5	post srroke	none	very benefical in controlling my high blood pressure	M	54	1 years		7/25/2001 Email
5	HBP	I have had a somewhat dry/tickly throat for about a year and a half, it`s like its never quite clear. I have been to my Dr. twice for this and was presribed claritin, then singulair. Neither worked! I was told by my Dr. that this could not be a side effect of cozaar but now I wonder. He would have to send me to ear/eye/nose/throat if I needed more help. Why would he not know that it IS possible?	Works great for my HBP and I can live with the throat irritation but gonna cut my dose in half to 25mg a day and see what happens. Otherwise like the drug...	M	52	4 years 50mg 1X D		7/9/2010 Email
5	HBP	None really.	I changed to the generic drug 2 weeks ago and either because of it (or it is a coincidence) I started feeling dizzy, mostly when I lay down in bed or even when I turn while in bed. Not when I get up. It lasts a few seconds. I plan to talk to my doctor about it. I was on Altace for the previous 6-7 yrs, but it gave me a dry cough, so we tried Cozaar and it seemed to work. I take Cozaar late in the evening and my BP (along with my diuretic pill in the morning) stays around 120/70 or a little bit less (115/62!!).	M	65	2 years 25mg 1X D		8/10/2010
5	HBP	None	before Cozaar blood pressure 170/95, after 1 week down to 120/80, now 115/70 with the same dose, daily exercise, and trying to watch what I eat, no salt	M	47	8 months 50 1X D		8/15/2010
5	High Blood Pressure	I feel a little woozy even when I take it at night and I feel a little fatigue too. Many people said that those side effects will disappear after 2 weeks or something but when you compare COZAAR to other drugs it wins.	My blood pressure was 150/100 and I felt that I have something wrong with my vision. After taking Cozaar now it's 130/85 and I know that it will work better after few days because I just have started to take it.	M	23	6 days		8/30/2005 Email
5	High Blood Pressure	No side effects noted! I'm very pleased and happy with Cozaar.		M	46	2 years		1/11/2006
5	To lower blood presure	no side effect. Tried another drug and it made feel dazzy all the time. Came back to Cozaar now.	Cozaar made my presure dropped from 140/90 to below 110/70. Will try 25mg/day to see how it works.	M	54	2 years		2/6/2006
5	hypertension	none	I am on 100mg and have been for 4 years with no side effects at all	M	55	4 years		6/28/2006
5	high blood pressure for years	other medications were makeing impossible to have sex.with 100mg of cozaar after a years time i always look forward to going to bed at least 3 times a week for sex and she is very happy.she also takes 50mg of cozaar for bp control.we are BOTH 83 years old	only side effect is a runny nose once in awhile.	M	83			10/29/2005 Email
5	hypertension	None	I took 50 mg for 6 yrs, still had high numbers. Doc upped me to 100 mg, numbers looking good. Interestingly, very first night on 100mg, slept like a baby and that has continued for 3 weeks. Sorry for you folks that have experienced insomnia!	M	47	6 years		7/14/2006
5	hypertension	Cozaar really suits me. Bofore cozaar i have used lot of other medicines to reduce my b.p. but all of them had given me side effects.	i am using cozaar 100 mg for the last7 years. It has given me a good help to drop my blood pressure.	M	58	7 years		4/6/2007 Email
5	High Blood Pressure	None. Great if you've been taking BP meds that cause Impotence.	Hope that your Meidcal Insurance covers this drug.	M	48	2 years		4/28/2007
5	hypertension	no side effects at all	blood pressure went from 150/95 to 125/75 in 28 days tried ace, and betas with no results in my high BP and bad side effects gave cozaar a try and im very pleased with it after trying several other hypertension meds... my reccomendation is to give it try and see if it works for you	M	48	28 days		2/24/2006
5	High Blood Pressure	Slight dizziness and cough that went away. Substantially increased libido and have not needed ED medication since.		M	55	2 years		10/17/2008 Email

5	HIGH BLOOD PRESSURE	NONE		M		2 years		9/12/2004
5	blood pressure	None	This drug really worked very well for me in lowering blood pressure without any side effect. I have tried many other types of blood pressure drugs and all had bad side effects.Cozaar is the only one I can use.	M	61	6 years		2/25/2004
