Benedryl,Zyrtec, and Claritin

Hi Everyone,

I am trying to figure out if taking Benadryl is a good thing or not so good of a thing. I tried it due to constant sinus problems... I felt my sinus problems contributed to dizzy spells. I took it for 2 or 3 weeks and it really helped. However, I gained 10 pounds (diet and activity remained the same) and my blood pressure rose to a level I was not comfortable with.

I stopped taking it and within 7 days my weight is nearly back to normal and within 2 days my blood pressure was normal. I researched it a bit and am getting conflicting results. Some say it is great and helps with herxing - others say although you may feel better that it mimics an immunosuppressant and to stay away from it because it will slow your recovery. I am now confused?

Would Zyrtec or Claritin be a better choice? Should I stay away from all 3?

Thank You
