For Angina "I was prescribed this drug, isosorbide mononitrate, after going to the hospital with angina. I was sick of using GTN spray, as it gave me sore throats and headaches. I only took these tablets, 3x30 mg doses over 3 days, and had to have a week off work. The side effects were dizziness, couldn't open my eyes or see properly, wasn't sure what I was doing, tired all the time - worst thing I've ever taken. Back to the spray and aspirin now. I'd rather have a few minutes of angina than all the side effects of Carmil (UK brand of isosorbide). Never again. Just hope my appointment to have a stent fitted arrives soon. Been waiting since March...."

For Angina "Started on isosorbide mononitrate 30 mg yesterday. Have had angina, SOB (shortness of breath), right hand and arm icy cold, since quad bypass in 2017. Immediately after taking the first dose felt 'yukky', had the headache, dizzy, very tired, took an ibuprofen and sat in a recliner for about 2 hours, then felt much better and was able to walk in my yard with no chest pain (first since surgery)! My right hand is warm! This morning took the med then went back to bed for an hour. Slight headache right now. Will take ibuprofen again. Still no chest pain or SOB. Right hand was cold, but is now warm again! I pray this continues."

For Angina "I have been taking isosorbide mononitrate 30 mg tablets for a little over 2 months now. For the first 4 to 5 days, I did experience headaches, however, they did subside. I have now started to experience a headache every now and again, though. I have also started to have the same chest pain again, which had completely gone away until now. My biggest complaint and concern is that I find myself EXTREMELY tired every single day for the past 2 weeks! It does not matter if I sleep 8 or more hours, I still wake up feeling like I have had no sleep at all! I can sit down on my couch or at the kitchen table and fall asleep sitting straight up and have slept that way for hours! I don't understand this, but other than that, I'm okay with the medicine."

For Angina "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."
