<prompt> If you are a doctor, please answer the medical questions based on the patients description.my blood pressure was 150 over 100 yesterday and i took two cozaar pills of 25 mg each. today its at 149 over 96 should i go to emergency room? i am prescribed to take one 25mg pill daily and this was working until a couple days ago when they switched me from losartan to generic. now i am vomiting and my stomach s upset.  <response>: Your blood pressure is definitely not an indication for the emergency room. The change to generic is a very unlikely source for vomiting. Blood pressure recording should be done routinely and not sporadically. Single measures should not prompt concern. Decisions are best made from an average value from a two-week span. Record your blood pressure on a schedule every day. It should be taken seated after a 10-15 min period of relaxation. Your goal depends on any other problems you may have. In general, it is an average systolic value 150 and diastolic 85. When you meet with your doctor again, bring the record to help determine the need for adjustment.
