How to treat ringworm and tinea in Australia: which OTC antifungal cream to choose, how long to keep using it, hygiene to stop the spread, and when to see a GP.

Despite the name, ringworm has nothing to do with worms. It is a fungal skin infection — and the very same infection goes by different names depending on where it lands: ringworm on the body, athlete's foot between the toes, and jock itch in the groin. The good news is that most cases respond well to an over-the-counter (OTC) antifungal cream you can buy at any Australian pharmacy. The trick is choosing the right one, applying it correctly, and — crucially — not stopping the moment the itch settles. This guide unifies all three common types of tinea, decodes which pharmacy brand contains which active ingredient, and explains when a rash needs a GP rather than a tube of cream.
Ringworm — known medically as tinea — is an infection caused by dermatophytes, a group of fungi that feed on keratin, the protein in your skin, hair, and nails. These fungi thrive in warm, moist conditions, which is why tinea is so common in sweaty areas and in the Australian summer. It spreads through direct skin-to-skin contact, from animals (especially kittens and puppies), or from shared surfaces like gym mats, shower floors, towels, and footwear.
The classic sign of ringworm on the body is a red, scaly, itchy patch with a raised ring-shaped border and a clearer centre — which is where the misleading "worm" name comes from. It is one infection that shows up in three common places:
Other tinea types include tinea capitis (scalp), tinea unguium or onychomycosis (nails), and tinea manuum (hands). Scalp and nail tinea behave differently and usually need a doctor — more on that below.
Several antifungal active ingredients are available over the counter in Australia. They fall into two broad families: the allylamines (terbinafine) and the azoles (clotrimazole, miconazole, and others). The confusing part for shoppers is that the same active ingredient is sold under many different brand names. Here is the brand-to-ingredient decoder:
So which family should you reach for? Terbinafine's speed makes it a popular first choice for tinea corporis and athlete's foot. The azoles (clotrimazole, miconazole) are broader-spectrum, which is handy when a yeast might also be involved, but they generally need a longer, more disciplined course. There is no single "best" cream for everyone — your pharmacist can help weigh up where the infection is, how long you have had it, and your medical history.
| Active ingredient | Example brand | Typical use | How long to apply |
|---|---|---|---|
| Terbinafine | Lamisil AT | Ringworm of the body, athlete's foot, jock itch | Often around 1 week (follow the pack); faster-acting |
| Clotrimazole | Canesten | Ringworm, athlete's foot, jock itch, some yeast infections | Twice daily for 2–4 weeks |
| Miconazole | Daktarin | Ringworm, athlete's foot, jock itch, fungal skin infections | Twice daily for 2–4 weeks |
| Other azoles (e.g. bifonazole, ketoconazole) | Various pharmacy brands | Tinea of the skin | As directed on the pack (often 1–4 weeks) |
Getting results from an antifungal cream is as much about technique and persistence as it is about the product. Follow these steps:
Tinea spreads easily — to other parts of your own body and to other people. Pairing your cream with good hygiene helps it work and lowers the chance of reinfection:
This matters because eczema and tinea can look and feel similar — both can be red, scaly, and itchy. A few clues point towards tinea: a distinct ring-shaped border with central clearing, a rash on only one side of the body, or scaling and peeling between the toes. When in doubt, a pharmacist can help you tell the difference, and your GP can confirm the diagnosis with a simple skin scraping if needed.
OTC antifungal creams are designed for straightforward tinea on the skin. Some forms of fungal infection need prescription or oral antifungal therapy that a cream can't reach. See your GP if:
There is no instant fix, but an OTC antifungal cream applied consistently is the mainstay. Terbinafine (Lamisil) is often the quickest-acting option and may help ease the symptoms of ringworm of the body and athlete's foot within about a week of regular use. Speed also depends on technique and persistence — applying it correctly and finishing the full course gives the best result. A pharmacist can help you choose.
There is no single "best" cream for everyone. Terbinafine (Lamisil AT) is generally faster-acting, while clotrimazole (Canesten) and miconazole (Daktarin) are broader-spectrum and applied for longer. The right choice depends on where the infection is, how long you have had it, and your medical history, so it is worth a quick chat with your pharmacist.
It varies by location and product. Tinea on the body or feet treated with a cream often improves over one to four weeks, but you should keep applying for the full directed course past symptom relief. Nail and scalp infections take much longer — often months — and usually need a GP. If there is no improvement after two weeks of OTC treatment, see your doctor.
It is very unlikely. Ringworm is a fungal infection that generally persists and can spread without antifungal treatment. Symptoms might ease briefly, but the infection itself usually needs an antifungal cream to clear and tends to come back if left alone. Starting treatment early also lowers the chance of passing it to others.
Ringworm generally becomes much less contagious within roughly 24 to 48 hours of starting an effective antifungal, but it can remain transmissible until the infection has fully resolved. Keep up good hygiene — separate towels, no sharing of clothing or gear, and washing bedding — for the whole course, not just the first few days. If you are unsure, your pharmacist or GP can advise.
Not on its own. Hydrocortisone is a steroid, not an antifungal — using it alone on ringworm can mask the symptoms while the fungus continues to spread, a problem known as "tinea incognito". If you are unsure whether a rash is ringworm or an allergy, ask a pharmacist. For confirmed tinea, an antifungal is the appropriate OTC option.
