    If i take dayquil at night will it keep me awake? ChaCha Answer: No. Dayquil does not contain any ingredients that will keep you awak

  2. Jay says:

    nope. the only things that keep you awake are stimulants. all cold medicines are a combination of drugs. meaning one drug treats fever, one treats the congestion, one treats the cough, and so on. the ingredients in Nyquil are: Acetaminophen (pain reliever/fever reducer) Dextromethorphan (cough suppressant) and Doxylamine (antihistamine.) DayQuil has the exact same ingredients except they leave the antihistamine out. the major side effect of antihistamines is their drowsiness. benadryl is the most popular antihistamine. since DayQuil doesnt have a stimulant in it, it wont keep you awake at night. the drug pseudoephedrine is a stimulant, and it is used in cold medicines, but it is not in either DayQuil or NyQuil. there is also a drug called Mucinex or guaifenesin that is an expectorant, it helps loosen the gunk in your chest that rattles around when you cough. but it isnt in DayQuil or NyQuil, to answer your question: DayQuil will not keep you up at night. it doesnt contain a stimulant that will keep you awake. it just doesnt have the antihistamine (doxylamine) that NyQuil has.
