I took an Alavert the other day and it made me feel really good, very alert and it also helped a lot of with anxiety. Interesting. I wonder why this happens? My friend said she took a Benadryl before going in to surgery and it helped calm her down a lot. Has anyone had anything similar occur with anxiety by taking an antihistimine?

older antihistamines usually sedate as a side effect and were popular as tranquillisers until valium came along, the sedation varies a lot from 1 to another person, feeling hung over all the next day is an occasional side effect

I experience frequent anxiety. Last month I had a bad head cold, and bought the generic form of Claritin at Walgreen’s, in order to clear up my sinuses. After taking it, I found that my anxiety was greatly reduced.

Doing research online, I have read that some types of antihistamines are used to treat anxiety. However, nowhere have I found that loratadine (the active ingredient in Claritin and Alavert) is used for this purpose. In fact, in some people, antihistamines actually increase anxiety.

I am glad that it’s worked well for me…has anyone else had a similar experience?

Hi I just came off of an antidepresant called remeron ( mirtazapine ), one of the things in it is an antihistimine . Definately helped me with my anxiety and I slept like a baby every night. But the down side was that it made me eat like a wild animal :( So yep I would definately believe that they would reduce anxiety :)

Yep antihistamines do increase anxiety for some they do that to me.I will have palpitations and feel on edge after taking some cold meds

remeron is different from an antihistamine

Yep Im aware that remeron is different, but it does have an antihistimine in it :)
