Dollars and cents of over-the-counter sleep aids

Americans sure have trouble sleeping. A Consumer Reports nationally-representative survey finds 20 percent have taken an over-the-counter sleep medication in the past year. Sales of ZzzQuil, the market leader, have reached more than 100-million dollars annually, according to the market research firm Mintel.

ZzzQuil’s commercials promise that elusive good night’s sleep.

So what is ZzzQuil?

“It’s just that same old antihistamine called diphenhydramine, also known by its brand name Benadryl. It’s been on the market over 70 years and one of its side effects is drowsiness,” says Lisa Gill, of Consumer Reports Best Buy Drugs.

It’s also in Sominex, Simply Sleep, and Unisom Sleep Gels. And it’s the ingredient that’s been added to these PM pain relievers to make you sleepy.

You can also buy generic diphenhydramine. It’s exactly the same active ingredient you find in ZzzQuil, but for one tenth the price per dose.

Products containing diphenhydramine do carry warnings, and Consumer Reports says be wary.

“You could experience daytime drowsiness or confusion, problems urinating, constipation, dry mouth and there’s some evidence that if taken frequently diphenhydramine is associated with an increased risk of Alzheimer’s,” says Gill.

Consumer Reports has these cautions when taking any sleep aid.

– Make sure you have a full night’s sleep after taking it.

– Don’t drive even after a full night’s sleep if you feel drowsy.

– Never mix it with alcohol or other sleep medication.

– And don’t take an extra dose if you wake up in the middle of the night.

ZzzQuil and other OTC sleep medications containing diphenhydramine are intended for short-term use, no longer than 14 days. If your sleepless nights last longer than two weeks, it’s time to talk to a doctor about another solution.  Click here to read more of Consumer Reports advice on how to get a good night’s sleep.
