- California poppy may have additive effects when combined with other herbal or prescription sedatives (Marciano, 2015), and could increase the risk of motor impairment or drowsiness when combined with alcohol (Natural Standard, 2016).
- Use caution with prescription drugs such as MAO inhibitors and benzodiazepines (Mars, 2001; Natural Standard, 2016).
- California poppy should best be avoided by those who are pregnant or trying to become pregnant, as the alkaloid cryptopine found in California poppy has been shown in animal studies to have a stimulating, oxytocic effect on the uterus (Smith, 2010; Skenderi, 2003).
