For High Blood Pressure "I started on losartan 50mg daily, bp went down at first, then became higher, so increased to 50mg bid, worked with bp decreasing for a while then bp increased so my losartan to 100mg daily, again bp decreased, next it was staying up, wanted to change the bp meds, instead 100mg bid. I started with insomnia, bp at 130s/80s, now it is up to 226/122 yesterday. and this is the highest, 190s/100 average now. My legs hurt and it's hard to walk or stand for more than 15 min. Have leg cramps at night more often, headaches every night, nauseated since I started the losartan, now I vomit occasionally. Intense back pain between my shoulders, my right side here my liver hurts every day now, I'm tired all the time, brain fog is worse, I go see my doctor this month. I get dizzy occasionally. At least I lost 30 lbs, the upside. I'm decreasing the bp meds on my own to see if I feel better. My lower back is in pain daily. I haven't gained any weight, but my abdomen is getting larger."

For High Blood Pressure "This was the fourth BP medication I tried. I've been on Lotrel, Lisinopril, Atenolol, and last Losartan. I've tolerated Losartan the best. Started at 25 mgs and immediately noticed pain in feet, difficulty sleeping, inconsistent sleeping, head pressure, and dizziness. Cut the pill in half and requested a decrease from my doctor. Started on half a pill, 12.5 mg of Losartan and 15 mg of HCL. Foot pain dissipated, but insomnia remained. Started taking sleep aids, so another pill to counter the effects. Also noticed headache was persistent and so was dizziness. Will look to try something else."

For High Blood Pressure "Losartan is very effective at controlling my BP to a typical measurement of 120/75. When I initially started taking losartan ~10 years ago, I took it in the morning and experienced lightheadedness/dizziness. My doctor suggested taking it at bedtime, this strategy worked great and allowed my body to adapt. After a short amount of time, I changed to taking it every morning and had no problem with lightheadedness/dizziness. I appreciate what this medicine has done to regulate my blood pressure."

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 "Doc switched me from lisinopril to losartan because I had a cough. Been on this for two weeks and from day 1 had weak legs, a heavy feeling in my head, confusion, and insomnia. By the second week, started having heart palpitations, dizziness, and tingling in my right foot. The last straw was red, itchy eyes and a swollen/sore throat. Stopping this tonight. Rather take lisinopril and deal with the cough until I see my new doctor on Friday. Think it also makes me tired, constipated, nauseous, and without appetite. Did not look at side effects first, but when I listed how I was feeling since taking this drug, they were right there. I'll keep looking for something better, but am also following the DASH diet and have lost 30 lbs recently, so hope to be off this drug soon."

For High Blood Pressure "Took some time getting used to a low dose of 25 mg, but I thought it deserved a chance since other meds were a disaster for me. In the beginning, sharp muscle spasms in my back, which eventually subsided. Started getting bad dizzy spells, one of which forced me to pull over while driving. Not good. Dr. said discontinue. Now it’s just diet and exercise. BP normal. 109/67 last night."

For High Blood Pressure "This medication is terrible. I have been running a low-grade fever and have had dizzy spells and ended up in the ER with a BP spike and chest pains. Now at 39, I have to have a stress test done. I have only been taking this for 5 days, and last night, after my ER visit, I took my clonidine, and my BP has been fine all day... never again will I take this medicine."

For High Blood Pressure "I am 40 years old. My blood pressure was very high, from 149-204, scary high. My doctor put me on Losartan 100 mg once a day. The first week, I was a little dizzy and sleepy. I'm fine now. After the first week, no side effects. It says don't drink on it, but I do, and I'm fine :) I drink wine, beer, etc."

For High Blood Pressure "Started with 25 mg daily about 2 weeks ago. Only side effect is in the morning when I'm trying to wake up, I'm so dizzy that I can't open my eyes. The room is spinning so bad. After about 5 minutes or so, I can slowly get up, but I stay dizzy for a few hours after that. The spinning is pretty severe, not sure what to do. Anyone else have this side effect?"

For High Blood Pressure "Losartan has been very effective controlling my BP. Started at 100 mg, which made me extremely tired and lethargic. I cut back to 75 mg (1 50 mg/ 1 25 mg). I am experiencing intermittent dry cough and extremely dry mouth during the night. After 4 years, I am beginning to experience some of the other documented side effects like dizziness and stiff/sore muscles. However, I have had fewer side effects with Losartan than other BP meds. (I am 69 with an enlarged aorta)"

For High Blood Pressure "I was removed from Valsartan after the recall. I had been on Valsartan for over 15 years. I am currently adjusting to Losartan 50 mg. The past 3 weeks have been upsetting. I am very glad that I read some reviews by others. I hope that my comment will ease someone else's mind. The effects have been... horrible dizziness and lightheadedness... anxiety presented as fluttering heart and shakiness. I did not put it together right away, but I am convinced it is my body adjusting to new/different chemicals."

