Precautions While Using This Medicine

All scheduled visits to the doctor should be kept, even if the medicine seems to be working properly and you feel well. This is especially important for children using the medicine for treatment of central precocious puberty, even if their condition improves. Their progress still must be checked by the doctor when they are no longer using the medicine.

For children treated for central precocious puberty - Tell the doctor if nafarelin does not stop puberty from progressing within 6 to 8 weeks. You may notice puberty progressing in your child for the first few weeks of therapy, but you should see signs that puberty is stopping within 4 weeks after your child begins nafarelin therapy.

For adult women treated for endometriosis -

• During the time you are receiving nafarelin, your menstrual period may not be regular or you may not have a menstrual period at all. This is to be expected when being treated with this medicine. If regular menstrual periods do not begin within 2 to 3 months after you stop using this medicine, check with your health care professional.
• To prevent pregnancy if you are sexually active during the time you are using nafarelin, you should use birth control methods that do not contain hormones, such as condoms or a diaphragm or a cervical cap with a spermicide. If you have any questions about this, check with your health care professional.
• Use a water-based vaginal lubricant product if dryness of the vagina causes problems, such as pain during sexual intercourse. Make sure the lubricant you choose can be used with a latex birth control device if you are using one. Some lubricants contain oils, which can break down the latex rubber of condoms, a cervical cap, or a diaphragm, and cause them to rip or tear.
• If you suspect you are pregnant, stop using this medicine and check with your doctor immediately . There is a chance that nafarelin could cause problems to the unborn baby if taken during a pregnancy.
