| 3 | Bp | Been having anxiety and dizzyhead, the head congestion | M | 38 | 3 years 100mg | 6/11/2017 | 1 | High Blood Pressure | I was on 50mg for years with no problems. BP getting a bit higher so doc put me on 100mg. I have never felt so ill. Depressed, tingling, tremors, electric shock, weight loss. Went back to 50mg and after 9 days feel a lot better. | M | 52 | 5 weeks 100mg 1X D | 5/8/2017 | 2 | High blood pressure | Too many to list | Not really working for me | M | 58 | 2 months 25 | 3/5/2017 | 1 | High Blood Pressure | Strange flu type feeling with incredibly bad mood all the time. | My doctor acted like he didnt believe me but this stuff was horrific. I felt like I had the flu all the time and it would never go away until I stopped taking it. I switched to Clonidine and finally got a bp medication that I can handle the side effects. | M | 38 | 3 months 100MG | 3/4/2017 | 1 | Hbp | Back and shoulder pain also had trouble urinating, so I stopped taking the drug. | F | 67 | 3 months 100 mg | 1/30/2017 | 1 | Hbp | Back and shoulder pain also had trouble urinating, so I stopped taking the drug. | F | 67 | 3 months 100 mg | 1/30/2017 | 1 | HBP | I have high blood pressure and depression. Have dealt with depression most of my life. Take an ssri for depression. When blood pressure meds were added 10 years ago ssri didn't seem to work as well. Eventually adjusted some to 50 mg losartan/Htc. I still didn't feel as well mood wise as when I wasn't taking HBP meds. Also take a calcium channel blocker. Whenever the heart doctors have increased Losartan to 100 mg depression gets much worse as does agitation and bad dreams, restless sleep. I lose interest in everything I normally enjoy and have no motivation. I also reacted the same way on Diovan and Benicar when doses went higher. It does help with HBP but I cannot tolerate a higher dose. | If you suffer from a mood disorder be very careful of the dosage and combinations of HBP meds. | M | 61 | 10 years 50 mg 1X D | 1/13/2017 | 1 | HTN | Food is disgusting, can't take the drug any more Been off 3 days and food still bitter. | F | 60 | 3 days 1X D | 10/7/2016 | 1 | High Blood Pressure | Couldn't breathe through my nose AT ALL, headaches, violent mood swings (I acted like a psychopath at times), kidney damage. | Barely lowered my blood pressure. | M | 39 | 3 years 100 mg 1X D | 6/23/2016 | 1 | Hbp | Anxiety/panicky feelings | Really don't like taking any drug/too many side effects | F | 67 | 8 months 100 mg | 6/6/2016 | 1 | High blood pressure | Heart racing leg pains like cramps | Chest stomach cramps | F | 66 | 1 months 100 | 5/13/2016 | 1 | Blood Pressure | Blindness | After I had taken one pill about mid-afternoon, I awoke about 3:00 in the morning very dizzy, the room was spinning. I could not see out of my left eye the next day. I had developed a retinal artery occlusion in my left eye. It's irrevocable. Drugs.com and FDA list blindness as a common side effect of Losartan. Why don't doctors know this? | F | 79 | 1 years 100 mg 1X D | 5/5/2016 | 1 | Hypertension | Dry mouth muscle cramps espescially in legs fogginess tired | I have been on this drug in different doses for 3 years. Beside all the side effects it doesn't do a good job of lowering blood pressure I will be trying a different drug | F | 63 | 3 years 100 1X D | 3/1/2016 | 1 | Hypertension | Dizziness, vertigo, pounding headache, spaced out, lethargy, sleep disturbance, frequent stools and urination | Side effects started within a few hours of 1st dose. Headache and vertigo was so severe I called doctor after 7 days and was instructed to stop tablets immediately | F | 65 | 7 days 50mg 1X D | 2/19/2016 | 1 | High Blood Pressure | M | 43 | 10 months 50 1X D | 2/17/2016 History | 1 | Hypertension | Swollen ankles tingling and burning legs and feet | Side effects cause sleepless nights | F | 73 | 1 months 25mg | 1/23/2016 | 3 | high blood pressure | Pain in my joints after taking cozaar 6 weeks. Hip lower back and shoulder pain very painful.My doc says i have to get use to some side