With anticoagulants (warfarin, heparin, aspirin, clopidogrel) → risk of bleeding increases.
With beta-blockers (propranolol, metoprolol) → counteracts Duvadilan Retard 40mg Capsule SR action.
With alcohol → risk of dizziness, fainting, and low BP.
With ergot alkaloids (used for migraine or postpartum bleeding) → may reduce effectiveness of both medicines.
