nasal congestion
"Have had lifelong issues if Allergies and Sinus Congestion/Infections.  This is the first thing that has worked.  Only use the 12 hr formula taken early in the morning.  24 hr didn't allow me to sleep well.  Noticed a higher heart rate/jittery feelings for abt the first two weeks, then my body got use to it.  This med has improved my health and allowed me to stop taking multiple meds that could not provide the relief that taking one Claritin D has."
