I have been suffering from high blood pressure for several years and treated successfully with 50 mg of Losartan. A few months ago my BP was low so the doc took me off them. It has risen since then so I started taking the Losartan again but found that it was now making me breathless so I stopped again!! I had my BP taken at Docs this morning and it was still high (today 160 over 80) and the new doctor I saw wanted to up my Losartan even though I explained I hadn't been taking it for a few weeks. He gave me a prescription for 25 mg to add to the 50 mg. Two questions - as someone who is Hypo and 60 years old, is 160 over 80 (plus cholesterol of 6.7) something to really worry about? Also, if I do start taking Losartan again I will start at 25 mg and increase to 50 after a month if breatlesness goes - is it OK to take at night when I take my Levo?
