About Nizoral
Nizoral is a brand-name oral tablet that contains the antifungal agent ketoconazole 200 mg. Approved in Singapore for the treatment of systemic fungal infections such as blastomycosis, histoplasmosis and coccidioidomycosis, it is also prescribed for selected skin-related mycoses when topical therapy is insufficient. By targeting the fungal cell membrane, Nizoral helps restore health in patients battling stubborn infections, while offering a convenient once-daily dosing option that fits modern lifestyles.
What is Nizoral?
Nizoral, marketed by Janssen Pharmaceutica (Johnson & Johnson), belongs to the azole class of antifungal agents. The Singapore Health Sciences Authority (HSA) approved the 200 mg tablet for systemic mycotic infections after rigorous clinical testing demonstrated efficacy and safety. Although originally developed for invasive candidiasis, its spectrum now encompasses dimorphic fungi and certain dermatophytes that require oral therapy. In the local market, Nizoral is a prescription medicine, and pharmacists may dispense it after verification of a valid prescription. When a generic version of ketoconazole is prescribed, it must meet the same bioequivalence standards as Nizoral, ensuring comparable therapeutic outcomes at a lower cost.
How Nizoral Works
Ketoconazole, the active ingredient in Nizoral, inhibits the fungal enzyme lanosterol 14α-demethylase, a key step in the synthesis of ergosterol-the sterol that stabilises fungal cell membranes. Without sufficient ergosterol, the membrane becomes porous, leading to leakage of essential intracellular components and, ultimately, fungal cell death.
After oral ingestion, Nizoral is absorbed from the gastrointestinal tract at an approximate rate of 70 %. Peak plasma concentrations appear within 2 - 5 hours, and the drug distributes widely, reaching skin, lungs, and the central nervous system. Hepatic metabolism via CYP3A4 produces inactive metabolites, and the average elimination half-life is about 8 hours, supporting once-daily dosing. Food modestly reduces absorption, but the effect is not clinically significant for most patients.
Why Nizoral is Used for Infections, Skin Conditions
- Invasive Dimorphic Fungal Infections - Diseases such as blastomycosis, histoplasmosis, and coccidioidomycosis involve deep tissue invasion. Ketoconazole’s ability to penetrate the bloodstream and reach intracellular sites aligns with the pathogens’ habitat, making Nizoral an effective systemic option.
- Chronic Candidiasis - When candida species affect internal organs or the bloodstream, oral ketoconazole offers a convenient alternative to intravenous agents, especially in stable patients.
- Refractory Dermatophytoses - Some skin infections persist despite topical therapy; oral ketoconazole reaches the dermal layers and nail beds where fungi hide, facilitating clearance.
- First-Line Position in Local Guidelines - Singapore’s clinical practice guidelines list azoles, including ketoconazole, as a viable first-line oral therapy for non-life-threatening systemic mycoses when susceptibility data support its use.
- Cost-Effectiveness Compared with Alternatives - While newer azoles such as voriconazole and posaconazole provide broader coverage, Nizoral remains a lower-cost choice when the infecting organism is known to be susceptible.
These advantages stem directly from the drug’s mechanism: by halting ergosterol production, Nizoral weakens the fungal cell wall, allowing the host immune system to finish the job.
Off-Label and Investigational Uses of Nizoral
Clinical investigations have explored oral ketoconazole for conditions beyond its approved indications, including prostate cancer, Cushing’s syndrome, and certain severe seborrheic dermatitis cases. Small-scale trials suggest that high-dose ketoconazole can suppress adrenal cortisol production, offering a pharmacologic route for Cushing’s management. However, these uses are not approved by the HSA in Singapore, and the potential for hepatotoxicity remains a concern.
Off-label use should only be considered under the supervision of a qualified healthcare provider.
Is Nizoral Right for You?
Nizoral suits adults who need systemic antifungal therapy and have no significant liver-related comorbidities. Ideal candidates include patients with confirmed dimorphic fungal infections, those who have failed topical regimens for skin-related mycoses, and individuals whose renal function remains within normal limits (ketoconazole is primarily hepatically cleared).
Pregnant or breastfeeding women should avoid oral ketoconazole because animal studies have shown adverse fetal outcomes, and the drug can pass into breast milk. Elderly patients may require closer liver-function monitoring, as age-related hepatic decline can heighten the risk of toxicity. Patients with known hepatic impairment, active hepatitis, or a history of drug-induced liver injury should be steered toward alternative antifungals.