effects. I'm not so sure I can. | Almost the same results i got when i took an ace inhibitor although the Cozaar is not quite as bad. | F | 83 | 6 weeks 25 ms | 1/22/2016 | 1 | Blood pressure | Chest pain, indigestion, asthma like symptoms, fatigue | Did lower BP. Could not tolerate side effects. | F | 67 | 4 weeks 50 mg | 1/18/2016 | 3 | hbp | Not really but it's not helping my BP and also my 2months old baby is reacting to it... Having air bubbles in the stomach | With the BP think it will help in the long run since I started not quite long.... Few days | F | 36 | 6 days 50 | 12/30/2015 | 4 | Blood pressure | Weight gain, body aches, exhausted, sleep problems,indigestion | F | 49 | 1 years 50 | 11/8/2015 | 1 | Hypertension | Swelling calves and tingling legs and feet | Sleepless nights with side effects | F | 73 | 7 days 25mg | 11/8/2015 | 2 | Blood Pressure | Since being on this medication, I have been having anxiety attacks, mostly at night but sometimes during the day. It has lowered my BP but not sure how much of this anxiety I can take. I've never dealt with this before. Also having some issues with short term memory and fuzziness. Makes it harder to do my job. | F | 47 | 9 months 50 mg 1X D | 9/23/2015 | 2 | Hypertension | When doctor incresed me from 25 to 50 mg after 2 weeks and no results, I did not see any significant side effects. Now for the past 2 days he has increased me to 100 mg. I have no improvement in my bp. Runs 120's to 140's systolic and 90's diastolic. Since the increase to 100mg, I seem to ache all over. I do feel like I can get a deeper breath, but the aches are terrible. | F | 52 | 4 weeks 100MG 1X D | 9/10/2015 | 1 | high blood pressure | Extreme tiredness,very weak,fever,light headed constantly urinating I can barely stand,joints ache shortness of breath,to some it up this is not for me,I stopped taking it two days I felt better that's how I know it's the medicine.. | bad medicine | F | 32 | 3 weeks 25mg | 8/19/2015 | 1 | Bp | Anxiety,chest pain, vision problems | well my Fifth BP medicine and my last, I just decided this poison is not for me. I have had the worst 3 weeks on this stuff. I'm going the Holistic route. So other people have done it so can I, my Bp is 160/90 this medication makes it rise. I will return to meds if I can't achieve my BP goal by holistic means in a year. Diet and weight loss are the key. People who say that they have no side effects from this drug don't know their body IMHO. Your body wants to be healthy, this stuff is just a bandaid for your health problem. You can cure yourself and be better for it👍🏼 | M | 60 | 6 weeks 50 | 8/13/2015 | 2 | HYpertension | Fatigue, weight gain, itchy rash, makes me want to sleep all day. | Doesn't really decrease bp | F | 62 | 1 days 50/12 | 7/1/2015 | 3 | High blood pressure | Tiny cough that lasted a week. | No really bad side effects. Mild cough. | F | 50 | 3 days 50mg 1X D | 6/28/2015 | 1 | High BP | Heavy blood in stool and urine, swollen & stinging, burning in my eyes, blurred vision, loss of concentration, dizzy, back & side pain, confusion, entire body swollen, headaches, lethargic, itching, bug like feelings, too low blood pressure. It felt like I was poisoned. | When will these feelings go away after I stopped. 2 days off now. I told the Dr. about the bleeding and very low BP & she said to take it at night instead of the morning. My cardiologist said to stop it completely. | F | 62 | 5 days 50 | 6/7/2015 | 4 | hypertension | Used cozaar 15+ yrs, good control, no bad effects. Then Bam! Drs. Want to take me off of it. Had recent high potassium levels. First thing they want to do is TRY everything. I am skeptical to say the least. | F | 68 | 1 days 100 | 2/25/2015 | 2 | Hypertension | Within 3 days experienced significant muscle soreness after exercise. This was new to me. Fatigue and continued muscle aches and joint pains. Seem more depressed and very fatigued. Stopped taking it and after a week the aches and pains are 50% better and mood and energy returning. | This worked very well for my