Angiotensin receptor blockers (ARBs) are generally well tolerated, with the most common side effects being elevated potassium levels, headaches, dizziness, fatigue, a rash, diarrhea and low blood pressure. A cough is much less likely to occur with ARBs than with ACE inhibitors (many people who experience a cough with ACE inhibitors can tolerate ARBs).

More serious side effects are rare and include kidney failure in those who suffer from stenosis (narrowing) of the arteries supplying the kidneys, liver failure, allergic reactions and swelling of the tissues, including the face and throat, which can compromise breathing.
