Isosorbide Dinitrate Summary 

 Isosorbide dinitrate is a medicine used to treat chest pain, heart failure, and high blood pressure by helping blood vessels relax and widen, which makes it easier for the heart to pump blood and get enough oxygen. It works by turning into a substance in the body that opens the blood vessels and lowers the pressure on the heart. Common side effects include headaches, feeling dizzy, flushed skin, and low blood pressure, especially when starting medicine. People with certain heart problems, very low blood pressure, recent head injuries, or those taking medicines for sexual health like sildenafil should avoid it, because it can cause a dangerous drop in blood pressure. Drinking alcohol while using it can make dizziness worse, and although most foods are safe, it’s best to avoid grapefruit juice unless your doctor says it’s okay.
