Which of the following is NOT a common side effect of ACE inhibitors?

Myalgia is considered less commonly associated with the use of ACE inhibitors compared to the other listed side effects. ACE inhibitors, which are mainly prescribed for conditions like hypertension and heart failure, are well-known for causing a dry cough due to the accumulation of bradykinin. This cough occurs in a significant percentage of patients and is often a reason for discontinuation of the medication.

Hyperkalemia, or elevated levels of potassium in the blood, is another common side effect because ACE inhibitors can interfere with the hormone aldosterone, which helps regulate potassium levels in the body. Fatigue can also occur as a side effect, potentially related to changes in blood pressure and fluid balance that occur with ACE inhibitor use.

In contrast, myalgia—muscle pain—does not have a strong association with ACE inhibitors. While it can occur in patients due to various reasons, including drug interactions or underlying conditions, it is not recognized as a frequent side effect specifically linked to ACE inhibitors. This distinction underscores why myalgia is the correct answer to the question about which symptom is not a common side effect of this class of medication.
