DDAVP (Desmopressin) Dosage and Side Effects
DDAVP Tablets reduce the amount of urine so a child's bladder will not fill up; therefore, a child will not wet the bed at night.
Proper Use of this medication
How many DDAVP Tablets should be used?
Take the medication at the dose prescribed by your physician 1 hour before bedtime. Use the following dosage plan or one that has been recommended by your physician.
Step 1: For the first 3 nights:
Take 1 tablet (1×0.2 mg) 1 hour before bedtime.
If the child is dry for 3 nights taking 1 tablet each night, continue this way. Do NOT increase the dose.

What should I do if ...?
The child is still wetting the bed:
Make sure the child is taking the correct number of tablets each night.
Limit the number of drinks the child has after supper.
If it's still not working, call your doctor.
As with all medicines, side effects may be experienced. With DDAVP Tablets, these may include headache, dizziness, rash, and mild abdominal cramps. These have occurred usually when the medication is being adjusted. Once you are taking the right amount of medicine for your condition, these side effects will usually go away. Tell your doctor about any side effects you experience.
Warnings and Precautions
Infrequently, high doses of DDAVP have produced transient headache and nausea. Nasal congestion, rhinitis, flushing and mild abdominal cramps have been reported. These symptoms disappeared with reduction in dosage. Please contact your physician should your child experience any side effects. For DDAVP to work at its best, it is very important to limit the number of drinks the child has after supper, especially 1 hour before bedtime. As most children sleep between 8 to 12 hours, further fluid restriction is not required. In the event the child wakes up during the night, liquid intake should be restricted.
