Why is Nafarelin acetate prescribed?

Nafarelin acetate is used to relieve the symptoms of endometriosis, including menstrual cramps or low back pain during menstruation, painful intercourse, painful bowel movements, and abnormal and heavy menstrual bleeding. Endometriosis is a condition in which fragments of the tissue that lines the uterus are found in the other parts of the pelvic cavity. Nafarelin acetate is also used to treat unusually early puberty in children of both sexes.

Some doctors prescribe Nafarelin acetate as a contraceptive for both men and women.

Most important fact about Nafarelin acetate

Although Nafarelin acetate usually stops ovulation and menstruation, there is still a possibility of becoming pregnant while taking the medication. Since Nafarelin acetate could harm a fetus, be sure to use a nonhormonal, barrier form of birth control such as condoms and diaphragms. If you should become pregnant, stop the drug and tell your doctor immediately.

How should you take Nafarelin acetate?

Take Nafarelin acetate exactly as prescribed.

Nafarelin acetate is sprayed into one nostril in the morning and the other nostril in the evening. If your doctor increases the dose, you will spray Nafarelin acetate into both nostrils morning and evening.

Try not to sneeze during or immediately after spraying Nafarelin acetate into your nostrils.

Wait 2 hours after taking Nafarelin acetate before using a decongestant spray or drops.

You should not use Nafarelin acetate for more than 6 months. If your symptoms recur after you have finished taking the medication, your doctor will usually not prescribe it again.

Before you use each new bottle of Nafarelin acetate for the first time, you have to prime the spray pump. Remove the plastic wrap from the spray bottle and hold it in an upright position pointed away from you. Applying pressure evenly to the "shoulders," push down quickly and firmly 7 to 10 times. Usually the spray will appear after about 7 pumps. Priming need only be done once.

To use the Nafarelin acetate Nasal Spray Unit, follow these steps:

1. Gently blow your nose to clear both nostrils.
2. Remove the safety clip and clear plastic dust cover from the spray bottle.
3. Bend your head forward a little and put the spray tip into one nostril. Close the other nostril with your finger.
4. Applying pressure evenly to the "shoulders," quickly and firmly pump the sprayer one time while gently sniffing in.
5. Remove the sprayer from your nose and tilt your head backwards for a few seconds. Do not take additional sprays unless your doctor has specifically instructed you to do so.
6. Wipe tip of the pump with a soft cloth or tissue after each use.

--If you miss a dose...

Take it as soon as you remember. If it is almost time for your next dose, skip the one you missed and go back to your regular schedule. Never try to "catch up" by doubling the dose.

Try not to miss any doses. If you miss successive doses, bleeding and ovulation can start again, and you could become pregnant.
