For High Blood Pressure "Using 30 mg diltiazem 1/2 tab twice a day for high blood pressure. I am sensitive to all drugs and I got side effects of itchy throat, stuffy nose, ankle edema, forgetfulness, nightmares. Also bursts of odd cardiac rhythm. Have to take 12 hour decongestant and 12 hour antihistamine to survive which in turn raises b/p. Will ask for change of med, usually MD just rolls her eyes."

For Atrial Fibrillation "For years (More like forever) I kept getting diagnosed with panic attacks since by the time I would get to the ER the "episode" had stopped. Last year I had the worst and longest episode I'd ever experienced. By the time I got to the ER my heart rate was still in the 190's. At 41yrs old, I Finally found out it had been A-Fib the last 20 years. Was prescribed Diltiazem (Cardizem) 60mg every 6hrs and I love it! A little bumpy in the beginning. Sensitivity to sunlight and tiredness/dizzy but not bothersome to the point I wanted to stop. After about a week the mild side effects had passed and well, It's just awesome. I highly recommend to help control A-Fib symptoms."

For Supraventricular Tachycardia "I suffered for about a year with constant PVCs (premature ventricular contractions) and was eventually diagnosed with PSVT (paroxysmal supraventricular tachycardia) and benign PVCs. I had never had this anytime in my life until I turned 39 and my doctor has mentioned it could be hormonal related. I was prescribed Dilitiazem 120 mg taken once daily and within 3 days my PVCs were barely noticeable. As time continued, it worked even better and also controlled my heart rate. My resting heart rate before the medication was 100 or above and after taking the medicine, It was around 75. I went in for a 3 month check up and my bp was high and so the doctor decided to increase dosage to 180. And boom, I was back to square one. Constant PVCs and fast heart rate in the 100s. After two weeks I called my doc and she lowered my medication back down again and I must monitor BP. Hopefully I can get back on track."

For High Blood Pressure "Was taking 180mg for 2 weeks and was not getting a decrease in BP. Was really no difference from not taking any meds. I had heart flutters and body aches where I thought I had one of the worst fibromyalgia bouts ever. Doctor doubled my dose. In one week the body pains/aches worsened, my blood pressure went up, and my heart flutter worsened. Also gave me headaches and my nails have never grown so fast in my life! 1st day off Dilitiazem and my body aches are already going away as are the heart flutters. 3 weeks of unsatisfactory treatment and would not recommend this drug to anyone. Going to Atenolol."

For Atrial Fibrillation "I am 60 years old and started taking diltiazem 240mg about 11/20/2012 along with Xarelto 20mg and Sotalol 80mg twice a day after being diagnosed with atrial fibrillation. On 12/21/2012, I had an electrocardioversion that did not cure the atrial fibrillation. Today (1/28/2013), I visited my Cardiologist and my pulse is down to the low 60's, my BP is normal and the irregular heartbeat is under control. He said to discontinue the Xarelto, but to continue with the Diltiazem and Sotalol. He is monitoring my heart for the next 24 hours."

Cartia XT (diltiazem) for Supraventricular Tachycardia "I have been taking Cartia XT for supraventricular tachycardia for about 5 years. This medication has completely controlled the racing heart that I used to get from time to time. I've had no side effects. A big bonus is that eating ice cream used to trigger the racing heart beat. Now I can eat ice cream."

Cardizem CD (diltiazem) for Atrial Fibrillation "I was happy with medication, as I did not have as many side effect, but on day 17 of taking it, I developed a rash on my stomach, next day chest and lower back, third day neck and face. It was the only thing I was doing differently, so I looked up its side effects. Rash was listed and could occur within 10 to 20 days. It is a Saturday, so as advised online I stopped the medication. I hope this a temporary condition, and I can begin again, or an alternative can be found."

For High Blood Pressure "I will give this medication a couple more days, but so far it has been awful for me because of the side effects. I am constantly dizzy/lightheaded and feeling slightly sick to my stomach. As I have a daily 60 mile round-trip commute to and from work, that's scary. It also appears to be affecting my depth perception. "

For High Blood Pressure "I was on Cardizem LA for a little over a month. After a couple of weeks I began having waves of depression, pounding heart, dizziness, and all of these symptoms worsened. The last week I was on this med, I noticed a white blister in my mouth, which spread and became very sore. Along with that, I had blisters show up on my fingers with peeling skin. I researched other reviews here and figured it had to be the Cardizem. I have stopped taking it, and have already noticed a big difference."

Cardizem (diltiazem) for Raynaud's Syndrome "Recently diagnosed. Has helped tremendously on circulation and fatigue. I was amazed that I was able to grab a handful of snow for a short time without triggering an onset of usual numb painful cycle. I started off with 180mg and now on 300mg daily. I now have my thermostat set lower and get hot wearing long sleeves now! I'm a happy camper for the first time in years. "

Cardizem CD (diltiazem) for High Blood Pressure "I developed white spots and sores in my mouth just a few days after starting this medication. I thought it was my partial plate doing it, made five trips to the dentist for adjustments, nothing worked, it just got worse. on an impulse I researched the side affects of this med, and there you go - white spots and sores in the mouth. The dentist started treating me for thrush, so now I am on steroids, and a mouth wash for that. Needless to say, I am no longer taking the med. I was also experiencing fatigue and dizziness."

