About six months ago I was perscibed 80mg of Diovan for high blood presure. It did not bring my blood presure down, so the medication was increased to 160mg a day. Soon after I took the higher dose, I had heart palputations,a racing heart beat,severe headaches,ringing in my ears. And still, my blood presure was high. This medicine went in the trash. After two week of not taking Dovan, my ears are still ringing.
