I have allergies 6 months out of the year (April - October in southern California). I have used loratadine on and off, but never more than a few days at a time, because I usually avoid medications whenever possible. I am wondering about the long-term effects of loratadine (i.e. taking it every day for 6 months)? Do the side effects increase with continued use? Can it do damage to the liver or kidneys?
