Hello, my friend just took robittusin and dayquil without thinking about it. what should she do? she only feels drowzy right now, so should she sleep?

Sleep and hydration: Robitussin (guaifenesin) is expectorant and DayQuil is cough supressant - both used for cough - loosen up and suppers. Some sedation is normal and lines alone can make one tired. But keep hydrated, rest . Do not operate any vehicles or tools. If excessive sleepiness of not awaking on command - Emergency services may be appropriate. Depends on primary cause of cough.
