Generic Nizoral Information

Introduction

Nizoral is an antifungal medication that contains the active compound ketoconazole. It is used primarily to treat fungal infections of the skin and scalp, and it is listed under the anti‑fungal therapeutic group in the UK Medicines catalogue. The drug is marketed by Janssen‑Cilag (a subsidiary of Johnson & Johnson) and is available in several dosage forms, most commonly as a 2 % shampoo and as oral tablets. In addition to its main indication for dermatophyte and seborrhoeic dermatitis, ketone‑azole agents such as Nizoral have occasional off‑label use for certain systemic mycoses where oral absorption is required.

What is Nizoral?

Nizoral is a brand‑name product that delivers ketoconazole, a synthetic imidazole‑type antifungal. The medication was originally developed in the late 197s and received UK marketing authorisation in the early 199s. The shampoo formulation (2 % ketoconazole) is intended for topical application to the scalp, whereas the oral tablets (typically 200 mg) are taken systemically. Although Nizoral is a proprietary name, the same active ingredient is sold as a generic ketoconazole tablet or cream, providing a less expensive alternative for patients who have access to a licensed pharmacy.

How Nizoral Works

Ketoconazole belongs to the azole class of antifungal agents. It inhibits the fungal enzyme lanosterol 14α‑demethylase, a key step in the biosynthesis of ergosterol—a sterol essential for fungal cell‑membrane integrity. By blocking ergosterol production, ketoconazole destabilises the membrane, leading to increased permeability and ultimately fungal cell death.

Topical application to the scalp allows high local concentrations with minimal systemic absorption, delivering rapid reduction of Malassezia species that cause dandruff and seborrhoeic dermatitis. Oral tablets achieve systemic distribution, reaching skin, nails, and mucosal sites where dermatophytes may reside. The onset of symptom relief typically occurs within 1–2 weeks for scalp conditions and 2–4 weeks for systemic infections, reflecting the time needed for fungal eradication and regrowth of healthy tissue.

Conditions Treated with Nizoral

• Seborrhoeic dermatitis (scalp) – characterised by flaky, greasy scales; ketoconazole reduces Malassezia colonisation and inflammation.
• Tinea corporis, tinea cruris, tinea pedis – superficial dermatophyte infections of the body, groin and feet; oral ketoconazole penetrates skin layers to eradicate the fungi.
• Pityriasis versicolor – caused by Malassezia spp.; the shampoo formulation is an effective first‑line therapy.
• Systemic candidiasis (selected cases) – oral ketoconazole is occasionally used when alternative azoles are contraindicated, under specialist supervision.

In the UK, seborrhoeic dermatitis affects up to 5 % of adults, while superficial dermatophyte infections account for roughly 8 % of dermatology consultations annually, underscoring the clinical relevance of an accessible antifungal such as Nizoral.

Suitable Candidates for Nizoral Treatment

• Adults ≥ 18 years with confirmed or clinically suspected superficial fungal infections of the scalp, skin, or nails.
• Individuals who have not responded adequately to over‑the‑counter antifungal shampoos (e.g., zinc pyrithione, ciclopirox).
• Patients requiring systemic therapy because of extensive body‑surface involvement, recurrent infections, or infection of difficult‑to‑treat sites (e.g., toe‑nails).

Contra‑indications / cautionary scenarios

• Known hypersensitivity to ketoconazole or any formulation excipient.
• Severe hepatic impairment (Child‑Pugh class C) – oral ketoconazole is hepatotoxic in a minority of cases.
• Pregnancy (category B3 in the UK) and lactation – ketoconazole crosses the placenta and may be excreted in breast‑milk; risk‑benefit assessment required.
• Concomitant use of drugs that strongly inhibit CYP3A4 (e.g., clarithromycin, ritonavir) without dosage adjustment, due to risk of elevated ketoconazole plasma levels.

Risks, Side Effects, and Interactions

Common

• Gastro‑intestinal upset – nausea, abdominal pain, diarrhoea.
• Headache – reported in up to 5 % of oral‑tablet users.
• Skin irritation – erythema or itching at the site of shampoo application.

Rare

• Elevated liver enzymes – asymptomatic transaminase rise detected on routine blood tests.
• Hormonal disturbances – gynecomastia, menstrual irregularities, or decreased testosterone due to inhibition of steroid synthesis.

