Is ZzzQuil a Good Idea?

Thank you! This was the kind of response I was hoping for.

I haven’t tasted it; can anyone here tell us if it does, in fact, taste like NyQuil? (I use NyQuil when I’m really nasty sick; the flavor is unpleasant, but being that sick is so much more unpleasant!)

You are wrong for assuming that I have problems with sleeping, and you are dead wrong and really foolish for thinking that I think I have any kind of special insight. I started this thread to obtain opinions about a product. “In My Humble Opinion.”

Thank you; that’s actually helpful.

Okay! That makes sense. I never would have thought of it that way, and so this thread has served a useful purpose. Thank you for educating me.

This is one of my concerns with over-the-counter sleep aids in the first place. I’m not totally sure there should be such things at all. Again, people with serious problems might benefit from prescription meds, but ordinary sleeplessness doesn’t seem to me to rise to this level. I also worry about a vicious cycle of counteractants: people taking a sleep aid, then a waking aid, then a sleep aid, then a waking aid…

Ouch! Good luck to him (and to you.) I hope medical science advances (fast!) to provide a useful treatment.

Another insight I wouldn’t have arrived at without your help here. Thank you!

And this, too: thank you. This answers my real question.

To everyone else who posted, thank you. I know that “Just Asking Questions” is sometimes used as a fallacious manner of disguising an attack, and at least two posters seem to have mistaken my question for that fallacy. They, however, are the ones who have erroneously leaped to a (wrong!) conclusion. I opened this as an opinion question, and, with the exception of those two responders, I have gotten sensible, wise, intelligent, and knowledgeable answers. THANK YOU!

I know this thread is mostly finished but this is something I haven’t seen mentioned yet.

As someone who googled the hell out of diphenhydramine before buying any, I have to say the potential for prolonged abuse of it is nearly nihil. Tolerance builds up extremely fast for many folks (like, in a matter of days) and can take two or three weeks to go back down. And once you’ve built a lot of tolerance, no amount of upping your dose is going to get you the sleeping effect you were hoping for.

If I cut a 50mg capsule of diph in half, I can take the other half the next night and it will work. But after those two nights I’d need the full pill to get the same effect, and the night after that one I’m screwed.

It’s also a lot harder to hurt yourself with a diphenhydramine overdose than with, like, an Ambien overdose. Or with using alcohol to get to sleep (bad idea! Bad bad idea!), or as previously mentioned the mixed cold meds.

Of course, it was also mentioned that diphenhydramine may not even be the stuff in NyQuil. I don’t know; I use generic stuff.

It’s a different flavor, “berry”, but it’s that same cloying mediciny taste that people hate about NyQuil. Personally I like it. That plus the tinge of alcohol makes me feel like there’s substance to it that isn’t present in a pill or gelcap.

Maybe it’s just a placebo effect and I’m fooling myself into falling asleep. Far as I’m concerned, if it works, it works.

Fuck yeah.

Unisom (doxylamine succinate) is even better.

Try waking up at 3am, unable to get back to sleep, for a few days and see how your attitude shifts on this.

Hmm, you’re correct. Nyquil has doxylamine, not diphenhydramine. They’re both similar drugs though – first gen antihistamines with a major sedative side effect. Or sedatives with an antihistamine side effect, depending on the packaging.

If antihistamines are such great sleep-aids, then why does Nyquil need to add all that alcohol? I’ve always been under the impression that the alcohol was the real ‘knock-out’ punch delivered by Nyquil; in concert with the other ingredients. Take away the liquor and you just have some placebo syrup (IMHO).

My bad. I’ve never actually bought the name brand stuff, and I generally try to buy only single-medication stuff, so I don’t have to worry about ODing on mixtures or treating symptoms I don’t have. (Major exception: Theraflu, the kind in the little packets you mix with hot water. That stuff is awesomesauce, far beyond what each ingredient does on paper. Don’t try to talk me out of my placebo.) I knew NyQuil has some antihistamine, and assumed it was the most common and cheapest. I should have checked before posting. :smack:

This thread may have run its course, but for what it’s worth, both my cancer-patient uncle and my 90+ year old grandmother were advised by doctors to take Benadryl as a sleep aid. For my uncle, it was the recommended (for children) dose of the children’s liquid formula. I don’t know what the dosage was for my grandmother. It may not be good for everyone, but at least two doctors out there thought it was a good idea for a couple of folks with already-weakened systems.

