About 1.5 months ago, my doctor changed one of my high blood pressure medication from Atenolol (beta blocker) to
Diltiazem (calcium channel blocker) since Atenolol caused insomnia. Ater the change, I do sleep much better. However, I have noticed that I have occasional minor coughing. Has anyone have similar experience with Diltiazem?
Any side effects of Diltiazem that you experienced ? Thank.
