Diltiazem Overview

Diltiazem is a nondihydropyridine (non-DHP) member of the class of drugs known as calcium channel blockers, used in the treatment of hypertension, angina pectoris, and some types of arrhythmia. It is a benzothiazepine, which differentiates it from the other classes of non-DHP calcium channel blockers such as the phenylalkylamines. It is also an effective preventive medication for migraine.

Diltiazem - Inwood 180mg sa cap (NDC# 4335330889)
I was using Cardizem CD 180MG caps but the VA changed me to DILTIAZEM (INWOOD) 180 MG SA CAP. Is your 180MG SA also a 24 hr. time release cap like the Cardizem? Thank you for your help...RC ## Hello, RC! How are you? This website does not manufacture any medications. It is an information only resource. And yes, what you've been given is just a generic for what you were already taking and you should follow your doctor's dosing and usage instructions. The SA stand for sustained action, so it means the same as the CD that was listed with the name brand. This medication is most commonly used to treat high blood pressure and certain cardiac conditions. Side effects to this medication may include nausea, dizziness, headache, dry mouth and hypotension. Is there anything else I can help...

diltiazem er/xr and cartia xt
Is there a difference between these 2 meds I was on diliazem 120 er/xr for 4 years and had no problems and now the med was changed to cartia 180 xt and I have headaches congestion which aggravates my ashma and stomach aches ## Hello, Clare! How are you? I'm very sorry about the problems that you're having. They are the same, Cartia XT is just the name brand. It seems odd that it would cause congestion headaches which aggravate your other conditions. Are you allergic to any inactive ingredients that you know of? Are you on any other medications? Have you consulted your doctor?

Diltiazem CD by PAR vs Diltiaz ER.
taken diltiazem cd cap par for years new pharmacy filled rx with diltiaz er teva asked phrmcst he said same are they? 240 mg. AFIB. ## Hello, DesrtDrmr! How are you? From what you've listed in your post, they are the same and have just been manufactured by different companies. With generics, it's common for your pharmacy to switch, depending on which company was offering the cheapest price at the time they needed to restock their supply. Side effects to this medication may include nausea, dizziness, headache, hypotension, lowered heart rate and stomach pain. Is there anything else I can help with?

Diltiazem 240mg C Cap Acta
I need the side effects of this high blood pressure drug ## Diltiazem is a calcium channel blocker, so it may cause side effects, such as nausea, headache, hypotension and dizziness. You can read more about the medication and additional side effects here: Is there anything else I can help with? ## How long does it take for side effects to go away after the drug is discontinued ## Theresa, it can vary, depending on the dosage and how long you were taking it. I am very sensitive to medications and usually found that when I suffered bad side effects and discontinued one, it took 2 weeks at a minimum for them to wear off and the max was usually about 4 weeks. Are there any other questions or comments? ## This is the worst drug I have taken. My fingers are swollon and itch so bad it feels an...

extreme fatigue
I am taking Diltiazem ER 180 mg a day for atrial fibrillation. My question is whether I can take this in the evening so it does not make me so tired during the day? Thanks. ## Hi Charlie, Based on my research, the dosing indications for Diltiazem ER don't actually specify whether or not you're supposed to take it during the day or at night. It only mentions taking it "once daily" and doesn't really go into any further detail from there. So in my opinion, it sounds like it should be fine to take it at night as long as you remain consistent with one particular approach. Initially, it's also possible that you may feel a slight difference from altering the timing of your dose, but everything should level out shortly thereafter. I hope this helps! ## Hello, Charlie! H...

what is the difference between diltiazem 180mg and norvasc 5 mg
I need to know the difference of diltiazem 180mg and norvasc 5 mg . Are they similar ## Looks like both medicines are used for almost the same thing. Were they prescribed to you by the same doctor? Reference Pages: Diltiazem, Norvasc ## Difference between Diltiazem SA Caps and Diltiazem ER(dilt-XR) Caps? ## ER or XT stands for Extended Release, which means the drug is released slowly over a certain period of time, rather than all at once like regular release medications. ## Dark green, gray capsule with # R-2579 on it ## w/hat is the difference between narvasc and ditiazem ? do they act differently on the system. since they are both calcium blockers. Can they cause bone problems?

Should I Take Diltiazem?
Beginning about 15years ago, I became aware that I was having palpitaions, later diagnosed as PVCs. It appeared to me that they were slowly becoming more frequent over this time period, but dramatically increased about 2 months ago. Approximately 30% of my beats were PVCs when I wore a monitor for 48 hours about two weeks ago, but no tachicardia. 15 years ago I was only having periods of frequent PVCs about twice a year, and they only lasted a couple hours each time. Way back then, a doctor prescribed atenolol (sp?) for another condition. Upon taking it I immediately started having continuous periods of PVCs that lasted the entire three days that I took the medication. (I discontinued.) During this recent long period of PVCs, I was prescribed a small dose of Metoprolol (Met) daily -- 12...
