I am 64 years old. Despite a low risk profile
Hi, Nevibilol and perindopril belong to two different class of blood pressure medication had its own benefit and side effect profile.  As per my understanding, there are certain aspects of why you want to shift to Nevibilol. Let me explain each.  1) Fall in pressure, maybe titration of perindopril dose would be more appropriate. Decreasing the same may help. 2) Tremors, Nevibilol is a beta blocker with intrinsic sympathetic activity, so though beta blocker as a class helps reduce essential tremors, Nevibilol may not help much.3) Libido, though Nevibilol is marketed as causing the least loss in libido, for sure it doesn't improve it.  Also, it's a company-sponsored trial, so how much to rely on is a problem.  Lastly, Perindopril has never been associated with loss of libido, so your problem may be completely unrelated and so changing medication may not make that big a difference.  For sure Nevibilol is heart protective but so is Perindopril. So I think your doctor would be in the best position to select which medication would be best considering your individual characteristics. Hope I have answered your query. Let me know if I can assist you further.