mild hypertension, but cannot tolerate the side effects | F | 52 | 90 days 50 mg 1X D | 2/11/2015 | 3 | High Blood Pressure | Malaise, possibly depression, down, low energy. Might be from varicocele, but also strange pain in tip of penis. Abdominal ache on lower left side, sometimes headache. | I've been on this for three weeks, after having a horrible experience with Lisinopril. I had been taking Lisinopril for a year at 7.5mg/day, but two months ago, my doctor said up it to 10mg. Within three days, I had horrible jitters and muscle aches, and was super down, debilitated, painful urination (was tested for everything, everything negative, and normal). I requested to be switched to losartan. Felt awesome for the ten days after lisinopril. Jitters faded. Felt good. But at about 12 days on losartan, and I started feeling varicocele pain, low energy, depression, abdominal pain, and a weird burning when urinating. I cut pills to half for a couple days and felt a little better. I just can't tell if these are side effects, or part of my varicocele pain. Keeps BP in control, but last only exactly 24 hours in my system. It's been a rough few months. The best thing about losartan is the ability to achieve an erection with no problem. I had problems on lisinopril, and didn't realize how bad it was until I got on losartan, and it's better quality than it ever was with viagra - and it's all me. That in itself makes me want to push on and try to overcome any possible side effects. | M | 47 | 21 days 25mg 1X D | 2/5/2015 | 1 | hypertension | Headache, chronic, occasional dizziness | F | 62 | 25 mg 1X D | 1/19/2015 | 1 | High Blood Pressure | Chest tightness. Extreme coughing. Electrical charges on feed and hands. Itching. Arrhythmia a couple hours after taking it...lasted for only a couple of hours. | Losartan never brought my blood pressure down. Doctor didn't know the side effects of this drug....had to educate him about it. Doc did an EKG on me....said I was having a heart attack. Went to hospital. Their EKG and blood work didn't show heart attack. Doctor in ER said Losartan causing cough and chest pain. Requested from my doctor to take me off Losartan. Increased my Bystolic to 10mg. BP came down. | M | 62 | 3 months 100 Mg 1X D | 1/8/2015 | 1 | high blood pressure | Depression, confusion, and anxiety. | I was wondering why I felt depressed, confused, and experiencing anxiety/panic attacks. I began reading the side effects and noticed those are some of the most common effects. I want to stop but Physician advice me to try half of the pill and monitor my BP and side effects. | F | 41 | 9 months 50 mg | 11/26/2014 | 5 | High Blood Pressure | No side effects. | Has controlled my BP and I have more energy than before. Also seems to be calming. | M | 62 | 4 months 100 MG 1X D | 11/17/2014 | 1 | high blood pressure | Light-headed, fast heart rate, ears ringing. Not lowering my blood pressure at all. | Nifedipine XL 60 mg and lisinopril 40 mg had been controlling my blood pressure well. The doctor changed me from lisinopril to losartan because of the annoying cough caused by lisinopril. Now my diastolic has shot up to the mid 90's, heart rate over 100, and my head and neck feel full of pressure. I'd rather put up with the lisinopril cough than have a stroke. Useless medicine in my case. | F | 64 | 3 days 100 mg | 11/14/2014 | 4 | high BP | tired, fatigue, light-headed | appears to do the job, but the fatigue is distressing. | M | 60 | 2 months 25 1X D | 10/14/2014 | 2 | HBP | I have had an increase in BP while on 50 mg and Dr increased to 100. Now, ankles and legs oedematous and skin feels tight. I see Dr. Next week and going to ask to go off of this med. I have never had problem with Linsinopril except for the nagging cough which I would gladly trade for this uncomfortable edema and chest uneasiness which I never had before. | I do not care for this med. I feel worse on it than I did before when on Prinizide. | F | 59 | 1 months 100 1X D | 8/18/2014 | 1 | blood pressure | Severe vertigo every time I laid down. Quit taking it and went to doctor. He said the vertigo was just a coincident and not the med. He said to start taking 1/2 pill once the vertigo quit. I knew I shouldn't take it again, but I did when the vertigo stopped after 2 weeks. 