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)

 3  high blood pressure lightheadness,dizziness,anxiety,depression,tingling in my arms and legs,fatigue I went to see my doctor because I was feeling depressed and not at all my normal self. He told me that depression was rare with Cozaar and to keep taking it for a few more weeks to see if the side effects disappeared. I was glad to find this site as I was thinking that my symptoms were perhaps due to menopause. I can't wait to get off this medication, but I don't want my blood pressure to creep back up. I will definitely give the diet and exercise a good try! F 50 2 days

 4  4 Occasional light-headedness, dry-mouth. Better than lisinopril which made me cough all night. I do seem to also have water retention in my legs - which my cardiologist cannot see, but I can. Helped to reduce my heart palpitations. Glad to see this site because I've been worried about the water retention. Also, migraines with flashing lights - sometimes two or three episodes in a row for several days in a row. Helped libido and I'm not as tired as when I was on the lisinopril. It lowered blood pressure, but that seems to be creeping back up. I'm trying to lose weight, but I have about a 5 pound water weight gain that goes up and down. Don't know what on earth to do - lisinopril was horrible. Will really try to lose weight now to get off this stuff - esp after reading all these comments. May God help us all! F 50 1 years

 1  HBP Arm/bicep pain; right knee pain radiating up and down leg causing a restless leg-type situation; agitation. (Pharmacist and doctor assured me that the Cozaar didn't/shouldn't cause this problem. My leg was hurting so badly that I went to an orthopod, had an MRI, and was diagnosed with a miniscus tear. The surgery to repair was performed within a few days.) I took the medicine for 5 days, decided on my own to come off. It took 48 hrs. to totally exit my system. F 58 5 days

 3  High Blood Pressure Fluttering in my chest (heart) wakes me up at night. Mild dizziness, though nothing like I had on Hyzaar, which I switched from. Some fatigue Not sure abotu this drug. I was prescribed it at 50 mg as an alternative to Hyzaar, which just about did me in (talk about side effects!) I've only been taking it two or three weeks, but I'm considering stopping it. F 47 3 weeks

 1  High Blood Pressure Side affects took a few weeks to manifest to the extreme. Extreme muscle weakness and pain, joint pain, nausea, dizziness, weakness/fatigue, pain in left kidney, heart flutters/spasms, headache. I got to the point where I could barely walk up the hill! The side affects of this drug are very scary. I figure if it affects your body's muscles in a negative way, it must affect the heart muscle also! I haven't been able to find any blood pressure medication that doesn't have horrible side affects so far!!! F 3 weeks

 2  border line high blood pressure Dry mouth, hip pain,foot pain,chills,frequent urination in night,heart feels like fluttering,always tired,ringing in ears,heart races,pulse drops. Was previously on Linisapril in which I had also side effects, my Dr. switched me to cozaar which helped but now having these side affects with this drug. I am on 50 mg and am 49 years old. Bp was 139/89. Now with cozaar it is 128/84. I do not think drugs are tested enough to show any dangerous effects from them. The drug companies seem to be only interested in the huge profits these products produce for them in the short term. disregarding the affects it has on people. M 49

 4  For Blood Pressure I have been taking 100 mg of Cozaar for over five years and have not had any side effects. Or maybe, since I have been taking 100 mg for so long that I do not realize that I may have any side effects. However, in order to reduce my Protein, my nephrologist read about a study where increasing Cozaar actually reduces Protein. The game plan was to increase the 100 mg to 200 mg for two weeks and then do a 24 hour urine. The doctor said that there would be no side effects. After the 7th day of 200 mg all of a sudden my urine turned brown and a tea color. I was immediately taken off of the Cozaar and my BP was about 108/50. My BP is back up to normal after two days but the jury is still out on what happened. There was no blood in the urine and all blood work, urine and EKG were normal. The M.D. is now researching this as to what may have happened. I just hope that I did not lose any kidney function. The creatine level did not go up M 67 7 days

