Desmopressin sublingual pills

What is desmopressin?

Desmopressin is used to treat nighttime bed-wetting, central diabetes insipidus, and increased thirst and urination caused by head surgery or head trauma.
Desmopressin is a man-made form of a hormone that occurs naturally in the pituitary gland and regulates how the body uses water.
Desmopressin may also be used for purposes not listed in this medication guide.

Warnings

You should not use desmopressin if you have severe kidney disease or hyponatremia (low sodium levels in your body). You also should not take Nocdurna if you have severe thirst, uncontrolled hypertension, heart failure, high levels of a hormone that causes fluid retention, or if you take a diuretic or use steroid medication.
Limit your intake of water and other fluids while you are using desmopressin. Drinking too much water may lead to a serious, life-threatening electrolyte imbalance.
Call your doctor right away if you have signs of low sodium: headache, confusion, muscle cramps, severe weakness, vomiting, loss of coordination, and feeling restless or unsteady.

How should I take desmopressin?

Your doctor may perform blood tests to make sure you do not have conditions that would prevent you from safely using desmopressin.
Follow all directions on your prescription label and read all medication guides or instruction sheets. Use the medicine exactly as directed.
Limit your intake of water and other fluids while you are using desmopressin. Drinking too much water may lead to a serious, life-threatening electrolyte imbalance.
Fluid restriction is especially important in children and older adults using desmopressin. Follow your doctor's instructions about the type and amount of liquids you should drink.
If you were switched from desmopressin nasal spray to desmopressin tablets, wait at least 12 hours after your last nasal dose before you take your first tablet.
Take the sublingual tablet 1 hour before bedtime. Place the tablet under your tongue and allow it to dissolve. Empty your bladder before going to bed.
Your blood pressure will need to be checked often and you may need frequent blood tests.
Store at room temperature away from moisture, light, and heat.

What should I avoid while taking desmopressin?

While treating nighttime bed-wetting, avoid drinking anything within 1 hour before your bedtime dose of desmopressin. Do not drink anything until the next morning, or at least 8 hours after you have taken the medicine.
Avoid coffee, tea, cola, energy drinks, or other sources of caffeine before bedtime.
Also avoid drinking alcohol before bedtime.
