Lisinopril-Induced Cough: Incidence and Onset Duration
Lisinopril, an angiotensin-converting enzyme (ACE) inhibitor, is well known for causing a persistent, dry cough in a significant number of patients. The cough is typically described as dry, nonproductive, and persistent, often accompanied by a tickling or irritating sensation in the throat 64. The onset of lisinopril-induced cough can vary, with reports indicating that it may begin within days of the first dose or may take several months to develop after starting therapy 46.
Duration of Lisinopril-Induced Cough After Discontinuation
The duration of the cough after stopping lisinopril is generally short. Most studies agree that the cough usually resolves within a few days to a few weeks after discontinuing the medication. Specifically, the cough typically remits within a few days, but in some cases, it may take up to 1 to 4 weeks for the cough to completely disappear after stopping lisinopril 46. This resolution period is consistent across different ACE inhibitors, including lisinopril.
Factors Influencing Cough Duration and Incidence
The likelihood and duration of cough can be influenced by several factors. Women and nonsmokers are more likely to report lisinopril-induced cough, and the incidence is higher in these groups compared to men and smokers . The cough persists as long as the drug is taken and resolves after discontinuation, with no evidence suggesting long-term persistence once the medication is stopped 46.
Comparison with Other Antihypertensive Agents
Studies comparing lisinopril with other antihypertensive agents, such as valsartan, losartan, and hydrochlorothiazide, show that the incidence of cough is significantly higher with lisinopril. However, the duration of cough after stopping lisinopril remains similar, with most patients experiencing resolution within a few weeks 15.
Conclusion
Lisinopril-induced cough is a common side effect that typically begins within days to months of starting therapy and resolves within 1 to 4 weeks after discontinuation. The risk is higher in women and nonsmokers, but the cough does not persist long-term after stopping the drug. Alternative antihypertensive agents may be considered for patients who develop this side effect.
