The GP prescribed desmopressin for DS (9) saying it was for short term use only and not to use it for more than a week or it will lose its effectiveness. This contradicts what I've read on the web, and when I queried it with the pharmacist he said he'd never heard about only using it for a week. Even on his database, he could not find any information to tie in with what the GP said.
How long were your children on desmopressin? Did it stop the bed wetting long term? DS wets about 2/3 nights, and it's hereditary, so prime candidate for desmopressin it seems.
