Histamine is necessary to promote wakefulness, motivation and goal-directed behaviors; when the receptors for histamine are blocked, drowsiness occurs.
Many companies have marketed diphenhydramine and doxylamine (another sedating antihistamine) for insomnia under different brand names.
Insomnia is characterized by difficulty getting to sleep at night.
The condition affects millions of people all around the world.
Aside from the obvious (dependence, sedation, tolerance, etc.) what are the long term effects of using antihistamines as sleep aids? I had to stop taking it due to the weight gain and other side effects. Trying to do the work out thing to tire myself out. I don't know anyone who has taken it that long as a sleep aid but i know one person who took huge amounts of diphenhydramine for allergies (hay fever and such) over a period of atleast 6 months.
The thing is ever since i cleaned my act up rehab sent us all home with scripts for seroquel for sleep.
Drowsiness is one of the major side effects of some antihistamines, such as diphenhydramine (Benadryl) and doxylamine succinate (the antihistamine found in Nyquil).
On one occasion this person needed to be hospitilized with a allergic reaction of unknown origin and the hydroxazine and diphenhydramine drips barely helped at all.They also make blood vessels more permeable, allowing proteins and white blood cells to seep into the damaged or infected tissue.But there are side effects to this healing process.There are many different types of sleeping tablets available on the market.Here, we will look at two kinds of sleeping tablets that are used to get relief from the symptoms of insomnia.
