Valerian Root Precautions

Can increase the effects of sedative or anti-anxiety medications such as opiates, benzodiazepines and barbituates – exercise caution and take under supervision of a professional. Avoid if you take haloperidol.

Can cause drowsiness and reduced reflexes – do not take if you need to drive or operate machinery. In 10% of the population, valerian causes the opposite effect: instead of sedation it causes agitation and restlessness.
