The usual recommended dose of nafarelin nasal spray is one spray (200 µg) into one nostril in the morning, and one spray into the other nostril in the evening, for a total daily dose of 400 µg. The doses should be approximately 12 hours apart. Some women may require higher doses (e.g., 800 µg per day).
Treatment should be started between the second and fourth day after the beginning of menstrual bleeding. During the first 2 months of using nafarelin, vaginal bleeding, also known as breakthrough bleeding, may occur. The length of treatment is usually for 6 months, unless otherwise instructed by your doctor.
Ask your doctor or pharmacist to teach you the proper way to use this nasal spray. If you are using this medication for the first time or using a new bottle of nafarelin you will need to prime the spray pump. To prime the spray pump, turn the tip of the bottle away from you, put 2 fingers on the "shoulders" of the spray bottle and put your thumb at the bottom of the bottle, and push down 7 to 10 times until you see a fine mist appear.
Gently blow your nose to clear your nostrils before each use. If you sneeze during or immediately after the dose, contact your doctor or pharmacist for advice.
After each use, clean the spray tip by holding the bottle in a horizontal position and rinsing the spray tip with warm water while wiping the tip with your finger or a soft cloth for approximately 15 seconds.
If you are using another nasal spray (e.g., a decongestant spray), wait 30 minutes after using nafarelin nasal spray before using the other nasal spray.
