections.
When combined with a corticosteroid, the steroid calms inflammation - reducing redness, swelling, and itching - while clioquinol tackles any associated infection. The two actions complement each other.
This combination is useful for inflamed skin conditions that are infected or at risk of infection, where a steroid alone might otherwise allow the infection to worsen.
Dosages & Administration
The correct dose depends on the type and severity of infection, age, weight, and kidney function. Always follow your clinician's instructions. The table below is for general reference only.
Administration Tips
Apply a thin layer to the affected area only and wash your hands afterwards unless treating them.
Protect clothing and bedding, as clioquinol can stain. Allow the cream to absorb before dressing where possible.
Side Effects of Clioquinol
Side effects are usually local. As the product often contains a steroid, steroid-related effects can also occur with prolonged use.
- Yellow staining of skin, hair, or fabrics
- Mild burning or stinging on application
- Local irritation or itching
- Dryness
- Skin thinning with prolonged steroid use
- Worsening or spreading skin infection
- Severe allergic skin reaction
- Marked skin thinning or stretch marks (from the steroid component)
- Spreading rash or blistering
- Signs of steroid absorption with heavy, prolonged use
Keep clioquinol away from the eyes and use caution on broken or weeping skin, where absorption is greater. Stop and seek advice if irritation worsens.
Drug Interactions
Always disclose all prescription drugs, over-the-counter medicines, vitamins, and supplements to your clinician or pharmacist before starting clioquinol.
Other creams on the same area can alter the effect; leave time between applications as advised.
Airtight dressings increase absorption of any steroid component, so use them only if instructed.
Clioquinol can interfere with some thyroid tests. Tell the clinician arranging any blood tests that you are using it.
Important Warnings
Clioquinol stains skin, hair, nails, and fabric yellow. This is harmless but can be hard to remove. Apply carefully and protect clothing and bedding.
Because it is usually combined with a steroid, the same cautions apply - avoid prolonged use, large areas, and thin skin such as the face unless directed.
Use in children is limited and only on specialist or clinician advice, given their thinner skin and greater absorption. Avoid use under nappies unless instructed.
Use only if clearly needed, in small amounts and for short periods. Avoid applying to the breast before feeding. Tell your clinician if you are pregnant or breastfeeding.
Speak to a Clinician About Treatment
Getting advice no longer means sitting in a waiting room. Through The GP Service, you can consult with a licensed clinician in minutes — from home, on your lunch break, or wherever works for you. If treatment is clinically appropriate, your clinician can issue a prescription during the consultation. A consultation does not guarantee a prescription.
The treatment you need, when you need it.
Clioquinol FAQs
Yes. A licensed clinician can review your skin condition and history through a telehealth consultation and prescribe a clioquinol-containing preparation if it is clinically appropriate.
The steroid calms inflammation while clioquinol controls any associated bacterial or fungal infection, treating both problems at once in inflamed, infection-prone skin.
It can stain skin, hair, and fabrics yellow. The skin staining fades, but fabric staining may be permanent, so protect clothing and bedding when you apply it.
It is intended for short courses. Prolonged use is avoided, particularly because of the steroid component. Your clinician will advise on duration.
Only if specifically told to, and with care, as facial skin is thin and absorbs more. Keep it away from the eyes.
Apply it when you remember unless it is nearly time for the next one, then continue as normal. Do not apply extra to catch up.
