Warning issued for turmeric supplements
Herbal products containing turmeric could increase the risk of bleeding for people on some anticoagulants.
New Zealand’s Centre for Adverse Reaction Monitoring (Carm) has issued a warning about the products after it received a case report on a patient taking warfarin who began taking a supplement containing turmeric.
The patient had stable INR measurements, but within a few weeks of starting the supplement, their INR increased to over 10.
The report concluded that the turmeric-containing product had interacted with warfarin.
