urticaria
"I've  had chronic  hives for years and until  a doctor  in the  emergency room found  exactly what  to do.. within  2 hours,  it was gone. She hooked  me up to  an IV and gave me a high dose of steriods, not the medrol  dose pack. 20 MG 3 times a day  (after I went  home)but she also  gave me Zyrtec  10 mg, and Prilosec. Apparently the Prilosec  helps also. But I still  get hives every  2 months. When I get  hives, I welt up with a rash from  head to toe,  my skin is red as can be,  and it burns badly and  itches , also take lukewarm  baths with a lot of  Epsom salt,and the soap I use for hives attack is home made lye soap! It must be  home made, I'm  curious about  how much Zyrtec  can you  take within 24 hr. Period safely"
