Special warnings and precautions for use
4.4
Seborrhoeic dermatitis is often associated with increased loss of hair which has also been reported -although in rare cases - in treatment with Ketoconazole shampoo.
In patients who have been on prolonged treatment with topical corticosteroids, it is recommended that the steroid therapy be gradually withdrawn over a period of 2 to 3 weeks, while using Ketoconazole shampoo 2%, to prevent any potential rebound effect. Avoid contact with the eyes. If the shampoo should get into the eyes, they should be bathed with water.
4.5 Interaction with other medicinal products and other forms of interaction
The systemic absorption of topically applied ketoconazole is minimal and systemic interaction with other medicinal products is unlikely.
4.6 Fertility, pregnancy and lactation
There are no adequate and well-controlled studies in pregnant or lactating women. Studies in animals have shown reproductive toxicity in high doses, indicating that ketoconazole may cause harmful effects with respect to foetal development. However, plasma concentrations of ketoconazole were not detectable after topical administration of Ketoconazole shampoo 2% to the scalp of non-pregnant humans. Plasma levels were detected after topical administration of Ketoconazole shampoo 2% on the whole body.
There are no known risks associated with the use of Ketoconazole shampoo in pregnancy or lactation.
4.7 Effects on ability to drive and use machines
Ketoconazole shampoo has no or negligible influence on the ability to drive and use machines.
4.8 Undesirable effects
The safety of Ketoconazole shampoo 2% was evaluated in 2980 subjects who participated in 22 clinical trials. Ketoconazole shampoo 2% was administered topically to the scalp and/or skin. Based on pooled safety data from these clinical trials, there were no ADRs reported with an incidence > 1%.
The following table displays adverse drug reactions (ADRs) that have been reported with the use of Ketoconazole shampoo 2% from either clinical trial or postmarketing experiences.
The displayed frequency categories use the following convention:
Very common (> 1/10); common (> 1/100 to < 1/10); uncommon (> 1/1,000 to < 1/100); rare (> 1/10,000 to < 1/1,000); very rare (<1/10,000); and not known (cannot be estimated form the available clinical trial data).

Reporting of suspected adverse reactions
Reporting suspected adverse reactions after authorisation of the medicinal product is important. It allows continued monitoring of the benefit/risk balance of the medicinal product. Healthcare professionals are asked to report any suspected adverse reactions via the Yellow Card Scheme (www.mhra.gov.uk/yellowcard).
4.9 Overdose
In the event of accidental ingestion, supportive and symptomatic measures should be carried out. To avoid aspiration, emesis or gastric lavage should not be performed.
5.1 Pharmacodynamic properties
Pharmacotherapeutic group: Imidazole derivates and triazole, ATC code: D 01 AC 08
The active substance of Ketoconazole shampoo is ketoconazole which is an imidazole compound.
Ketoconazole is an antimycotic with fungistatic effect on e.g. Trichophyton, Epidermophyton, Microsporum spp. and yeast fungi (Candida, Pityrosporum) when topically applied. Ketoconazole shampoo relieves itching and squamation, usually occuring in case of seborrhoeic dermatitis.
5.2 Pharmacokinetic properties
Percutaneous absorption of Ketoconazole shampoo is negligible since the concentration in the blood - even after long-term use - was below the detection limit of the analysis method (< 5 ng/ml). Therefore, no systemic effect is to be expected.
5.3 Preclinical safety data
There are no preclinial safety data considered relevant with regards to the assessment of the safety of topically applied ketoconazole.