5	HIGH BLOOD PRESSURE	NONE	VERY GOOD DRUG WITH LITTLE OR NO SIDE EFFECTS	M	44	5 years		2/5/2007
5	hypertension	none		M	51	3 years		11/19/2002
5	BP was high	A small cough and minor joint pain, but nothing alarming. Remarkably, my libido has increased and I'm having less prostate -- less peeing at night -- hassles. (Probably a placebo effect, but that's okay with me.)	This is a remarkable drug. Started with 50MG in the morning; MD suggested a jump to 50MB twice daily until BP is stablized. BP is now in normal range and I'm drop back to 50MB daily.	M	60	4 weeks		2/14/2007
5	Hypertension, Kidneys	None, actually	The throbbing pain in my kidney stopped only after a few days on this. Brought my BP down in only a week. (Along with other drugs and loop diaretics). With Diabetes and very high blood pressure my kidneys were working overtime. Now I feel the difference with this medicine.	M	45	1 years		4/23/2005 Email
5	bp	none	I was given Lotrel for BP in the 160 over 95 range and about died from the dry hacking cough, no sleep, vertigo, that came with the drug. I have never taken any prescription drug in my 39 years,only a once a year tylenol or other aspirin and plenty of beer. I am hoping to get off of Cozaar but so far I am pleased with the results. Wonder if some people are just looking for a miracle in the other responses!	M	40	6 months		5/17/2007
5	High Blood Pressure	None. One of the main reasons I rate this drug a 5. I have taken a number of others and think its great.		M	49	2 months		1/20/2008 Email
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		1/6/2008
5	High Blood Pressure. Hypertension	No negative side effects after 4 months use. Feel more relaxed, less agitated. Sleep good. BP is now typically around 124/75 . New Doc recently increased dosage to 50mg 2x/day vs. 1x day 'to provide added protection for kidneys"...????		M	58	4 months		3/31/2008 Email
5	high blood pressure	none	I have been taking this med for a few years. No side effects. It has helped me to lower my BP. I take 25 mg every morning and evening (50 mg total)>	M	67	5 years		11/5/2008
5	Upper reading was always above 160	headache, throbbing sensation in top of my head.	I have been taking cozaar only 5 days now at a strength of 50 mg. od. This to be increased to 100 mg after two continuous weeks on medication.	M	60	5 days		12/28/2008 Email
5	hp	none but if all the people have so many problems thats what there doctors gets paid for. talk to him or her.it took me a long time to find a drug that works. been taking it 4 years		M	58			9/7/2008 Email
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		6/14/2008 Email
4	high bp	The only real side effect has been diarrhea that started a few days after first starting on cozaar. BP down from 171 over 94, to 123 over 77 at its lowest. Average bp around 133\80. Cozaar has helped, just hate the diarrhea!		M	38	2 weeks		8/25/2008 Email
4	high bp and diabeties	Lasinapril like cough showed up after 2 months. Dizzy spells limited driving a car. Reduced dosage to 25 mg did not reduce symptoms. Nausea in warm weather.	Tried both lisinapril and Cozaar, could not tolerate either.	M	57	4 months		7/1/2009 Email
4	moderately high BP	Dry throat and mild cough. Mild issue with erections.	Helped lower my BP and increased my exercise tolerance.	M	45	1 years		6/24/2009
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		1/31/2009
4	hypertension	Anxiety, body aches.	I noticed that my erections are firming now and seem to make my wife happy. My doctor said that there is bye product that comes out of cozaar that makes penis harder.	M	52	20 days		4/24/2008
4	High blood pressure	None	Had what I thought were a lot of side effects which went away after losing 25 lbs of weight	M		90 days		2/9/2009 Email
4	High BP			M	52	6 days		4/12/2008
4	High Blood Pressure	50mg twice a day (am and pm). No noticeable side effects except that which it is designed to do: lower BP.	I'm a non-smoker, and I exercise regularly (treadmill 30 minutes daily), eat wisely and responsibly, and enjoy a single, favorite German beer each evening.	M	60	2 years		1/9/2010
4	high blood pressure	slight chest pains for a while		M	47	2 months		8/11/2002 Email
