Doctors' Answers to "Frequently Asked Questions" - Ddavp
Answer: DDAVP is the abbreviation for desmopressin acetate. This is a synthetic analogue for the hormone in your pituitary which is responsible for concentrating urine,vasopressin. It is available as a nasal spray and an injection, I am not aware of a pill form. Anyway, it concentrates the urine and patients with a deficiency cannot concentrate urine. Hence, they have large volumes of urine. They can keep up with it by drinking lots of water. It can run in some families as an inherited problem(rare but exists) or after trauma or tumors in the pituitary(common after surgery for other tumors for example). Alcohol is to be avoided since alcohol acts to block the effect in the kidney and lowers the concentration of urine(which is why drinking a couple of beers causes you to urinate and why you get dehydrated after lots of alcohol). There is no direct problem with the alcohol except that it works to counter the effect of the ddavp.
