Loratadine
allergic rhinitis
"It was effective for my allergies, however it caused many side effects that are listed nowhere! Depression, anxiety, confusion and sleepiness that was so pronounced I had to pull over while driving. This was the Nondrowsy formula. 
There are 11 other people who had similar reactions in the support in drugs.com group, under the drug name. I'll deal with my allergies rather than end up in the psych ward."