Taking Nizoral Effectively
- Timing - Take the 200 mg tablet with a full glass of water in the morning. Consistent timing reinforces steady plasma levels.
- Food Interactions - A light meal can reduce gastrointestinal upset, but avoid high-fat meals that may slightly lower absorption.
- Alcohol - Limit alcohol intake, as both ketoconazole and ethanol exert stress on hepatic enzymes, potentially compounding liver toxicity.
- Missed Dose - If a dose is missed within 12 hours, take it as soon as remembered. Skip the dose if it is almost time for the next scheduled dose; doubling up is unnecessary and may raise adverse-event risk.
- Travel Considerations - Carry a copy of the prescription and a short medication summary when traveling abroad, as some countries restrict the import of oral azoles.
- Adherence - Completing the full prescribed course, even if symptoms improve early, prevents relapse and resistance development.
Understanding Side Effects and How to Manage Them
- Gastro-intestinal Disturbance - Nausea, abdominal discomfort, and mild diarrhoea arise from local irritation of the stomach lining. Taking the tablet with food or a probiotic supplement can alleviate these symptoms.
- Hepatotoxicity - Elevated liver enzymes are the most serious concern. Routine monitoring of ALT, AST, and bilirubin at baseline and every 2-4 weeks during therapy helps detect early injury. If transaminases rise three-fold above the upper limit of normal, clinicians typically discontinue Nizoral.
- Hormonal Effects - Ketoconazole blocks steroid synthesis, occasionally leading to gynecomastia or menstrual irregularities. Patients reporting breast tenderness or hormonal changes should alert their prescriber promptly.
- QT Prolongation - The drug can affect cardiac repolarisation, especially when combined with other QT-prolonging agents (e.g., certain antiarrhythmics). An electrocardiogram baseline is advisable for patients with known cardiac disease.
- Allergic Reactions - Pruritic rash or urticaria suggest hypersensitivity; immediate cessation and medical evaluation are warranted.
For mild side effects, supportive measures (hydration, antacids, symptom-specific OTC products) are usually sufficient. Persistent or severe reactions-particularly hepatic or cardiac-require urgent medical attention.

Frequently Asked Questions
-
What makes ketoconazole different from other azoles like fluconazole? Ketoconazole blocks a broader range of fungal enzymes, giving it activity against certain dimorphic fungi that fluconazole may miss. However, its higher risk of liver toxicity often leads clinicians to reserve it for infections where alternative azoles are less effective.
-
Can I take Nizoral with other azoles at the same time? Combining two azoles typically provides no added benefit and can increase the likelihood of adverse hepatic effects. If a drug-interaction concern arises, your prescriber will adjust the regimen accordingly.
-
Is it safe to use Nizoral while on statin therapy? Both ketoconazole and many statins are metabolised by CYP3A4, raising the chance of elevated statin levels and muscle toxicity. Your physician may lower the statin dose or select an alternative lipid-lowering agent.
-
How often should liver function be checked during therapy? Baseline tests are essential, followed by repeat monitoring every two to four weeks for the first three months, then monthly thereafter, especially if you have underlying liver disease.
-
Will Nizoral affect my hormonal balance? In rare cases, ketoconazole interferes with adrenal and gonadal steroid synthesis, potentially causing menstrual irregularities in women or gynecomastia in men. Discuss any hormonal symptoms with your doctor promptly.
-
Can I use Nizoral for fungal nail infections? Oral ketoconazole can reach the nail matrix, but guidelines often recommend newer azoles with better nail penetration. If your clinician deems Nizoral appropriate, treatment may extend to 12 weeks to ensure full nail growth.
-
What should I do if I experience severe stomach pain? Severe abdominal pain may signal hepatic or gastrointestinal complications. Stop the medication and seek urgent medical evaluation; early intervention prevents worsening injury.
-
Is there a risk of developing resistance to ketoconazole? Prolonged or sub-therapeutic exposure can select for resistant fungal strains. Completing the full prescribed course and adhering to dosing schedules minimizes this risk.
-
How does Nizoral compare cost-wise to a generic ketoconazole tablet? The generic version is typically 20 %-30 % cheaper, offering the same bioequivalence. Our platform lists both options so you can choose based on budget and brand preference.
-
Can I travel with my Nizoral supply? Yes, but keep the medication in its original packaging with a copy of the prescription. Some countries require a doctor’s letter; verify local import regulations beforehand.
