I m a 63yrs old male having high bp and taking envas-5mg twice a day for the past 7 years. Past 7 years my bp was stable at 140/90. I m taking no other drugs. I am not a diabetic and have no other problems.lipid profile within normal range. my question is whether there is any side effects with continuing envas or should i have any other medicines. Looking forward for your expert advice.
