nasal congestion
"After suffering with nasal congestion and trying a variety of allergy medicines, I tried using
Claritin-D.  Although it didn't clear up the nasal congestion, at first I did seem to feel better.
THEN, the side effects started:  extreme dry mouth, stomach pain, headaches, feeling nervous, faster heart rate, constipation, tingly feeling under my skin, insomnia, urinating less than usual;
After quitting the medicine I also had high blood pressure, fear & anxiety (I was afraid to be alone so my grown children came to stay with me several days).  I wouldn't take it again!!!"
