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  Protect Kidneys from diabetes At first I was on 50mg and verything was going fine. The micro protein levels were being reduced as we wanted. They were high because I was diabetic for about a year and didn't know it and wasn't getting treatment whatsoever. I sent 3 days without taking it one time and was having horrible dizzy spells and palputations. The DR later increased it to 100mg. After about 3 months, I find my erections are not what they use to be and I have had trouble maintainig one recently. I only takle cozaar and metphormine. The mephormine has not changed in 2 years and I didn't notice any problems until 6 months ago. This is really concerning me I'm thinking that 100mg may be too much for me. I've researched it on line and find there are some people that have reported similar effects on their erections while on the drug. But, there is a guy on here that says his got stronger. I don't know what to think. Any thoughts? I see my DR tomorrow and will probably ask him to drop the dosage. M 37 2 years

 4  Mild heart attack, high bp lower back pain, upper back pain near neck, sinus infection/sore throat Blood pressure averages around 110/70, taking it along with Verapamil 480mg. BP was about 140/90 before adding Cozaar although I stopped smoking when I started taking Cozaar. Would like to hear from any others who are experiencing similar side effects. M 55 3 months

 3  High Blood Pressure Increased Urination, I am taking it along with Coreg (6.25 mg 2x) My BP is ok but I feel drowsy and somnolent many times F 73 6 months

 3  hypertension Lower back pain which I didn't think anything of at first because I always have lower back pain but this is differnet. Diahhrea, loose bowels at best, GI bloating and lots of gas, neck and headaches, irritable and run down all of the time with achey joints. I am getting tired of side effects. It seems like everything I take for my BP I end up having side effects eventually. Sometimes they develop quickly. Sometimes they take a long time. I've been on Cozaar for about 9 weeks now and these effects came on rather suddenly about 4 days ago. I was on Lotrel for 2 years before I had any effects. I guess my wife is right. The only solution is to lose weight, walk everday and won't need the meds. Unmedicated my BP can go as high as 170/110. With minimal doses of anything it goes down to around 130/80 or less. I am on 50mg of Cozaar per day M 49 9 weeks

 2  Hypertension Chest pain; anxiety previously on Toprol XL, but changed due to joint pain and muscle fatigue. Had allergic reaction to Altace, then switched to Cozaar and am up to 100mg now. Have Developed chest pain after nearly any level of physical activity. Resting pulse varies greatly - from 50bpm to 150bpm, accompanied by anxiety above 100bpm. Obviously need to switch again, but what's next? M 51 21 days

 2  Hypertension At 100mg dosage for hypertension: initial flushing, rapid onset of insomnia, shortness of breath (asthamtic), chest pain, angina pain and acid reflux. I should add that it did lower bp signficantly. Losartan is probably one of the better monotherapies for hypertension available, especially if adequate bp control can be achieved at 50mg. At higher doses side effects appear more pronounced. My negative experience could relate to mild angiodema (which can occur with both ACE Inhibitors and ARB's). I reverted back to Perindopril 4mg for bp control. M 30 1 months

 2  Hypertension / atrial fibrillation Initial dose of 25mg taken for 18 months was fine but when it was increased to 50mgs by cardiologist, I lost 40% of my kidney function in 3 weeks F 59 2 years

 2  High Blood Pressure Severe edema, which even HCT wouldn't resolve, and even higher blood pressure. If you have insulin resistance and a problem with edema already, you should be taking Atacand, but, of course, my new doctor, wanted to try something new. F 43 3 weeks

 2  High Blood Pressure Diahhrea sometimes,neck and occasional headaches, very irritable and sometimes with pain in my joints,lightheadedness & some dizzyness.Strange feelings and pain in my body. I have been depressed for the first time in my life. can't sleep well at night, lots of swet, Insomnia, coughing and difficut to concentrate. Extreme fatigue, dry mouth, anxiety, rapid heartbeat sometimes - yes, LOTS of depression, LOTS of sweats, LOTS of disorientation and drowsiness too. It's so amazing, I'm so glad I found this website too. I have been on Cozaar for 2 years, but didn't make the connection with Cozaar. I have talked to my doctor since the first week, but she told me this had nothin to do with the this drug. I could actually almost writ the most on this page om my side effects. Since I have been taking it for so long, I guess I have been through all of them :-). While I am writing this my left arm/elbow is hurting, I have been felling very strange all day before I came across this site, I will print this out and show my doctor, she can't just say this isn't true.

 3  HBP The first 3 years or so, was okay, now, I suffer from sleeplessness at night and horribly tired and sleepy during the day. I had to cut my work hours to half time because I am extremely tired during the day. High anxiety, dizziness. I had never suffered from depression and anxiety before, now, it is unbelievable. I have been taking 25mg for 6 years now. Since my father died of a stroke, I know I have to take BP med, but let’s see what happens if I take it every other day for a month and start getting serious about exercise. I have already cut at least 75 percent of sodium intake in the last couple of years. F 54 6 years

 5  high blood pressure none - it worked great. I'd been on cozaar for over 5 years to control my wild bp (too high sometimes and too low others; averaged out too high), and it worked great - controled the bp as well as I can ever expect, and no side effects. A recent change in job brought a change in health insurance and of course the new insurer won't cover cozaar, so Dr. is trying others (currently diovan, which has caused insomnia and 5 lb weight gain in 2 weeks). I'm debating just paying for the cozaar out of pocket, despite the high cost. But I'll call the Dr. today and will probably try another drug (atacand?) before giving up and paying it out of pocket. If he'll try hard enough, my Dr. should be able to convince the health insurance company to cover cozaar for me, but I'm not holding my breath - I've been dealing with the medical industry for a rare and little understood condition for over 20 years, and know they don't like to listen to patients.

 2  HBP After switching from Procardia becasue it was ineffective in reducing my Bp, I took the Cozaar for about 2 months without issues. Bp went down from 150/100 - 120/80. Then the daily headaches started. They were debilitating mucle tension type headaches in the back of the head and behind my eyes. Nothing would help these. Went to a different Dr. who put me on Benecar(sp)for a month. After 1.5 weeks headaches went away. After my Benecar ran out I went back on my Cozaar to see if the headaches would return, they did in 2 weeks. Now Dr. is trying Diovan 320 mg. I looked at the side effects for that - holy crap! I will give it a go, but it looks terrible! M 48 2.5 months
