Hi, My father is aged 56 and he is hypertensive. He was using the antihypertensive medication for the last 6 years and it the BP is well under control around 120/35. It was also confirmed by his physician. He was not ready to take him off the medication. Whenever my father asks about it the doctor says Not now, donâ€™t worry about it I shall listen to you when the time come.Can anyone tell me how long the antihypertensives are used if the BP is brought under control?
