<s>[INST] Hi I was diagnosed with high BP about 6 months ago,and just started taking my meds again 2 weeks ago,I am currently on Losaratan 50mg and I don t think they are working,I am consistently feeling dizzy and out of it,I took another 25mg,but I still get the same,my blood pressure right before I am going to sleep is 133/84,I just want to figure out what s going on with me or if this is normal,please help,I just want to feel better. [/INST] The losartan you started taking is a safe Chat Doctor.  But as you started taking it too late after prescribing. As you increased the dose from 50 mg to 75 mg on your own assuming BP as increased is not advisable. SINCE YOU STARTED ITS ICE 2 WEEKS YOU NEED TO WAIT FOR THE REDUCTION IN BP.AND YOU NEED TO DECREASE TH SALT CONTENT IN YOUR FOOD AND DO EXERCISE FOR 45 MIN DAILY.COME BACK TO 50 MG AND RECHECK THE BP AFTER 2 WEEKS. </s>
