It didn't work! My nose still ran...could just be my nose. I've tried many products. Claritin--12 hour always worked for me but I can't get it anymore. Now all they have is the Claritin 24 hour and that does not work. The Claritin 12 hour worked great. I've even tried the 12 hour behind the prescription counter and that doesn't work. Only the 12 hour behind the counter.
