Wow, very scary...very. I would say her meds need to be cut back. Esp. if she is averaging those types of blood pressures. BP meds. can easily be adjusted. does she take her BP meds in the AM? I know typically with hypertension, BP will drop after the meds are taken, but can go up later on, but if she is staying that low...her Dr. needs to do some re-adjustment of her meds if not take her off some of them. If he doesn't, I'd get a second opinion because anyone who is getting that low where I work, the meds get re-adjusted. I see where you said her BP is each morning before she takes it...that low she shouldn't be taking it if at all very little. If she was dehydrated, that can drop BP and then it's liek the meds are "concentrated" in the blood stream, in simple terms, but it sounds like the Dr. needs to take her some meds or really lower the dose. 114/74 is a perfectly fine BP....even if she was in the 120s or so, that's fine to! Let me know what the Dr. does.
