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 this medication.
Blood pressure and increased heart rate: Desmopressin injection can cause changes in blood pressure and a fast heart rate. If you have vascular headaches (e.g., migraine), heart failure, heart disease, or high blood pressure, you may be more sensitive to these effects. Talk to your doctor about any concerns you may have.
Effectiveness: Desmopressin injection is not effective in controlling excessive urination caused by kidney disease. Your doctor will monitor you and your response to desmopressin injection while you are taking this medication.
Fluid and electrolyte balance: Fluid intake should be adjusted in order to reduce the possibility of water retention and low levels of sodium in the blood, especially in children and seniors. Talk to your doctor about how much fluid intake is appropriate. Your doctor will monitor you closely while taking this medication. People who are dehydrated should wait until their water balance has been adequately restored before taking desmopressin injection. Desmopressin should be used with caution by people who have cystic fibrosis as they are prone to low levels of sodium in the blood.
Tolerance: There are reports of changes in response to this medication over time. Some people may experience decreased responsiveness, while others may experience a shortened duration of effect. If you notice this, contact your doctor.
Pregnancy: This medication should not be used during pregnancy unless the benefits outweigh the risks. If you become pregnant while taking this medication, contact your doctor immediately.
Breast-feeding: It is not known if desmopressin injection passes into breast milk. If you are a breast-feeding mother and are taking this medication, it may affect your baby. Talk to your doctor about whether you should continue breast-feeding.
Children: The safety and effectiveness of this medication have not been established for infants younger than 3 months of age for use in preventing or stopping bleeding associated with hemophilia A or von Willebrand's disease.
