Interactions with Drugs
Lagerstroemia indica has been shown to produce antithrombin activity. Caution is advised in patients with bleeding disorders or taking drugs that may increase the risk of bleeding. Dosing adjustments may be necessary.
Theoretically, banaba has been shown to produce insulin- like actions and therefore banaba may have additive effects when taken concomitantly with diabetic drugs. Medication adjustments may be necessary.
Caution is advised when taking concomitantly with xanthine oxidases.
Interactions with Herbs and Dietary Supplements
Lagerstroemia indica has been shown to produce antithrombin activity. Caution is advised in patients with bleeding disorders or taking herbs or supplements that may increase the risk of bleeding. Multiple cases of bleeding have been reported with the use of Ginkgo biloba, and fewer cases with garlic and saw palmetto. Numerous other agents may theoretically increase the risk of bleeding, although this has not been proven in most cases.
Banaba may lower blood sugar levels. Caution is advised when taking banaba with other herbs or supplements that may potentially alter blood sugar, such as fenugreek, garlic, or horse chestnut. Blood glucose levels may require monitoring, and doses may need adjustment.
