How does it work?

The active substance, ketoconazole, is believed to exert its antifungal effects by altering cell membranes, resulting in increased membrane permeability, secondary metabolic effects, and growth inhibition.

Although the exact mode of action of ketoconazole has not been fully determined, it has been suggested that the drug's fungistatic activity may result from a disruption in ergosterol synthesis.

How is it used?

Nizoral tablets are taken during meals. The daily dose for adults is 200 mg. If necessary, this dose can be doubled.

The duration of treatment depends on the type of disease.

  • With dermatomycosis and systemic mycoses, Nizoral is taken within 1-2 months.
  • Tinea ringworm requires therapy within 10 days.
  • For onychomycosis, treatment can last from 6 months to 1 year.
  • With candidiasis of the skin, the duration of treatment is 2-3 weeks.
  • Vaginal mycosis disappears after 5 days.

To prevent fungal infections, take 400 mg per day.

For children weighing 15 to 30 kg, the dose is usually 100 mg. To prevent fungal or yeast infections, children are prescribed 4 to 8 mg per kilogram of body weight once a day.

Frequently Asked Questions

What are Nizoral tablets used for?

Nizoral can be used for fungal infections of the skin such as ringworm, skin fungus caused by microsporia and infections caused by yeasts.

Can you buy Nizoral tablets over the counter?

Nizoral tablets require a prescription.

In what dosage forms can you buy Nizoral?

Nizoral is available in the form of tablets, cream and shampoo.

How do you know the active ingredient in Nizoral?

The active substance is called ketoconazole.

What is Nizoral?

Nizoral is an antifungal antibiotic used to treat severe fungal or yeast infections. Nizoral kills sensitive fungi by inhibiting the formation of the fungal cell membrane.

The active ingredient in Nizoral is called ketonazole. Nizoral is available in the form of oral tablets, skin cream and shampoo. The tablet is usually taken once a day for a week or more. The cream is applied once or twice a day for 2 to 4 weeks. The shampoo is used twice a week. Treatment with shampoo usually lasts 4 weeks.

When are Nizoral tablets used?

The oral tablets Nizoral are prescribed for the treatment and prevention of fungal diseases. The areas of application include:

  1. Treatment of stomach or intestinal mucosa affected by fungal infection;
  2. Treatment of chronic candidiasis when local therapy is ineffective;
  3. Treatment of systemic fungal infections (coccidioidomycosis, blastomycosis, chromoblastomycosis, histoplasmosis or paracoccidioidomycosis)
  4. Prevention of fungal diseases during chemotherapy.

Nizoral is also used to treat parasitic fungal infections on the skin that cannot be treated with topical medicines or the active ingredient griseofulvin, or in patients who cannot take griseofulvin.

Off-label, Nizoral tablets are used for drug treatment in life-threatening Cushing's syndrome with the aim of reducing cortisol production.

Taking Nizoral tablets for fungal meningitis is not as effective, since the drug poorly penetrates the blood-brain barrier.

Because there is a risk of serious hepatotoxicity, Nizoral tablets should only be taken if the benefit of treatment outweighs the potential risk.

What is to be considered?

Nizoral tablets are not safe for all patients. Before starting treatment, always tell your doctor the following:

  • if you suffer from allergies;
  • if you are pregnant or breastfeeding;
  • if you have other health problems;
  • if you are currently using another medicine;
  • if you use dietary supplements, vitamins or herbal products of any kind.

Nizoral tablets can cause serious side effects, including:

1. Liver problems (liver toxicity). There is a risk of serious liver problems that can lead to death or the need for a liver transplant. See your doctor if you have any of the following symptoms after taking it:

  • loss of appetite or weight loss (anorexia)
  • vomiting or nausea
  • fatigue
  • stomach pain
  • dark urine or light-colored stools
  • jaundice
  • fever or skin rash

2. QT interval prolongation. This prolongation can cause irregular heartbeats, which can be life-threatening. This is possible when Nizoral tablet form is taken at the same time as certain drugs such as quinidine, dofetilide, pimozide, cisapride, disopyramide, methadone, ranolazine and dronedarone. Talk to your doctor about other medicines you are taking before you start taking them. Tell your doctor right away if you feel faint, light-headed, or dizzy, or if your heart is beating irregularly or rapidly. This can talk about QT interval prolongation.

3. Serious heart problems. Contact your doctor if you experience heart palpitations, loss of breath, or dizziness.

Alcohol should be avoided during treatment with Nizoral tablets as alcohol consumption can increase the risk of serious liver problems.

If allergic reactions occur, you should consult a doctor immediately. Symptoms that may indicate an allergic reaction include skin rashes, hives, facial swelling, swollen hands and feet, difficulty breathing, and difficulty swallowing.

Do not combine Nizoral with other antifungal drugs.
