My uncle is a diabetic & his diabetes is nearly two decades old. He is taking medicines for the same. Something unusual happened few days back to him, suddenly their BP increased & he began to sweat. After that day, he is continuously having high bp. We reffered to our family doctor for the same & he prescribed these medicines - Depin Retard, Aldeactone, Moxovas, Aten, PrazoPress Xl. Even after taking these medicines for about 20 days or a month, he has gained no relief. Blood pressure is still very high. The range goes to 133/86 and sometimes 170. He was also diagnosed with increased Creatinine in August 2016. He is allergic to sulphor. Rest sugar is under control these days. What would be the cause of sudden high bp and what should be done? Is there any need for admitting him to the hospital? Or any medicine which can be given to him?
