An Introduction to Cardizem CD Side Effects
As with any medicine, side effects are possible with Cardizem CD® (diltiazem hydrochloride); however, not everyone who takes the drug will experience side effects. In fact, most people tolerate it quite well. If side effects do occur, in most cases, they are minor and either require no treatment or can be treated easily by you or your healthcare provider.
(This article covers many, but not all, of the possible side effects with Cardizem CD. Your healthcare provider can discuss a more complete list with you.)
Common Side Effects of Cardizem CD
Cardizem CD has been studied thoroughly in clinical trials, in which a group of people taking the drug have side effects documented and compared to another group not taking the medicine. This way, it is possible to see what side effects occur, how often they appear, and how they compare to the group not taking the medicine.
In these studies, the most common Cardizem CD side effects included:
- Headache -- in up to 5.4 percent of people
- Slow heart rate (bradycardia) -- up to 3.3 percent
- Swelling or water retention, especially in the hands, feet, or lower leg (edema) -- up to 2.6 percent
- Weakness -- up to 1.8 percent.
