Antihistamines can make you feel drowsy, and therefore help you get to sleep for two to three nights — but regular use of this medication as a sleep aid can actually make your insomnia worse.

Antihistamines make you drowsy by preventing histamines from attaching to cells in your body and causing swelling, itching, runny nose and tearing eyes.

Antihistamines can be found as the main ingredient in many over-the-counter sleep aids. But, these products are only meant to be used for a few nights at the most, like when you can’t get to sleep due to travel circumstances or stress.

Diphenhydramine, which is the primary ingredient in non-prescription sleep aids such as Sominex, Sleep-Eez and Nytol, is the most commonly used antihistamine for over-the-counter sleep medications. Diphenhydramine can also be found in pain relief medication like Anacin P.M., Excedrin P.M. and Tylenol P.M..

Other sleep medications may contain an antihistamine called doxylamine (Unison). Antihistamines used primarily for allergy medications such as chlorpheniramine (Chlor-Trimeton), diphenhydramine (Benadryl), hydroxyzine (Atarax or Vistaril) or cyproheptadine (Periactin) may also prove to be effective as mild sleep aids.

Resistance to the tranquilizing effects of antihistamines develops quickly — so if you keep taking them, they’ll start to lose their sleepy effect. Side effects may include:

  • Daytime sleepiness
  • Memory problems
  • Dizziness
  • Impaired vision
  • Dryness of mouth, throat and nose

Antihistamines for InsomniaIf you have chronic insomnia and you’re searching for a solution to getting a good night’s sleep, don’t depend on antihistamines or other over-the-counter sleep products.

Caution: Individuals with glaucoma, angina, heart arrhythmias or people who have difficulty urinating should stay away from antihistamines. Also, antihistamines should not be taken with nausea or motion sickness medications. Sufferers of chronic lung disease should avoid sleep aids containing doxylamine.
