This product is not recommended for use in children, adolescents under 18 years or for patients with a current pituitary disorder.

This product contains lactose:

1 film-coated tablet contains max. 124 mg lactose.

4.5 Interaction with other medicinal products and other forms of interaction

There are no published data available on drug interactions with extracts of Agnus castus.

Animal experiments have shown that that the drug has a dopaminergic effect and so, theoretically, there could be a reduction in the effectiveness of dopamine-receptor antagonists, and/or a potentiation of dopamine-receptor agonists.

4.6 Fertility, pregnancy and lactation

The safety of the product during pregnancy and lactation has not been established, therefore it should be avoided during pregnancy or while breastfeeding. Additionally, because of the potential for the product to have hormone-like actions the product should also be avoided by women who are trying to become pregnant.

Studies on the effects on fertility have not been performed.

  • Nausea

  • Headache
  • Diarrhoea
  • Allergic skin reactions.

If there are signs of an allergic reaction the product should be withdrawn.