4	blood pressure	cough at 50mg, moved to 100mg[high rate], one month later, forced to stop cozaar due to severe cough and chest congestion. two days after stopping cozaar,chest cleared and cough almost completely gone.	cozaar always caused a small dry cough.I have been on it for several years, but could not tolerate the high dose.[100mg]	M	66			3/24/2004
4	BP & type II diabetes	No side effects at 25mg per day for one year. When moving to 50mg per day I became so sleepy at work that I dozed off between sentences. I could not stay on the increased dose long enough to determine whether it helped.	Taken in conjunction with 2x4mg Cardura daily.	M	53	1 years		11/3/2004
4	Had bypass surgery	None known	What side effects others had	M	67	4 years		10/11/2004
4	hypertension	Slight cough, especially in the morning upon rising. Unlike. toporol-xl, which killed my libido, cozaar has actually increased it beyond what it was before, which was pretty high. Otherwise I tolerate it very well but I've only been on it for about a month so I suppose only time will tell---so far, so good.		M	54	1 months		9/24/2004
4	Scarring of the Kidneys	bad energy level... feel so tired.. unable to wake up in time for school....	It works and helps my medical condition...	M	19	1 years		12/4/2006
4	Hypertension	Some light coughing. A little dizzy & lightheaded.	I was on beta blocker for nine months. Disaster. During this time I did nothing but sit in a chair and gain weight. Cozaar has been much better. It helps on the blood pressure (just took reading of 115/65), and there is no impact on libido or erectile function.	M	55	4 months		6/17/2007
4	High Blood Pressure	anaphylactic reaction to yellow jacket sting (collapse; responded to orally administered benadryl)	lowered my blood pressure, but not worth the risk for me in the summertime (I had been stung many times previous to taking Cozaar)	M	34	5 years		6/15/2006 Email
4	High blood pressure	Headache	83 and sex 3 times a week? Yeah ...right. Tell us all another fish story. Nonetheless, a great drug, lowers BP well but gave me headaches about a wek later with a 50Mg. per day dose.	M	49	1 years		11/14/2005
4	High Blood Pressure	I feel very tired trhoughout the day. I also feel a little depressed for no reason. I had to take a day off from work becasue I was so tired.	I did have 140/90. It is down to 133/84. It seems to work but, I don't feel right. It is hard to explain.	M	27	3 weeks		1/25/2006 Email
4	High Blood Pressure	Main side effect that bothers me is coughing. Usually just an occasional cough or two but sometimes have what I'd describe as coughing "fits", during which I'll cough to the point of vomiting. Daytime fatigue, nightime insomnia. Sinus/nasal problems.	It IS effective in lowering my blood pressure, but the side effects are bothersome.	M	41	2 years		2/3/2006
4	Intermittent high blood pressure	None really	Better than Ace inhibitors and the cheaper versions of Losartan Potassium as those contain talc and Macrogol which I seem to be sensitive to.	M	57	2 years 50mg 1X D		6/9/2010 Email
4	HBP	DRY, SCRATCHY COUGH (SEE BELOW). I USED METOPROLOL FOR SEVERAL YEARS BUT IT BEGAN TO "SPIKE" IN ITS EFFECT ON BP NUMBERS AND CAUSED ALARMING DIZZINESS. WENT TO LISINOPRIL WHICH WORKED VERY WELL FOR BP BUT CAUSED A CONSTANT/RAGING/VIOLENT/HEAD-ROCKING COUGH. I HAD A CONSTANT SENSATION IN MY THROAT THAT WAS MUCH LIKE ONE GETS WHEN GARGLING CONCENTRATED SALT WATER AND SOME TRICKLES DEEP INTO THROAT. NOT NICE. THE FIRST DAY OFF LISINOPRIL I DID NOT COUGH OVERNIGHT FOR THE FIRST TIME IN MONTHS. (I WAS KEEPING THE NEIGHBORHOOD DOGS AWAKE.) WENT TO COZAAR WHICH IMMEDIATELY REGULATED BP BUT THE COUGH CAME BACK. IT IS NOT AS PERSISTENT OR VIOLENT AS W/LISINOPRIL, AND FROM COMMENTS I'VE READ IN THIS JOURNAL, THERE WOULD SEEM TO BE HOPE THE COUGH WILL EVENTUALLY SUBSIDE, WHICH PREMISE I INTEND TO TEST.	IT WORKS FOR BP CONTROL. HAS CAUSED A COUGH THAT HOPEFULLY WILL SUBSIDE WITH TIME. I HAVE NOT NOTICED (OR ENJOYED) ANY INCREASE IN LIBIDO, BUT WILL GLADLY REPORT ANY SUCH BONANZA UPON ITS ARRIVAL. NO MIND THOUGH; I AM 69 AND MY WIFE IS HAPPY I'M NOT CHASING HER AROUND ANY MORE.	M	69	5 days 100 1X D		2/15/2010
