Isosorbide Dinitrate (ISDN) belongs to a class of medications called Nitrates. Nitrates are used to prevent and treat the symptoms of angina (chest pain). Angina is caused by lack of blood supply and oxygen to your heart. Nitrates work by relaxing blood vessels so that more blood and oxygen is supplied to the heart.
When you take this medication regularly on a long-term basis, it can help to treat angina by reducing the number of heart attacks that occur.
Nitrates can also be used with other medications for the treatment of heart failure, a condition where the heart is weak and is unable to pump enough blood to the rest of the body.
The symptoms of a drug allergy include one or more of the following:
If you experience any of these symptoms, you should stop your medication and see your healthcare professional immediately.
Inform your healthcare professional if:
Do not take Sildenafil (Viagra®), Tadalafil (Cialis®), Vardenafil (Levitra®) if you are taking this medication. When Sildenafil, Tadalafil or Vardenafil is taken with Nitrates, your blood pressure can lower greatly, resulting in dizziness, lightheadedness or fainting. In some cases, death has been reported when Sildenafil was taken with Nitrates.
If you miss a dose, take the missed dose as soon as you remember. If it is almost time for your next dose, take only the usual dose. Do not double your dose or use extra medication to make up for the missed dose.
Throw away all expired medications.
Pack this medication into a black trash bag and seal it tightly before throwing into the rubbish chute or bin.
