An Introduction to Tiazac Side Effects
As with any medicine, side effects are possible with
Tiazac® (
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 easily be treated by you or your healthcare provider.
(This article covers many, but not all, of the possible side effects with Tiazac. Your healthcare provider can discuss a more complete list of Tiazac side effects with you.)
Common Tiazac Side Effects
Tiazac has been thoroughly studied in clinical trials.
In these studies, the side effects of a group of people taking the drug are documented and compared to the side effects of another group not taking the medicine. As a result, 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 Tiazac side effects included:
- Swelling or water retention in the hands, feet, or lower legs -- in up to 15 percent of people
- Dizziness -- up to 10 percent
- Headaches -- up to 8 percent
- Indigestion -- up to 6 percent
- A sore throat -- up to 6 percent
- Infections -- up to 6 percent
- Pain -- up to 6 percent
