Fluvoxamine and Ginkgo Biloba, a caution.
Fluvoxamine impairs platelet aggregation by depleting platelet serotonin; Ginkgo's ginkgolides inhibit platelet-activating factor. Combined antiplatelet activity raises bleeding risk, especially with concurrent NSAIDs or anticoagulants.

Caution
What is happening. Fluvoxamine impairs platelet aggregation by depleting platelet serotonin; Ginkgo's ginkgolides inhibit platelet-activating factor. Combined antiplatelet activity raises bleeding risk, especially with concurrent NSAIDs or anticoagulants.
Mechanism. Fluvoxamine blocks platelet SERT, depleting 5-HT needed for normal aggregation. Ginkgolides A/B inhibit PAF receptors, providing an independent antiplatelet pathway.
Recommendation. Avoid Ginkgo biloba while taking fluvoxamine. Watch for bruising, nosebleeds, or GI bleeding and stop Ginkgo 7-14 days before any planned surgery.
