Canex T is a clotrimazole 1% topical cream used to treat fungal skin infections — athlete’s foot, ringworm, jock itch and candida in skin folds. The “T” marks it as the topical cream; Canex V is the vaginal preparation. Keep applying it after the rash clears.
What is Canex T?
Canex T contains clotrimazole 1%, an azole antifungal, as a cream applied to the skin. It is a Schedule 1 medicine.
Check which Canex you have. The range includes Canex T for skin and Canex V, a vaginal cream with applicators for thrush. Both contain clotrimazole, but they are formulated differently and are not interchangeable.
Clotrimazole disrupts the fungal cell membrane. Fungi need a substance called ergosterol to keep their outer membrane intact; clotrimazole blocks its production. Human cells use cholesterol for the same job, which is why the cream damages the fungus without harming the skin it is applied to.
It is a plain antifungal — nothing else in it. That matters, because the alternative is a combination product such as Clomaderm, which adds a potent corticosteroid. The steroid settles itching and redness quickly, which feels better, but it also masks whatever is actually there.
For most fungal skin infections, a plain antifungal is the better choice. No steroid means no steroid-related concerns, and the infection clears just as effectively.
What is Canex T commonly used for?
- Athlete’s foot (tinea pedis) — itching, scaling and cracking, classically between the toes.
- Ringworm (tinea corporis) — a round, scaly patch with a raised, clearer-centred edge. Despite the name, there is no worm involved.
- Jock itch (tinea cruris) — in the groin and inner thighs.
- Fungal infection of the hands (tinea manuum).
- Candida infection in skin folds — under the breasts, in the groin, in abdominal folds, where warmth and moisture favour yeast.
- Nappy rash complicated by candida.
- Pityriasis versicolor, causing patches of lighter or darker skin on the trunk.
There are two situations where a cream will not do the job.
Nail infections need an oral antifungal such as the griseofulvin in Microcidal, or a specific nail lacquer, because cream cannot penetrate the nail plate.
Scalp ringworm requires oral treatment, since the fungus lives inside the hair follicles beneath the surface. This matters particularly in children, where untreated scalp ringworm can cause permanent hair loss.
In both cases weeks of cream produce no improvement — see a doctor rather than persisting.
How Canex T fits into this medicine category
| Group | Examples | Treats |
|---|---|---|
| Plain topical antifungals | Clotrimazole (Canex T, Fungistop Topical, Xeraspor T) | Fungal skin infection |
| Antifungal + steroid | Clomaderm | Inflamed fungal infection, short-term |
| Vaginal antifungals | Clotrimazole (Canex V) | Vaginal thrush |
| Oral antifungals | Griseofulvin (Microcidal), fluconazole, terbinafine | Nail and scalp infections, extensive disease |
| Topical corticosteroids | Hydrocortisone (Biocort) | Eczema and dermatitis — not fungal infection |
That last row is the important contrast: a steroid alone applied to a fungal rash makes it spread while appearing to improve. See the skin, wound and topical medicines hub.
What to check before using Canex T
Keep applying it for one to two weeks after the rash looks clear. This is the single most useful instruction here. The visible rash disappears well before the fungus is eradicated, and stopping when the skin looks normal is the main reason athlete’s foot and ringworm come straight back. Check the pack for the recommended total duration and finish it.
Apply a thin layer twice daily, extending a little beyond the visible edge of the rash, and wash your hands afterwards.
Speak to a pharmacist or doctor if:
- You are not sure the rash is fungal. Eczema, psoriasis, bacterial infection and other conditions can look similar, and an antifungal will not help those.
- The rash affects the scalp or nails — these need oral treatment.
- The rash is widespread, or on the face.
- The medicine is for a baby or young child.
- You are pregnant or breastfeeding.
- You have diabetes or a suppressed immune system, where fungal infections are more stubborn and foot problems need a lower threshold for review.
- The area is weeping, crusted, hot or spreading, which suggests bacterial infection needing different treatment.
- You have used it for the full course without improvement.
Possible cautions and when to ask a pharmacist or doctor
Reinfection is common, and it is usually about the environment rather than the cream. For athlete’s foot: dry between the toes thoroughly after washing, alternate shoes so each pair dries fully, wear cotton or moisture-wicking socks and change them daily, and wear something on your feet in communal showers and changing rooms. Treating the feet while putting the same damp shoes back on daily is the usual reason it recurs.
For jock itch, the fungus frequently travels from the feet — treat both at once, and put socks on before underwear so the towel and clothing do not carry it upward.
Wash towels and bedding hot, and do not share them while treating.
Mild burning or irritation on application is common early on. Increasing redness, blistering or worsening discomfort means stop and get advice.
If there is no improvement after two weeks, stop and get the rash looked at rather than continuing. A skin scraping can confirm whether it is fungal.
Seek medical attention for spreading redness, heat, swelling, pus or red streaking, which suggest bacterial infection; for fever alongside a skin infection; for any foot infection in someone with diabetes; for a rash that worsens on treatment; or for scalp or nail involvement.

Frequently asked questions
What is Canex T used for? Fungal skin infections — athlete’s foot, ringworm, jock itch, and candida in skin folds. It contains clotrimazole 1%.
What is the difference between Canex T and Canex V? T is the topical cream for skin; V is the vaginal cream with applicators for thrush. They are not interchangeable.
How long should I use it? Continue for one to two weeks after the rash looks clear. Stopping when the skin looks normal is the main cause of recurrence.
Can I use it on my nails or scalp? No. Cream cannot penetrate the nail plate or reach fungus in hair follicles. Those need oral treatment.
Is it better than a cream with steroid in it? For most fungal infections, yes. A plain antifungal clears the infection without steroid-related risks.
My athlete’s foot keeps coming back. Why? Usually the environment — damp shoes, insufficient drying between the toes, communal showers. Address those alongside the cream.
