Side effects are unlikely unless overdosing is repeated.
If Desmopressin does not seem to be working contact the doctor. Most people using Desmopressin find it causes them no problems. Occasionally some people suffer from headache, stomach-ache, nausea, blocked or runny nose or nose bleeds. Allergic reactions to the preservative such as skin rash, itching or sore nose can occur rarely. If you experience one or more of these side effects or any other undesirable effects please tell a nurse or doctor.
