Antihistamines should also not be used to help passengers sleep during a flight.

If you're nervous about the idea of prescription sleep aids, plenty of over-the-counter options await. A diphenhydramine tablet or two (i.e., Benadryl or Zzzquil) is enough to make most people drowsy, as is a single dose of cough medicine containing diphenhydramine and doxylamine succinate (a.k.a. Nyquil).
I recommend melatonin as a natural supplement to my patients with flight-related anxiety. Melatonin induces sleep and adjusts your circadian clock to help you function better when you reach your destination.
Does Benadryl Help Anxiety? Although some people say that Benadryl helps their anxiety, it is not approved by the FDA for anxiety symptoms. Therefore, do not take it for anxiety unless your healthcare provider specifically recommends it. The only FDA-approved antihistamine for anxiety is hydroxyzine (Atarax, Vistaril).
Yes, Benadryl is an antihistamine that causes drowsiness in most people. Some people use Benadryl for this side effect if they have trouble sleeping (insomnia), but this is not recommended long-term. The drowsy or sedation effect typically lasts about 8 hours, but may persist into the next day if taken at night.
If you react well to taking naps, then you should sleep for a few hours. Or if you find it easy to wake up in the middle of the night and function well, then you might want to sleep for a few hours. But if you find it easy to sleep on a plane, then you might want to stay up and sleep once you are in the air.
Don't Pull an All-NighterHowever, that sleep on the plane is never as good as the sleep you missed out on the night before. If you're somewhat rested and ready for a long journey, chances are you won't miss connections due to being rundown and listless from that all-nighter you pulled.
The best thing you can do to prevent jet lag is to get a lot of sleep the night before your flight. If you board the plane sleep deprived, you're less likely to fall asleep when you want to on the flight, and less likely to stay asleep. Not getting enough rest before a trip starts you at a disadvantage already.
Dramamine, a flight anxiety medication over the counter typically used to fight motion sickness, can perform double duty as an anxiety reliever for air travel. Medicine for flight anxiety over the counter, like Dramamine, is usually recommended for nervous flyers.
In the window seat, you can recline your seat just enough so you can still look out the window if needed. The seat usually has an adjustable headrest, so using this as a pillow adds a bit of comfort. Also, use the footrest or prop your feet on top of a carry-on bag.
Over-the-counter options include Dramamine (bonus: it will also help if you have motion sickness), melatonin (a hormone that can help with sleep and prevent jet lag), any antihistamine containing diphenhydramine (such as Benadryl), and medicines designed for insomnia, like Unisom or ZzzQuil.
