Irbesartan Side Effects: An Overview
As with any medicine, side effects are possible with
irbesartan (
Avapro®). However, not everyone who takes the drug will experience problems. In fact, most people tolerate it quite well. If side effects do occur, in many cases, they are minor and either require no treatment or can be treated easily by you or a healthcare provider. Serious reactions are less common.
(This article covers many, but not all, of the possible side effects with irbesartan. Your healthcare provider can discuss a more complete list with you.)
Serious Side Effects of Irbesartan
Some irbesartan side effects should be reported immediately to your healthcare provider. These include but are not limited to:
- Unexplained skin rash
- Itching
- Unexplained blisters or peeling of the skin
- Unexplained swelling of the head or neck (including the face, lips, tongue, or throat)
- Wheezing
- Difficulty breathing or swallowing

Irbesartan has been studied extensively in clinical trials, with thousands of people worldwide being evaluated.
In these studies, side effects are always documented and compared to those that occurred in a similar group of people not taking the medicine. Based on these studies, the most common side effects with irbesartan included:
- Fatigue -- in up to 4 percent of people
- Diarrhea -- up to 3 percent
- Heartburn or indigestion -- up to 2 percent
- Dizziness -- up to 10 percent (in people taking irbesartan for diabetic nephropathy).