 2  high blood pressure extreme fatigue, drowsiness I'd complained to my doctor over the last couple of years about being extremely sleepy during the day. We never connected this with the Cozaar, but instead kept changing my antidepressant-- with no effect. I switched from Cozaar to Norvasc about 5 months ago to save money (Norvasc is much less expensive) and am no longer drowsy during the day and have much more energy/motivation in general. I have noticed the extreme difference as have my friends and coworkers. F 45 5 years

 4  High Blood Pressure Weight gain. It worked well to reduce my high blood pressure, but I could not keep up with the weight gain. Although I exercised regularly and ate a healthy diet, the weight kept piling up. I gained 15 pounds in two months. F 60 days

 2  High Blood Pressure Gradual weight gain, headaches, depression, mental confusion/dullness/not being able to concentrate, fatique, sleeping 12 hours at a time, general malaise feeling, leg pain/swelling, blurred vsion, dizziness, trouble sleeping at night and shortness of breath. It does seem to control my blood pressure but at what cost? I can't stand the side effects. My doctor says it is not caused by Cozaar, but what else could it be? It's the only med I am taking! I am going to try the natural route, exercise, eating right, vitamens, herbs etc... and see what happens! :) F 56 10 months

 1  HBP I am on COZAAr again :-( I have failed to do the much needed exercise I had started back in junly, this due to too much work and my BP was somewhat very high. Doctor says I have to take or other med. I decided to give it a another chance, but I am back to the old side effects: cough, not sleeping well at night, dizzyness, very tired, forget things, get often more upseth with the kids and family, etc. I take it in the mornings right I stay up, 06:30/07:30 the doctor says is the best time, I have tried it at different times of the days, if I take it around noon (12) then I will have a hell of a day, complaining and upseth the whole family and or coleagues, I will have no fellings for no one, comments are though sincere which does not work in the real world now. Although sexual activity is the same or more actualy, and it is the same as last time, but off course I won't get much from the wife, while going around making lives difficult here at home :-( I try to controle it but can't get to This is an update to early statements: Not satisfied with the drugg COZAAR, I have been on it since 2006 with a pause between july until 10/1/2008, doctor syas I have to take it or other stuff, since i had already I starte it on it again to give it another shot. Side effects are the same like last time, and again feel depressed and pain in the chest and stomach, dizzy and forget things. I explained to doctor all my side effects and doctor just laughed, It fels like she was happy I had to crawl back to the drug, since i failed to the planned training activity, but private work matters, makes the situation impossibel to train at he moment. Doctor doesn't believe my side effects are due to the drug, even i tried to shoe the results on this webpage, she just laughed at my face and said that off course there is always people outthere complaining about COZAAR, but it doesn't help me much complaining back. :- I had a BP unit recording for 24 hours, and it came with a few high results (60%) s M 41 3 years

 1  High BP I have a BP of 135/100 give or take 10 points at times. I was taking avalide and had dramatic increases to my heart rate, my normal was around 65 went up to 100. Also caused fatigue. Dr. gave me Cozaar, 50mg dose to try. It got my BP down to a normal range, no High pulse rate, BUT headaches every day. I woke this AM and the knee pain was extreme. Only painful in the right knee. This was after a restfull Saturday without any exercise or work that could cause the hobbling. I've got to go off of this, am going to try something else. M 58 21 days

 1  High Blood Pressure My doctor (cardiologist) wants me to take 100 mg of Cozaar each day. My blood pressure is 135/90. Thank you so very much for your comments and experiences with Cozaar. I will NOT take it. I have decided to greatly reduce my caffeine and alcohol consumption, excercise regularly and lose some weight! M 56 0 days

 5  Hypertension Works wonderfully for me. Was looking for something with no/low sexual side effects- my brother recommended Cozaar as he takes it with no negative side effects. Had taken several meds before this with icky side effects- Lisinopril- cough, Beta blockers- zonked, tired, out of it... etc. This has been great for me. Only question I have is does it effect memory- but my (mild) issues may be unrelated to this med, who knows! F 52 2 years
