Irbesartan Side Effects
Many different side effects may develop during treatment with irbesartan. Those that were most commonly reported include dizziness, diarrhea, and heartburn. Other less common reactions include gout, angina, and stroke. More severe side effects of irbesartan that should be reported to your healthcare provider immediately include unexplained skin rash, wheezing, or difficulty breathing.
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.)
Some irbesartan side effects should be reported immediately to your healthcare provider. These include but are not limited to:
- Unexplained skin rash
- Unexplained blisters or peeling of the skin
- Unexplained swelling of the head or neck (including the face, lips, tongue, or throat)
- Difficulty breathing or swallowing
- Dizziness, lightheadedness, or fainting spells
- Decrease in the amount of urine produced.
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).
