I have been suffering from high blood pressure for a long time, subjectively do not re-examine, regularly take 1 tablet of normodipine 5mg and 2 tablets of betaloc 50mg. Recently, my blood pressure spiked 190/100, I was in the emergency room at Thu Duc Hospital (HCMC). Since then, it has been more than 2 months, I have regular check-ups and take medicine according to the doctor's prescription. The doctor also changed my prescription 3 times and the hospital also did a general test, I have essential hypertension. Currently, I am taking the 3rd prescription: Losartan Bivitanpo 100mg 1v pm, Indapamide Diuresin SR 1.5mg 1v am, Carvedilol Cypdicar 6.25mg, morning 1/2v, afternoon 1/2v, Amlodipine 5mg pm 1v. After nearly 25 days of taking it, I measured my blood pressure at home regularly and saw a gradual decrease, at 150/90, at 140/90. I saw that my blood pressure was still high so I was worried. In addition, in the above 4 blood pressure drugs, there are very serious side effects of decreased libido and erectile dysfunction. The doctor asked me how to effectively treat essential hypertension? I sincerely thank the doctor.
