Short answer: Talk to your doctor before use if you take prescription medication — especially sedatives, benzodiazepines or antidepressants, blood-thinning drugs, or blood-sugar medication.
Why these specific medication classes are named together
Naming benzodiazepines, antidepressants and blood thinners directly gives you something concrete to check against your own prescriptions, rather than a vague "any medication" caution.
Why this caution connects to the formula's calming ingredients specifically
Given Corydalis, California Poppy and Passionflower are naturally calming, combining them with sedatives or benzodiazepines could compound this effect.
⚠️ Worth knowing: this is the same caution list worth discussing directly with a pharmacist if you take any of these medication types.
