3 Proper Usage

Desmopressin injection must be administered by a nurse. It is a shot given into a vein or under your skin. For patients with diabetes insipidus, this medication may be given at home. Your doctor or nurse can demonstrate how to give self-injections. 

If you are confused about how to do it, ask your healthcare provider. It is important that you understand the steps clearly. They will also show you where to give the shots. You should remember to use different sites every time so that skin problems do not develop. Follow your doctor’s instructions if he/she asks you to decrease your fluid intake. 

The dosage will depend on your condition. So it’s different for each individual. Adults and children with diabetes insipidus should get 0.5 to 1 mL divided into 2 doses, preferably in the morning and evening. If you forgot a shot, give yourself the dose as soon as you remember. 

However, you should skip it if it’s almost time for the next shot. Store the solution in the fridge and not in the freezer. When you throw away syringes and needles, use a puncture-proof container.
