I have been taking "benadryl" for 22 yrs. and basically is my allergy pill of choice. 12 years prior I had shots as I was on very heavy prescription antihistamines (none of which I can recall, being over 34 years ago.) They made me "foggy" on days of high pollen, mold, etc. counts. Therefore I tried the pincushion treatment. After 12 years I was able to rely on many OTC drugs. When I realized that lactose was used as a filler, after testing positive for intolerance, I stopped experimenting and have relied on "benadryl" by label or generic since. I was recently told (by an MD) that my high blood pressure could be caused by it. I thought this was ridiculous, being a sedative. Or having sedative effects...I have been losing weight (from 215 to 185/5'6") as I believe it to be the underlying cause to the hypertension. Please tell me your opinion. I cannot find anything even anecdotally that would support this opinion.
