Some children using nafarelin have had new or worsening mental problems. Call your doctor right away if your child has any unusual changes in mood or behavior (anger, aggression, crying, feeling restless or irritable).

Nafarelin may also cause seizures, especially in people who have had a seizure, epilepsy, a brain tumor, or blood vessel problems in the brain. Your risk of a seizure may also be higher if you take certain antidepressant medications.

You should not use nafarelin nasal if you have abnormal vaginal bleeding that has not been checked by a doctor.

Nafarelin nasal (for the nose) is used to treat central precocious puberty in boys and girls. Central precocious puberty is early sexual development that occurs at or before 8 years of age in girls or 9 years of age in boys, with bone development that is advanced for the child's age.

Nafarelin nasal is also used to treat endometriosis in women who are at least 18 years old.

You should not use this medicine if you are allergic to nafarelin or similar medicines such as goserelin, leuprolide, histrelin, or triptorelin.

If you are female, you should not use nafarelin nasal if you have:

  • abnormal vaginal bleeding that has not been checked by a doctor; or
  • if you are pregnant or breastfeeding.

Tell your doctor if you have ever had:

  • epilepsy or other seizure disorder;
  • mental illness;
  • a tumor or blood vessel problem in your brain;
  • abnormal vaginal bleeding that has not been checked by a doctor;
  • polycystic ovary disease;
  • low bone mineral density;
  • osteoporosis (in you or a family member); or
  • if you smoke or drink large amounts of alcohol.

Do not use nafarelin nasal if you are pregnant. It could harm the unborn baby. You may need to have a negative pregnancy test before starting this treatment.

Even though this medicine may cause you not to ovulate or have regular menstrual periods, you should use effective nonhormonal birth control to prevent pregnancy while you are using this medicine.

Nafarelin nasal can make hormonal birth control less effective, including birth control pills, injections, implants, skin patches, and vaginal rings. To prevent pregnancy while using nafarelin, use a barrier form of birth control: condom, diaphragm, cervical cap, or contraceptive sponge.

You should not breastfeed while using nafarelin nasal.

How should I use nafarelin nasal?

Your doctor will perform tests to make sure this medicine is the right treatment for your child's condition.

Follow all directions on your prescription label and read all medication guides or instruction sheets. Your doctor may occasionally change your dose. Use the medicine exactly as directed.

Do not miss any doses of this medicine. Skipping doses or not using nafarelin nasal correctly may cause a hormonal imbalance that could lead to unwanted side effects.

Read and carefully follow all Instructions for using the nasal spray. Ask your doctor or pharmacist if you do not understand these instructions.

Tilt your head slightly back when using the nasal spray. Use only the number of sprays your doctor has prescribed, and allow at least 30 seconds between sprays.

Your doctor will need to check your child's progress with frequent medical tests, especially during the first 6 to 8 weeks of using nafarelin nasal.

Nafarelin can increase certain hormones when you first start using this medicine. This may cause your child's symptoms of precocious puberty to get worse for a short time. Call your doctor if pubertal signs continue for longer than 1 month.

If you have regular menstrual periods, they should stop while you are using nafarelin nasal. Tell your doctor if your periods continue for longer than 1 month after you start using this medicine.

Do not use a nafarelin nasal spray bottle for longer than 30 days. The amount of medicine left in the bottle after 30 days of regular use will not be enough for another full dose. Get your prescription refilled before the 30 days are up so you don't run out of medicine.

Store nafarelin nasal in an upright position at room temperature, away from moisture, heat, and light. Do not freeze. Keep the bottle tightly capped when not in use.
