Hi. I am visiting US from Slovakia, I am 72 years old. I have a hypertension and I am on 4 medicines: Lokren (dosage 1/2 tablet), Gopten (trandolaprilum 2mg), Rawel (indepamidum 1.5 mg), Agen 5 (amlodipin) which I ve been successfully taking for over 20 years. But my pressure has drastically dropped last couple of days while here visiting. I used have 130/75 and pulse 65 on the medicine and now it went down to 106/58 and pulse 56. I also experienced vertigo. Please advise which of medicine(s) I can safely temporarily stop taking while here visiting, to get it back to my old normal without endangering myself. Thank you
