Stopping lisinopril - I've been coughing constantly since stopping lisinopril. What can I do? Cetrizine helps. Since this cough is due to lisinopril, it will go away in few days. But if you can't tolerate it you can try antihistamines like Benadryl (diphenhydramine) or cetrizine. If the cough persists even after a week of stoppage of Lisinopril then you might need to see your doctor.
