Ginkgo × ADHD Medications

MODERATE Cyp-Inferred Evidence

Mechanism

Ginkgo is a weak inhibitor of CYP2D6, which decreases metabolism of CYP2D6 substrates, potentially increasing their plasma concentrations and risk of adverse effects.

Effect

Increased plasma levels of atomoxetine (adhd-medications), potentially leading to toxicity or enhanced adverse effects.

Management

Monitor for increased adverse effects of atomoxetine. Dose reduction may be necessary. Consider alternative supplement or consult healthcare provider.

Plain Language Summary

✨ AI-generated · Qwen 3.6 · grounded in 2 sources · methodology

This combination carries a moderate risk because Ginkgo can slow down the way your body breaks down ADHD medications. This may cause the medication to build up in your system, which could increase the likelihood of experiencing side effects.