4	high blood pressure	none that i can see so far.the good news is that cozaar just came out in a generic brand,hooray now we can get it for a lower price,the generic name is losartan.		M	48	12 years 50 mgs 1X D		4/18/2010 Email
4	hypertension/diabetes	none		M	43	1.5 years 30 1X D		3/23/2010 Email
3	Post Mild Stroke & HBP	Severe vertigo with nausea & sensitivity to light in the morning after getting out of bed. Some back pain.	When started the med two wks ago, bp dropped & was fairly normal. After severe vertigo, bp rose to 182/109. Planning to discuss all of this with my doctor.	M	56	2 weeks		1/29/2010
3	HP	Had optic migraine(jagged glass vision)3 weeks ago. Had not had migraine for years. Now for the last week my hands tingle but not sure if this is side effect or not. BP has been fine. I have noticed arm muscles sore but I also do kickboxing 3x a week so not sure if that is cause or not. Dr. took me off lisinipril due to cough and losing my voice for 2 weeks.		M	51	3 months 50 mg 1X D		3/2/2010 Email
3	high bp	weight gain despite healthy diet and running 25 miles a week. Low-grade fatigue.	Kept bp around 130/80 with addition of diuretics.	M	55	1 years 25 2X D		7/1/2010
3	Hypertension	Had been taking Lopressor for years, and become habituated. Cozaar gave me fewer side effects than anything else I had tried before - no interference with libido, attention, dizziness, etc. And the positive effect on my BP was immediate. After about two months, though, it seemed to be ineffective. Also, after reading other people's comments, I note that some things I had simply accepted as the difference between Cozaar and Lopressor, or the effects of lower pressure, may have been minor reactions: faster heartbeat, especially at bedtime (I always take at breakfast); a little trouble getting to bed and/or falling asleep; occasional vision blurring.	Glad I tried it, I'll probably wind up pulse-dosing it with lopressor, and as with all drugs YOUR MILEAGE MAY VARY.	M	50	2 months		10/24/2006 Email
3	Not yet			M	49	0 days 30 3X D		4/6/2010
3	hypertension	dizzy spells		M		3 days		10/26/2008
3	HYPERTENSION	RAPID HEART RATE AT TIMES, WHICH CAUSES TROUBLE SLEEPING.HAVE GAINED A FEW LBS.WHEN I FIRST STARTED COZAAR I EXPERIENCED AN UPPER RESPIRATORY INFECTION.	COZAAR HAS LOWERED MY BLOOD PRESSURE SIGNIFICANTLY!	M	52	40 days		3/22/2003 Email
3	Hypertension	Fatigue, dizziness, weight gain and muscle pain but still better than others I have been on. Keeps BP in normal range. I will hopefully have more tired dizzy days than not taking.		M	33	5 years		7/30/2007
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		9/27/2007
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		2/4/2008 Email
3		tired, very irritable,depressed,anxiety,loss of appetite	dont know if these side effects are from the drug or not,i wish i knew,but blood pressure is down from 145/80- 129 /80	M	46	14 months		11/20/2007
3	hbp	none		M	66	10 days		12/7/2007
3	hypertension	dizzyness, light-headedness	worked for first year, but now seeme inneffective	M	63	2 years		12/26/2007
3	Hypertension	Muscle and tendon pain, affecting lower back, elbows and upper arms.	I am asking my doctor for advice on discontinuing the drug.	M		2 years		1/7/2008
3	High Blood Pressure 140/90	Anxiety(don't know what to expect),gas, above average RHR at night and once a day for 3-4 hours I experience a strange fluttering feeling in my chest, but no pain or discomfort	Do these sound normal to the long term users?	M	39	4 days		11/3/2008
3	hbp	lightheadedness & some dizzyness		M	63	2 years		4/7/2008
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		1/7/2008
3	High blood pressure	I have been taking Cozaar 50mg for 5 years now. And at first I did not notice any side effects, my blood pressure was good. But lately in the past year, I have noticed my blood pressure goes up. And then it goes way down, I have been feeling very fatigued, I'm experiencing chest pain, and I get out of breath easily. I don't sleep well at night and I used to fall asleep the moment my head hit the pillow. I get very sensitive, I have a hard time concentrating. I was at my wits end wondering what was going on with me and at least after reading everyone else's symptoms which are like mine, I am relieved I'm not going crazy. I thank all of you for sharing your symptoms.	I know I need to change my eating habits. And as of today that is what I am going to do. I want to somehow get off of this medicine. God has given me wisdom to listen to my body and I don't always do it. But now I am going to take charge of that.	M	59	5 years		11/14/2008
