Desmopressin Acetate Tablets are for oral use only. They are available in two strengths, 0.1mg and 0.2mg. They contain Desmopressin acetate, an antidiuretic (reduces urine production).

They are used:

  • to treat primary nocturnal enuresis (bedwetting) in children (from 5 years of age) and adults (up to 65 years of age)
  • to treat cranial diabetes insipidus (a condition that causes extreme thirst and the continuous production of large volumes of dilute urine) IMPORTANT: This should not be confused with diabetes mellitus (sugar diabetes)
  • to treat post-hypophysectomy polyuria/polydipsia (extreme thirst and the continuous production of large volumes of dilute urine following surgical removal of the pituitary gland).

  • 2) Before you take Desmopressin Acetate Tablets

Do not take Desmopressin Acetate Tablets:

  • if you have a serious heart or kidney disease
  • if you are taking diuretics (water tablets)
  • if you are allergic to any of the ingredients listed in section 6 of this leaflet
  • if you drink unusually large quantities of fluids, including alcohol
  • for bedwetting, these tablets should not be used if you are under 5 years old or over 65 years old

If any of these apply to you, or if you are not sure, contact your doctor before taking Desmopressin Acetate tablets.

Taking Desmopressin Acetate Tablets with food or drink:

  • fluid intake must be limited to a minimum from 1 hour before taking the dose at bedtime until the following morning (and, in any case, for at least 8 hours)
  • avoid swallowing water while swimming to prevent a build up of water in the body.
  • You should avoid drinking large amount of fluid while you are being treated with Desmopressin Acetate Tablets, as this could lead to build up of water which dilutes the salt in the body. This is a serious problem and may lead to fits.
