Side Effects of Verapamil: An Introduction
As with any medicine, there are possible side effects with
verapamil hydrochloride. However, not everyone who takes the medication will experience side effects. In fact, most people tolerate it quite well. When 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 verapamil. Your healthcare provider can discuss a more complete list of verapamil side effects with you.)
Common Side Effects of Verapamil
Verapamil has been studied thoroughly in clinical trials, in which the side effects of a group of people taking the drug are documented and then compared to 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 verapamil side effects included:
- Constipation -- in up to 7.3 percent of people
- Dizziness -- up to 3.3 percent
- Nausea -- up to 2.7 percent
- Low blood pressure (hypotension) -- up to 2.5 percent
- Headache -- up to 2.2 percent.
