Can you become too accustomed to NyQuil that it does not work for you?

Answer 1

Yes your body can adapt to it just like any other over the counter or prescription medication. You should only take medication as instructed for a day or two unless directed otherwise by a doctor or pharmacist. The last thing you want is to be sick & taking something that will no longer work for you. That means your illness will / could get worst & could land you a ticket to your local hospital.

Answer 2

I haven't heard of becoming tolerant to NyQuil but I guess it's possible. Sometimes the reason those meds work differently is because we had something different to eat. Maybe too much caffeine. That usually renders them worthless for me, when I would normally feel drowsy and wanting to sleep. Maybe you could switch to something else if none of the above applies to you. Take a hot sleepytime tea or a couple of valarian. Benadryl helps some sleep as well as with their sinus troubles.

Answer 3

The new Nyquil does not have the active ingredient in it that it used to that stopped your nose from being runny and stuffed up. Its the same thing thats in Sudafed and that can only be bought behind the counter at your pharmacy.

Answer 4

No...it doesn't work that way..you can become used to the alcohol and take it for that reason...someday that too will be behind the pharmacy counter. Nyquil has a decongestant and antihistamine in it...and for those things, you don't build up a tolerance.

Answer 5

It is possible for the body to build a tolerance to any substance. Don't over do it; try something else.
