Why You Shouldn’t Take Dramamine for Sleep

 Let’s dig into the science of Dramamine and other over-the-counter antihistamines. We’ll explore how they work, and why these medications are not the best choice for a good night’s sleep.

Why You Shouldn’t Take Dramamine for Sleep

Dramamine has been used as a sleep aid because diphenhydramine, a main component of Dramamine, causes drowsiness approximately 20 minutes after taking a dose of the anti-allergy medication. 

But interestingly, Dramamine also contains another compound that promotes alertness, so it is not a great choice for a sleep aid.  

When thinking about choosing a sleep aid, it’s best to start out with the question: “What will give me the best quality of sleep?” While the antihistamines Dramamine and Benadryl can help you fall asleep, they do not improve sleep quality.  

Beyond the fact that Dramamine is meant to treat motion sickness, not insomnia, Dramamine use can also have adverse side effects.

What is Dramamine?

Dimenhydrinate, which is commercially known as Dramamine, is an antihistamine medication used to treat motion sickness. Its intended use is to help prevent and treat nausea, vomiting, and dizziness experienced by those with motion sickness. It is not intended for use as a sleep aid even though one of the side effects of Dramamine is drowsiness. 

Dramamine and other antihistamines are commonly used as over-the-counter sleep aids because they are readily available.

While feeling sleepy may be a welcome side effect for someone with difficulties falling asleep at night, there’s no evidence that Dramamine is effective as a long-term sleep aid. 

How does Dramamine work?

Dramamine is an antihistamine that works to reduce the effects of the natural compound histamine in the body.  Histamine is a small molecule abundant in the body; its most well-known function is its role as a mediator of allergic reactions.

Dramamine is actually a combination of two active ingredients:

  1. diphenhydramine 
  2. 8-chlorotheophylline.  

Dramamine’s anti-nausea effects are thought to be a result of diphenhydramine’s blockage of histamine receptors in the vestibular system. 

The addition of the stimulant 8-chlorotheophylline was meant to counteract the sedative effects of diphenhydramine.


 Can I use Dramamine as a sleep aid?

About a third of Americans deal with insomnia each year and are looking for just about anything that they can take to get more sleep. 

Extended disruptions to our sleep cycles can be stressful and frustrating, so it’s easy to feel drawn towards seemingly simple solutions. 

At first, Dramamine may seem like it works. But over a relatively short period of time, your body will develop a tolerance to the medication. 

Also, Dramamine and other over-the-counter antihistamines, such as Benadryl, do not contribute to better-quality sleep when used as a sleep aid.


Serious adverse effects of Dramamine

  • Chest pain
  • Decreased alertness
  • Difficulty urinating
  • Convulsions
  • Seizures
  • Agitation
  • Food changes
  •  Fast or irregular heartbeat

The bottom line is that Dramamine, while effective for motion sickness, is not meant to be a sleep aid

Researchers from the University of Colorado specifically note that “sedating antihistamines do not adequately address the problem [of improving sleep quality and length].” They also said, “the belief that nighttime sleep was aided by the addition of a sedating […] antihistamine was not supported by [a scientific study].”

People who are experiencing sleep problems should talk to a sleep specialist in order to relieve their sleep issues to get more restful, better-quality sleep.
