Cough from ACE-I

Q: Although withdrawal of treatment is the choice of treatment for angiotensin converting enzyme inhibitors (ACE-Is) induced cough, which drugs may help to reduce the symptom?

Answer:  The treatment of choice in ACE-I induced cough is the withdrawal of the offending drug. But in case if cough lingers on despite the discontinuation of drug or in the situations where withdrawal is not feasible theophylline, inhaled sodium cromoglycate, picotamide(a thromboxane antagonist) may be helpful in alleviating the symptom. 

To note, in some cases cough may last up to three months after withdrawing the offending drug.
