Key points

  • Ketoconazole is an imidazole antifungal that slows fungal growth by disrupting the cell membrane.
  • Oral ketoconazole carries serious liver and adrenal risks and is reserved for systemic infections where other antifungals are unsuitable.
  • The shampoo and tablet serve entirely different roles: one treats the scalp surface, the other enters the bloodstream.

Common questions about Ketoconazole

Why does ketoconazole come in both a shampoo and a tablet?

The shampoo delivers ketoconazole directly to the scalp to treat surface conditions like dandruff and seborrhoeic dermatitis, which can contribute to Hair Loss. The tablet enters the bloodstream to fight infections that topical treatment cannot reach. Because oral ketoconazole carries liver and adrenal risks, it is now used only when other antifungals are unsuitable.

What strengths does each Nizoral product come in?

Nizoral Shampoo is a 1% ketoconazole wash in a 200 ml bottle. Nizoral tablets come at 200 mg. These are the only two strengths listed: one applied to the scalp, the other swallowed.
