What Causes Raised BP And Heart Rate After Nasacort Intake?

Just tried Nasacort for the first time. I have had a blood pressure spike at 196 / 84 heart rate 80. I do react to antihistamines that way in some cases, but this seemed to be a cortisteroid and not related. Have you heard of this reaction? I also react with a blood pressure spike to MSG, which seems unrelated. Thanks for any response.In Christ Jesus Steve Van Nattan Texas
