next-day impairment
3 interactions related to next-day impairment
zolpidem + melatonin
Combining the Z-drug hypnotic zolpidem with melatonin can produce additive next-day drowsiness, impaired thinking, and reduced motor coordination, with the risk most pronounced in older adults. The interaction is primarily pharmacodynamic.
alprazolam + melatonin
Melatonin and alprazolam both promote sleep and can produce additive sedation, impaired alertness, and reduced motor coordination when used together. The combination may increase next-day drowsiness and risk during activities like driving.
zolpidem + valerian
Zolpidem is a Z-drug hypnotic that selectively binds the GABA-A receptor's alpha-1 subunit. Valerian's valerenic acid also modulates GABA-A receptors, producing additive sedation and a documented delay in next-morning psychomotor recovery when the two are combined.
