Headache is reported as the most frequent side effect of isosorbide mononitrate, sometimes occurring in over 50% of patients when first starting the medication. While this can be bothersome, it is often considered a sign that the medication is working by dilating blood vessels and typically subsides with continued use. Understanding and managing this and other side effects is key to a successful treatment regimen.
