For High Blood Pressure "I took this drug diltiazem for about 10 days- it was working well until day 6- when it started to tighten my stomach and cause a feeling of bloating and constipation. Just in time for a 4 hour plane flight too! Not comfortable. I had to quit taking it due to this feeling- I've had 5 stomach surgeries due to ruptured appendix complications, so being bloated and constipated isn't especially fun for me. Too bad since the drug otherwise was working well- I had improved energy and could stay awake longer than with the beta blocker I had been on, and my sex drive had returned also! So quitting it was disappointing- I have so many bad side effects to many of these BP drugs. So back on the Bisoprolol I go, even though I feel like a 90 year old man on it & basically castrated! May get my doc to prescribe Diovan for me next month, unless he has a remedy for this stomach tightness/bloating that Diltiazem had given me."

Cardizem CD (diltiazem) for Atrial Flutter "I have been diagnosed for 3 years with tachycardia and the doctor does not know why I have such a high heart rate. Was put on this medicine. Still at rest my heart rate is over 100. Yesterday he upped the dosage from 180 to 240mg. I'm so tired of having this problem and taking this medicine. "

For Atrial Fibrillation "I think this slows my heart rate down too much and causes the extra beats to be thrown in. I've found that when I'm at rest is when I have the issues. I've gotten a 2nd opinion and was switched to metoprolol. We'll see if that works better. "

For Atrial Flutter "After my heart began racing several times with a pulse of 180 my doctor put me on Diltiazem (135). However, after a couple of months my heart began racing again, so the doctor upped the Diltiazem to 180. I had been experiencing breathing problems and thought it was related to my asthma flaring and a wet winter. Now with the increased Diltiazem I am having even greater difficulty breathing with pretty severe shortness of breath. I think it is most likely related to the drug. Now seeking medical follow up."

For High Blood Pressure "I had an attack of tachycardia that was caused by eating apricot seeds. Taken to the hospital and treated for 125-135 heart and feeling like I was shaking and panicking. They prescribed Metoprolol and sent me home after treatment, I felt fine the next day and then had rapid heart rate again and had a flash of anxiety. I took the metoprolol and tried to get in to see my Army doctors. After a 10 day wait and being extremely anxious and a nervous wreck I got to see my doctor. He took me off Metoprolol and gave me Diltiazem, no blood tests, no other testing. The Diltiazem makes me feel foggy, dizzy, and at first chest tightness and palpitations. I'm desperately working out to lose weight and get off this drug."

Dilt-XR (diltiazem) for Heart Failure "I was told I have a-fib but I only felt the bad ones. When THEY HIT IT SCARES ME BUT but in the hospital with a 33 hour AFIB MODE, it stopped when they gave me Cardizam. Now I only get mild very short attacks that I can feel. So soon, in 3 weeks I'm asking for a higher dose. It lets me live a normal life at age 77"

For Supraventricular Tachycardia "I take this medication at 120mg for heart tachycardia. I went into ER with 165bpms 3 years ago and honestly I thought I was going to die. Uncontrolled blood pressure and anxiety and abuse of energy drinks. Please don't be a victim of energy drinks like me. Well Doctor put me on this for the past 4 years and my palpitations have gone from every week to every 6 months excellent medication and also makes you relax."

For Atrial Fibrillation "I've been taking 180mg timed-release dilt capsules for two years after my 95%-effective catheter ablation for atrial flutter. I still get mild and transient afibs most mornings at 5 a.m. or so. They stop after ten minutes or when i sit up or get up to use the restroom. I think the vagus nerve responds to bladder pressure and sends a wrong signal to the heart to act up. I'm on low dosage by prefernce. Perhaps I'll ask for higher dosage if the transient episodes start to last longer or feel more severe. I can barely feel the "quivering' sensation that afib causes in my chest so I am happy for now."

For High Blood Pressure "I was on Adizem-XL 200mg but didn't control blood pressure, also on perindopril erbumine and flecainide but didn't have problems apart from blood pressure going up. Put on Adizem-XL 240mg and now have gingivitis, it's horrible and the BP consultant recognised it but said Adizem-XL didn't cause it. That is the only thing that changed and dentist has xrayed teeth and always have regular checks, no sign of problems. Just very sore inflamed gums that bleed when I brush teeth, and very tired, enlarged neck glands and dizzy. I'm very fed up with the lack of concern, have no confidence"

For Atrial Flutter "Diltiazem was started due to difficulty tolerating flushing of neck, chest and groin with Amylodipine. It has been effective at controlling palpitations but this improvement was not noted immediately after starting medication. It seemed to take over a week after switching from Amylodipine to Diltiazem before relief from palpitations were noted. Please note! If you take thyroid hormone replacement, be aware to avoid taking Diltiazem at same time as thyroid medicine. My thyroid labs (TSH) have been steadily increasing over last 6 months (revealing that my dose of Synthroid has not been adequate) until it was discovered this week that this unwanted change in thyroid labs has been caused by taking Diltiazem daily at same time as Synthroid."