3	moderately high BP	First few days I had a dizzy/lightheaded feeling which went away. I now feel tired/fatigued and a bit depressed. The tired feeling is somewhat less if I take it before bed. The medicine almost acts like a 12 hour sleeping pill.	It lowers blood pressure, but the old benezapril/HCTZ symptoms may actually be worse. I've traded a cough and having to goto the bathroom too frequently with a general feeling of tiredness. I can't say that cozaar is better than the benazipril/HCT it replaced.	M	40	1 months		11/30/2008
3	High BP	Stuffy nose, tired and headache		M	51	1 days		2/11/2009
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		6/30/2008
3	High Blood pressure	After about two weeks on Cozaar 25mg I experienced shortness of breath and difficulty sleeping restfully because of the breathing problem.		M	74	17 days		9/6/2009
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		6/2/2008
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.

2	high bp	extreme joint, tendon pain (knees, calves, shoulders); allergic reaction in the throat -- coughing	taking cozaar and lopressor for five years. i hate them both, but they lower my bp.	M	59	5 years		9/9/2008 Email
2	High BP	Heart flutter, muscle spasms (particularly eye muscle spasms), anxiety, depression, dizziness when standing, insomnia	The side effects are a lot worse when I take the two doses per day that the doctor recommends. When I experience anxiety, I stutter really badly. This does not work well with my job since I work in a call center. I may end up just trying to use fish oil to lower my BP because the side effects of Cozaar are BAD. The only thing that makes them go away is to lower the dose down to half or less, which makes the BP go back up. Its a catch-22. I just need to find something else which can lower my BP and quit relying on drugs.	M	33	15 months		12/9/2009 Email
2	BP	none	I'm taking cozaar, metoprolol and maxide - and my systolic blood pressure still varies from 140 to 107. I don't know what helps, or why it goes that high.	M	78	2 years		5/9/2009
2		ED, unable to achieve an erection sufficient for intercourse. Was fine until I started the Cozaar.	Many people complain about psychological depression while on Losartan Potassium. I was depressed but it was an odd kind of feeling - I would call it agrivated depression. I felt like someone was shouting in my ear all day. Nasty. I'm getting off Cozaar.	M	62	120 days		6/17/2009
2	Hypertension	Light headed & vertigo. Sinus dryness and headaches.	Taking the drug for the first time. Its only been 4 days, so I'll wait and see if side effects subside. The reason I was put on Cozaar was because my hypertension was giving me dizzy spells. I went from feeling dizzy once and awile to feeling vertigo all the time. Not much of a cure so far.	M		4 days		8/31/2009
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		7/7/2008
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		7/13/2008
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			2/4/2009
2	Hypertension	I felt fatigue and anxiety much of the time on Cozaar, but it did bring down my HBP.	I don't trust many of these recent HBP drugs. Sure they are powerful, but at what cost? We are human guinea pigs that are testing the long term effects of these drugs, and we don't know if they are harmful or mutagenic in the long run!	M	45	2 years		1/27/2007
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		10/17/2008
2	High BP	*** This is an update to an early comment!*** *** M 41 2 years 7/31/2008 *** 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.	M 41 2 years 7/31/2008 I went to my doctor and told her of my feelings, after that I have quited the drug and since then life has been much better, and even my HBP is normal!!! amazing, even the doctor is amazed with it :-) I am not training more than before, actually less, but I do eat less salt food and sweets. I don't believe people is writing just for fun or to give the drug a bad name. But for me it worked onle sometimes and after a while i was depressed and all that negative stuff.	M	41			10/25/2008
