Using sleeping pills or supplements for the first time can seem like a scary prospect—especially when you’re in an airplane cabin, closely surrounded by strangers who’ll witness your every sleep-induced move. But using the right ones can make you a more confident achiever of plane sleep: Over-the-counter or natural (read: non-prescription) options are unlikely to cause you a Bridesmaids moment of sleeping pill-induced panic that sends the flight into a tizzy.

Over-the-counter sleeping pills have only a few distinctive active ingredients—some of which you might prefer over others depending on your health needs and preferences. Here’s what to know about the best over-the-counter sleep aids out there, so you can ask your doctor about the kind you think you’d prefer.

Editor’s Note: This story includes both natural sleep aids and over-the-counter sleeping pills. All should be cleared for personal use by a doctor who’s familiar with your unique health conditions and medical history.

Types of Sleeping Pills

Diphenhydramine Sleeping Pills

If you’ve ever taken common sleep or allergy medicines like ZzzQuil, Benadryl, Aleve PM, or Tylenol PM, you’ve taken diphenhydramine. The active ingredient is an antihistamine that quells allergic reactions, with the added side effect of sleepiness that makes it common in sleeping pills.

Diphenhydramine is generally safe but shouldn’t be overused by those who need it for anti-allergy purposes. Overuse can lead to a higher tolerance to the active ingredient, which would mean needing to take more and more for it to continue working. A good rule of thumb is to only use diphenhydramine-based medicines when you really need them: when having an allergic reaction, or on a plane when it’s all you have and you really need some sleep. It’s probably best to use something a little more natural (more on that next).

Melatonin

Melatonin is the hormone your brain naturally releases when it’s tired, to trigger sleepiness, and is about as natural a sleep aid as you can get. It also happens to be available in pill form, so you can introduce the sleep-triggering chemical when it’s not naturally occurring, like on a cramped plane or for fighting jetlag. Like most sleeping pills, it can have some negative side effects if used long-term, but it’s generally the lightest sleep aid you can take, and will usually do the trick for sleeping pill newbies.

Doxylamine

If you’ve tried the natural stuff and found that you need something stronger to get to sleep on the plane, another antihistamine called doxylamine is a common active ingredient in stronger sleeping pills like Unisom sleep tablets and NyQuil cold medicine. The same antihistamine qualms apply, but if you’re not allergy-prone and not using antihistamines often, then sleep tabs like Unisom will offer a stronger effect. NyQuil has the added benefit of a pain reliever, fever reducer, and cough suppressant if you’re feeling sick and need some rest.

Valerian Root

Valerian root is a potent herbal supplement that causes surprisingly strong sedation and calms anxiety. Even the coated, pill version of this supplement usually has a strong smell that’s reminiscent of funky cheese—but it’s worth it. Called “nature’s Xanax” or “nature’s Valium” by some doctors, valerian root can instill sleepiness and relaxation within about 30 minutes, and it doesn’t have the same after-effect of drowsiness that I’ve experienced hours after taking other sleeping pills.

CBD

According to a study in 2019, CBD helped ease anxiety in patients but has yet to be fully proven to aid in sleep. However, if anxiety is part of the reason why you find it difficult to relax on an airplane, it may help you sleep. Also, many CBD sleep aids are mixed with melatonin to help you relax and sleep. 

CBD Hemp-derived CBD oils (with THC levels below 0.3 percent) are legal to fly with or be taken across state borders in the U.S., and with CBD becoming more and more popular and sales becoming legal, CBD is a great option for sleeping while traveling.

If you are a Tylenol user, then Tylenol PM is the better option for pain relief plus a sleep aid. Combining 500 mg Acetaminophen & 25 mg Diphenhydramine HCl, you’ll battle any aches and pains that come with travel while sleeping like a baby.

Kirkland Signature Sleep Aid

A favorite generic brand to many, Kirkland Signature Sleep Aid is a perfect budget choice to help you get that much-needed sleep on an overnight flight. Like other doxylamine medicines, take it about 30 minutes before you want to sleep for the best results.
