Nasal Congestion
"I have used Claritin-D 24 for 5 years.  I used to get sinusitis all the time.  It was so bad, I usually missed 2-3 weeks of work per year.  I was tested for allergies, but was allergic to nothing they tested for.  I used to take it only seasonally, but as soon as I stopped, I would get sick again.  Now I take it everyday and am very nervous if the pharmacy runs out.  I do experience a few side effects, but have learned to manage them.  For instance, I do not take it if I can&#039;t take it before 10 a.m. otherwise it causes insomnia.  I also have dry-mouth, but have increased my water intake to 8 glasses per day (good for me).  I have experienced joint pain in the last few years, but determined it was due to plantar&#039;s facitis.  It&#039;s changed my life."
