Quadriderm is a cream combining four active ingredients — a steroid, an antibiotic, an antifungal and an antiseptic. It is prescribed for inflamed skin that is also infected. Its breadth is both its use and its problem: it is very widely misused as a general-purpose skin cream, and doing that causes real harm.
What is Quadriderm?
The South African Medicine Price Registry lists Quadriderm as a Schedule 4 cream containing:
| Ingredient | What it is | What it does |
|---|---|---|
| Betamethasone valerate | Potent corticosteroid | Reduces inflammation, redness, itching |
| Gentamicin | Antibiotic | Kills bacteria |
| Tolnaftate | Antifungal | Treats fungal infection |
| Clioquinol | Antibacterial and antifungal | Broad antimicrobial |
Four ingredients means four sets of considerations, and this is not a simple cream.
Betamethasone valerate is a potent steroid — considerably stronger than hydrocortisone, which is the mild steroid sold over the counter. It suppresses inflammation quickly, which is why the cream feels so effective. It is also why it must be used for short courses on limited areas, and why using it on the face, in skin folds or on a baby is a problem.
The purpose of the combination is a genuine clinical situation: eczema or dermatitis that has become infected, where treating the inflammation alone would let the infection worsen, and treating the infection alone would leave the skin inflamed and itchy. In that situation, a combination is reasonable for a short course.
The problem is everything else it gets used for. Quadriderm is applied to undiagnosed rashes, to ringworm, to acne, to intertrigo, and to itchy patches of every description — often on a friend’s recommendation and reused from an old tube. This causes several specific harms:
Steroid on a fungal infection makes it worse. The steroid suppresses local immunity, the fungus spreads, and the rash loses its typical appearance — a phenomenon called tinea incognito, which makes diagnosis considerably harder afterwards.
Potent steroids thin the skin. With prolonged use the skin becomes fragile, shiny and easily torn, with visible small blood vessels and stretch marks. This is permanent. Skin folds, the face and the genital area are affected fastest.
On the face it causes steroid-induced rosacea and perioral dermatitis — a persistent red, bumpy rash that flares badly when the cream is stopped, which drives people to keep using it. Quadriderm should not be used on the face.
Skin lightening. Potent steroids reduce pigment where applied, which on darker skin produces visible patches that can take a long time to resolve. Steroid creams are also misused deliberately for skin lightening, which is genuinely damaging.
What is Quadriderm commonly used for?
Appropriate uses, on prescription:
- Infected eczema or dermatitis, where inflammation and bacterial infection coexist.
- Infected contact dermatitis.
- Intertrigo in skin folds, where inflammation, bacteria and yeast are all present.
- Infected insect bite reactions.
- Some inflamed fungal infections, briefly and alongside proper antifungal treatment.
Where a single-ingredient treatment is better:
- Plain eczema or dermatitis — a steroid alone, at the mildest strength that works.
- Ringworm, athlete’s foot, jock itch — an antifungal alone. Adding a steroid makes fungal infections worse.
- Impetigo or a bacterial skin infection — an antibiotic alone, sometimes by mouth.
- Acne — Quadriderm makes acne worse.
- Nappy rash — a barrier cream, and an antifungal if it is thrush. Potent steroids should not be used under a nappy, where the occlusion dramatically increases absorption.
- An undiagnosed rash — get it looked at.
Courses should be short, typically one to two weeks, on limited areas.
How Quadriderm fits into this medicine category
| Group | Examples | Notes |
|---|---|---|
| Combination creams | Quadriderm, and similar | Inflamed and infected skin; short courses |
| Topical steroids | Hydrocortisone (mild), Clomaderm, betamethasone (potent) | Inflammation alone |
| Antifungals | Canex V, clotrimazole, terbinafine | Fungal infection alone |
| Topical antibiotics | Mupirocin, fusidic acid | Bacterial infection alone |
| Emollients | Aqueous cream, ointments | The foundation of eczema care |
That last row deserves emphasis. In eczema, regular generous moisturising does more than any steroid to keep skin healthy and reduce flares. Steroids treat flares; emollients prevent them, and are used far less than they should be.

