I took Virtussin approximately 3 hrs ago and it has not helped my cough. I'm considering taking NyQuil but need to know when it would be safe to do?

At least 6 hours: Interval is needed to clear the codeine in Virtussin from your system, if not 8 hours. Nyquil contains an antihistaminic which would interact with the codeine. Moreover, codeine at times can cause spasm of the airways causing more cough, that's why it didn't help to start with, if you are really suffering call your doctor or go to urgent care for management, good luck ...Read more

Can NyQuil make you forgetful? Feel out of it? I've been taking NyQuil for a cough and lately I just feel so lost and out of it could this be why

Yes: Nyquil contains multiple ingredient in each capsule including one called Doxylamine which is an anti-histamine type medication (similar class as Benadryl). It is a first generation anti-histamine and therefore crosses the blood brain barrier and is known to cause sedation and "brain fog" after taking it and even after waking up in the morning. ...Read more

Can I take Zyrtec-D and NyQuil cough together?

ZyrtecD+Nyquil Cough: I would recommend that you NOT take these medications together at the same time because doing so will be like taking 5 drugs at the same time. Take the Nyquil Cough before going to bed. If needed, you can take the Zyrtec (cetirizine) D once daily as needed in the morning. Reserve the Nyquil for just before bedtime.
If you have diabetes or high blood pressure, check with your doctor first. ...Read more

My mom has been taking nyquil for 5 days but with no relief to her cough. What should we do for her dry cough.

My mom has been taking nyquil for 5 days but with no relief to her cough. What should we do for her dry cough.

A Dr should see her: Older people can get worn out from things like persistent coughing, so have a doctor evaluate her asap. It could be a condition that requires an antibiotic or another prescription. Instructions on the bottle advice that and it's true. Hopefully, she'll feel better sooner. Thanks for being there for her - most parents wish for that! ...Read more

I took the cough medication Hycodan (hydrocodone) at around 7pm. Its 10:30pm, would it be ok to take nyquil?

I took the cough medication Hycodan (hydrocodone) at around 7pm. Its 10:30pm, would it be ok to take nyquil?

Cough control: Hycodan (hydrocodone) can give excellent relief of cough. Unfortunately, if you are coughing again a lot after 3-4 hours, I would say the Hycodan (hydrocodone) levels are not sufficient to relieve the cough by itself. Hopefully, taking the NyQuil at that point will hopefully give you additive benefit. I would not typically take both meds together. If your cough is increasing/getting worse, see your doctor. ...Read more