For Supraventricular Tachycardia "I have taken this for over a 18 months. It works great. I have Atrial Fibrillation and Tachycardia. I had previously taken Rythmol for six months - it added 20 pounds to me and I was eating less and less. The diltiazem is working great, started on 120mg but just recently went to 180mg. Having a few more episodes but am also dealing with breast health issues - it could very well be from anxiety from this rather than actual heart issues. Very hard to discern. Would recommend this over Rythmol - hands down, and in the last 6 months have lost 10 of the 20 Rythmol put on me."

For Supraventricular Tachycardia "I have been taking Diltiazem ER for 3 months, initially 90mg twice daily. It has really helped with my svts. My blood pressure was still a bit high so my dose was increased to 120mg twice a day which has helped but I have now developed an itchy eczema like rash on my face and a sore sunburn like rash on my neck despite only being in the sun for a very short time. Has anybody else had this sort of reaction to Diltiazem?"

For High Blood Pressure "I was given Metoprolol Succinate, Eloquis, and Atorvastatin after being admitted to the hospital with a-fib. I am a healthy 42 year old, non smoker male. The metoprolol is the worst medicine I have ever taken. I suffered for about two months with horrible side effects. Went back to ER because I thought I was having a heart attack about a week after starting meds. Stomach pain, dizziness, depression, anxiety, increased BP, shakes, bloated feeling, tiredness, and sharp pains in chest. After about two months another cardiologist told me to stop taking the metoprolol and switch to diltiazem ER 120mg once a day. It took about a week but all the side effects stopped. I started feeling like a human being again. I had muscle twitches for a week as my body flushed the metoprolol. Diltiazem has been a God send for me but obviously not for others. Just listen to your body and tell your doctor if a medicine isn't working."

Cartia XT (diltiazem) for Supraventricular Tachycardia "I have had SVTs for about 18 years and was switched from Calan SR to this drug. I had no issues for about 4 years until recently when I was told that Cartia had been discontinued. Now I am on Diltiazem for 3 months and have already had 2 episodes in a month. I am going to try my hardest to get back on Cartia"

For Atrial Flutter "I've been on a low dose of diltiazem for about 5 years and it was working, then I recently had some vasospasms and they upped my dose twice. When I got up to 240 mg I started having stomach issues, lack of appetite, and worst of all unbearable depression. I've always dealt with anxiety but deep unbearable depression is not something I've ever had and I couldn't function. I hope this helps others when working with training the right meds."

Diltiazem Hydrochloride CD (diltiazem) for High Blood Pressure "I had been on Diltiazem CR (controlled release) 240mg per day, took it every morning faithfully. I am now in Spain where they do not have the controlled release but gave me Diltiazem regular release 60mg. The first day I took all four at once in the morning and it dragged me down so far I about collapsed. Now, I'm trying to regulate it, taking one 60mg in the morning, then one at noon, then one about 4pm, then one about 8pm. I have heard that some blood pressure medicines shouldn't be taken before one goes to bed. Does anyone know about this one?"

For Atrial Fibrillation "The cardiologist prescribed 120 mg from the Hospital it definitely helps to calm my heart down when my heart rate is high, but, the dose is too high and knocks me out for around 16 hours. So I tried an experiment, I opened up a capsule and only used half. I take it an hour before bedtime which gives me a great night's sleep, usually I have to take a prescription sleep medication, to sleep. If I take it during the day, it takes away all my energy, I can't function or makes me go to sleep, this is a warning to anyone on this medication, for some people it may not have any effect on them."

Tiazac (diltiazem) for High Blood Pressure "360mg/daily: severe thirst, dry eye, dry mouth, itchy skin. Went to have a 2nd opinion and that MD put me on 180mg ER twice daily with no ill effects. I must have been sensitive to an agent within the 360 mg SA compound."

For High Blood Pressure "I had been using Losartan 75mg and was getting heart palpitations and feeling lousy. I switched to a different cardiologist and they recommended diltiazem with a dosage twice a day, one in the morning and one in the evening. My blood pressure had been as high as 170/108 at the doctor's office but was on average 125/90 at home. I was worried about the side effects but switched and have seen no side effects. In fact, my heart palpitations stopped and my blood pressure is becoming more regulated. I'm now seeing average readings in the evening of as low as 100/70 with an average now of 120/85. I exercise 30-45 minutes a day and also stopped adding salt to my diet. I also eat less meat and intermittent fast - only eating in a 6-hour time period. I also have no side effects such as swelling, dizziness, or fatigue. I strongly recommend this."

Cardizem (diltiazem) for Atrial Flutter "after Beta Blockers failed to work, and made me gain 20 lbs in 90 days. Dr then tried Verapamil , While that did work better not 100%. After a 6 months , Then became allergic to it. Rare side effect. Then Dr put me on Cartia XT, after a day or 2 , I felt alot better. Cartia XT is really is controlling my PVCs from Left Vertical, 8 months going now and no side effects yet. Works better than Verapamil for me."

For Atrial Fibrillation "I was put on this medicine in combination with Atenolol for frequent PVCs. I've had an irregular heartbeat for 20 years, and have been on several different meds. This combination of beta blocker/calcium channel blocker seems to be working. I have had some PVCs here and there, but definitely fewer since the diltiazem was added. I do feel like I've put on a few pounds since starting the medicine - like I'm puffy in the face and my ankles have been swelling. Other than that, I'm OK."
