For High Blood Pressure "Was put on losartan (green pill) back in 2018. Did not control BP, was switched to white pill, 50 mg. Started off with horrible headaches, stopped it for a few weeks and headaches went away. Started back, one night I woke up with HR of 165, had to call 911. 3 trips to ER for terrible GERD, tachycardia, horrible anxiety which I never had before. Insomnia, and horrible feelings of heaviness in head, chest, and legs. Lower legs feel like pins and needles, and numbness. I felt like it was the end of me. Stopped it 8 days ago, I do feel better, only lingering symptoms are dizziness and heavy legs, and just overall tiredness. When will these symptoms go away??? NP and I are monitoring blood pressure, it has been fine hasn't spiked at all since I've stopped losartan. Horrible drug in which the doctors will not believe you when you say the drug causes these things. When will these side effects go away????????????"

For High Blood Pressure "Losartan is a horrible drug. I have been on it with HCTZ for five years. Slowly began to have dizzy spells, mouth sores, leg cramps, dry mouth, chest pains, panic attacks, blurry vision, and extreme fatigue to the point by lunch I would have to leave work and go to bed. My doc checked me for everything and sent me to many specialists and found nothing wrong. I'm throwing this losartan out right now."

For High Blood Pressure "It's a nightmare. I'm only taking 50 mg, and the dizziness and diarrhea won't stop. My doctor said to just cut the pill in half. No way. I will have to figure out natural remedies for BP because this is absolutely unacceptable. Wow. How do things like this get on the market?"

For High Blood Pressure "I've been taking Losartan for less than a month, but I had, and still have, side effects immediately after taking it. I feel dizzy, warmer than usual, thirsty, bloated, tired, have rapid heartbeat with 'thumps', headaches, and have blurry vision. Also, I gained 7 pounds and haven't changed my diet in any way, and I'm active. I'm going back to my doctor next week to see if there's something else I can take instead of this."

Losartan for High Blood Pressure "Male, 53, regular exercise, healthy diet. Started losartan (Cozaar) 2 weeks ago due to high blood pressure. Dropped the blood pressure first day, but still is high - before taking BP was 160's / 110's, now it's 140's / 90's. Noticed frequent urination - like every 15 minutes. I canceled an international vacation because of this. Then came the anxiety at night. Never had anxiety this bad - ever. Finding myself locking the doors, checking to make sure they are locked multiple times. Slight confusion and short-term memory problems. Yesterday bought a $1500 large screen TV that I really did not need and does not even fit on our TV stand. Numbness in one thumb. Dizziness - almost fell backwards off of stool at restaurant. Giving it one more week."

For High Blood Pressure "This drug made me feel so weak and extremely dizzy. My legs felt very heavy also. Sleepy and no motivation. I'm taking 25 mg daily. Was given to me for broken heart syndrome and to prevent stroke because of anxiety/panic disorder. Just have to learn how to deal with stress in a more natural way."

For High Blood Pressure "I was recently diagnosed with mildly high blood pressure 140/90. My doctor prescribed losartan. I usually feel great, walk every day, exercise with weights, garden etc. I took losartan for 3 days, couldn't get off the couch. After the third day, I was so dizzy. Stopped taking it 3 days ago and am still feeling dizzy and confused. I want to feel like my active self again."

For High Blood Pressure "On Losartan 25mg. 38-year-old female, maintaining a healthy diet, no health issues except High BP (hereditary in my family). The medication does lower my BP, but it makes me extremely tired with dizzy spells, unusual muscle cramps in legs/feet, and some numbness in extremities. However, the worst side effect from this poison pill is HORRIBLE damage and loss to my formerly long hair!"

For High Blood Pressure "I have been taking 50mg of losartan for a few years. I never really looked very deeply into losartan past the 'may make you drowsy' stuff on the bottle. As time went on, I noticed that I was getting weaker and weaker to the point that I couldn't do anything. My legs felt heavy and even just mild exertion left me gasping for breath. Getting up, I would feel dizzy. Everything in my body hurt. I have vision and hearing problems in addition to a loud ringing in my ears. I've had a physical, lab work, tests, etc. There is no obvious physical cause for my problems. So, I have started to look into my medication side effects. I looked up losartan and BAM - everything that I was experiencing is listed. I've been off it a couple of days and while it is too soon to tell if that was the cause, I do not feel worse and seem to be on the upswing. Note, I discussed stopping the losartan with my physician first, and I monitor my blood pressure in case it goes back up without the losartan."

