When This Medicine Should Not Be Used
How to Use This Medicine
- Take your medicine as directed. Your dose may need to be changed several times to find what works best for you. An overdose can be dangerous. Follow directions carefully so you do not get too much medicine at one time.
- This medicine is for use only in the nose. Do not get any of it in your eyes or on your skin. If it does get on these areas, rinse it off right away.
- To use:
- Keep the spray in the child-resistant container until ready to use.
- If you are using the nasal spray for the first time, you will need to prime the spray. To do this, you should release four sprays into the pouch. Now it is ready to use.
- If you have not used the medicine for more than 5 days, re-prime by spraying once into the pouch.
- Before using this medicine, gently blow your nose to clear the nostrils.
- Insert the tip of the bottle into the nose. Point towards the bridge of the nose and tilt the bottle slightly.
- Press down firmly on the finger grips until you hear a "click" sound and the number in the dose counter window adds up. This confirms a spray has been taken.
- Return the spray bottle to the child-resistant container after each use.
- After using the nasal spray, wipe the tip of the bottle with a clean tissue and put the cap back on.
- This medicine should come with a Medication Guide. Ask your pharmacist for a copy if you do not have one.
- Missed dose: Take a dose as soon as you remember. If it is almost time for your next dose, wait until then and take a regular dose. Do not take extra medicine to make up for a missed dose.
- Store the medicine in a closed container at room temperature, away from heat, moisture, and direct light.
- Disposal: Ask your pharmacist about the best way to dispose of medicine that you do not use. Throw away any spray bottle and start using a new one if you have used 8 sprays or if it has been 60 days or more since it has been used. Dispose any used, partially used, or unneeded spray bottles by emptying and spraying the remaining solution into the pouch. The sealed pouch and the empty bottle should be placed in a child-resistant container before discarding it in the trash can. Wash your hands with soap and water right away after handling the pouch.
