Risks of non sedating antihistamines
Antihistamines are medicines to treat allergic reactions to pollen, dust, pet dander, foods, and drugs. If so, you may take antihistamines to treat your symptoms. Examples include pollen, dust, pet dander, even foods or drugs.Antihistamines are found in many different forms for children and adults: liquids, tablets, creams, nasal sprays, and eye drops. When an allergen enters your body, your body releases histamine.
It can be hard to find the one that works just right.Diphenhydramine is the most common antihistamine used non-prescription sleep aids. Certain antihistamines indicated only for allergies, such as chlorpheniramine (Chlor-Trimeton), diphenhydramine (Benadryl), or hydroxyzine (Atarax or Vistaril) may also be used as mild sleep-inducers.Some drugs contain diphenhydramine alone (such as Nytol, Sleep-Eez, and Sominex), while others contain combinations of diphenhydramine with pain relievers (such as Anacin P. Unfortunately, most of these drugs leave patients feeling drowsy the next day and may not be very effective in providing restful sleep.Antihistamines make your sleepy by antagonizing central histimine-1 (H-1) receptors in the brain.The ones you see in over-the-counter sleep aids are usually diphenhydramine and hydroxyzine.