For High Blood Pressure "My blood pressure was improved with Losartan, but I had many side effects. My blood pressure would drop to as low as 98 over 84 with a heart rate of 130. I would be dizzy and so tired I just wanted to sleep. At least once a week I would experience diarrhea. I coughed a lot and it was getting worse. I had foot and leg cramps. I was feeling terrible. Since stopping the use of this drug and improving my diet, I am feeling much better, and my symptoms have disappeared. My blood pressure is under control without it. This drug is poison and was killing me."

For High Blood Pressure "I’m a 58-year-old female. The only med I take is 25mg of losartan for over a year now. BP was about 140/95 too often. My side effects are getting worse. Insomnia, headaches, diarrhea, dizzy, tired, feet hurt, have to lay down once a day and no longer have the energy to exercise. I enjoy a couple of glasses of wine a few times a week and try to stay low carb and watch my salt intake. I’m thinking I would be better off not taking this since my quality of life has gone down."

For High Blood Pressure "My husband was put on Losartan 50 mg on Sept. 12. On Sept. 14, he started experiencing brain fog and an ache in his right shoulder, along with sleepless nights. The symptoms progressed to unsteadiness on his feet, uselessness of his right arm, and tremors. I called the doctor, and she cut him back to 25 mg on 9/23. Still, the symptoms progressed to so much brain fog that he doesn't know how to use the remote control, can't find things that are right in front of him, and has given up driving and cooking. I have to cut up his food. We went to the ER this past Saturday to rule out a stroke. They said it is his medication. Back to the doctor, she took him off Losartan after he begged her. She upped his water pill and kept him on his Amlodipine to see how he does. He was up all night last night, missing another day of work today. I am sure I have missed something that this medicine has caused him. I pray there are not long-term effects. I don't understand why, if it is also recalled, the FDA has not pulled it."

Losartan for High Blood Pressure "I have had high blood pressure for years and have just started a medicine routine. I tried Zestril and had great results but did not like the cough. So, my doctor switched me to Cozaar. This makes me cough, makes me tired, dizzy, and constipated."

For High Blood Pressure "The meds do not work! I have lost over 25 lbs, and cholesterol and glucose levels dropped. I engage in both low and high impact workouts 5 days a week, and this medication has done nothing to lower my blood pressure, in fact, it has increased it! I went from a low dose (25 mg) to 50 mg over a 2-month test period, and the blood pressure was status quo, with terrible side effects including dizziness, nausea, shortness of breath, and migraines."

Losartan for High Blood Pressure "I have been taking generic Cozaar for about 3 months. Taking 25mg once a day along with 12.5 mg of Hydrochlorothiazide. It mildly lowers my BP. I get readings near 120/80, but also get high readings sometimes as well. The doctor wants to up the dosage to 50mg per day. I want to wait a while as my blood pressure isn't that bad yet, and I am trying to slowly adjust to the side effects. I am constantly 'dry' and thirsty for water. I have bad dizziness that gets really bad on occasion. The side effects are much less for me than Lisinopril, which had me coughing 24/7 and gave me bad angioedema after 3 months."

For High Blood Pressure "My cardiologist added this drug to my other medications I have been on and taking with no problems. Not even two days into taking Losartan, I am experiencing side effects. I noticed I could not taste my oatmeal this morning, a terrible whole-body feeling of being so ill, stomach pains, sweating in my feet, blurred vision, not wanting to eat, wanting to throw up even after a sip of water, and feeling tired, dizzy, and buzzing in my ears, to name a few... and this is ONLY after two days of taking this medication. I called my doctor and told them I do not want to and will NOT take this medication anymore. I am waiting for them to call me back right now... I've had enough of these so-called drugs that make me feel so absolutely horrible."

Losartan for High Blood Pressure "I've been taking this medication for about 1 1/2 months or a bit longer. I have been having a lot of bowel movements, stomach discomfort, went from weighing 123 lbs to 98 lbs, not to mention feeling dizzy and fatigued. I just left a message with my doctor's reception desk, and I'm hoping I get a call back today with a reply to my message."

