I was really relieved to have found this information. I thought I was loosing it! I am 38 and was having bursts of rage, crying for nothing... could it be menopause? NO! Unfortunately these are not listed for physicians as side effects so my doctor friend then just thought I was nuts.
The vivid dreams were a more positive side effect for me, but seeing things while awake wasn't quiet as fun. So, I'm off the Zyrtec.
I know people are saying we sound crazy, but bottom line is not all medications are for everyone. And we should know about these potential issues so if they do arise we know its the medication and not something else.
