Why does my dDAVP not always work properly?
If your dDAVP treatment works poorly sometimes, the reason is probably poor absorption of the drug. If you are taking the dDAVP by mouth, you may be able to improve consistency by taking the tablet on an empty stomach or by increasing the size or frequency of the dose. If you are taking the nasal spray, try blowing your nose before each dose. If that does not help, consult your doctor about increasing the size or frequency of the dosing.
