There are no adequate and well-controlled studies in pregnant or lactating women. Data on a limited number of exposed pregnancies indicate no adverse effects of topical ketoconazole on pregnancy or on the health of the foetus/newborn child. Animal studies have shown reproductive toxicity at doses that are not relevant to the topical administration of ketoconazole. No effects on the breastfed newborn/infant are anticipated. See Pharmacokinetic properties, section 5.2.
Plasma concentrations of ketoconazole were not detectable after topical administration of Nizoral Dandruff Shampoo to the scalp of non-pregnant humans. Plasma levels were detected after topical administration of Nizoral Dandruff Shampoo on the whole body. There are no known risks associated with the use of Nizoral Dandruff Shampoo in pregnancy or lactation.

Pharmacotherapeutic group: Imidazole and triazole derivatives, ATC code: D01AC08
Ketoconazole is a synthetic imidazole dioxolane antimycotic active against yeasts, including Malassezia, and dermatophytes. Its broad spectrum of activity is already well known.
Ketoconazole also has a direct anti-inflammatory action independent from its antifungal activity which may contribute to symptom relief in dandruff and seborrhoeic dermatitis.
Plasma concentrations of ketoconazole were not detectable after topical administration of Nizoral Shampoo on the scalp. Plasma levels were detected after topical administration of Nizoral Shampoo on the whole body.
Effects in non-clinical studies were observed only at exposures considered sufficiently in excess of the maximum human exposure indicating little relevance to clinical use.
