DES: CAPSULE

General Drug Information and Indications

Desmopressin acetate is a synthetic form of the hormone vasopressin. Vasopressin, which is also called anti-diuretic hormone, is responsible for regulating how much water the body retains and how much urine the kidneys produce. Animals that do not make enough vasopressin have a medical condition known as Central Diabetes Insipidus. Desmopressin acetate is the treatment of choice for central diabetes insipidus in both dogs and cats. Because there are a number of different causes of increased water consumption and increased urine production, desmopressin acetate can also be used to help make a diagnosis.

A less common use for desmopressin acetate is in animals with an inherited bleeding disorder called type 1 Von Willebrand’s disease. In this instance it may be used by a veterinarian at the time of surgery.  

Like many other drugs in veterinary medicine, this drug is not FDA approved for use in animals and is not available from a veterinary pharmaceutical manufacturer. Instead, it is compounded by a specialty pharmacy.

How to Give this Medication

Give this medication to your pet exactly as your veterinarian prescribes. If you miss giving your pet a dose of desmopressin acetate, give the next dose as soon as you remember or, if it is close to the next scheduled dose, return to the regular schedule. Do not double dose to catch up.
 
Desmopressin acetate is usually given as an eye drop. Your veterinarian may give it by intravenous injection or by injection under the skin. It can not be given by mouth.

When desmopressin acetate is used to treat central diabetes insipidus, it is generally given once or twice a day in the conjunctiva (lower eyelid sac).

Wash your hands after giving your pet this medication.

Side Effects

Be sure to discuss any side effects with your veterinarian immediately.

Desmopressin acetate can cause irritation to the eye or conjunctiva.

Too much desmopressin acetate will cause swelling and water retention. At the beginning of treatment you may need to work with your veterinarian to arrive at the appropriate dose for your pet.

Desmopressin acetate should not be used in animals that are prone to forming blood clots. This includes most animals with underlying heart disease.

Desmopressin acetate has not been studied in pregnant dogs or cats. Large doses have been given to pregnant laboratory animals without apparent harm to the fetus. It should only be used if the benefits outweigh the potential risk.
