Influence on ability to drive motor transport and control mechanisms
During the period of drug treatment, care should be taken when performing potentially hazardous activities that require increased concentration of attention and speed of psychomotor reactions (driving, working with moving mechanisms, the work of the dispatcher, the operator).
Overdosage
Symptoms: a single dose of 20 g of rhizomes with valerian roots (approximately 103 tab.) Can cause a feeling of fatigue, stomach cramps, a feeling of tightness in the chest, dizziness, hand tremor, dilated pupils that can pass on their own within 24 hours
Treatment: gastric lavage is recommended; symptomatic therapy is carried out if necessary.
