When taking Aceon, a cough is a possible side effect (it is a common side effect with all ACE inhibitors). However, a cough does not appear to occur as frequently with Aceon as it does with other ACE inhibitors. Keep in mind that your healthcare provider cannot know beforehand whether you will have a side effect with a medicine that you have never taken.
If you notice a cough while taking Aceon, talk to your healthcare provider. If the cough continues, he or she may recommend switching to another ACE inhibitor or blood pressure medicine.
