Isosorbide Mononitrate CR Oral Uses
This medication is a nitrate drug. It is used to prevent chest pain (angina) and reduce strain on the heart in patients with heart disease (coronary artery disease). Isosorbide mononitrate relaxes and widens blood vessels so blood can flow more easily.
This medication will not relieve chest pain once it occurs. It is also not intended to be taken just before certain activities (e.g., exercise, sexual intercourse) to prevent chest pain. Other medications may be needed. Consult your doctor for details.
How To Use Isosorbide Mononitrate CR Oral
Take this medication by mouth usually twice daily, or as directed by your doctor. Take the first dose of the day upon awakening and the second dose 7 hours later. It is important not to change the times you take this medication unless directed by your doctor. During treatment, the long time period between the second dose on one day and the first dose on the next day is necessary to make sure the drug works well.
Use this medication regularly in order to get the most benefit from it. Remember to use it at the same times each day.
Do not stop taking this medication without consulting your doctor. Some conditions may become worse when the drug is suddenly stopped. Your dose may need to be gradually decreased.
Although unlikely, when used for an extended period, this medication may not work as well and may require different dosing. Contact your doctor if this medication stops working well (worsening or more frequent chest pain).