2 days after I started again I had vertigo that lasted even longer - about 6 weeks. I also developed labyrinth that lasted for months and I still get it on and off. I'm still scared to lay flat down and sleep elevated a year later. | Would NEVER take this medication again | F | 44 | 3 days 50 1X D | 7/28/2014 | 3 | HBP | No side effects, but hasn't lowered my BP (maybe even increased it slightly??). Dr. wants to put me on Diovan, but am thinking I should just go back to cutting out sugar and refined carbs and control it the natural way :/ | F | 59 | 3 months 50 mg | 6/20/2014 | 5 | Blood Pressure | None | DR, switched me from Diovan to Losartan for cost reasons. An earlier rating mentioned this helped with ED. I found this to be true, too. Am taking Cialis 5mg. daily for BPH and ED. | M | 55 | 60 days 100mg 1X D | 6/12/2014 | 1 | High blood pressure | Bp stayed high. After about 1 month or so chest would hurt continued taking. Told doctors they didn't change it one doctor even said I heard something when listening to heart did nothing two weeks later heart went afib. Went to er after one day got it back in gave me more medicince and left me on this one also. Tried to tell them my heart still hurt after I took it. Went to another doctor he took me off and heart stopped hurting. No more afib. Been two years. | F | 58 | 3 months 30 | 5/8/2014 | 1 | hypertension | The generic version does not work. If anything BP increased. | F | 51 | 3 years 50 mg 1X D | 4/12/2014 | 1 | High Blood Pressure | I tried taking this medication about 2 weeks ago and got really bad chest pains for 2 days. Being an EMT I stopped taking it because my pain was bad. I tried taking it again today thinking maybe something didn't react well with it but same thing. I took it this morning and about 4 hours later my chest pain is back. I'll be calling my doctor to say I can't takethis medication. | F | 43 | 3 days 40mg daily 1X D | 3/9/2014 | 1 | High Blood Pressure | AFTER BEING ON DIOVAN HCT FOR 10 YEARS WHICH CONTROLLED MY BP VERY WELL WITH NO SIDE EFFECTS AT ALL....INSURANCE REASONS SWITHCED TO LOSARTAN...INSTANTLY HAD HORRIBLE HEADACHES AND AFTER 2 WEEKS BP WAS CLIMBING UP...155/105 AND CONSISTENT BAD READINGS...SUCH A BAD MED I DECIDED ID RATHER PAY THE 400$ A MONTH JUST TO BE BACK ON THE DIOVAN....AFTER SWITCHING BACK MY READINGS WERE INSTANTLY BETTER, AND IM VERY HAPPY . | F | 27 | 30 days 50 1X D | 3/9/2014 | 1 | Hypertension | Dizzyness, fast heart rate, insomnia, tiredness, weakness in my arms and legs, bresthlesness, the worsf was the burning sensation in my throat and esophagus, erratic emotions. It was like I was wide awake but tired and bresthless. I tried to run and thoughgt I was going to die. This is not the medication for me. | F | 35 | 3 days 25mg | 2/22/2014 | 2 | high blood pressure | Body feels HUGE. Restless legs pain in knees and lower legs. Started on 100mg got a rash, severe itching, hair loss, no energy. Dr cut it back to 50mg and no improvement getting worse. Used to work out 3-5 times a week. Now lucky if I can stay in the elliptical for 15 minutes. If I skip this medication for a day, I don't feel as swollen until about 5 or 6 hours after I take it again. Insurance will no longer cover divan but I am not staying on this. | F | 60 | 7 months 50 mg | 1/27/2014 | 3 | High Blood Pressure | awful insomnia & muscle aches | believe it or not, helps with ED issues | M | 64 | 30 days 25 MG 1X D | 1/14/2014 | 2 | blood presssure | constant headache and upset stomach terribl meds took 2 years to realize this.....went to many doctors..... | F | 65 | 1 years 100 mg 1X D | 1/12/2014 | 1 | high bliod pressure | Hair loss.severe panic attacks.big Johnson stopped working.this crap sends me to the Er. | M | 54 | 2 months 75 | 1/5/2014 | 3 | hypertension | Bloating, gas, phlegm unable to cough up since on ramipril, weight gain that will not go away with exercise, sore on tongue | I'm going to go off of Cozaar for awhile to see if can shake this phlegm from Altace. and shake some of this weight off. | M | 64 | 30 days 50 mg x 1 1X D | 11/11/2013 | 2 | lower blood pressure | Swelling in feet and legs, retaining fluid.