For Atrial Fibrillation "I am a 69 year old male , 6'4" currently about 210 #.About six months ago experienced afib when first diagnosed was given Metoprolol and within a few days was extremely weak and could hardly breath. My cardiologist changed to diltiazem and it was like night and day. I had plenty of energy and the breathing issues ended. Since being diagnosed with afib I have stopped drinking alcohol, began a low carb diet that includes lots of vegetables, protein and omega 3s. All in all a pretty healthy diet. I also have lost about 30lb in that time period. At my 6 month Doctors check up prior to meeting with my cardiologist I commented about discomfort in my breasts, and was diagnosed with Gynecomastia. Fasting blood sugar 104 to 132. Concerned"

For High Blood Pressure "Diltiazem for High Blood Pressure: Atrial Fibrillation: Atrial Flutter I took Diltiazem before surgery and then continued it after for high blood pressure. It worked just fine for a while although the 12 hr only lasted for 4- 5 hours in my case. Then I started getting toothaches and really bad gingivitis. I did have gingivitis already. I also started feeling lousy and only by coincidence did I stop taking the Diltiazem. Two day later my toothaches were gone and my gums stated clearing up. I still thought it was a coincidence. I restarted Diltiazem again and the same thing happened again."

For Supraventricular Tachycardia "I'm 40 yrs old, and have had around 10 episodes of aroxysmal supraventricular tachycardia (psvt) in my lifetime. My heart rate gets up to around 250 beats per minute each episode. Before taking this medicine, I had to go to the emergency room, and get a shot of adenosine, to get my heart to slow down. I talked to my doctor about having to go to the emergency room each time, because I could do nothing to slow my heart rate on my own. She prescribed me cardizem 30 mg tablets, to take when I have an episode, I take 4 tablets at the onset, and within 10 to 15 minutes my heart rates subsides. This medication has been a godsend and works great for me."

For Supraventricular Tachycardia "I was diagnosed with SVT about 7 months ago. I was initially put on atenolol but switched over due to it causing weight gain and constipation. The diltiazem has been fine, but I still get a couple of short episodes. Before medication, they used to last 30+min and my heart would race to 200 bpm. Now that I'm on medication, I've had two episodes that lasted 30secs at most. Today, I just had an episode that lasted 15 minutes, but it was not as intense as it used to be. I'm considering the ablation, just because it's inconvenient to have this happen while I'm at work. However, I've been told that if I had an episode on diltiazem, I can take another pill to stop it."

Cardizem CD (diltiazem) for High Blood Pressure "HYPERTENSION DUE TO UNCONTROLLED INTRACTABLE PAIN. Enlarged Heart with small Mitral Valve leak. 30 mg x 2 per day. Worked well for about a month, then Extreme GI, and Eye Dryness occurred to the point it changed my vision and affected my receding gum lines. EVERY ONE OF THESE HYPERTENSION DRUGS HAVE GI SIDE EFFECTS AND DRYNESS that will affect your vision. Why can't I have what I really need PAIN CONTROL, then I wouldn't need a Hypertension drug."

Cardizem CD (diltiazem) for Supraventricular Tachycardia "I am on 240 mg once a day, Been taking meds since Feb 2011. Works GREAT for treating the heart problem only I have side effects. A week after starting the medication at the lowest dosage I developed sinus congestion.

Medicine was increased again and now the congestion/cough/wheezing is getting unbearable. I took myself off the medicines and within 4 days all my symptoms were GONE!"

Cardizem (diltiazem) for High Blood Pressure "Started this medication over a year ago, and it has helped keep my heartbeat regular. I had an episode where my heart rate was over 200bpm, and had to go to the ER in an ambulance from my doctor's office. It has not repeated, thank goodness, and I had no side effects from this medication, which I take with Zestril (which I'd been taking for many years before)."

For High Blood Pressure "Got off labetolol as it only made me sleep 20 hours a day ? Gave me peeling hives, and memory lost . Now taking diltiazem and I’m calmer and my skin completely cleared up, I can smell foods again. Memory cleared up have energy. And my libido has come back. Sometimes I have hot flashes that’s ok. No racing of heart or chest pains. Bathroom problems are normal. Diltiazem has been a miracle, very little bad side effects. Can't believe I waited fifteen years to stop suffering, and try other BP meds."

Diltiazem Hydrochloride CD (diltiazem) for High Blood Pressure "I've been on Diltiazem for decades, beginning with 240mg. After cardiac ablation a few years ago, my dose was reduced to 180mg. Over the years with several prescription plans, I've used virtually every branded and generic version. I can't discern any difference between them. I'm now purchasing this drug mail-order, as the cash price is less than the copay from my Part D plan! Diltiazem CD/ER keeps my BP in the normal range, with no noticeable side effects."
