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.

If there are signs of an allergic reaction the product should be withdrawn.
