For High Blood Pressure "I have an irregular heartbeat, so my doctor put me on Cartia XT 240 MG (diltiazem). I started having a racing heart, uncontrollable shakes, heated face, felt like my face was going to burn off, couldn't get out of bed, and went to the ER 3 times in a week. My kids finally looked up side effects to this drug, and I had them all. It was awful. I finally got off of it onto the plain Diltiazem. It works 100 times better without crazy side effects. I suggest you look up side effects before taking anything new. I know I will. I felt like I was dying."

For High Blood Pressure "I have been taking Cartia XT 180 (diltiazem) every other day for several years. It controls my BP and prevents SVT. There is a shortage (Aug 2019) so the pharmacy substituted Cardizem CD. Since then I have experienced episodes of rapid heart rate, increase in pitch and intensity of tinnitus and hot flashes. I just had my Thyroid levels tested today to see if my dose of Synthroid is too high. (After EKG was normal). If it isn’t the Synthroid, then it must be the Cardizem. Very frustrating - I don’t feel myself at all."
