I am 49 years by age, 6ft tall, 85 kgs by weight and have been suffering from hypertension for the past 6 years, there is a family history of hypertention and MI.Was on losartan 50mg for quite sometime, then changed to concor 2.5 and then to supermet xl 50 mg and now to supermet xl 25 in the morning and targit 40 in the evening. My diastolic pressure is not coming below the 90/87 mark after changing from losartan 50 mg. After taking Targit 40, ( the change was effected only last week, I have sores in my mouth and a feeling of giddiness in the mornings) Should I revert to a combination of supermet xl 25 and losartan 50 mg?
