Uses for Lyza

Norethindrone is used to prevent pregnancy. It works by stopping a woman's egg from fully developing each month. The egg can no longer accept a sperm and fertilization (pregnancy) is prevented.

Norethindrone is also used to treat secondary amenorrhea (absence of menstrual periods in women who have previously had a menstrual period who are not pregnant), endometriosis, and irregular menstrual periods caused by hormonal imbalance.

No contraceptive method is 100 percent effective. Birth control methods such as having surgery to become sterile or not having sex are more effective than birth control pills. Discuss your options for birth control with your doctor.

This medicine does not protect against HIV infection or other sexually transmitted diseases. It will not help as emergency contraception, such as after unprotected sexual contact.

This medicine is available only with your doctor's prescription.

Before using Lyza

In deciding to use a medicine, the risks of taking the medicine must be weighed against the good it will do. This is a decision you and your doctor will make. For this medicine, the following should be considered:

Allergies

Tell your doctor if you have ever had any unusual or allergic reaction to this medicine or any other medicines. Also tell your health care professional if you have any other types of allergies, such as to foods, dyes, preservatives, or animals. For non-prescription products, read the label or package ingredients carefully.

Pediatric

Appropriate studies on the relationship of age to the effects of Ortho Micronor® tablets have not been performed in the pediatric population. However, pediatric-specific problems that would limit the usefulness of this medicine in teenagers are not expected. This medicine may be used for birth control in teenage females but should not be used before the start of menstruation.

Use of norethindrone acetate tablets is not recommended in children.

Geriatric

Appropriate studies on the relationship of age to the effects of norethindrone have not been performed in the geriatric population. This medicine should not be used in elderly women.

Breastfeeding

There are no adequate studies in women for determining infant risk when using this medication during breastfeeding. Weigh the potential benefits against the potential risks before taking this medication while breastfeeding.

Interactions with medicines

Although certain medicines should not be used together at all, in other cases two different medicines may be used together even if an interaction might occur. In these cases, your doctor may want to change the dose, or other precautions...