Not that I’m any kind of expert, but I would figure it’s the combination of medication and alcohol that knocks you out more effectively than either one alone would.

If you’re drinking enough NyQuil for the alcohol to have a sedating effect, you’re definitely not following the label directions.

It is an INACTIVE ingredient. It’s there because at least one of the active ingredients is alcohol soluble, and the alcohol holds it in suspension. It is not there to promote sleepiness in any way whatsoever, or it would be in the ACTIVE ingredient section, by labeling law.

I can’t find anything on NyQuil’s site about how much alcohol is in there, but sources on the web claim 10% or 25%. The dose for an adult is 2 T. That’s the same as “a shot”, unless it’s less (some people use 1.5 oz for “a shot”). So we’re talking about a shot of wine or a shot of Captain Morgan’s. If you’re getting sleepy on a single shot of Captain Morgan’s, I’ve got a sorority house full of gullible girls to sell you…

I said “in concert” with the other ingredients; meaning that perhaps the alcohol, when combined with the other ingredients in the product, delivers a stronger punch than if consumed alone.

If it has any physiological effect, it’s not an inactive ingredient.

Inactive Ingredients in Approved Drug Products Search: Frequently Asked Questions | FDA

So, while, yes, alcohol can be an active ingredient sometimes, if it’s listed as an inactive ingredient, it cannot act as an active ingredient.

I see. So I went to find out why the alcohol was then included and this is what I found. Apparently it’s used as a solvent which blends the three active ingredients together. Ignorance fought.

Yay! We’ve both learned something in this thread! How very Doperish of us. :slight_smile:

Hell if it worked for me I’d take it instead of the demon drug Ambien. It’d be safer.

I was a bit worried by the word “intended” in the definition of “active ingredient.” If the ingredient isn’t intended to have a physiological effect…but does anyway…what then? The word seems to be out-of-place in a scientific sense, although it has very obvious utility in a legal sense.

Just so everyone is aware, sometimes diphenhydramine has a real rebound effect; that is, if you take it for several days in a row, it seriously wires you up. (I guess for some people it even has this effect the first time it’s taken.) Not much fun to take your sleepy-pill and suddenly find yourself jumping out of your skin. Why yes, I am speaking from personal experience.

See, there’s this problem.

In fact, when you buy Benedryl (or other sedating antihistimines) as allergy medicine, doesn’t it always say right on the package: “Caution, may make you sleepy. This effect will diminish after a few days, as your body gets used to the drug” (or words to that effect).

That right there is telling you precisely why diphenhydramine is not a good sleeping aid, other than for occasional and infrequent use. Your CNS quickly adjusts to it and the sleepy effect is more-or-less nullified. Then you will need bigger doses if you keep using it for more than a few days, and when you stop using it, you will have rebound insomnia for a while.

ETA: So, for you chronic insomniacs who have posted above: How does this play out for you? Do you use diphenhydramine regularly, and if so, does it remain effective? Or do you find that it loses its effectiveness when used regularly?

Right. It is generaly safe, but the generic cost about 1 cent per dose.

No, mine doesn’t mention anything about the effect diminishing. This is the first I’ve heard about it. I’m going to have to do some more research into this effect, because I’ve actually got a lot of patients whose doctors have prescribed diphenhydramine as a sleep aid to be taken nightly for long periods of time.

As I mentioned, the SO has found nothing that works past night 3 or 4. That includes diphenhydramine, Ambien, Ativan, trazadone, melatonin, passionflower/skullcap extract, warm milk, counting sheep…so I never considered that it might be a regular flaw of diphenhydramine.
