I'm concerned about potential estrogenic activity from taking these.
This study mentions an antihistamine causing gyno

also this article mentions estrogen like activity

I found other forum posts mentioning cetirizine being associated with estrogen. How significant is this and would it apply to loratadine (claratin) also?
I also heard these can be harmful for the liver when taken for a while, is there truth to this and is it significant?
Should these antihistamines be avoided medium - long term, or cycled perhaps? If so what would you say is a good time period to take & stop for?
Finally do you have a preference between Loratadine and Cetirizine for allergies?
Thanks
