For High Blood Pressure "Male, 53, regular exercise, healthy diet. Started losartan (Cozaar) 2 weeks ago due to high blood pressure. Dropped the blood pressure first day, but still is high - before taking BP was 160's / 110's, now it's 140's / 90's. Noticed frequent urination - like every 15 minutes. I canceled an international vacation because of this. Then came the anxiety at night. Never had anxiety this bad - ever. Finding myself locking the doors, checking to make sure they are locked multiple times. Slight confusion and short-term memory problems. Yesterday bought a $1500 large screen TV that I really did not need and does not even fit on our TV stand. Numbness in one thumb. Dizziness - almost fell backwards off of stool at restaurant. Giving it one more week."

For High Blood Pressure "I have had high blood pressure for years and have just started a medicine routine. I tried Zestril and had great results but did not like the cough. So, my doctor switched me to Cozaar. This makes me cough, makes me tired, dizzy, and constipated."

For High Blood Pressure "I have been taking generic Cozaar for about 3 months. Taking 25mg once a day along with 12.5 mg of Hydrochlorothiazide. It mildly lowers my BP. I get readings near 120/80, but also get high readings sometimes as well. The doctor wants to up the dosage to 50mg per day. I want to wait a while as my blood pressure isn't that bad yet, and I am trying to slowly adjust to the side effects. I am constantly 'dry' and thirsty for water. I have bad dizziness that gets really bad on occasion. The side effects are much less for me than Lisinopril, which had me coughing 24/7 and gave me bad angioedema after 3 months."

For High Blood Pressure "I've been taking this medication for about 1 1/2 months or a bit longer. I have been having a lot of bowel movements, stomach discomfort, went from weighing 123 lbs to 98 lbs, not to mention feeling dizzy and fatigued. I just left a message with my doctor's reception desk, and I'm hoping I get a call back today with a reply to my message."

For High Blood Pressure "Cozaar 25 mg was effective in reducing blood pressure, but very expensive and possibly caused dizziness. It was replaced with Amiodipine Besylate 5 mg (generic for Norvasc), and it works just as well at a much, much lower price. Dizziness has eased."
