Can You Take Adrafinil and St. John's Wort Together?

Use extra care with this pair

The short answer

St. John's Wort increases serotonin availability, and Adrafinil affects monoamine neurotransmission including serotonin. This stacking may contribute to excessive serotonergic stimulation.

How to arrange timing

Exercise caution when combining St. John's Wort and Adrafinil. Start with low doses and watch for signs of serotonin excess.
