[|Human|] Hi my mum had a stroke a bit over a year ago. all has been fine except for now her blood pressure is high and the Karvea 300mg tablets do not seem to be working anymore her GP doesn t seem to want to put her on anything else so we suggested could she swap to 150mg of Karvea twice a day to see if it worked in keeping her blood pressure down during the evening because that is when it rises to around 190/100. He has agreed to split the dose from 300mg once a day to 150mg twice a day but I am now wondering if we did the right thing or will that raise her blood pressure even more . Do the 300mg tablet and the 150mg tablet release the same amount throughout the day Please help can you give me your advice on this as I need a second opinion
[|AI|]  Hi welcome to Chat Doctor. I understand your query and concern.300 mg and 150 mg release different amount of Chat Doctor. Hence, it has to taken as 300 mg of Area to have adequate good control to prevent future stroke. I advise you to have a baseline 2 dimensional echocardiography, ECG and lipid profile to assess the basic cardiac reserve of your heart. Restrict the intake of salt to less than 6g/day. Regular physical exercise in the form of brisk walk for 20 min a day for 5 days a week is pretty useful.
