Fungal infections: how to spot, treat and prevent them

Fungal infections are common and usually treatable, but they can be annoying and slow to heal. You’ll see them on skin (ringworm, athlete’s foot), nails (yellow, brittle nails), mouth (thrush), or in the genitals (vaginal yeast). The right steps—simple hygiene, the proper antifungal, and knowing when to get medical help—make a big difference.

How to recognize common fungal infections

A few quick signs: itchy, scaly patches on feet or groin point to tinea (ringworm/athlete’s foot). A white, cottage‑cheese look in the mouth that wipes off is usually thrush. Thickened, crumbly, yellow or brown nails often mean nail fungus. Vaginal yeast usually causes itching, white discharge, and soreness. If you have fever, spreading redness, or pus, that could be a bacterial infection or an infected fungal rash—see a doctor.

Practical treatment steps you can try

Start with the simplest, safest options. For skin fungus, use over‑the‑counter topical antifungals like clotrimazole or miconazole for 1–4 weeks as directed. Keep the area clean and dry; creams work better on a dry surface. Athlete’s foot improves faster if you use antifungal powder or spray and change socks daily.

For vaginal yeast, single‑dose fluconazole (prescription) or a 1–3 day topical azole (OTC) often clears symptoms. If it returns quickly or keeps coming back, talk to your clinician—recurrent yeast may need a longer plan. Oral antifungals like terbinafine are commonly used for nail fungus, but they take weeks to months and may require liver monitoring. Topical nail treatments exist but usually work slower and less reliably.

Mouth thrush responds to antifungal mouthwash or lozenges. If you use an inhaler, rinse your mouth after each use to reduce risk. If infections are widespread, very painful, or you have diabetes, HIV, or take immunosuppressants, get medical advice early. Don’t self‑treat with oral antifungals if you have liver disease or take interacting medicines without checking with a clinician.

How long before you see improvement? Skin infections often get better in 1–2 weeks; nails need months. If a topical treatment doesn’t help after two weeks, or symptoms worsen, see a clinician for a prescription and proper diagnosis—sometimes a skin scraping or nail sample is needed to confirm fungus.

Prevention is straightforward: keep skin dry, wear breathable fabrics, change socks and underwear daily, avoid walking barefoot in public pools or locker rooms, don’t share towels or nail tools, and dry between toes after showering. For recurring vaginal yeast, avoid unnecessary antibiotics, wear cotton underwear, and skip douching.

Griseofulvin for Pets: Treating Fungal Infections in Dogs and Cats

Griseofulvin is a go-to treatment for fungal infections in our furry friends, cats and dogs. It's particularly effective against infections caused by dermatophytes, which affect the skin, hair, and nails. Administered orally, it's absorbed through the pet's digestive tract and then binds to keratin cells, preventing the fungus from infecting new cells. However, it's important to note that Griseofulvin should be used with caution as it can cause side effects such as vomiting, diarrhoea or even blood disorders. Always consult your vet before starting any new treatment.
