Before you begin using a medication, be sure to inform your doctor of any medical conditions or Allergies you may have, any medications you are taking, whether you are pregnant or breast-feeding, and any other significant facts about your health. These factors may affect how you should use Pro Ismn (Isosorbide-mononitrate).
Drowsiness/reduced alertness: Pro Ismn (Isosorbide-mononitrate) may cause faintness or dizziness. Do not drive, operate machinery, or perform other potentially hazardous tasks until you have determined how Pro Ismn (Isosorbide-mononitrate) affects you.
Heart disease: Isosorbide-5-mononitrate may cause some symptoms of heart disease to become worse. If you have heart problems caused by not enough oxygen being available for the heart or other organs of the body, discuss with your doctor how Pro Ismn (Isosorbide-mononitrate) may affect your medical condition, how your medical condition may affect the dosing and effectiveness of Pro Ismn (Isosorbide-mononitrate), and whether any special monitoring is needed.
Low blood pressure: Some people who take Pro Ismn (Isosorbide-mononitrate) experience symptoms of a severe decrease in blood pressure, such as weakness or dizziness. This is more likely to happen when rising suddenly from a sitting or lying position. If it persists or if you faint, contact your doctor. People who have or have had heart disease, Stroke, "mini-stroke", or are at risk of experiencing low blood pressure (e.g., dehydration, taking medications for high blood pressure) should discuss with their doctor how Pro Ismn (Isosorbide-mononitrate) may affect their medical condition, how their medical condition may affect the dosing and effectiveness of Pro Ismn (Isosorbide-mononitrate), and whether any special monitoring is needed.
Tolerance: With continued use, isosorbide-5-mononitrate may stop having beneficial effects because the body gets used to it (i.e., develops a tolerance). Call your doctor if at any time you feel that your angina attacks are getting worse or happening more often.
Withdrawal: Stopping Pro Ismn (Isosorbide-mononitrate) suddenly may occasionally aggravate chest pain or other symptoms of angina.
