Along with the meds the pharmacy sent a kit with instruction booklet and some medications for diarrhea, vomiting and dry skin. These aren't problems I'm having though.
What I have is occasional dizziness, shortness of breath, and a couple of recent headaches. The booklet says these are signs of raised blood pressure, and indeed it was higher on my last hospital visit (130/95 instead of previous 120/85). For now it seems they are taking the wait and see approach with that. Meantime I need to get a home test kit.
