MODERATE — Monitor Closely
CAUTION — additive sedation
Evidence level: STRONG
Passionflower adds to Valium sedation.
Additive GABAergic sedation.
Use caution.
Caution with sedating botanicals. Valerian, kava, passionflower, and hops all enhance GABA activity — the same pathway Diazepam acts on. This can cause excessive sedation. If using calming herbs, take them at a different time and start with very low doses. Stimulating adaptogens are safer with benzodiazepines.
Elderly
Excessive drowsiness, impaired coordination
Disclose herbal use.
Combining sedatives increases overdose risk. Discuss with your doctor: magnesium glycinate, L-theanine, or passionflower may provide anxiety relief with fewer interaction risks. Never stop benzodiazepines abruptly — taper under medical supervision.