For High Blood Pressure "On 100 mg. My BP was around 147/95 for several years. The odd thing is I'm fairly fit. I got off big cardio a few years back and just lifted weights 5-6 days a week. Yeah, I got big, but I knew things were not right, BP was HIGH. Got onto Losartan. The first few days on 100 mg, I almost passed out, sweated profusely, was dizzy, and really shouldn't have been driving. I've switched it up to 50 mg morning and 50 mg night. Now my BP is back up high, and I'm just not seeing results (I'm back on 30 minutes cardio, 30 minutes weights daily, sometimes double that). The first month this Losartan really messed me up, couldn't concentrate, personality kind of disappeared for a while. Back level now, but if I get even a little bit dehydrated, I feel faint."

For High Blood Pressure "I have been on this for 15 years following a triple bypass op. Until recently, I did not connect my problems with this drug. Now, all the constant need to urinate, the hip pain, the runny nose, the dizziness, the shakes, the tinnitus, the itchy skin, the dry mouth all fall into place. I am expecting my annual heart check-up this month, I stopped taking Losartan recently in order to test my symptoms before the appointment."

For High Blood Pressure "Started out okay on this after switching from Lisinopril, which controlled BP to 120/80. Then started getting excruciating bad spasms, which I attribute to this. Then came the sudden dizzy spells. Blacked out behind the wheel and got in a car accident last month. Fortunately, I was not injured and only minimal damage to my car. This stuff is scary, but seems to control BP reasonably well."

For High Blood Pressure "Brutal medicine, this is the third and worse by far I've tried. Side effects I hit are exhaustion, can't stay awake past 9 pm, and dizziness in the morning. Major pain and tightness in my knees to a point it affected my walking. Took me 10-15 minutes to get out of bed in the morning. It took 2-3 weeks of taking losartan to start feeling it, so it can be deceiving. I'll take the HBP over the pain."

For High Blood Pressure "I started with a water pill for HBP/hypertension, but it wasn't working like my doc wanted it to, so she prescribed me LOSARTAN on June 21, 2018. I started taking it on July 2nd. I have had a migraine every day this week. I've been a migraine sufferer since I was 7. Before losartan, my migraines hit hard only around my cycle time but not every day. I also have seen a shift in my mood, tiredness, extreme dizziness, and brain fog/confusion. I was trying to figure out what was going on with me, then I googled the side effects of this drug, and BAM, there it is! I will not be continuing this medication and will definitely be talking to my doctor about switching to something else."

For High Blood Pressure "I started taking Losartan 50, it's almost two months now. I started feeling so nervous for no apparent reason, to the extent that even when my phone rings, my heart pounds. I have severe dizziness, I feel so low every day, I am scared to go to bed, everything scares me... I AM SCARED OF DEATH. All these have started now. I went to see the doctor because I thought I was suffering from anxiety due to something else, but when I told him I am on Losartan, he said, oh YES, that's the culprit and changed it. Today is day 2 on a new drug, and I just can't wait to feel okay again. This is a bad experience, especially the anxiety attacks, it's bad news."

For High Blood Pressure "Foggy, blurred vision, vertigo, itchy skin, muscle aches, swollen ankles with kidney pain when on 50 mg four times daily. Much better when switched to 25 mg twice daily. Bad hives with Solco Labs, 25 mg bid. Off now. The unfortunate issue is when you have to change pharmacies due to insurances you have and the labs that make the drug aren't available at the new pharmacy. Different issues can pop up due to ingredient differences and different makers. This is what I have had to work with, as well as adjusting dosage to alleviate side effects."

For High Blood Pressure "I recently took Losartan for 10 days. Within an hour of taking the first dose, I had a huge dizzy spell, became very nauseous and shaky, and my balance was way off. I drove straight home, barely able to walk. I stayed on the drug for 10 days because I was told 'you have to get used to it.' I didn't leave my house for the 10 days because it was too dangerous with those symptoms. I normally exercise and walk daily and have part-time jobs. Couldn't go to anything. After 1 day of stopping it, I am getting better, slowly."

For High Blood Pressure "47-year-old overweight male, need I say more. Dr. put me on 25 mg of losartan because of a 120/88 reading at annual physical. Did no research so I wouldn't predispose myself to side effects. From day 1, they were intense 6-8 hours after taking the pill. Leaving work on day 1, I was convinced I was having a stroke or a heart attack. ER cleared me. Lightheaded, dizzy, skin numbness and tingling, palpitations, fatigue, and overall bundle of nerves. Cut the pill in half, did little to reduce the side effects. Within a week, I quit taking it. Blood pressure on it 103/71. Blood pressure off it 118/79. I was a Tourette's kid in the 80s, so I did the circuit of meds... haldol, clonidine, orap, you name it. Dystonia, low BP, rapid weight gain. I know I am sensitive to medications. Hopefully, this post helps someone."

For High Blood Pressure "Started losartan (50 mg 2/day, 25 mg HCTZ 1x) Feb 2021 after a hypertensive crisis (200/120). Within two weeks, dropped to normal levels. Lots of dizziness, constipation, and malaise, combined with tingling in extremities; subsequently cut HCTZ to 12.5 mg. BP sits at roughly 100/60-110/70 with regular daily exercise and dietary changes. Still experience slight dizziness from time to time with episodes of low blood pressure (90/50); plan to confer with Dr. soon to consider a lower dose."
