If her b/p was 245/170 she should have gone to the er. Because that is very close to stroke levels. She would have had a horrible headache and probably been very sick on her stomach.

As we all know, you should never take medications that are not prescribed to you. This is especially the case with blood pressure medications. BP meds are prescribed based off of your severity of high bp and your height and weight. You can easily overdose on someone elses which could have easily resulted in death. If her b/p is high on a regular basis she needs to have her own prescription.

I have had high blood pressure for a few years. I personally have never had "mush mouth". I normally just get headaches. My father in law had mush mouth, but that was due to a mini stroke. She really should be under a doctors care. If her bp was that high it is possible for her to have had a mini stroke.
