How to use DDAVP tube:
Use DDAVP tube as directed by your doctor. Check the label on the medicine for exact dosing instructions.
- An extra patient leaflet is available with DDAVP tube. Talk to your pharmacist if you have questions about this information.
- DDAVP tube should only be used in the nose. Do not get it in your eyes or mouth. If you get it in your eyes, rinse at once with cool tap water.
- Open DDAVP tube by pulling the plastic tag on the neck of the dropper bottle. Break the security seal and remove the plastic cap. Twist off the small, ridged seal from the top of the dropper. Save this to reseal the bottle to prevent leakage between doses.
- Fill the soft plastic rhinal tube (nose tube) with the correct dose of medicine. Insert the tip of the medicine dropper bottle downward into the end of the nose tube that is marked with an arrow. Squeeze the medicine from the dropper bottle into the nose tube until the medicine reaches the correct dose mark on the nose tube. Use constant pressure when squeezing the dropper bottle to avoid air bubbles in the tube. Remove the dropper bottle from the nose tube by withdrawing it quickly downward.
- For adults and older children: Hold the nose tube about Â¾ inch from the end and gently insert it into 1 nostril until the tips of your fingers touch your nose. Place the other end of the tube in your mouth. Hold your breath, tilt your head back slightly, and blow through the nose tube with a short, strong puff.
- For very young children: Place the nose tube only far enough into the child's nostril so that the medicine does not run out. An adult may need to blow the medicine into the child's nose.
- After use, replace the top of the ridged seal onto the tip of the dropper bottle. Cover the resealed dropper bottle with the plastic cap. Wash the tube in water and shake thoroughly until no more water is left. Allow the tube to air dry. It can be used again for the next dose.
- If you miss a dose of DDAVP tube, use it as soon as possible. If it is almost time for your next dose, skip the missed dose and go back to your regular dosing schedule. Do not use 2 doses at once.
Ask your health care provider any questions you may have about how to use DDAVP tube.
