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  blood pressure I took cozaar for three days and the back pain was so severe. As a matter of fact, my back continues to hurt and I no longer take this prescription drug. I also felt sluggish and my sinus were swollen while taking this medicine, and it affected my eyes. I have not been able to get back into my routine sleep pattern after taking this medicine. On the plus side it did lower my blood pressure. I would not recommend this medicine. F 42 3 days

 3  High BP I am not sure if it is caused by Cozaar but have started a ringing in the ears which I have had checked and nothing wrong. I have read some of the comments and am wondering if the pain i get in my knees and hip are because of it. I am also experiencing hair loss and doctor took me off 1/2 tablet atenolol. Weight does not seem to go down even though i am exercising and keeping a watch on my diet! I was on Diovan first but when I switched insurance companies, they would not prescribe it to me. I did not experience any of this on Diovan. With Cozaar my libido is almost non-existent! F 56 3 years

 4  hbp back/hip pain possibly----Dr. never said it could be related to this medicine. Makes me curious. Lisinipril made me cough. Cough did not go away immediately with cozaar, but eventually subsided. HBP is back to normal now with cozaar. I also take digoxin for irregular heartbeat that i've had for 20 years. Cozaar is very pricey, even with my rx discount. F 46 3 months

 3  High blood Extreem fatigue, low libido, irritabillity, sore heel joints, light headed... most of what others are saying, but with different degrees of seriousness. It would appear that the side effects have different qualities for different people, BUT there are some side effects which seems to be a common denominator to most users. This means that there are valid reasons to be sceptical and aware of the dangers. I am looking into weaning myself off this chemical drug for something called Preasure-ease. More natural M 53 5 years

 1  HBP Warm feeling in feet after 3 days of taking 100 mg. Stopped taking for 4 days and experienced severe fatigue. Started taking again and side effects got worse. Here are a few- insomnia, anxiety, rapid heatbeat/fluttering, severe depression, nightmares, lack of concentration, loss of sex drive and erection, sweats, rattling chills, severe headache and neck pain, stuffiness, choking sensation from a feeling of having a finger down my throat which caused nausea. Side effects not all at once. Some would dissipate for days then return. The longer I was on it the more intense they got. I can't handle the anxiety and depression. I feel like I am literally losing my mind. I want to sleep it off but I can't. What a miserable experience. I am scared to take anything else. I think I'll become a vegetarian, cut all salt and exercise like CRAZY! This medicine was given to me as a sample. This medicine, to me, hasn't been researched long enough. M 31 4 weeks

 4  hypertension angioedema- my tongue, eylids ,lips were a little swollen, and I have muscle pain. Then my tongue started having little cracks on it, making it painful to eat or even drink anything. THis lasted about one week. My doctor said once I did not have any airway obstruction it was ok and that my tongue will heal and it did. I remained on cozaar because it's managing by bp well. I'm now 117/70. For now it's doing the job, unlike norvasc which caused my upper and lower extremeties to swell. F 43 5 days

 3  mild hypertension Fatigue, joint pain, muscular aches No side effects when starting dosage, and it works to lower b/p. Side effects seemed to "sneak up" on me after 6-7 months. Stopping dosage for even a short time relieved s/e almost immediately. My dosage was very low..1/2 25mg/day M 72 9 months

 5  Hypertension For the initial 2-3 weeks after starting cozaar I felt like i might have been experiencing some mild adverse mental effects like drowsiness or cloudiness. However I am also on beta blockers, and I changed from a different medication. This could explain the cloudy feelings. No other overt adverse side effects. The only issue with the medicine is that it won't be available in generic form for at least another 2-3 years. I'll go broke. I think alot of you guys that have these crazy side effects are hypos. I think you need to get a doctor you trust, and give the medicine clear, objective consideration before discontinuing. If you don't take the medicine, there are far greater consequences than being tired or having diarrhea... like death. It's been 1.5 years since i started taking cozaar. If I take Cozaar at night, I sleep better. If I take my dose about 1.5 hours before I plan to sleep, it's easier to sleep. For the longest time I had pretty bad palpitations. When I started taking cozaar, they diminished and they're basically gone now. This could be purely coincidence. For the most part, my blood pressure is stable, with no big spikes or troughs in between or just after taking the med. On an even more positive note, I read in some studies that cozaar was beneficial to people that have brain diseases like parkinsons or alzheimer's. I also read somewhere that people who take cozaar have "significant increases in sexual satisfaction" -- whatever that means. I haven't noticed. M 24 1.5 years

 3  High Blood Pressure I guess from reading all the replies here that my dizziness is probably a side effect of the drug. I started researching about Cozaar today because that is the only thing that is different in what I due or take on a everyday basis so I had figured to start there and while reading on here I basically come to find out that it is most likely from cozaar. I also realized that I have some tiredness (although not extreme) in trying to wake up in the morning and it is harder to "get out of bed" then what I can remember. I've had some palpatations, but very rarely (only if I rush and loose m breath I get a few "miss" ticks of the heartbeat that I can definetly recognize) I have been on Cozaar 100mg for almost a year after having some of the same side effects by taking Hydroclotothizede 75mg last year for about 1 yr time. Initially cozaar worked great (went from 50mg to 100mg) but as the summer started (in AZ) just like with Hydroclorthizide I started feeling real dizzy. I had a bad episode July 5th where I woke up for work and took a shower and had what I would describe as a TIA (although my doctor and the hospital did all the tests and it all came back fine, even though you can't really test for TIA since there is no "damage") where my left arm went completely dead for about 30 sec and it fealt really sureal (no pain, no loss of consescnous, no confusion, etc)and that really scared me. I think it really had to do with cozaar. My dizziness is not everyday and I would describe it as having episodes where it will run for a few days and then go away for a week or 2 and come back. I split my dose to morning and night 50mg each and that seems M 37 1 years

 1  to protect my kidneys from diabetes long time living with very low blood pressure, 90/42, the dr. kept telling me the lower the better. needless to say i finally awoke from my trance and insisted that i would not take it. i am myself again, my blood pressure is 120/60 more or less. also changed drs. so disappointed at the care i didn't receive. be careful, check your drugs, take your blood pressure yourself.

 2  High Blood Pressure Light Headiness, Dizziness, Disoriented, Fatigue, Muscle weakness, Extremely winded after 5 minutes of cardio exercise. I took 25 mg for 4 weeks. My blood pressure remained elevated. I started 50 mg for 2 weeks and my BP varies. I run 3-5 miles almost every day for the past 6 years. Now, I feel fatigued and weak after 5 minutes of running since I started Cozaar and simultaneously started Lantus Insulin for Diabetes 2. I checked my blood sugar levels and they were not too low. I'm not sure if my body needs more time to adjust to the 2 medications. F 50 6 weeks
