Systemic Antifungal Agents For Cutaneous Fungal Infections

  • 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.

When to use systemic therapy

Oral antifungal drugs

Dose Regime For Oral Fluconazole

For vulvovaginal candidiasis, a single oral dose of fluconazole 150 mg is usually effective. It can be repeated.

For dermatophyte infections and pityriasis versicolor, either 50 mg daily or 150 mg once weekly is taken for two to six weeks.

Once-weekly fluconazole is often used off-label to treat toenail fungal infections .

Larger doses are required for systemic infections.

Fluconazole is not normally used in children but doses of 5 mg/kg/day have been safely prescribed for a serious infection.

Diflucan: Effective Cure For Fungal Infections In A Form Of A Tablet

Diflucan is a clinically proven medication for fungal infections. The capsules are used to treat fungal infections in the body. Under normal conditions, many types of fungus live in our bodies at different locations, such as mucous membranes, inside the mouth and internal organs. Sometimes, however, they can cause different symptoms. Fungal infections range from harmless skin fungal infections to more serious diseases such as bronchi or brain diseases.

In this article, however, we focus especially on nail fungus. This condition is common on the toenails of middle aged males. The disease is rare in children. In additon, nail fungus on hand nails is less common. Most of the patients with toenail fungus have it also at the uppermost toe intervals and even on the soles of their feet. Nail fungus is usually caused by Trichophyton rubrum which is a dermatophytic fungus.

General Advice If You Are Diagnosed With Scalp Ringworm

If you are confirmed or your child is confirmed as having scalp ringworm then:

  • Where possible, you should throw out or disinfect objects that may be contaminated with fungal spores – for example, hats, combs, pillows, blankets and scissors. This aims to prevent re-infection after treatment and to prevent passing on the infection to others.
  • You should not share towels. Wash used towels frequently.
  • It is not necessary to keep children off school. However, to ensure that the infection is not transmitted to others, they should carefully follow the recommended treatment.
  • Monitor the scalps of other children in the household. If there are any signs of scaling or hair loss then seek medical advice.
  • If a pet is suspected of being the source of the fungal infection then seek advice from a vet for treatment.

Over The Counter Supplements Vs Prescription Medications For Candida

It may be tempting to think or believe that prescription medications are always more powerful than over the counter supplements.

And while this may make sense intuitively, it certainly isn’t always the case.

Some studies, such as this, have shown that herbal antibiotics/antifungals can be just as potent than conventional prescription medications.

Having said that, prescription medications certainly have their place, especially when treating gut-related issues such as SIFO and SIBO.

If you prefer the ‘all-natural’ approach OR if you’ve tried Diflucan/fluconazole without success, there are still many options available to you.

I’ve compiled a list of supplements below that you may want to consider if you have candida:

These supplements can also be combined with prescription medications to increase effectiveness and reduce the risk of fungal resistance.

When I treat patients for fungal overgrowth or candida, I typically use multiple options for that very reason.

Another important point to consider is that killing off candida is only part of the equation to treating your issue.

If you kill off candida but do not fix the issues that caused it to overpopulate in the first place then you will eventually end up where you started.

You will want to ensure that you take the proper precautions such as changing your diet , to reduce your stress , and provide your body with healthy probiotics to take the place of the candida once it’s gone.

Antifungal Creams And Shampoos

Antifungal creams or shampoos do not clear the infection fully. This is because fungi get into the hair shafts where creams and shampoos cannot reach. Therefore, they cannot cure the condition. They do, however, clear fungi and fungal spores from the hairs and surface of the scalp.

An antifungal shampoo or cream may be advised twice-weekly for a couple of weeks in addition to antifungal medication – for example, selenium shampoo, ketoconazole shampoo or terbinafine cream. This is to clear any surface fungi quickly and make it much less likely for the fungus to spread to other children.

How Is A Scalp Ringworm Diagnosed

Overview of Fungal Skin Infections | Tinea Infections

Sometimes the symptoms strongly suggest a fungal infection. However, scalp ringworm may be confused with other problems at first. For example, some cases can look like psoriasis or bad dandruff and fungal infection is just one of several causes of bald patches and hair loss. To confirm the diagnosis, a doctor will usually send a hair sample or a scraping of affected skin to the laboratory. This is looked at under the microscope and cultured to confirm that a fungal infection is the cause of the problem.

What If I Forget To Take A Dose

If you forget a dose, take it as soon as you remember, unless it’s nearly time for your next dose. In this case, just skip the missed dose and take your next one as normal.

Do not take a double dose to make up for a missed dose.

If you forget doses often, it may help to set an alarm to remind you. You could also ask your pharmacist for advice on other ways to remember your medicines.

Can Fluconazole Cause Problems

Along with their useful effects, most medicines can cause unwanted side-effects although not everyone experiences them. The table below contains some of the most common ones associated with fluconazole. You will find a full list in the manufacturer’s information leaflet supplied with your medicine. The unwanted effects often improve as your body adjusts to the new medicine, but speak with your doctor or pharmacist if any of the following continue or become troublesome.

Common fluconazole side-effects What can I do if I experience this?

Candida Infection Of The Skin

Candida infections of the skin respond well to a range of antifungals available in cream, powder, or solution formulations . Useful antifungals for candidosis are azole drugs . Other antifungal agents, not suitable for dermatophytosis, are the topical forms of the polyene antifungal drugs, such as nystatin, amphotericin B, and natamycin . Generally, superficial infections due to Candida of the skin and mucous membranes respond well to these treatments. However, most clinical trials have focused on oropharyngeal or vaginal infections, or cutaneous involvement in chronic mucocutaneous candidiasis .

Flexural candidosis. This refers to Candida infection in flexures such as the groins or inframammary fold, sometimes called Candida intertrigo. This requires topical therapy given for 2 weeks , but treatment may be continued for longer periods. Drying the infected site is also important in many cases where the moist skin surface can cause much discomfort.

What Causes Scalp Fungus

Like other fungal infections, scalp fungus develops when contagious fungi are transmitted onto your scalp and hair from other people, animals or objects.

Fungi can be found in almost every environment. When you come into contact with a fungus, it can spread onto your skin, causing an infection to develop. Often, it only takes a moment for a fungus to make its way onto your body and start growing.

Common sources of this type of fungal infection include:

  • People. Its possible to develop scalp fungus after contact with other people with fungal infections. The fungi that cause this type of infection can spread onto your hands from other people, then move to your head when you touch your scalp or hair.

  • Animals. Ringworm infections are common in animals, including dogs, cats and many farm animals. Many fungal infections are especially common in younger animals, such as puppies and kittens.

  • Items that are shared with other people, such as towels, clothing, combs, hairbrushes and other personal care products, can spread fungal infections.

  • The environment. Certain areas, such as damp surfaces in communal locker rooms or showers, are breeding grounds for the fungi that cause scalp ringworm and many other fungal infections.

Although scalp ringworm can affect anyone, its most common in children and people with weak immune systems. Like other fungal infections, scalp fungus tends to spread more often during the warmer periods of the year.
