How to use Minirin spray:
Use Minirin spray as directed by your doctor. Check the label on the medicine for exact dosing instructions.
- An extra patient leaflet is available with Minirin spray. Talk to your pharmacist if you have questions about this information.
- Minirin spray 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.
- The pump must be primed before the first use. To prime the pump, point the nozzle away from yourself and others and press down 4 times.
- If the pump has not been used for over a week, reprime the pump by pressing down once.
- To use, gently blow your nose. Tilt the bottle so that the tube inside draws from the deepest amount of medicine.
- Sit down and tilt your head back slightly. Place the tip of the spray container into the nose. Using a finger from your other hand, press against the opposite nostril to close if off. Breathe gently through the open nostril and squeeze the spray container. If you are using more than 1 spray, wait for 1 to 2 minutes between sprays.
- Alternate between nostrils with each spray as directed by your doctor.
- After using the medicine, rinse the tip of the spray unit in hot water and dry with a clean tissue to prevent contamination.
- Replace the cap on the bottle after each use.
- The bottle contains 50 sprays. Keep track of how many sprays you use, and throw the bottle away after 50 sprays. Do not try to use more than 50 sprays from the bottle, because you may not get the correct amount of medicine in each spray. Do not try to transfer the remaining medicine to another bottle.
- If you miss a dose of Minirin spray, 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 Minirin spray.
