For Supraventricular Tachycardia: "Was on Atenolol 25mg, once a day, had bad leg cramping, some dizziness, it wasn't helping my palpitations then Cardiologist switched me to Bystolic 5mg I had again dizziness, vivid dreams and feeling fuzzy. Started Diltiazem 30mg 3 times a day as needed and I started with one a day and palpitations and accelerated heart are controlled, I only experienced fatigue, shortness of breath and sometimes nightmares but has helped me feel better though..."

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 Atrial Fibrillation: "Worked to convert afib than dropped blood pressure too low. Doc adjusted med but I had the worse headaches everyday just in the week I was on it. I had to lay down due to headache and very tired feeling each day. Looks like it works for many who have posted. Trying metoprolol. See it has a less favorable review but my hubby has taken it for years with no side effects. Hoping for a great outcome."

Cartia XT (diltiazem) for High Blood Pressure: "I've been on Cardia XT for 1 year... Yes, pass the side affects please... Occasional dizziness, light headiness, some minor weight gain, but watching what I eat -- getting into the gym... GIVE UP THE SALT --- Processed foods are also sodium filled....The fatigue is awful on most days - I just have to get that nap in -- but preferably not in Atlanta traffic... but overall -- it definitely does it's job! blood pressure is excellent most days --- My blood pressure was 200/120 triggering A-FIB landed me in ER/Intensive Care last November for 4 days... YIKES!!!! This morning's pressure was 112/80... AMAZING!!!"

Cartia XT (diltiazem) for Atrial Flutter: "I had a terrible reaction to Cartia XT's formulation of Cardizem, when my usual manufacturer, PAR who also makes Cardizem capsules, was not in stock at my pharmacy. So they substituted Cartia XT's formulation of Cardizem; I began having extreme racing, more than usual AF, and it continued to recur within about an hour after taking it each day. It was very alarming, because PAR manufacturer of Cardizem never gave me a bad reaction and I had been taking it for years. Pharmacists who try to tell you that all generics are the same but that is misleading. the main ingredient prescription drug must be the same as the brand; but the manufacturer can vary the remaining ingredients; and it is very difficult to find out what they are."

Cartia XT (diltiazem) for Supraventricular Tachycardia: "Took this medication to help my SVT. Made my heart skip beats and I felt like I was going to have a heart attack. Worst experience of my life. Never helped lower my heart rate. Lopressor never worked for me either."

For High Blood Pressure: "Hi, 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 Atrial Fibrillation: "I was diagnosed with Sinus Tachycardia a few years ago. My resting heart rate was usually 130-140. Resting heart rate!! I was put on a medication that made me so tired I could barely function. After a month on that I insisted on switching and they gave me Dilt XR 120mg. I noticed some slowing of my heart rate and absolutely NO side effects. Still my heart rate was running around 100 and would get like hot flashes if I did much moving around, which made work miserable. I have increased my dosage to 360mg and I feel so much better. Pulse is running in the 70s and the hot flashes and sweating have almost gone away."

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: "Have had intermittent A-Fib for several years, with no needed intervention. Recently began having chest pain and shortness of breath so went to my cardiologist. Was in continuous A-Fib, so he started me on Cardiazem. Worst side effects I have ever experienced. Nausea, vomiting, diarrhea, lightheadedness, fell once, profuse sweating, general malaise, just felt horrible. This was after only 3 tablets. No medication changes. Started on Coumadin, and had taken this for years without problems. Called Dr. and med. stopped. Just now beginning to overcome those dreadful side effects. BUT I do recommend this medication for those who can take it. My sister has been on it for years for A-Fib and has done great, only has rare A-Fib"

For Atrial Fibrillation: "180 mg is my friend. When I have an AFIB incident, about 4x per year, I double up the med and I convert soon after. Before I was educated, I ran to the hospital and they gave me cardia in IV form. NO bad side effects at all. Highly recommended"

Cartia XT (diltiazem) for High Blood Pressure: "Taking the slow release, 120 mg version. I take it at night about 30 minutes before bedtime. Averts any dizziness since I am going to bed to sleep. BP has been good 125/80 generally. resting pulse of about 60. Thankfully I am optimal weight and I exercise 4 to 5 times weekly, mostly a 2 mile walk each time and about 50 situps. Drinking lots of water to stay hydrated. mild constipation so I eat a cup of yogurt at least every other day."

Cardizem (diltiazem) for Atrial Fibrillation: "I have had two episodes of lone a-fib, one 15 yrs ago and one six months ago. For the earlier episode I was placed on Toprol, Digoxin and Warfarin - it was HORRIBLE, I've never felt so sick in my life. This time, I was placed on 240 mg of Diltiazem and Xarelto. I have been on both for six months with the only minor issue being a bit of excess gas, small price to pay to keep the a-fib away."

Tiazac (diltiazem) for Atrial Fibrillation: "Hi, I've been taking 240 mg of tiazac every evening for the past 11 years after a trip to the ER at 37 years old. I waited about 2 hours to call the paramedics, but after being unable to climb the stairs I decided to call them. My heartbeat was still well over 200 when I got to the ER. I was lucky to be in good shape because it is well possible my heart would not have held on at that rate for that long. Tiazac works great for me. At first I tried 2 pills per day, but did not work very well. After a few weeks my doctor switched me to long release 240 mg. I'm still with it 11 years later and training for a triathlon in the fall and 25 k next spring. If your conditions allows it, exercise ! and drink decaf. ! (for me at least)"

For : "Been taking cartia xt, 120mg twice a day since 2011 for pvc's, pac's, occasional svt, and non-sustained a-fib unrelated to the chest pains I get quite frequently. It helped a lot, but the doctor recently upped my dosage to 180mg twice a day for chest pain that I am now experiencing from coronary spasms due to a myocardial bridge diagnosed via catheterization! Hopefully, the increase in dosage will stop all these terrifying spasms."

Cartia XT (diltiazem) for Supraventricular Tachycardia: "I am currently taking Cartia XT 120mg once a day, and it is a mixed bag for me. I am still experiencing an elevated HR multiple times per day, and very light headed all day long. I do not feel right at all. I have also tried metropolol and lisinipril, having the best results from the latter, but it did not address my HR."