2	BP	None	Didn;t seem to lower BP ..	M	34	30 days		5/10/2004
2	hi BP	I had some wired coughing and choking sensation 6 month after taking it, my doctor stopped cozzar and put me on some other stuff. After one week, I still have the caught, so not really sure if was caused by cozaar.	I seems pretty harmless	M	43	8 months		1/22/2006 Email
2	High BP	One hour after starting on 50mg Cozaar, I noticed that my hearbeat was irregular. Took about 24 hours to return to normal. Stopped taking and will advise DR. of the side effect. Had heart irregularity and developed bad cough soon after starting on 300mg of Avapro, which is why Cozaar was prescribed. Guess I'll have to try something else.		M	66	1 days		9/25/2006 Email
2	high pp	hyzaar 100 took for 8 months, up from 50, lowered pp to 110 over-60-65 was tired all the time. Hart was fluttering dizzy couldn't sleep. Had to go to hospital thay ran test found out it was damaging my liver. Dr. took me off of it and I felt normal. BB was staying in the 132/83 adv. daily with no med. except htz 20mg. BB has high of 154's/ 87-91 and lowes of 120's/	70's but adv. at end of [taken ramdonly 7 times daily] day adv. as above.	M	63	8 months		3/16/2006
2	Mild hypertension	Dry cough, worse at night, erectile dysfunction not previously present, stuffy nose. I'm going to try to switch back to Atacand.	Was on Atacand, without side effects. Switched to lisinopril when new Medicare drug plan wouldn't allow Atacand. Lisinopril caused dry cough, so physician switched me to Cozaar.	M	77	15 days 50 mg 1X D		6/10/2010
2	hbp / diabetes	Leg pains, and possibly chest pain. I am also taking Metformin, Toprol XL 100mg, Low dose asprin 81mg.	I am taking Cozaar because my Dr. claimed its side affects could help my kidney function, in the treatment of diabetes. So far I haven't seen any results.	M	67	1 years 50mg 1X D		3/15/2010
1	Hypertension	I am in decent physical shape and run about 3 miles 3-4 times per week. But, my blood pressure has been borderline 140/80 for some years. Last year (2009), my pressure stayed at about 150/90ish. I began taking Cozaar and Dr. prescribed 50MG per day. Blood pressure did not change so I was prescribed 100MG per day. Within one week, I began to have numerous dangerous side effects. Chest pain was piecing with pain from upper abdomen through shoulders and back, dizziness, lower back pain, vision bluriness, trouble breathing, and increase of blood pressure to 176/103. Dr. took me off drug immediately and the last event with the drug ended with upper respiratory infection and a follow-on bronchitis bout.	This drug will harm you at the maximum dosage....	M	41	3 months 100 1X D		3/3/2010
1	BP	dizzy, no appetite, head cold, sore throat, miserable		M	49	7 weeks 100 1X D		2/23/2010
1	blood pressure	dizziness, memory, confusion, fast heart beat	I even cut the pill in one half, with much of the same side effects. Very unfortunate, as my doctor said it would help my kidneys, as I am a diabetic. Will now continue to stay on a low salt diet, get plenty of exercise and lose weight. I may return to Norvasc and take potassium if the doctor approves. For me, Cozaar was a true nightmare!!	M	50	7 days 25 1X D		4/2/2010
1	bp	I having chest pain especially in the left pectoris muscle, also shoulder, back, bicep and neck pain. I spent 24 hours in the hospital 3 weeks ago with what I thought was a heart attack. It wasn't, then the dr. thought I may have thrown a PE, no ct w/dye negative for PE, then dr. said it must be pluracy, ok thats it, spent overnight on anti-inflamatories. Still have pain, then I remembered I had the same thing when I was on Micardis, geez, did the lights go on. I am seeing my doctor on tuesday, from there to my cardiologist. I am quiting Cozaar, also on metformin and lopressor. BP running from 120/70 to 100/55. I never had these problems on anenolol.	I feel like I'm having a heart attack all the time, upper chest pain. BP currently 114/62. Nope its the Cozaar. I am done with it.	M	59	1 days 25mg 1X D		5/14/2010 Email
