Saw Palmetto × ADHD Medications Interaction

Mechanism

Saw Palmetto 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.