Acid reflux Severe.Scalp Itch.. | I've used cozaar/ potassium losartan for about 2 yrs. Had constant side effects..Cozaar really made me ill. I informed the Doctors but all dismissed the side effects. Eventually12/09/2013 admitted into hospital for Gastroscopy endoscopy. Had six biopsy's now got Barrett's oesophagus due to constant burning of throat,also erosive gastritis caused by acid formed from Cozaar. I took myself off Cozaar for 3weeks now and feel so much better.Why don't the Doctors listen when patients complain about side effects it could save unnecessary anguish and pain. | F | 72 | 2 years 50mg 1X D | 9/13/2013 | 4 | Hypertension | Pain in shoulders and calves | M | 74 | 160 days 50mg 1X D | 8/19/2013 | 1 | Hypertension | Worst drug ever! Short of breath, rapid heart rate... These two side effects are worsened when i try to take any type of medication--whether RX or OTC. And I have been off this horrible drug for four months--I pray it will go away.... | F | 57 | 2 months 25 mg | 7/26/2013 | 4 | High blood pressure | Slight depression. | 50 mg once daily lowered blood pressure. After several years, BP increased. Doubling the dose to 100 mg did not make any improvement over 50 mg -- had to add a second medication (HCTZ). Improved libido. | M | 65 | 10 years 50 mg 1X D | 7/24/2013 | 4 | ^ Bp | 3 days no problems as of yet....bp up and down but 1 good ready 124/76 I haven't seen that lately. I'm a herbal person so this is all new to me taking prescribe meds on a daily basis...and your reviews are scary.....I'm recording my bp and what I was doing @ the time and date. Give to my doctor so he can see bp pattern and eat a balance healthy diet...exercise...and pray to control bp and get off of meds totally. | 49 | 1 days 25 | 6/22/2013 | 1 | Hypertension | Low back pain, Increased urination, hypoglycemia, cramps, anxiety and depression. | Beware, the side effects of this medication will sneak up on you. I started at 25mg once a day and went up to 50mg a week ago. At first i tolerated this med well. Then I started experiencing problems with my digestive system (cramps, nausea, lack of appetite.) Then I developed a pain in my right low back in the location of my kidney. When I went up to 50 mg, I started experiencing rapid heartbeat after the second dose. Last night, my heart was beating so rapidly I was afraid I was going to have a stroke, so I had to lay in bed and take deep breaths until my heartbeat seemed to slow down and I eventually went to sleep. As I write this I am resting and discontinuing this nasty medication. Earlier in the day, I was out shopping when I suddenly became pale white and felt like I was going to faint. As I have experienced hypoglycemic symptoms in the past (but under control for many years) the only thing I could think of to do was ingest sugar immediately. Surprise, the symptoms gradually alleviated and I made it home (just barely.) I am continuing to take glucose tabs but am feeling better. Be VERY careful with this med and don't drive until you know how it will affect you. | M | 52 | 14 days 25 2X D | 5/18/2013 | 4 | hypertension | Possible vivid nightmares. Hard to discern if this medicine is the cause. | Tried metoprolol, lisinopril, HCTZ, and diltiazem before trying this one and having no gi side effects. Worked for me versus the others. | F | 50 | 6 months 50 mg 1X D | 5/17/2013 | 1 | Hypertension | Tachycardia (rapid pulse) 135 bpm requiring hospitalisation, hot sweats, flushing, skin rash, anxiety, panic attacks, irritability and insomnia. | BP did not lower while taking Cozaar, it increased. Changed to Losartan (ARB) because ACE did not suit me and found it even worse. | M | 31 | 28 days 50mg 1X D | 5/12/2013 |
