"I take a whole host of medication for high blood pressure - and some narrowing of arteries (as determined by an angiogram). I also cycle quite a lot - 50-100 miles/week. I found that when I took the isosorbide mononitrate, I would get very much out of breath, and it would make me very weak. I effectively stopped taking them over time and feel much better with no symptoms of angina."

"I had a terrible experience on this drug. It was supposed to control my chest pain but instead worsened my pain. I also had migraines. In spite of these adverse reactions, my doctor wants me to try it again. No thank you."

Isosorbide mononitrate "Was started on Imdur 60 mg for nightly chest pain following 2 angios and 5 stents. Initially, it was very effective, and I did not experience any chest pain/tightness, but a fortnight later, the effect is wearing off, and I am again experiencing chest pain at night."

"My brother was put on this medication on Wednesday; yesterday (Saturday) he was taken to the ER with side effects from this. He felt like his chest was caving in, severe headache, couldn't get warm enough. His blood pressure went severely low, and his heart rate went high. He is still in the hospital today for observation. Would not recommend this drug to anyone."

Isosorbide mononitrate "Was prescribed this medication by a new cardiologist while hospitalized to help with spasms associated with Prinzmetal's (variant) angina. So far, I feel a difference in my condition, but will form a more solid opinion when I'm on Imdur a bit longer."

"My husband was given isosorbide 2 years ago as he got so very anxious, etc. The hospital thought that this would stop him from having an angina attack, which it has, but the side effects are awful. He suffers from headaches, does not eat like he used to, and he loved his hot cooked home food, so that has gone, and will just eat a bowl of cereal for supper. We have a sandwich and a piece of cake at lunchtime, breakfast, and that is all. The other side effects include headache, feeling dizzy, not sleeping any longer than 2 hours each night, also complains of having a hot head, but not every day. He just sits and doesn't feel like doing anything, and I can understand if he is feeling like this. Also, his eyes run in the morning, but I think this is because he does not have enough sleep. I would desperately like him to come off these awful tablets, as his tests show that his heart, thank God, is alright, and his blood pressure now is where it should be. He also takes 1 aspirin each morning. Please help."

"Was prescribed this after a heart attack and had a stent in. Have been taking just 30 mg of Carmel XL, and today will be my last day. Pounding headache, nothing can help. Can only lie down, every tiny movement hurts. Can't see properly. Not having angina attacks since surgery, so don't see the point of this medicine, surely a spray when needed is better? Would not recommend, but feel I have been misprescribed by the hospital."

"I am only 39 and had my first heart attack on Jan 5th, 2017, caused by a 100% blockage and an 80% blockage. I go back on Jan 31st for another stent, and today, 1/28/17, is my first day taking the 30 mg isosorb mononitrate ER, and it's horrible so far. Bad headache all day, sick to my stomach, and heart palpitations all day. Really feeling like I should go to the ER. Do not recommend this medication."

"This medication was prescribed to help increase blood flow through a blocked artery (85-90% of the circumflex), although I'm fairly functional. I am also on Metoprolol for blood pressure and a recently prescribed statin, along with baby aspirin. I took 1/2 of my 30 mg pill yesterday and got an annoying headache. Today I took the full pill first thing in the morning and now have a really bad headache bordering on the feel of a migraine, minus the nausea-though I do feel a little queasy. I feel so bad that I am considering discontinuing it-though thanks to some of the reviews here, I will try to take it for a week before making that decision in case I can become accustomed to it. I have stable angina, so at this point, the horrible side effects are not worth it for the supposed benefit. I'd rather get winded and take it slower than be in the state I'm in."

Isosorbide mononitrate "Went to the ER last Sunday for chest pain/angina attack, couldn't walk up the stairs without feeling like I was having a heart attack, so the new cardiologist put me on Imdur 30 mg. The first day I was fine, the second day about 3 to 5 hours after taking it I came down with an ungodly migraine. I have been on it now for 6 days, and 5 of them I have had a migraine - not cool. But I have to admit that I'd rather have the headache because it has been heavenly being able to walk around with zero heart attack-like pain."

"I have been treated since heart attacks and bypass surgery. I also suffer from Raynaud's disease, and before isosorbide, my hands caused so much pain. Turning white, blue, then red. Very painfully if it’s cold, even indoors, I wear gloves. But since isosorbide, my hands stay pretty normal. Love it."

"Was prescribed the ER tablet. Took it for three months, no problems. Then the excruciating headaches began, which were relieved by nothing... 24 hours a day. All I could do was stay in bed. When the pill was in effect for about only 8 hours a day, before the onset of headaches, I felt great, but when it wore off, I couldn't do anything. Everything caused chest pain. After the fourth month, the headaches were still excruciating, so I stopped taking it. Have had only one episode of angina since then, which seems to be brought on by stress. I just find I have to be careful not to overdo physically, and I do fine. This med has so many side effects you can't even count them all. I wondered if it was causing some strange adverse effect in my brain because the headaches didn't start until I had been on it about 3 months. Asked my cardiologist about this and why the delayed headache. His answer, 'I don't know.' Big help that was."