What to check before using Quadriderm
Do not use it on the face, unless a doctor has specifically directed it, and then only briefly.
Tell your doctor or pharmacist if:
- The rash is on the face, in skin folds, in the groin, or on a baby. Absorption is much higher in these areas.
- You are using it under a nappy or a dressing. Covering the skin dramatically increases absorption.
- You have or might have a fungal infection such as ringworm — the classic ring-shaped, scaly, spreading rash.
- You have rosacea, acne or perioral dermatitis, all of which it worsens.
- The area is weeping, crusted, spreading, or painful, or you have fever — that needs assessment, possibly with oral antibiotics.
- You have a viral skin infection — cold sores, shingles, warts, molluscum. Steroids let these spread.
- You have used it for more than two weeks, or repeatedly.
- You are pregnant or breastfeeding, or applying it to a child.
- You have a gentamicin or aminoglycoside allergy, or iodine sensitivity (relevant to clioquinol).
Practical points:
- Apply a thin layer to the affected area only, usually twice daily.
- Do not use it on large areas of the body.
- Use it for the short course prescribed, and stop.
- Do not reuse an old tube on a new rash. This is the commonest route to harm with this cream.
- Do not share it.
- Note that clioquinol stains skin, hair, nails and fabric yellow.
- Moisturise regularly if you have eczema, separately from the treatment.
Possible cautions and when to ask a pharmacist or doctor
Common effects: burning, stinging, itching or dryness on application, and yellow staining from the clioquinol.
With prolonged or extensive use: skin thinning, stretch marks, visible small blood vessels, easy bruising, lightening of pigment, increased hair growth at the site, and — where large areas are treated for long periods, especially in children — enough absorption to affect the body’s own steroid production.
Seek prompt medical advice for:
- The rash spreading, worsening, or changing appearance.
- Increasing pain, swelling, warmth, pus, or fever — suggesting the infection is not controlled.
- Skin becoming thin, shiny, fragile or bruising easily.
- A red, bumpy rash around the mouth, nose or eyes — perioral dermatitis, which the cream causes and which flares on stopping.
- A ring-shaped or spreading scaly rash, which suggests a fungal infection being made worse.
- A rash that returns worse each time you stop — this is steroid rebound and needs proper management.
- Any rash in an infant that is not settling.
Get emergency help for a widespread blistering or peeling rash, facial swelling with difficulty breathing, or a rapidly spreading red, hot, painful area with fever.
See a doctor rather than continuing to self-treat if:
- You do not know what the rash is.
- It has not improved within two weeks.
- It keeps coming back.
- You are using the cream regularly or long term — that is a signal the underlying diagnosis needs revisiting, not that you need more cream.

Frequently asked questions
What is Quadriderm cream used for? Skin that is both inflamed and infected — infected eczema or dermatitis, intertrigo in skin folds, and infected bite reactions. It contains a steroid, an antibiotic, an antifungal and an antiseptic.
Can I use it on any rash? No, and this is where most of the harm comes from. On a fungal infection the steroid makes it worse; on acne and rosacea it worsens them; on the face it causes a persistent rash.
Can I use it on my face? No, unless a doctor has specifically directed it. It causes steroid-induced rosacea and perioral dermatitis, which flare badly when you stop.
Can I use it for ringworm or athlete’s foot? No. Use an antifungal alone. Adding a potent steroid lets the fungus spread and makes it harder to diagnose afterwards.
How long can I use it? Short courses, typically one to two weeks on limited areas, as prescribed.
Is it safe for babies? Not without a doctor’s direction, and not under a nappy — occlusion dramatically increases absorption.
Why is it staining things yellow? The clioquinol. It stains skin, hair, nails and fabric.
Can I use my old tube on a new rash? No. This is the commonest route to harm with this cream. Get the new rash diagnosed.
