[/INST] Hi There If you have already started with the new prescription and as you have mentioned your blood pressure to be 130/80 which is a good control, I would like to suggest continuing with the Chat Doctor.  As frequent change in BP medicines are not advisable once it's controlling Blood pressure adequately.  Just maintain healthy lifestyle habit along with the meds as that will help you in long term. Good luck  </s>