Serious

• Drug‑induced hepatitis – rare but potentially fatal; patients should discontinue the drug and seek immediate medical attention if jaundice, dark urine, or severe fatigue develop.
• Severe allergic reactions – anaphylaxis, angio‑edema, or Stevens‑Johnson syndrome; emergency care required.

Drug–Drug Interactions

• CYP3A4 inhibitors (e.g., azole antifungals, macrolide antibiotics, protease inhibitors) increase ketoconazole serum concentrations, raising toxicity risk.
• CYP3A4 inducers (e.g., carbamazepine, rifampicin, St John’s wort) reduce therapeutic effect, possibly leading to treatment failure.
• Warfarin – ketoconazole may augment anticoagulant effect; INR monitoring is advised.
• Oral contraceptives – reduced efficacy reported; additional non‑hormonal contraception should be considered.

Practical Use: Dosing, Missed Dose, Overdose

• Topical shampoo: Apply 2 % ketoconazole shampoo to wet scalp, massage for 5 minutes, leave for 3–5 minutes, then rinse. Use twice weekly for 4 weeks, then reduce to once weekly as maintenance.
• Oral tablets: Standard adult dose is 200 mg once daily for 6–12 weeks, depending on infection severity. In some cases, an initial loading dose of 400 mg on day 1 is recommended.

Missed dose – For oral tablets, take the forgotten dose as soon as it is remembered unless the next scheduled dose is within 12 hours; in that case, skip the missed dose and continue the regular schedule. Do not double‑dose.

Overdose – Symptoms may include nausea, vomiting, abdominal pain, and hepatic dysfunction. Seek urgent medical assistance; supportive care and activated charcoal may be administered in a hospital setting.

Precautions –

• Take tablets with food to enhance absorption and reduce gastric irritation.
• Avoid excessive alcohol consumption, which can potentiate hepatotoxicity.
• Patients with chronic liver disease should have baseline liver function tests and periodic monitoring while on therapy.

FAQ

• Is Nizoral available in both brand‑name and generic forms in the UK?
  Yes. Nizoral is the commercial name for ketoconazole, and generic ketoconazole tablets and creams are also licensed in the UK. The generic versions contain the same active compound and are usually less expensive.

• How should Nizoral shampoo be stored to maintain its effectiveness?
  Store the shampoo at room temperature, away from direct sunlight and moisture. Do not keep it in a bathroom cabinet where humidity is high, as prolonged exposure can degrade the active ingredient.

• Can I travel internationally with Nizoral tablets and still be compliant with UK regulations?
  Yes, provided you carry a copy of the prescription or a pharmacy‑issued label for personal use. Keep the medication in its original packaging and declare it at customs if required by the destination country.

• What are the inactive ingredients in the oral tablet formulation?
  Common excipients include lactose monohydrate, microcrystalline cellulose, magnesium stearate, and povidone. Patients with severe lactose intolerance should discuss alternatives with their prescriber.

• Do any foods interfere with the absorption of oral ketoconazole?
  High‑fat meals can increase ketoconazole absorption, while antacids containing aluminum or magnesium may reduce it. Taking tablets with a modest meal is recommended to balance absorption and gastrointestinal tolerance.

• Are there any specific warnings for patients of Asian descent taking Nizoral?
  Studies have shown a slightly higher incidence of liver‑enzyme elevation in some Asian populations. Routine liver function monitoring is advisable, especially during the first few weeks of therapy.

• How does ketoconazole compare with newer azoles such as itraconazole or fluconazole?
  Ketoconazole has a broader spectrum against dermatophytes and Malassezia species but carries a higher risk of hepatotoxicity and hormonal side effects. Newer azoles often have improved safety profiles but may be less effective for certain scalp conditions.

• What is the typical duration of treatment for nail fungus with oral ketoconazole?
  Treatment usually extends for 12 weeks or longer, depending on nail growth rate and severity of infection. Follow‑up cultures are recommended to assess eradication.

• Can Nizoral be used together with topical corticosteroids for severe scalp inflammation?
  Yes, a short course of a mild corticosteroid can accompany ketoconazole shampoo to reduce inflammation, provided the total steroid exposure remains within safe limits.

• Is there any risk of a positive drug test from using Nizoral?
  Ketoconazole is not a controlled substance and is not screened for in standard occupational drug‑testing panels. However, laboratories may detect it in specialized antifungal assays, which are rarely requested.

Glossary
