I found that steriod nasal sprays induced palpitations, not surprisingly. There is a different class of nasal sprays which are mast-cell inhibitors which have a very benign side-effect profile. It is sold under the brand name Nasalcrom. I use it regularly in the Spring and Summer and have no problems. I also take Zyrtek for very heavy exposure, like cutting grass or hiking in the woods - it works but I prefer not to take it regularly.
There is an interesting history of the pharmaceutical industry attempting to recapture Nasalcrom as prescription drug. I don't know if they are still pursuing it.
