Systemic Antifungal Agents For Cutaneous Fungal Infections

2 Vaginal Yeast Infection Treatments for IMMEDIATE Symptom Relief | Home Remedies you MUST AVOID
  • David Ellis, Alan Watson

SummaryCutaneous fungal infections are usually treated topically, but nail and hair infections, widespread dermatophytosis and chronic non-responsive yeast infections are best treated with oral antifungal drugs. The oral drugs currently available in Australia for the treatment of cutaneous fungal infections include griseofulvin, ketoconazole, fluconazole, itraconazole and terbinafine.

IntroductionThe cutaneous mycoses are superficial fungal infections of the skin, hair or nails. Essentially no living tissue is invaded however, a variety of pathological changes occur in the host because of the presence of the fungus and/or its metabolic products. The principal aetiological organisms are:

  • dermatophytic moulds belonging to the genera Microsporum, Trichophyton and Epidermophyton which cause ringworm or tinea of the scalp, glabrous skin and nails
  • Malassezia furfur, a lipophilic yeast responsible for pityriasis versicolor, follicular pityriasis, seborrhoeic dermatitis and pityriasis capitis
  • Candida albicans and related species, causing candidiasis of skin, mucous membranes and nails

The usual approach to the management of cutaneous infections in immuno competent patients is to treat with topical agents. However, nail and hair infections, widespread dermatophytosis and chronic non-responsive yeast infections are best treated with oral antifungal drugs.

  • Leave the shampoo on for 3 to 5 minutes, then wash it off with water. Try not to get the shampoo into your eyes or mouth. If it gets into your eyes or mouth, rinse them with water.

    Do Home Remedies Work

    Perhaps youd prefer to try home remedies? According to the National Center for Complementary and Integrative Health , some research shows that applied to the skin, bitter orange oil may help with athletes foot, jock itch and ringworm infections. There is also some evidence that tea tree oil may be helpful for athletes foot or nail fungus, according to the NCCIH.

    There is limited evidence that apple cider vinegar can help treat vaginal yeast infections and thrush, a fungal infection in the mouth. When used on the skin, apple cider vinegar should be used with caution because it can lead to a chemical burn due to its acid content.

    Garlic has shown anti fungal properties against a yeast in the Candida family, as well as fungal infections of the scalp. And an early study showed that a cream containing a component of garlic relieved athletes foot in all 34 study participants. Some research has shown that garlic is active against toenail fungus. However applying garlic directly to the skin can result in burns and blistering, so do it with caution if you decide to try it.
