Coughing After Taking Antihypertensives? You Might Be Experiencing ACE Inhibitor Side Effects

Modern medicine explains that among standard hypertension therapies, drugs known as angiotensin-converting enzyme inhibitors, or ACE inhibitors, can induce a dry cough. These medications lower blood pressure by suppressing angiotensin-converting enzyme, which relaxes and widens blood vessels. However, this same ACE enzyme breaks down bradykinin in addition to converting angiotensin I to angiotensin II. When you take an ACE inhibitor, bradykinin cannot be properly cleared and accumulates in the body. This buildup stimulates specific receptors in the airway mucosa, irritating the respiratory tract without an inflammatory response and triggering a dry cough. Coughing occurs in roughly 5 to 20 percent of people taking an ACE inhibitor, appearing more frequently in women. The symptom typically emerges within several weeks to months after starting the prescription, persisting day and night as an incessant dry cough often accompanied by an itchy, scratchy throat. Discontinuing the drug generally allows the cough to fade within days to weeks. Even so, consulting your doctor for an accurate diagnosis is essential to rule out other potential causes, such as reflux esophagitis, asthma, or chronic bronchitis. You should never stop or alter your medication on your own, as this can severely disrupt blood pressure control. Discussing an alternative prescription or finding ways to soothe the throat with your doctor is the safest approach. Just as Donguibogam describes dryness, drug side effects can become more pronounced when general immunity or the autonomic nervous system is out of balance.
