COZAAR  (LOSARTAN POTASSIUM):  Losartan is used to treat high blood pressure (hypertension) and to help protect the kidneys from damage due to diabetes. It is also used to lower the risk of strokes in patients with high blood pressure and an enlarged heart. Lowering high blood pressure helps prevent strokes, heart attacks, and kidney problems. Losartan belongs to a class of drugs called angiotensin receptor blockers (ARBs). It works by relaxing blood vessels so that blood can flow more easily.   FDA Approval Date: 1998-10-13 (Sources: U.S. Centers for Medicare Services, FDA)

 1  high blood pressure Light-headed, fast heart rate, ears ringing. Not lowering my blood pressure at all. Nifedipine XL 60 mg and lisinopril 40 mg had been controlling my blood pressure well. The doctor changed me from lisinopril to losartan because of the annoying cough caused by lisinopril. Now my diastolic has shot up to the mid 90's, heart rate over 100, and my head and neck feel full of pressure. I'd rather put up with the lisinopril cough than have a stroke. Useless medicine in my case. F 64 3 days

 2  HBP I have had an increase in BP while on 50 mg and Dr increased to 100. Now, ankles and legs oedematous and skin feels tight. I see Dr. Next week and going to ask to go off of this med. I have never had problem with Linsinopril except for the nagging cough which I would gladly trade for this uncomfortable edema and chest uneasiness which I never had before. I do not care for this med. I feel worse on it than I did before when on Prinizide. F 59 1 months

 1  blood pressure Severe vertigo every time I laid down. Quit taking it and went to doctor. He said the vertigo was just a coincident and not the med. He said to start taking 1/2 pill once the vertigo quit. I knew I shouldn't take it again, but I did when the vertigo stopped after 2 weeks. 2 days after I started again I had vertigo that lasted even longer - about 6 weeks. I also developed labyrinth that lasted for months and I still get it on and off. I'm still scared to lay flat down and sleep elevated a year later. Would NEVER take this medication again F 44 3 days

 2  high blood pressure Body feels HUGE. Restless legs pain in knees and lower legs. Started on 100mg got a rash, severe itching, hair loss, no energy. Dr cut it back to 50mg and no improvement getting worse. Used to work out 3-5 times a week. Now lucky if I can stay in the elliptical for 15 minutes. If I skip this medication for a day, I don't feel as swollen until about 5 or 6 hours after I take it again. Insurance will no longer cover divan but I am not staying on this. F 60 7 months
