Question 1

can i take a half dose of dayquil then 2 hours later take half a dose of nyquil? like when its 8 pm and want to stay up till 10 pm for example. since a full dose is supposed to be every four hours?

Accepted Answer

: Probably not ideal. There isn’t anything in DayQuil that should keep you awake, but there are ingredients in NyQuil that may make you drowsy. Please check this website for info:

https://sleepauthorities.com/does-dayquil-keep-you-awake/

The half dose of DayQuil may or may not be enough to quell your symptoms, and will not be fully metabolized when you take that later dose of NyQuil.

Question 2

is it ok to take 100 mg of trazadone with a dose of nyquil?

Accepted Answer

No: Please don't mix any nyquil preparation with trazodone. Nyquil has different combo preparations , all of which have ingredients that would interact with trazodone. Good that you asked, always exercise caution with multiple medications, good luck

Question 3

i have taken 1mg of xanex is it ok to take half a dose of nyquil severe for my cold?

Accepted Answer

Ok: at your age they may be additive, but not dangerous.
If you were elderly there would be more to consider.

Question 4

i took a ten mg hydrocodone at 9pm. it's now 1:30am, can i take half a dose of nyquil?

Accepted Answer

No: Avoid any kind of nyquil or the like if on hydrocodone, combination may cause several untoward symptoms of respiratory/CNS depression, consult your doctor about your  symptoms and which medicine would suit you better in your case, good luck

Question 5

i took 10 mg. zyrtec (cetirizine) about 7 hours ago and wonder if i can take a dose of nyquil before going to bed.

Accepted Answer

YES: however the use of both products should not exceed the doses you are using and you may have increased sedation.

Question 6

can i take my 10 mg zyrtec (cetirizine) along with a dose of nyquil to help sleeping with allergies?

Accepted Answer

Yes: But whether it will work or not is another question.

Question 7

i take 75mg effexor xr everyday at 11:30am i have a cough and chest congestion is it okay to take a dose of nyquil nighttime honey ?

Accepted Answer

: If that Nyquil product contains dextromethorphan, it is considered a threat to cause the dangerous serotonin syndrome when combined with Effexor. Just use honey for your cough to be safe or check with your prescribing MD or pharmacist to validate this advice.

Question 8

if i've had a dose of nyquil severe cold and flu already about 3 hrs prior, is it safe for me to take ibuprofen pm as well?

Accepted Answer

NyQuil has: Acetaminophen, doxylamine, dextromethonphan and phenylephrine. It’s fine to take additional ibuprofen but not PM. It’s not a good idea to mix diphenhydramine with doxylamine.

Question 9

i took 4 nyquil, even though the recommended dose is two. i did this because they expired 7 years ago. is this alright?

Accepted Answer

: No it is not. You should discard expired medication and only take the recommended dose. Expired medication loses its efficacy and doesn't work as intended.

Question 10

that would be 1300 mg, not 975mg--2@325 and one 650mg dose of nyquil. still ok? i accidentally took 2500mg and want to know f i'm ok.

Accepted Answer

The big problem : with Nyquil is the acetaminophen or Tylenol in it. It also contains the cough suppressant dextromethorphan and the decongestant pseudoephrine. While 2500 mg is getting up there, problems, especially liver damage, doesn't usually occur until a dose of &gt;4000 mg/day, especially repeatedly. So if it is just a one time thing, I think you should be fine. Stay well:)