"I was prescribed this medicine - isosorbide 30 mg. First, I thought something was wrong with me. After a couple of days, I started having headaches, dizziness, nasal pain, and pain spread across my arm, shoulder, and back. Trying to walk around the house, I cannot balance well, afraid of falling down. I need to stay in bed. I felt fatigued. I found out this was a side effect of the isosorbide medicine. What kind of medicine tries to accomplish more harm than help? Dreadful medication."

"I have been on this drug for 6 months. 30 mg. I have not experienced any side effects. Recently increased the amount to 60 mg, and the first few days I was very dizzy and felt weak. I am confident I will get used to the higher dosage."

Isosorbide mononitrate "Was put on Imdur (1/2 30 mg tab) after heart catheterization. Worst 6 days of my life. I tried to wait out the week for my system to acclimate to the meds, but I couldn't do it. I would take the meds at 6 a.m. and by 8 a.m. I would have the worst headache. Nothing helped. I tried everything: Tylenol, heat packs, cold packs, even my migraine cocktail. By day 6, it was so bad I had to go to the ER for a shot of Toradol. I was completely down for 6 days. Doctor finally discontinued Imdur and is trying something else. This may work for some, but not for me."

"I have unstable angina and always felt very much at risk and vulnerable. Started taking isosorbide mononitrate and the first four days had terrible headaches. I knew this was possible and persevered. The headaches reduced in severity and within 10 days had stopped. No more severe chest pain. I have had a few mild episodes of chest pain, but not enough to use my GTN spray. I feel so much better and secure. Glad I persevered with them."

"Dr. prescribed Ismo 30 mg, and after taking it, I felt so much head and neck pain, but I slept right away. The next day, no headache was felt, but my neck and shoulders were really hurting. Then, after a few minutes, my heart started pounding fast, and I felt like I was losing my breath. This went on for hours. I could not sleep because of difficulty in breathing, and my heart was palpitating through the night. I can't sleep. It felt like my heart was racing. I feel restless and like I have insomnia. I stopped the med after that 1 dose. I will go to another doctor for a second opinion."

"After leaving the hospital, I was prescribed isosorbide mononitrate. I took 1, and the headache was so severe I couldn't sleep, and it lasted 8 hours. Had to take aspirin to get it manageable. Waited a day to understand what just happened. On the third day (today), I cut the pill in half and tried again. At 10 am, I took it, and by 12:30, I started getting dizzy, and the headache returned like a three-penny nail. It is now 6 pm, and it is now manageable. Seriously, I DON'T think I can deal with this."

"Was on a 30 mg tablet with no side effects, now on 60 mg and get the most horrendous headaches. Paracetamol, ibuprofen, or any other pain reliever is useless as they don't work. Would have thought that in this day and age they could produce something that has no side effects."

"I've been 3 years on 60 mgs now, and the last few months started to feel very ill. I have frozen shoulder, and after 3 months of acupuncture and chiropractor, it's not getting better. Along with headaches, back ache, and a general constant feeling of life being drained out of me. This situation is making me very depressed and feeling hopeless. I did try to cut the pills in half for a week and became so ill and unable to stand I have had to go back on them. I will now try to wean off them in smaller doses as I cannot keep existing like this. The cardiologist had said no way in stopping taking them, he was adamant. Then when I said I'd had frozen shoulder for the last few months, he was 'oh, you got frozen shoulder, ok, stop taking them.' It was ONLY THEN that I looked at side effects, and frozen shoulder is or can be one of them... It's been SO debilitating, I'm at my wits' end to think this could largely be because of medication... leaves me totally frustrated."

"I’ve got angina and have been prescribed this drug, 10 mg twice a day. Horrendous headache that just lasts all day, every day. Taking paracetamol, but I’m worried about having to take too much. Will ask my GP about it at check-up."

"I’ve been taking the medicine since 2019 after a heart attack for angina. 30 mg once a day. Unfortunately, if I stop it, there is a withdrawal, and the pain comes back. So I need to keep on taking it. Headache and dizziness are bad."

"Unfortunately, I had such severe migraine headaches that lasted all day, at least 24 hours. I tried to take a half while still in bed with migraines. I have a blocked artery that can't be stented and had a bypass in 2019. I had blurred vision and nausea. I honestly don't know what to do."

"I've been using the 30 mg ER version for about a week. My symptoms were pain in the shoulder and chest when hiking. The first few days had significant headaches (at least for me, who never gets them) that neither Tylenol nor aspirin could alleviate. Also felt tired and weak. Must say a turnaround from the symptoms occurred on the 5th day, which was yesterday. Tiny, briefly felt headache dissipated with Tylenol. The cool thing is that since 2-3 days ago, no longer any left shoulder (which sometimes radiated to the chest) pain occurs when hiking up a fairly steep incline or two, nor the heavy, labored breathing (though there will always be some of that-I mean I'm 74 and realistic). I hope this will be enduring."
