Nizoral 2% Information

medically reviewed by Dr. HaVy Ngo, Pharmacist on February 6, 2026.

Nizoral 2% and Ketoconazole at CanadaPharmacyOnline.com

The manufacturer of Nizoral 2% (ketoconazole) varies by region, reflecting the global distribution of this specialized antifungal treatment. In Canada, the brand-name Nizoral 2% shampoo is primarily manufactured by Johnson & Johnson. In other international markets, such as the United Kingdom and Turkey, the brand is often associated with Janssen-Cilag.

While the brand-name version is a household name for scalp health, generic ketoconazole 2% is also available through various manufacturers that adhere to strict regulatory standards. The specific manufacturer of your dispensed medication may vary based on pharmacy inventory. While Nizoral 2% is a prescription-grade product in Canada, a 1% version is available over the counter for milder dandruff cases.

Important Information about Generic Ketoconazole

Generic ketoconazole contains the same active ingredient as brand-name Nizoral 2%. It must meet the same effectiveness and quality standards. This means it is designed to work in the same way as Nizoral 2%. Generic ketoconazole is pharmaceutically equivalent to Nizoral 2% and contains the same active ingredient and concentration. Because the medication works topically on the skin and scalp, it is not absorbed into the bloodstream in significant amounts.

Dosage:

Nizoral 2% (ketoconazole) is typically available in the following form and strengths:
• Shampoo: 2% (20 mg/mL), generally available in 60 mL and 120 mL bottles.
• Cream: 2% (20 mg/g), available in 30 g tubes

Generic ketoconazole is available as a 30 gm cream

For the treatment of dandruff or seborrheic dermatitis, the shampoo is usually applied twice weekly for 2 to 4 weeks, followed by once weekly or as needed for maintenance.

Usage:

Nizoral 2% is a potent antifungal shampoo primarily used to treat and prevent scalp conditions like dandruff and seborrheic dermatitis. An overgrowth of Malassezia often causes these conditions. This yeast-like fungus occurs naturally on the skin. Still, it can cause irritation, redness, and heavy flaking when it grows out of balance. Beyond the scalp, the 2% formulation is also used to treat tinea versicolor. This fungal infection causes discolored patches on the body. Unlike standard grocery store shampoos that wash away loose flakes, Nizoral is a medicated treatment that targets the underlying fungal cause. It is often recommended for more persistent or severe cases where lower-strength products have failed to provide relief.

Mechanism of Action
The active ingredient, ketoconazole, is an imidazole antifungal that disrupts the structural integrity of fungal cell membranes. It specifically inhibits the enzyme lanosterol 14-alpha-demethylase, which is essential for ergosterol synthesis. This vital component maintains the strength and fluidity of the fungal cell wall. By blocking ergosterol production, the medication makes the fungal cell membrane leaky and unstable, leading to the fungus's death. Furthermore, Nizoral has anti-inflammatory properties that help soothe the scalp's redness and itching almost immediately upon application. Because the active ingredient binds to the natural proteins in the hair and skin, it continues to work for several days even after the shampoo has been rinsed away.

Use Nizoral exactly as your doctor prescribes, following the instructions in the product monograph. For best results, massage the shampoo into a lather on the wet scalp and leave it in contact for 3 to 5 minutes before rinsing thoroughly. This ensures the medication has enough time to penetrate the scalp and target the fungus.

The information below summarizes some, but not all, potential side effects, risks, and interactions. Before starting Nizoral 2%, it is essential to discuss all possible side effects, risks, and interactions with your doctor or pharmacist.

Side Effects:

The information below outlines potential side effects of Nizoral 2% (ketoconazole). It is not an exhaustive list, and individual reactions can vary.

Common side effects: These are common side effects of Nizoral 2%; others are possible. Contact your doctor promptly if any side effects are persistent, worsening, or concerning, or if you experience any other concerning symptoms.
• Scalp irritation or redness
• Dryness of the hair or scalp
• Abnormal hair texture or oiliness
• Mild itching at the application site

Serious Side Effects: Seek immediate medical attention or call emergency services if you experience any of the following symptoms:
• Anaphylaxis: Severe allergic reaction involving swelling of the face, tongue, or throat, and difficulty breathing.
• Hair Loss: While rare, inform your doctor if you notice unusual hair thinning or loss during treatment.
• Severe Skin Reactions: Blistering, burning, or intense peeling of the scalp or skin.

Contraindications:

The following is not an exhaustive list of contraindications. Before starting Nizoral 2%, it is crucial to discuss all your medical conditions, past and present, and all medications you are taking with your doctor or pharmacist.

Do not take Nizoral 2%/ketoconazole if:
• Allergies: You have a known hypersensitivity to ketoconazole or any other "azole" antifungals (such as clotrimazole or miconazole).
• Broken Skin: Do not apply to a scalp that is severely broken, bleeding, or inflamed.

Tell your doctor about all of your medical conditions, past and present, before starting Nizoral 2%. This is crucial as certain conditions affect the drug's safety.
• Age: Nizoral 2% is generally not recommended for children under 12 unless directed by a specialist.
• Pregnancy: While systemic absorption is minimal, Nizoral should be used during pregnancy only if clearly needed.

Drug Interactions:

Before taking Nizoral 2%, discuss all potential risks and interactions with your doctor or pharmacist. For complete and up-to-date information, please visit the patient information leaflet at https://assets.hpra.ie/products/Human/22245/ca3de5d7-d613-4e89-8acc-2f68c789ff8b.pdf.

Provide your doctor with a complete list of all your medications, including prescriptions, over-the-counter (OTC) drugs, vitamins, herbal supplements, recreational drugs, and any significant dietary changes, as these may interact with Nizoral 2%. Topical Nizoral has very low systemic absorption, so interactions with oral medications are highly unlikely. However, you should still inform your doctor of:
• Topical Corticosteroids: If you have been using a steroid lotion or cream on your scalp long-term, your doctor may suggest tapering it off slowly while starting Nizoral to prevent a flare-up of your condition.

Pregnancy and Breastfeeding:

Nizoral is not typically detected in the blood after shampooing, making the risk to a fetus or nursing infant very low. However, use it only during pregnancy or while breastfeeding under a doctor's or pharmacist's guidance. Inform your doctor if you are pregnant, planning to become pregnant, or breastfeeding.

Use in Children:

The safety and efficacy of Nizoral 2% in children under 12 years old have not been fully established. Consult a pediatrician for appropriate pediatric scalp treatments.
