Short description:
Nasal desmopressin can cause severe and life-threatening hyponatremia (low blood sodium). tell your doctor if you have or have ever had a low level of sodium in your blood, are thirsty all the time, drink large amounts of fluids, or have syndrome of inappropriate antidiuretic hormone (SIADH; condition in which the body makes too much of a specific natural substance that causes the body to retain water) or kidney disease. Also tell your doctor if you have an infection, fever, or illness of the stomach or intestines with vomiting or diarrhea. Tell your doctor if you experience any of the following during your treatment: headache, nausea, vomiting, restlessness, weight gain, loss of appetite, irritability, fatigue, dizziness, muscle cramps, seizures, confusion, loss of consciousness, or hallucinations .
Tell your doctor if you are taking a loop diuretic ("pills that cause water to be expelled through the urine") such as bumetanide, furosemide (Lasix), or torsemide; an inhaled steroid such as beclomethasone (Beconase, QNasl, Qvar), budesonide (Pulmicort, Rhinocort, Uceris), fluticasone (Advair, Flonase, Flovent), or mometasone (Asmanex, Nasonex), or an oral steroid such as dexamethasone, methylprednisolone (Medrol), or prednisone (Rays). Your doctor will probably tell you not to use desmopressin nasal if you are using or taking one of these medications.
Keep all appointments with your doctor and lab appointments. Your doctor will order certain tests to monitor your sodium levels before and during your treatment to check your body's response to desmopressin nasal.
Talk to your doctor about the risks of using desmopressin nasal.