For High Blood Pressure "I have been very healthy my entire life, thank God, until last year when my blood pressure started going up. The doctor prescribed Metoprolol and Lisinopril. I started coughing constantly, which led me to the ER, thinking I had pneumonia. The ER doctor switched Lisinopril for Losartan Potassium. The leg and back pain are unbearable to the point that I can almost not stand or walk. I am afraid of falling, feeling dizzy and tired. I don't need to live with this quality of life. The dangerous side effects are even worse than what I felt when my blood pressure started rising. There has to be something better than this."

For High Blood Pressure "After trial and error getting me on the right BP meds, I am now on losartan. I have been on it for 3 weeks now and am fairing pretty well on it. I have had a bit of dizziness and a little breathlessness, but nothing to worry about. I had a headache for the first week, but that went as quick as it came. So far, so good for me, bringing BP down nicely although it wasn't too high to start. I am on 25 mg. I am happy to have found something that agrees with me."

For High Blood Pressure "While it lowered my blood pressure, I had huge dips in BP, which left me exhausted and dizzy. After a year on this medication, I had severe muscle cramps, horrible stabbing headaches, stiff muscles, severe heartburn, and weight gain. I told my doctor about this, and he just shrugged. I had trouble breathing on Lisinopril (my throat just closed up), which I took prior to this. I stopped taking the medication and began taking magnesium and calcium, and my BP is not rising, but my symptoms are all gone. Go figure..."

For High Blood Pressure "I was taking losartan 25 for 6 years. I didn't experience any side effects. But 3 months back, when I checked my BP, it was 160/110. Dr. advised me to take losartan 50. Since I started taking losartan, I noticed that I get dizziness while standing after sitting for a long time and difficulty in passing urine. Now I am going to consult my GP and ask him to give some other medicine that has fewer side effects or to go for natural treatment without any medicine. May God help all of us from the side effects of medicines."

For High Blood Pressure "Given this generic medication for hypertension. My B/P was good during the day. I am 59. I have been on it for 7 days now, and since starting it, my heart sometimes feels like it has a 'thump' in the middle of my chest. Without fail, my B/P goes up at night around 10-11 pm, and I find it very hard to sleep for being afraid I will have a heart attack during the night. I take losartan 25 mg pill around 8 pm. I wake up around 1 am with my B/P up to 150-160/90-95 and my heart pounding! I was once on Benicar and was terribly dizzy every single day. I don't know if I will be able to continue losartan, but I'm more fearful of the other BP meds like beta blockers! Very scared!"

For High Blood Pressure "I take 100 mg. My blood pressure is still not consistent. But one thing I am sure of is that I'm dizzy all of the time. In addition to several other side effects that I am expecting, fatigue is definitely a problem, as well as back pain. At first, I thought it was directly related to my back surgery 6 years ago. But I'm seeing now that it is listed as a side effect. But what is terrifying for me is the blurry vision. All of the side effects are affecting my quality of life."

For High Blood Pressure "This is the first blood pressure medication I have been on, and after one month, my experience has been terrible. I'm glad I found this site, as others have experienced serious problems like mine, which only added to my anxiety. I feel stuck in this circle where anxiety causes chest pain, and chest pain causes anxiety - it's just terrible! My biggest issue has been tightness in my left chest, which radiates throughout my shoulder and back. The only relief I can get from it is 800 mg ibuprofen. I also experience extreme vertigo at times, blurred vision, anxiety, and sleeplessness. I feel like my chest is bigger, which could be the pleural effusion I read about here. It's frustrating that drugs come with so many side effects. Statins also caused me trouble with unexplained pain. I won't be taking this drug anymore. I'm scheduled for a stress test tomorrow, but I'm canceling until I can get this medication out of my system."

For High Blood Pressure "I've been on Losartan for 2.5 years. I haven't had an issue with it until the past 4-6 months. I've been experiencing dizziness, headaches, general nausea, and malaise... and a significant amount of hair loss. I've been checking my blood pressure multiple times daily for the past week, and all BP readings have been higher than before I was placed on BP meds. When my diastolic is above 100 mmHg is when I become symptomatic - dizziness, nausea, headache, heart pounding... etc. I have been thinking these symptoms could be thyroid-related... however, now after reading others' posts, I'm wondering if it's not the Losartan. The high BP on meds has been quite concerning. The hair loss has been depressing... but manageable. Contacting the doctor on Monday."
